-Instructions on how to build FreeType with your own build tool
-==============================================================
-
-See the file `CUSTOMIZE' to learn how to customize FreeType to
-specific environments.
-
-
-I. Standard procedure
----------------------
-
- * If you use macro names for FreeType header files (while mandatory
- in earlier versions, this is now optional since FreeType version
- 2.6.1) it is necessary to disable pre-compiled headers. This is
- very important for Visual C++, because lines like
-
- #include FT_FREETYPE_H
-
- are not correctly supported by this compiler while being ISO C
- compliant!
-
- * You need to add the directory `include' to your include path when
- compiling the library.
-
- * FreeType 2 is made of several components; each of them is located
- in a subdirectory of `freetype/src'. For example,
- `freetype/src/truetype/' contains the TrueType font driver.
-
- * DO NOT COMPILE ALL C FILES! Rather, compile the following ones.
-
- -- base components (required)
-
- src/base/ftsystem.c
- src/base/ftinit.c
- src/base/ftdebug.c
-
- src/base/ftbase.c
-
- src/base/ftbbox.c -- recommended, see <ftbbox.h>
- src/base/ftglyph.c -- recommended, see <ftglyph.h>
-
- src/base/ftbdf.c -- optional, see <ftbdf.h>
- src/base/ftbitmap.c -- optional, see <ftbitmap.h>
- src/base/ftcid.c -- optional, see <ftcid.h>
- src/base/ftfstype.c -- optional
- src/base/ftgasp.c -- optional, see <ftgasp.h>
- src/base/ftgxval.c -- optional, see <ftgxval.h>
- src/base/ftmm.c -- optional, see <ftmm.h>
- src/base/ftotval.c -- optional, see <ftotval.h>
- src/base/ftpatent.c -- optional
- src/base/ftpfr.c -- optional, see <ftpfr.h>
- src/base/ftstroke.c -- optional, see <ftstroke.h>
- src/base/ftsynth.c -- optional, see <ftsynth.h>
- src/base/fttype1.c -- optional, see <t1tables.h>
- src/base/ftwinfnt.c -- optional, see <ftwinfnt.h>
-
- src/base/ftmac.c -- only on the Macintosh
-
- -- font drivers (optional; at least one is needed)
-
- src/bdf/bdf.c -- BDF font driver
- src/cff/cff.c -- CFF/OpenType font driver
- src/cid/type1cid.c -- Type 1 CID-keyed font driver
- src/pcf/pcf.c -- PCF font driver
- src/pfr/pfr.c -- PFR/TrueDoc font driver
- src/sfnt/sfnt.c -- SFNT files support
- (TrueType & OpenType)
- src/truetype/truetype.c -- TrueType font driver
- src/type1/type1.c -- Type 1 font driver
- src/type42/type42.c -- Type 42 font driver
- src/winfonts/winfnt.c -- Windows FONT / FNT font driver
-
- -- rasterizers (optional; at least one is needed for vector
- formats)
-
- src/raster/raster.c -- monochrome rasterizer
- src/sdf/sdf.c -- Signed Distance Field driver
- src/smooth/smooth.c -- anti-aliasing rasterizer
-
- -- auxiliary modules (optional)
-
- src/autofit/autofit.c -- auto hinting module
- src/cache/ftcache.c -- cache sub-system (in beta)
- src/gzip/ftgzip.c -- support for compressed fonts (.gz)
- src/lzw/ftlzw.c -- support for compressed fonts (.Z)
- src/bzip2/ftbzip2.c -- support for compressed fonts (.bz2)
- src/gxvalid/gxvalid.c -- TrueTypeGX/AAT table validation
- src/otvalid/otvalid.c -- OpenType table validation
- src/psaux/psaux.c -- PostScript Type 1 parsing
- src/pshinter/pshinter.c -- PS hinting module
- src/psnames/psnames.c -- PostScript glyph names support
-
-
- Notes:
-
- `ftcache.c' needs `ftglyph.c'
- `ftfstype.c' needs `fttype1.c'
- `ftglyph.c' needs `ftbitmap.c'
- `ftstroke.c' needs `ftglyph.c'
- `ftsynth.c' needs `ftbitmap.c'
-
- `cff.c' needs `sfnt.c', `pshinter.c', and `psnames.c'
- `truetype.c' needs `sfnt.c' and `psnames.c'
- `type1.c' needs `psaux.c' `pshinter.c', and `psnames.c'
- `type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c'
- `type42.c' needs `truetype.c'
-
- Please consult the central `include/freetype/config/ftoption.h'
- configuration file for details on additional libraries necessary
- for some optional features.
