Hi,

I would like to generate a d compiler targeting mingw-w64 using the msys2 build system.
So I have installed msys2 (posix emulation like cygwin) as shown here: http://msys2.github.io/ and I have installed necessary packages:

$ pacman -S base-devel
$ pacman -S mingw-w64-x86_64-toolchain

optionally you can also installed  mingw-w64-i686-toolchain if you want to build mingw32 packages but for now I am only interested in mingw64 (64 bits).

Then I have forked MINGW-packages repository (https://github.com/vrichomme/MINGW-packages) to make my experiments.

$ git clone https://github.com/vrichomme/MINGW-packages.git
$ cd MINGW-packages/mingw-w64-gcc

Inside mingw-w64-gcc I have used the 4 patches and renamed them to be more compliant with msys2 build system:

gdc-patch-gcc-5.patch
gdc-patch-toplev-5.patch
gdc-patch-versym-cpu-5.patch
gdc-patch-versym-os-5.patch

Then we are ready to start compilation:

$ MINGW_INSTALLS=mingw64 makepkg-mingw -sLf
...

 alias gthread_key_t   = pthread_key_t;
 ^
...

I am quite new to D language but I can see that posix.d imports core.sys.posix.pthread and I thought that on Windows Version(Posix) is not defined so how can it compile ?
Do I need to add a -DPosix or something like that ?
Do I need to add a Version(Mingw64) inside core.sys.posix.pthread ?

Thanks

Do you use winpthreads?
It seems the thread model is 'wrong':
https://github.com/D-Programming-GDC/GDC/blob/master/libphobos/configure.ac#L299

Please post the output of /home/19013692/MINGW-packages/mingw-w64-gcc/src/build-x86_64-w64-mingw32/./gcc/gdc -v


(I guess threadmodel is posix for winpthreads. But druntime doesn't really understand winpthreads. We'd have to modify core/sys/posix/pthread.d and adjust the version(Posix) block. But it's hard to estimate how many headers we need to change to support this.)

I tried to add a version(MinGW) inside core.sys.posix.sys.types to just declare pthread_key_t but it didn't work because I still have exactly the same error.
So am I supposed to do ?

Porting druntime to use the posix thread model for MinGW could be quite some work.

A simpler option is to simply build with the win32 thread model. Try to configure gcc with --enable-threads=win32

I tried with win32 and compilation stopped but don't know why:

When lookint a bit more to log file I think I found the reason:

I saw a patch talking about that https://github.com/venix1/MinGW-GDC/blob/master/patches/gcc/0001-Remove-fPIC-for-MinGW.patch so I am going to apply it and start again.

Ok I was able to generate a gdc compiler(x64) so now I need to test it and I will keep you informed.

It doesn't work...
$ gdc main.d
gdc.exe: error: CreateProcess: No such file or directory

Maybe it has something to do with missing files or something like that because when I run the gdc binary from the output folder (and before being packaged) I don'' have this error but on the other hand nothing happens:

$ export PATH=~/MINGW-packages/mingw-w64-gcc/src/mingw64/bin:$PATH
$ cd "C:\Developer\cygwin64\home\Vincent\projects\dlang\BonjourProvider\src"
$ gdc main.d -o toto.exe
$ ls toto.exe
ls: cannot access toto.Exe: No such file or directory

ok so end of story I am going back to c++, I already lost too much time with this.
