Building `gm2` on Windows

Steps :

We first check that the active gcc executable comes from the MinGW binary distribution. In our case we need to switch our default gcc as follows :

> where gcc
C:\opt\msys64\usr\bin\gcc.exe
 
> where /r c:\opt\mingw64 gcc
c:\opt\mingw64\mingw64\bin\gcc.exe
 
> set "PATH=c:\opt\mingw64\bin;%PATH%"
 
> where gcc
c:\opt\mingw64\bin\gcc.exe
C:\opt\msys64\usr\bin\gcc.exe

Note: In our case the locally installed MinGW binary distribution include a newer gcc version :

> C:\opt\msys64\usr\bin\gcc.exe --version | findstr /b gcc
gcc (GCC) 13.3.0
 
> c:\opt\mingw64\bin\gcc --version | findstr /b gcc
gcc (x86_64-win32-seh-rev0, Built by MinGW-Builds project) 14.1.0

We enter the GCC source directory (e.g. gcc\), start a Unix session with command sh and check the gcc version :

> C:\opt\msys64\usr\bin\sh.exe
$ pwd
/c/Users/michelou/workspace-perso/m2-examples/gcc
 
$ which gcc
/c/opt/mingw64/bin/gcc

We execute shell script contrib/download_prerequisites once to be sure we have the required packages :

 $ cd gcc-source
  
 $ ./contrib/download_prerequisites
 2023-11-12 11:46:32 URL:http://gcc.gnu.org/pub/gcc/infrastructure/gmp-6.2.1.tar.bz2 [2493916/2493916] -> "gmp-6.2.1.tar.bz2" [1]

 mpfr-4.1.0.tar.bz2: OK
 mpc-1.2.1.tar.gz: OK
 isl-0.24.tar.bz2: OK
 All prerequisites downloaded successfully.
  
 $ find . "*.tar.*"
./gettext-0.22.tar.gz
./gmp-6.2.1.tar.bz2
./isl-0.24.tar.bz2
./mpc-1.2.1.tar.gz
./mpfr-4.1.0.tar.bz2

Note: We further install the following MSYS2 packages which are also required to generate the GCC distribution (but are missing in our local MSYS2 installation).

automake (/usr/bin/aclocal, /usr/bin/automake)

msys/texinfo (/usr/bin/makeinfo)
> where automake make makeinfo
c:\opt\msys64\usr\bin\automake.exe
c:\opt\msys64\usr\bin\make.exe
c:\opt\msys64\usr\bin\makeinfo.exe

Build configuration

By default the configure script doesn't include the Modula-2 frontend in the generated build file Makefile, e.g.

   $ ./configure \
   --host=x86_64-pc-mingw32 \
   --prefix=/c/opt/gcc-13.2.0
   checking build system type... x86_64-pc-msys
   checking host system type... x86_64-pc-mingw32
   checking target system type... x86_64-pc-mingw32
   [...]
   checking whether g++ supports C++11 features by default... yes
   checking whether g++ supports C++11 features by default... yes
   checking for objdir... .libs
   configure: WARNING: using in-tree isl, disabling version check
   The following languages will be built: c,c++,fortran,lto,objc
   [...]

We have to specify option --enable-languages in order add value m2 to the list of supported languages :

   $ mkdir /c/temp/gcc
    
   $ ./configure \
   --host=x86_64-pc-mingw32 \
   --prefix=/c/temp/gcc \
   --enable-languages=c,c++,lto,m2

Build execution

Note: GNU make version 3.80 or newer is required.
```
$ make
```

Build steps

$ cd gcc-source\build
$ make

Step 1 : `libiberty`

$ cd libiberty
$ ../../libiberty/configure --host=x86_64-pc-mingw32 --prefix=/c/temp/gcc --enable-languages=c,c++,lto,m2
$  make

Step 2 : `fixincludes`

$ cd fixincludes
$ ../../fixincludes/configure --host=x86_64-pc-mingw32 --prefix=/c/temp/gcc --enable-languages=c,c++,lto,m2
$ make

Note: Makefile on line 30 old : CFLAGS = -g -O2 new : CFLAGS = -g -O2 -save-temps=obj

Step 3 : `gettext`

$ cd gettext
$ ../../gettext/configure --host=x86_64-pc-mingw32 --prefix=/c/temp/gcc --enable-languages=c,c++,lto,m2
$ make

[2] Source file modifications ↩

We add the following code to the C source file m2-examples\gcc\gcc-source\libiberty\pex-win32.c as follows :

/* See https://gcc.gnu.org/pipermail/gcc-cvs/2020-December/339598.html
*/
#ifndef_O_BINARY
#  define _O_BINARY O_BINARY
#  define _O_CREAT O_CREAT
#  define _O_NOINHERIT O_CLOEXEC
#  define _O_RDONLY O_RDONLY
#  define _O_TEXT O_TEXT
#  define _O_TRUNC O_TRUNC
#  define _O_WRONLY O_WRONLY
#
#  define _close close
#  define _dup dup
#  define _open open
#  define _read read
#endif
 
#ifndef _S_IREAD
#  define _S_IREAD S_IREAD
#  define _S_IWRITE S_IWRITE
#endif

We modify file m2-examples\gcc\Makefile (lines 396-297) :

 #AS = x86_64-pc-mingw32-as
 AS = /usr/x86_64-w64-pc-msys/bin/as
 #AR = x86_64-pc-mingw32-ar
 AR = /usr/x86_64-w64-pc-msys/bin/ar

We modify file m2-examples\gcc\gcc-source\gcc\config\i386\host-mingw32.cc as follows (lines 29ff); our modification is based on file m2-examples\gcc\gcc-source\gcc\ada\mingw32.h (lines 50-55) :

#if defined (__CYGWIN__) && !defined (__CYGWIN32__) && !defined (IN_RTS)
/* Note: windows.h on cygwin-64 includes x86intrin.h which uses malloc.
   That fails to compile, if malloc is poisoned, i.e. if !IN_RTS.  */
#define _X86INTRIN_H_INCLUDED
#define _EMMINTRIN_H_INCLUDED
#endif
#define WIN32_LEAN_AND_MEAN  /* Not so important if we have windows.h.gch.  */
#include <windows.h>
#include <stdlib.h>
#include <io.h>
