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

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':

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.)