-
-
- Read the file `CUSTOMIZE' in case you want to compile only a subset
- of the drivers, renderers, and optional modules; a detailed
- description of the various base extension is given in the top-level
- file `modules.cfg'.
-
- You are done. In case of problems, see the archives of the FreeType
- development mailing list.
-
-
-II. Support for flat-directory compilation
-------------------------------------------
-
- It is possible to put all FreeType 2 source files into a single
- directory, with the *exception* of the `include' hierarchy.
-
- 1. Copy all files in current directory
-
- cp freetype/src/base/*.[hc] .
- cp freetype/src/raster1/*.[hc] .
- cp freetype/src/smooth/*.[hc] .
- etc.
-
- 2. Compile sources
-
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
- etc.
-
- You don't need to define the FT_FLAT_COMPILATION macro (as this
- was required in previous releases of FreeType 2).

-This document contains instructions on how to cross-build the FreeType
-library on Unix systems, for example, building binaries for Linux/MIPS
-on FreeBSD/i386. Before reading this document, please consult the
-file `INSTALL.UNIX' for required tools and the basic self-building
-procedure.
-
-
- 1. Required Tools
- -----------------
-
- For self-building the FreeType library on a Unix system, GNU Make
- 3.81 or newer is required. `INSTALL.UNIX' contains hints how to
- check the installed `make'.
-
- The GNU C compiler to cross-build the target system is required.
- Currently, using a non-GNU cross compiler is untested. The cross
- compiler is expected to be installed with a system prefix. For
- example, if your building system is FreeBSD/i386 and the target
- system is Linux/MIPS, the cross compiler should be installed with
- the name `mips-ip22-linuxelf-gcc'.
-
- A C compiler for a self-build is required also, to build a tool
- (`apinames') that is executed during the build procedure. Non-GNU
- self compilers are acceptable, but such a setup is untested.
-
-
- 2. Configuration
- ----------------
-
- 2.1. Building and target system
-
- To configure a cross-build, the options `--host=<system>' and
- `--build=<system>' must be passed to the `configure' script.
- For example, if your build system is FreeBSD/i386 and the target
- system is Linux/MIPS, say
-
- ./configure \
- --build=i386-unknown-freebsd \
- --host=mips-ip22-linuxelf \
- [other options]
-
- It should be noted that `--host=<system>' specifies the system
- where the built binaries will be executed, not the system where
- the build actually happens. Older versions of GNU autoconf use
- the option pair `--host=' and `--target='. This is broken and
- doesn't work. Similarly, an explicit CC specification like
-
- env CC=mips-ip22-linux-gcc ./configure # BAD
-
- or
-
- env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD
-
- doesn't work either; such a configuration confuses the
- `configure' script while trying to find the cross and native C
- compilers.
-
-
- 2.2. The prefix to install FreeType2
-
- Setting `--prefix=<prefix>' properly is important. The prefix
- to install FreeType2 is written into the `freetype-config'
- script and `freetype2.pc' configuration file.
-
- If the built FreeType 2 library is used as a part of the
- cross-building system, the prefix is expected to be different
- from the self-building system. For example, a configuration
- with `--prefix=/usr/local' installs binaries into the
- system-wide `/usr/local' directory, which then can't be executed
- due to the incorrect architecture. This causes confusion in
- configuration of all applications that use FreeType2. Instead,
- use a prefix to install the cross-build into a separate system
- tree, for example, `--prefix=/usr/local/mips-ip22-linux/'.
-
- On the other hand, if the built FreeType 2 library is used as a
- part of the target system, the prefix to install should reflect
- the file system structure of the target system.
-
-
- 2.3. Library dependencies
-
- FreeType normally depends on external libraries like `libpng' or
- `libharfbuzz'. The easiest case is to deactivate all such
- dependencies using the `--without-XXX' configuration options.
- However, if you want to use those libraries, you should ensure
- that they are available both on the target system and as
- (cross-compiled) libraries on the build system.
-
- FreeType uses `pkg-config' to find most of the libraries; the
- other libraries it links to are expected in the standard system
- directories. Since the default pkg-config's meta-information
- files (like `harfbuzz.pc') of the build platform don't work, use
- one of the two possible solutions below.
-
- o Use pkg-config's meta-information files that are adjusted to
- cross-compile and cross-link with the target platform's
- libraries. Make sure those files are found before the build
- system's default files. Example:
-
- ./configure \
- --build=i386-unknown-freebsd \
- --host=mips-ip22-linuxelf \
- PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \
- [other options]
-
- See the manpage of `pkg-config' for more details.
