Compiling on MacOS

[Saul Tobin]

Hi all,

I'm trying to figure out how to compile Lilypond on MacOS (Sequoia, Intel
Mac, Homebrew) so I can do things when I'm away from my desktop.

So far I've succeeded in compiling Lilypond itself, but I'm completely
stumped on why I can't build regtests. The error I get is:

Making input/regression/out-test/collated-files.list < 1941 files
Making input/regression/out-test/collated-files.tely
Traceback (most recent call last):
  File
"/Users/<myusername>/<path>/<to>/lilypond/scripts/build/lys-to-tely.py",
line 209, in <module>
    files = open(input_filename, encoding='utf-8').read().split()
            ~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory:
'out-test/collated-files.list'
make[3]: *** [out-test/collated-files.tely] Error 1
make[2]: *** [lysdoc-test] Error 2
make[1]: *** [test] Error 2
make: *** [test-baseline-pre] Error 2

As far as I can tell there's no log file created by either lys-to-tely.py
or by the preceding step creating collated-files.list.

I more or less followed the path described here
https://danieljohnson.name/blog/installing-lilypond-on-macos, with a few
differences:

   1. I used the latest Flex from Homebrew (2.6.4), and except for some
   probably harmless compiler warnings it seems to work fine.
   2. I installed all fonts listed in the contributor docs at the MacOS
   level. I tried passing --with-fonts-dir to configure as recommended in the
   docs, but the flag wasn't recognized. I'm guessing this might be something
   that changed with the pango overhaul, but didn't get updated in the
   contributor docs?
   3. Installing dblatex was a nightmare. It isn't packaged for Homebrew
   except in some very out of date third party taps and by default Homebrew
   blocks pip from being used without a virtual environment. Worse, dblatex is
   straight up incompatible with both Python 3.13 (which is the system Python3
   default) and with Python setuptools >65. I wasted a lot of time trying to
   install it with pip, as even when it worked it failed to properly install
   the executable script. I was finally able to install dblatex 0.3.11 from
   source using Python 3.10, after manually editing the version string to work
   with setuptools and the shell script to explicitly use python3.10. Honestly
   I'm mildly surprised this hasn't caused issues on other platforms. The
   dblatex project seems to be on life support.
   4. I used the following:

   
PATH="/usr/local/opt/gettext/bin:/usr/local/opt/flex/bin:/usr/local/opt/bison/bin:$PATH"
   CC=gcc-14 CPP=cpp-14 CXX=g++-14 LDFLAGS="-L/usr/local/opt/flex/lib
   -L/usr/local/opt/bison/lib -L/usr/local/opt/gettext/lib"
   CPPFLAGS="-I/usr/local/opt/flex/include -I/usr/local/opt/bison/include
   -I/usr/local/opt/gettext/include" ../autogen.sh --disable-optimising

   Configure completes with no warnings. I used the same environment
   variables for invoking make and make test-baseline.

Any ideas?
