Patches to compile CC++ 2 for Win32 with GCC using Mingw32

[Federico Montesino Pouzols]

        Hi all,

        I have been trying to compile cc++ 2 with GNU GCC as cross
compiler for Win32 (using Mingw on Debian). At first, I used the
Makefile.gcc in the win32 directory. I have found three errors while
compiling...


Error 1)
********

socket.cpp:

i586-mingw32msvc-c++ -c -I. -I../include -DHAVE_LIBXML
-I/usr/i586-mingw32msvc/include/libxml -DHAVE_CONFIG_H -D_GNU_SOURCE
-include ../win32/cc++/config.h -g -O2 -mthreads -o
../win32/../win32/socket.o ../src/socket.cpp
../src/socket.cpp: In function `SOCKET ost::dupSocket(unsigned int,
ost::Socket::State)':

was declared `extern' and later `static'
../include/cc++/socket.h:573: previous declaration of
`ost::dupSocket(unsigned int, ost::Socket::State)'
make: *** [../win32/socket.o] Error 1


        A patch for this is attached (patch-ccpp2-mingw-socket).



Error 2)

url.cpp:

        A patch for this is attached (patch-ccpp2-mingw-url).


Error 3)

then, linking:

make: *** [ccgnu2.dll] Error 1


        Which can be solved linking ws2_32 (an updated Makefile.gcc is
attached).

        With this, a static library and a dll for Win32 can be build
with a GNU environment.


        There is a second way to get it. There is a free awk script
(dsw2mak.awk) at
http://mefriss1.swan.ac.uk/~jfonseca/gnu-win32/software/msds/index.html,
by José Fonseca, that given a MSVC .dsp produces a makefile for
mingw32. This has the advantage that the mingw makefile can be
automatically updated from the new .dsps.

        I have got a CCXX.mak from the current CCXX.dsp and tweaked it
a bit so that CCXX.dll can be built (only uppercase/lowercase in the
first letter of some names of files). It is attached.


        There is also a third way to get it... building the library
with the GNU GCC and autotools environment using the cross compiler
based on Mingw32 (a typical configure and make). This method fails
with cc++ 2. I have tested the same cross compiler environment with
other libraries and apps and it works smoothly. However, with cc++ the
top level makefile does not recurse into the src directory and the
Makefile in src seems not to work. Grepping into the autoconf macros
it seems that some work has been done to detect Mingw32 environments,
and in fact it is correctly detected by configure.

        It does not work however. It seems that some autoconf macro
does not work well in this environment. Has anyone tested a
configuration like this or has any clue?