-
- o Set variables like LIBPNG_LIBS as additional options to the
- `configure' script, overriding the values `pkg-config' would
- provide. `configure --help' shows the available environment
- variables. Example:
-
- ./configure \
- --build=i386-unknown-freebsd \
- --host=mips-ip22-linuxelf \
- LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \
- LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \
- [other options]
-
-
- 3. Building command
- -------------------
-
- If the configuration finishes successfully, invoking GNU make
- builds FreeType2. Just say
-
- make
-
- or
-
- gmake
-
- depending on the name the GNU make binary actually has.
-
-
- 4. Installation
- ---------------
-
- Saying
-
- make install
-
- as usual to install FreeType2 into the directory tree specified by
- the argument of the `--prefix' option.
-
- As noted in section 2.2, FreeType2 is sometimes configured to be
- installed into the system directory of the target system, and
- should not be installed in the cross-building system. In such
- cases, the make variable `DESTDIR' is useful to change the root
- directory in the installation. For example, after
-
- make DESTDIR=/mnt/target_system_root/ install
-
- the built FreeType2 library files are installed into the directory
- `/mnt/target_system_root/<prefix_in_configure>/lib'.
-
-
- 5. TODO
- -------
-
- Cross building between Cygwin (or MSys) and Unix must be tested.

-This document contains instructions how to build the FreeType library
-on non-Unix systems with the help of GNU Make. Note that if you are
-running Cygwin or MinGW/MSYS in Windows, you should follow the
-instructions in the file `INSTALL.UNIX' instead.
-
-
- FreeType 2 includes a powerful and flexible build system that allows
- you to easily compile it on a great variety of platforms from the
- command line. To do so, just follow these simple instructions.
-
- 1. Install GNU Make
- -------------------
-
- The FreeType 2 build system relies on many features special to GNU
- Make.
-
- NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE', SO REALLY
- INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
-
- Note that make++, a make tool written in Perl, supports enough
- features of GNU make to compile FreeType. See
-
- https://makepp.sourceforge.net
-
- for more information; you need version 2.0 or newer, and you must
- pass option `--norc-substitution'.
-
- Make sure that you are invoking GNU Make from the command line, by
- typing something like:
-
- make -v
-
- to display its version number.
-
- VERSION 3.81 OR NEWER IS NEEDED!
-
-
- 2. Invoke `make'
- ----------------
-
- Go to the root directory of FreeType 2, then simply invoke GNU
- Make from the command line. This will launch the FreeType 2 host
- platform detection routines. A summary will be displayed, for
- example, on Win32.
-
-
- ==============================================================
- FreeType build system -- automatic system detection
-
- The following settings are used:
-
- platform windows
- compiler gcc
- configuration directory .\builds\windows
- configuration rules .\builds\windows\w32-gcc.mk
-
- If this does not correspond to your system or settings please
- remove the file 'config.mk' from this directory then read the
- INSTALL file for help.
-
- Otherwise, simply type 'make' again to build the library
- or 'make refdoc' to build the API reference (the latter needs
- Python >= 3.5).
- =============================================================
-
-
- If the detected settings correspond to your platform and compiler,
- skip to step 5. Note that if your platform is completely alien to
- the build system, the detected platform will be `ansi'.
-
-
- 3. Configure the build system for a different compiler
- ------------------------------------------------------
-
- If the build system correctly detected your platform, but you want
- to use a different compiler than the one specified in the summary
- (for most platforms, gcc is the default compiler), invoke GNU Make
- with
-
- make setup <compiler>
-
- Examples:
-
- to use Visual C++ on Win32, type: `make setup visualc'
- to use Borland C++ on Win32, type `make setup bcc32'
- to use Watcom C++ on Win32, type `make setup watcom'
- to use Intel C++ on Win32, type `make setup intelc'
- to use LCC-Win32 on Win32, type: `make setup lcc'
- to use Watcom C++ on OS/2, type `make setup watcom'
- to use VisualAge C++ on OS/2, type `make setup visualage'
-
- The <compiler> name to use is platform-dependent. The list of
- available compilers for your system is available in the file
- `builds/<system>/detect.mk'.
-
- If you are satisfied by the new configuration summary, skip to
- step 5.
-
-
- 3a. Use clang instead of gcc
- ----------------------------
-
- The `clang' compiler can use FreeType's setup for `gcc'; it is
- sufficient to set the `CC' variable, for example
-
- make CC=clang
-
-
- 3b. Compiling with a C++ compiler
- ---------------------------------
-
- FreeType can be built with a C++ compiler, for example
-
- make CC="g++"
-
- If `clang++' should be used it is necessary to also override the
- `ANSIFLAGS' variable:
-
- make CC="clang++" ANSIFLAGS=""
-
-
- 4. Configure the build system for an unknown platform/compiler
- --------------------------------------------------------------
-
- The auto-detection/setup phase of the build system copies a file
- to the current directory under the name `config.mk'.
