Building Wine with MinGW cross-compilation

Building Wine with MinGW cross-compilation

Hello Guix, 

in recent versions Wine (Wine-Staging in our case) gained the ability to
build modules as PE files for better compatibility. I've been trying to
get this working and was wondering if someone more familiar with
cross-compilation knows what's going wrong with the compilation. 

First I tried adding mingw-w64 to the native-inputs. This results in a
configure error: "C compiler cannot create executables". See
wine-patch1.patch for the patch and wine-patch1-config.log for the
configuration log. 

I've had a little more success with adding MinGW triplets of cross-gcc
and cross-binutils to native-inputs. See wine-patch2.patch and
wine-patch2-config.log. 
The configure phase does work this time and MinGW cross-compilation
seems to be recognized. However during compiling eventually I get a
failure regarding #include_next and stdarg.h:

If I add cross-libc it just seems to add mingw-w64 again and I get the
same error about the C compiler not being able to create executables. 

Does anyone have any ideas on how to fix this?

Hi Rutger!

Did you ever figure out the mingw wine cross-compilation? I believe it has something to do with the CROSS_* env vars or search path order, becuase stdarg.h is definitely provided by mingw-w64.

Hi Carl, 

unfortunately I'm still stuck. The stdarg.h error only appears if I add
MinGW cross versions of gcc and binutils. If I add mingw-w64 instead of
those the build quits immediately upon the configure phase with an error
that the C compiler cannot create executables.
