Linking issue on HXCPP_MINGW under MSYS2

[ovidiugabriel]

Hello,

I am trying to build an older project that once built successfully on hxcpp. I have "skipping incompatible" error message for every possible lib linked in the project.

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: 
skipping incompatible 
C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../libws2_32.a 
when searching for -lws2_32

I also tried to use -D HXCPP_M32 but it did't fixed the issue.

cygpath "C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../libkernel32.a"

# will resolve to
/mingw64/lib/libkernel32.a

# This path is pointing to the same libkernel32.a as we expect (c:\msys64\mingw64\lib\libkernel32.a)

$ md5sum.exe /c/msys64/mingw64/lib/libkernel32.a
f180b3cfae56f5db30c6e3a6b1be9d77 */c/msys64/mingw64/lib/libkernel32.a

$ md5sum.exe /mingw64/lib/libkernel32.a

Haxelib version

$ haxelib version
4.1.0

Do you have any idea how this can be fixed? Am I missing something?

I also tried to use -D HXCPP_M32 but it did't fixed the issue.

You could try running with -D HXCPP_M64, but you'll have to use the git version of hxcpp:

haxelib git hxcpp https://github.com/HaxeFoundation/hxcpp

Thanks @tobil4sk . It worked. I can draw the following conclusions:

1) the default of hxcpp is on 32-bits, that's why specifying -D HXCPP_M32 had no effect 2) -D HXCPP_M64 is not supported in the release distribution 3) Of course, it seems I don't have 32-bits support configured in MinGW

If I remember correctly I have used -D HXCPP_M64 in the past with the release version of hxcpp and it worked, or maybe I'm wrong.