-
- For example, on OS/2+gcc, it would simply copy
- `builds/os2/os2-gcc.mk' to `./config.mk'.
-
- If for some reason your platform isn't correctly detected, copy
- manually the configuration sub-makefile to `./config.mk' and go to
- step 5.
-
- Note that this file is a sub-Makefile used to specify Make
- variables for compiler and linker invocation during the build.
- You can easily create your own version from one of the existing
- configuration files, then copy it to the current directory under
- the name `./config.mk'.
-
-
- 5. Build the library
- --------------------
-
- The auto-detection/setup phase should have copied a file in the
- current directory, called `./config.mk'. This file contains
- definitions of various Make variables used to invoke the compiler
- and linker during the build. [It has also generated a file called
- `ftmodule.h' in the objects directory (which is normally
- `<toplevel>/objs/'); please read the file `docs/CUSTOMIZE' for
- customization of FreeType.]
-
- To launch the build, simply invoke GNU Make again: The top
- Makefile will detect the configuration file and run the build with
- it. If you have used variables in step 3, you must use the same
- variables here, too.
-
-
- Final note
-
- The above instructions build a _statically_ linked library of the
- font engine in the `objs' directory. On Windows, you can build a
- DLL either with MinGW (within an MSYS shell, following the
- instructions in `INSTALL.UNIX'), or you use one of the Visual C++
- project files; see the subdirectories of `builds/windows'. For
- everything else, you are on your own, and you might follow the
- instructions in `INSTALL.ANY' to create your own Makefiles.

-This document contains instructions on how to build the FreeType
-library on Unix systems. This also works for emulations like Cygwin
-or MSys on Win32:
-
-
- 1. Ensure that you are using GNU Make
- -------------------------------------
-
- The FreeType build system _exclusively_ works with GNU Make. You
- will not be able to compile the library with the instructions
- below using any other alternative (including BSD Make).
-
- Check that you have GNU make by running the command:
-
- make -v
-
- This should dump some text that begins with:
-
- GNU Make <version number>
- Copyright (C) <year> Free Software Foundation Inc.
-
- Note that version 3.81 or higher is *required* or the build will
- fail.
-
- It is also fine to have GNU Make under another name (e.g. 'gmake')
- if you use the MAKE variable as described below.
-
- As a special exception, 'makepp' can also be used to build
- FreeType 2. See the file docs/MAKEPP for details.
-
- For builds with `cmake' please check file `CMakeLists.txt'; this
- is a contributed file not directly supported by the FreeType team.
-
-
- 2. Regenerate the configure script if needed
- --------------------------------------------
-
- This only applies if you are building a git snapshot or checkout,
- *not* if you grabbed the sources of an official release.
-
- You need to invoke the `autogen.sh' script in the top-level
- directory in order to create the `configure' script for your
- platform. Normally, this simply means typing:
-
- sh autogen.sh
-
- In case of problems, you may need to install or upgrade Automake,
- Autoconf or Libtool. See `README.git' in the top-level directory
- for more information.
-
-
- 3. Build and install the library
- --------------------------------
-
- Say
-
- ./configure --help
-
- to see the list of possible configuration options and important
- environment variables. The ./configure script will detect some
- prerequisite system libraries (libpng, brotli, etc.) if their
- headers are available at the default locations.
-
- The following should work on all Unix systems where the `make'
- command invokes GNU Make:
-
- ./configure [options]
- make
- make install (as root)
-
- The default installation path is `/usr/local'. It can be changed
- with the `--prefix=<path>' option. Example:
-
- ./configure --prefix=/usr
-
- When using a different command to invoke GNU Make, use the MAKE
- variable. For example, if `gmake' is the command to use on your
- system, do something like:
-
- MAKE=gmake ./configure [options]
- gmake
- gmake install (as root)
-
- If this still doesn't work, there must be a problem with your
- system (e.g., you are using a very old version of GNU Make).
-
- For library identification, FreeType's `configure' script uses the
- `pkg-config' interface: Assuming it needs library `foo', it calls
- the `pkg-config' program to find information on library `foo',
- which in turn looks for a `foo.pc' file installed at the system.
- Some platforms, however, don't come with `pkg-support'; you then
- have to use environment variables as described by `configure
- --help'. Example:
-
- LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \
- LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \
- configure ...
-
- It is possible to compile FreeType in a different directory.
- Assuming the FreeType source files in directory `/src/freetype' a
- compilation in directory `foo' works as follows:
-
- cd foo
- /src/freetype/configure [options]
- make
- make install
-
-
- 3.1 Interdependency with HarfBuzz
- .................................
-
- Note that there is a chicken-and-egg problem currently since the
- HarfBuzz library (used by the auto-hinter to improve support of
- OpenType fonts) depends on FreeType, which can be solved as
- follows in case HarfBuzz is not yet installed on your system.
-
- 1. Call FreeType's `configure' script with option
- `--without-harfbuzz', then compile and install FreeType.
-
- 2. Compile and install HarfBuzz.
-
- 3. Call FreeType's `configure' script without option
- `--without-harfbuzz' (after executing `make distclean'), then
- compile and install FreeType again.

+# Instructions on how to build FreeType with your own build tool
+
+See the file [docs/CUSTOMIZE][CUSTOMIZE] to learn how to
+customize FreeType to specific environments.
+
+
+## A. Standard procedure
+
+If you use macro names for FreeType header files (while mandatory
+in earlier versions, this is now optional since FreeType version
+2.6.1) it is necessary to disable pre-compiled headers. This is
+very important for Visual C++, because lines like
+
+```C
+ #include FT_FREETYPE_H
+```
+are not correctly supported by this compiler while being ISO C
+compliant!
+
+You need to add the directory `include` to your include path when
+compiling the library.
+
+FreeType 2 is made of several components; each of them is located
+in a subdirectory of `freetype/src`. For example,
+`freetype/src/truetype/` contains the TrueType font driver.
+
+## DO NOT COMPILE ALL C FILES! Rather, compile the following ones.
+
+### base components (required):
+
+ src/base/ftsystem.c
+ src/base/ftinit.c
+ src/base/ftdebug.c

+
+
+## Notes:
+
+ `ftcache.c` needs `ftglyph.c`
+ `ftfstype.c` needs `fttype1.c`
+ `ftglyph.c` needs `ftbitmap.c`
+ `ftstroke.c` needs `ftglyph.c`

+ `truetype.c` needs `sfnt.c` and `psnames.c`
+ `type1.c` needs `psaux.c` `pshinter.c`, and `psnames.c`
+ `type1cid.c` needs `psaux.c`, `pshinter.c`, and `psnames.c`
+ `type42.c` needs `truetype.c`
+
+Please consult the central `include/freetype/config/ftoption.h`
+configuration file for details on additional libraries necessary
+for some optional features.
+
+Read the file `CUSTOMIZE` in case you want to compile only a subset
+of the drivers, renderers, and optional modules; a detailed
+description of the various base extension is given in the top-level
+file `modules.cfg`.
+
+You are done. In case of problems, see the archives of the FreeType
+development mailing list.
+
+
+## B. Support for flat-directory compilation
+
+It is possible to put all FreeType 2 source files into a single
+directory, with the *exception* of the `include` hierarchy.
+
+Copy all files in current directory
+
+ cp freetype/src/base/*.[hc] .
+ cp freetype/src/raster1/*.[hc] .
+ cp freetype/src/smooth/*.[hc] .
+ etc.
+
+Compile sources
+
+ cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
+ cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
+ cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
+ cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
+ etc.
+
+You don't need to define the FT_FLAT_COMPILATION macro (as this
+was required in previous releases of FreeType 2).

+# Cross-Compiling FreeType
+
+This document contains instructions on how to cross-build the FreeType
+library on Unix systems, for example, building binaries for Linux/MIPS
+on FreeBSD/i386. Before reading this document, please consult the
+file [INSTALL_UNIX.md] for required tools and the basic self-building
+procedure.
+
+
+## 1. Required Tools
+
+For self-building the FreeType library on a Unix system, GNU Make
+3.81 or newer is required. [INSTALL_UNIX.md contains hints how to
+check the installed `make`.
+
+The GNU C compiler to cross-build the target system is required.
+Currently, using a non-GNU cross compiler is untested. The cross
+compiler is expected to be installed with a system prefix. For
+example, if your building system is FreeBSD/i386 and the target
+system is Linux/MIPS, the cross compiler should be installed with
+the name `mips-ip22-linuxelf-gcc`.
+
+A C compiler for a self-build is required also, to build a tool
+(`apinames`) that is executed during the build procedure. Non-GNU
+self compilers are acceptable, but such a setup is untested.
+
+
+## 2. Configuration
+
+### 2.1 Building and target system
+
+To configure a cross-build, the options `--host=<system>` and
+`--build=<system>` must be passed to the `configure` script.
+For example, if your build system is FreeBSD/i386 and the target
+system is Linux/MIPS, say
+
+```bash
+ ./configure \
+ --build=i386-unknown-freebsd \
+ --host=mips-ip22-linuxelf \
+ [other options]
+```
+
+It should be noted that `--host=<system>` specifies the system
+where the built binaries will be executed, not the system where
+the build actually happens. Older versions of GNU autoconf use
+the option pair `--host=` and `--target=`. This is broken and
+doesn't work. Similarly, an explicit CC specification like
+
+```bash
+ env CC=mips-ip22-linux-gcc ./configure # BAD
+```
+or
+
+```bash
+ env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD
+```
+
+doesn't work either; such a configuration confuses the
+`configure` script while trying to find the cross and native C
+compilers.
+
+
+### 2.2. The prefix to install FreeType2
+
+Setting `--prefix=<prefix>` properly is important. The prefix
+to install FreeType2 is written into the `freetype-config`
+script and `freetype2.pc` configuration file.
+
+If the built FreeType 2 library is used as a part of the
+cross-building system, the prefix is expected to be different
+from the self-building system. For example, a configuration
+with `--prefix=/usr/local` installs binaries into the
+system-wide `/usr/local` directory, which then can't be executed
+due to the incorrect architecture. This causes confusion in
+configuration of all applications that use FreeType2. Instead,
+use a prefix to install the cross-build into a separate system
+tree, for example, `--prefix=/usr/local/mips-ip22-linux/`.
+
+On the other hand, if the built FreeType 2 library is used as a
+part of the target system, the prefix to install should reflect
+the file system structure of the target system.
+
+
+### 2.3. Library dependencies
+
+FreeType normally depends on external libraries like `libpng` or
+`libharfbuzz`. The easiest case is to deactivate all such
+dependencies using the `--without-XXX` configuration options.
+However, if you want to use those libraries, you should ensure
+that they are available both on the target system and as
+(cross-compiled) libraries on the build system.
+
+FreeType uses `pkg-config` to find most of the libraries; the
+other libraries it links to are expected in the standard system
+directories. Since the default pkg-config's meta-information
+files (like `harfbuzz.pc`) of the build platform don't work, use
+one of the two possible solutions below.
+
+- Use pkg-config's meta-information files that are adjusted to
+ cross-compile and cross-link with the target platform's
+ libraries. Make sure those files are found before the build
+ system's default files. Example:
+ ```bash
+ ./configure \
+ --build=i386-unknown-freebsd \
+ --host=mips-ip22-linuxelf \
+ PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \
+ [other options]
+ ```
+
+ See the manpage of `pkg-config` for more details.
+
+- Set variables like LIBPNG_LIBS as additional options to the
+ `configure` script, overriding the values `pkg-config` would
+ provide. `configure --help` shows the available environment
+ variables. Example:
+ ```bash
+ ./configure \
+ --build=i386-unknown-freebsd \
+ --host=mips-ip22-linuxelf \
+ LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \
+ LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \
+ [other options]
+ ```
+
+
+## 3. Building command
+
+If the configuration finishes successfully, invoking GNU make
+builds FreeType2. Just say
+
+ make
+
+or
+
+ gmake
+
+depending on the name the GNU make binary actually has.
+
+
+## 4. Installation
+
+Saying
+
+ make install
+
+as usual to install FreeType2 into the directory tree specified by
+the argument of the `--prefix` option.
+
+As noted in section 2.2, FreeType2 is sometimes configured to be
+installed into the system directory of the target system, and
+should not be installed in the cross-building system. In such
+cases, the make variable `DESTDIR` is useful to change the root
+directory in the installation. For example, after
+
+```bash
+ make DESTDIR=/mnt/target_system_root/ install
+```
+
+the built FreeType2 library files are installed into the directory
+`/mnt/target_system_root/<prefix_in_configure>/lib`.
+
+
+## 5. TODO
+
+Cross building between Cygwin (or MSys) and Unix must be tested.

+# Compiling FreeType with GNU Make
+
+This document contains instructions how to build the FreeType library
+on non-Unix systems with the help of GNU Make. Note that if you are
+running Cygwin or MinGW/MSYS in Windows, you should follow the
+instructions in the file [INSTALL_UNIX.md] instead.
+
+
+FreeType 2 includes a powerful and flexible build system that allows
+you to easily compile it on a great variety of platforms from the
+command line. To do so, just follow these simple instructions.
+
+## 1. Install GNU Make
+
+The FreeType 2 build system relies on many features special to GNU
+Make.
+
+NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE`, SO REALLY
+INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
+
+Note that make++, a make tool written in Perl, supports enough
+features of GNU make to compile FreeType. See
+
+>https://makepp.sourceforge.net
+
+for more information; you need version 2.0 or newer, and you must
+pass option `--norc-substitution`.
+
+Make sure that you are invoking GNU Make from the command line, by
+typing something like:
+
+ make -v
+
+to display its version number.
+
+VERSION 3.81 OR NEWER IS NEEDED!
+
+
+## 2. Invoke `make`
+
+Go to the root directory of FreeType 2, then simply invoke GNU
+Make from the command line. This will launch the FreeType 2 host
+platform detection routines. A summary will be displayed, for
+example, on Win32.
+
+ FreeType build system -- automatic system detection
+
+ The following settings are used:
+
+ platform windows
+ compiler gcc
+ configuration directory .\builds\windows
+ configuration rules .\builds\windows\w32-gcc.mk
+
+ If this does not correspond to your system or settings please
+ remove the file 'config.mk' from this directory then read the
+ INSTALL file for help.
+
+ Otherwise, simply type 'make' again to build the library
+ or 'make refdoc' to build the API reference (the latter needs
+ Python >= 3.5).
+
+
+If the detected settings correspond to your platform and compiler,
+skip to step 5. Note that if your platform is completely alien to
+the build system, the detected platform will be `ansi`.
+
+
+## 3. Configure the build system for a different compiler
+
+If the build system correctly detected your platform, but you want
+to use a different compiler than the one specified in the summary
+(for most platforms, gcc is the default compiler), invoke GNU Make
+with
+
+ make setup <compiler>
+
+Examples:
+
+ to use Visual C++ on Win32, type: `make setup visualc`
+ to use Borland C++ on Win32, type `make setup bcc32`
+ to use Watcom C++ on Win32, type `make setup watcom`
+ to use Intel C++ on Win32, type `make setup intelc`
+ to use LCC-Win32 on Win32, type: `make setup lcc`
+ to use Watcom C++ on OS/2, type `make setup watcom`
+ to use VisualAge C++ on OS/2, type `make setup visualage`
+
+
+The `<compiler>` name to use is platform-dependent. The list of
+available compilers for your system is available in the file
+`builds/<system>/detect.mk`.
+
+If you are satisfied by the new configuration summary, skip to
+step 5.
+
+### 3a. Use clang instead of gcc
+
+The `clang` compiler can use FreeType's setup for `gcc`; it is
+sufficient to set the `CC` variable, for example
+
+ make CC=clang
+
+### 3b. Compiling with a C++ compiler
+
+FreeType can be built with a C++ compiler, for example
+
+ make CC="g++"
+
+If `clang++` should be used it is necessary to also override the
+`ANSIFLAGS` variable:
+
+ make CC="clang++" ANSIFLAGS=""
+
+
+## 4. Configure the build system for an unknown platform/compiler
+
+The auto-detection/setup phase of the build system copies a file
+to the current directory under the name `config.mk`.
+
+For example, on OS/2+gcc, it would simply copy
+`builds/os2/os2-gcc.mk` to `./config.mk`.
+
+If for some reason your platform isn't correctly detected, copy
+manually the configuration sub-makefile to `./config.mk` and go to
+step 5.
+
+Note that this file is a sub-Makefile used to specify Make
+variables for compiler and linker invocation during the build.
+You can easily create your own version from one of the existing
+configuration files, then copy it to the current directory under
+the name `./config.mk`.
+
+
+## 5. Build the library
+
+The auto-detection/setup phase should have copied a file in the
+current directory, called `./config.mk`. This file contains
+definitions of various Make variables used to invoke the compiler
+and linker during the build. [It has also generated a file called
+`ftmodule.h` in the objects directory (which is normally
+`<toplevel>/objs/`); please read the file [docs/CUSTOMIZE][CUSTOMIZE]
+for customization of FreeType.]
+
+To launch the build, simply invoke GNU Make again: The top
+Makefile will detect the configuration file and run the build with
+it. If you have used variables in step 3, you must use the same
+variables here, too.
+
+
+Final note
+
+The above instructions build a _statically_ linked library of the
+font engine in the `objs` directory. On Windows, you can build a
+DLL either with MinGW (within an MSYS shell, following the
+instructions in `INSTALL.UNIX`), or you use one of the Visual C++
+project files; see the subdirectories of `builds/windows`. For
+everything else, you are on your own, and you might follow the
+instructions in `INSTALL.ANY` to create your own Makefiles.

+# Compiling FreeType on Mac OS X
+
+Please follow the instructions in INSTALL.UNIX to install FreeType on
+Mac OS X.
+
+Currently FreeType2 functions based on some deprecated Carbon APIs
+return `FT_Err_Unimplemented_Feature` always, even if FreeType2 is
+configured and built on the system that deprecated Carbon APIs are
+available. To enable deprecated FreeType2 functions as far as
+possible, replace `src/base/ftmac.` by `builds/mac/ftmac.c`.
+
+Starting with Mac OS X 10.5, gcc defaults the deployment target to
+10.5. In previous versions of Mac OS X, this defaulted to 10.1. If
+you want your built binaries to run only on 10.5, this change does not
+concern you. If you want them to also run on older versions of Mac
+OS X, then you must either set the MACOSX_DEPLOYMENT_TARGET
+environment variable or pass `-mmacosx-version-min` to gcc. You
+should specify the oldest version of Mac OS you want the code to run
+on. For example, if you use Bourne shell:
+
+```bash
+ export MACOSX_DEPLOYMENT_TARGET=10.2
+```
+
+or, if you use C shell:
+
+```bash
+ setenv MACOSX_DEPLOYMENT_TARGET 10.2
+```
+
+Alternatively, you could pass `-mmacosx-version-min=10.2` to gcc.
+
+Here the number 10.2 is the lowest version that the built binaries can
+run on. In the above cases, the built binaries will run on Mac OS X
+10.2 and later, but _not_ earlier. If you want to run on earlier, you
+have to set lower version, e.g., 10.0.
+
+For classic Mac OS (Mac OS 7, 8, 9) please refer to builds/mac/README.

+# Building FreeType on Unix Systems
+
+This also works for emulations like Cygwin or MSys on Win32:
+
+
+## 1. Ensure that you are using GNU Make
+
+The FreeType build system _exclusively_ works with GNU Make. You
+will not be able to compile the library with the instructions
+below using any other alternative (including BSD Make).
+
+Check that you have GNU make by running the command:
+
+ make -v
+
+This should dump some text that begins with:
+
+ GNU Make <version number>
+ Copyright (C) <year> Free Software Foundation Inc.
+
+Note that version 3.81 or higher is *required* or the build will
+fail.
+
+It is also fine to have GNU Make under another name (e.g. 'gmake')
+if you use the MAKE variable as described below.
+
+As a special exception, 'makepp' can also be used to build
+FreeType 2. See the file `docs/MAKEPP` for details.
+
+For builds with `cmake` please check file `CMakeLists.txt`; this
+is a contributed file not directly supported by the FreeType team.
+
+
+## 2. Regenerate the configure script if needed
+
+This only applies if you are building a git snapshot or checkout,
+*not* if you grabbed the sources of an official release.
+
+You need to invoke the `autogen.sh` script in the top-level
+directory in order to create the `configure` script for your
+platform. Normally, this simply means typing:
+```bash
+ sh autogen.sh
+```
+
+In case of problems, you may need to install or upgrade Automake,
+Autoconf or Libtool. See [INSTALL.md] for more information.
+
+
+## 3. Build and install the library
+
+Say
+```bash
+ ./configure --help
+```
+
+to see the list of possible configuration options and important
+environment variables. The `./configure` script will detect some
+prerequisite system libraries (libpng, brotli, etc.) if their
+headers are available at the default locations.
+
+The following should work on all Unix systems where the `make`
+command invokes GNU Make:
+
+```bash
+ ./configure [options]
+ make
+ make install (as root)
+```
+
+The default installation path is `/usr/local`. It can be changed
+with the `--prefix=<path>` option. Example:
+
+```bash
+ ./configure --prefix=/usr
+```
+
+When using a different command to invoke GNU Make, use the MAKE
+variable. For example, if `gmake` is the command to use on your
+system, do something like:
+
+```bash
+ MAKE=gmake ./configure [options]
+ gmake
+ gmake install (as root)
+```
+
+If this still doesn't work, there must be a problem with your
+system (e.g., you are using a very old version of GNU Make).
+
+For library identification, FreeType's `configure` script uses the
+`pkg-config` interface: Assuming it needs library `foo`, it calls
+the `pkg-config` program to find information on library `foo`,
+which in turn looks for a `foo.pc` file installed at the system.
+Some platforms, however, don't come with `pkg-support`; you then
+have to use environment variables as described by `configure
+--help`. Example:
+
+```bash
+ LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \
+ LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \
+ configure ...
+```
+
+It is possible to compile FreeType in a different directory.
+Assuming the FreeType source files in directory `/src/freetype` a
+compilation in directory `foo` works as follows:
+
+```bash
+ cd foo
+ /src/freetype/configure [options]
+ make
+ make install
+```
+
+
+### 3.1 Interdependency with HarfBuzz
+
+Note that there is a chicken-and-egg problem currently since the
+HarfBuzz library (used by the auto-hinter to improve support of
+OpenType fonts) depends on FreeType, which can be solved as
+follows in case HarfBuzz is not yet installed on your system.
+
+1. Call FreeType's `configure` script with option
+ `--without-harfbuzz`, then compile and install FreeType.
+
+2. Compile and install HarfBuzz.
+
+3. Call FreeType's `configure` script without option
+ `--without-harfbuzz` (after executing `make distclean`), then
+ compile and install FreeType again.
