I followed the guide here: https://wiki.allegro.cc/index.php?title=Building_with_msys2

I also read some threads in here on this forum, but the closest I am coming to succeding in compiling is this:

Mind@Lovelace MINGW64 ~/build_allegro_monolith
$ cmake -G"MSYS Makefiles" -DWANT_MONOLITH=on ../allegro5

-- Build files have been written to: C:/msys/msys64/home/Mind/build_allegro_monolith

followed by this when make && make install:

Hmm, for you non swedes, misslyckades = failed
receptet för målet = recipy for the target

Thankful for any advice. Managed to compile this in the past with msys2 but it was like a year ago and I can't remember exactly how I did it back then.

Yeah, looks like there was a bug added to the build system. I believe it will only affect that one example, so if you don't need examples, pass -DWANT_EXAMPLES=off to cmake.

It didn't affected me on the same plateform and compiler.

Actually yes, I take that back. I made an error with my paths, and after fixing it, it worked again. What changed recently is that the core library no longer links D3DX9, but loads the binary at runtime, so if there's any linking issue, it'll only happen when you build this example.

Check your CMakeCache.txt in the build directory and make sure it has this line in it:

D3DX9_LIBRARY:FILEPATH=F:/msys64/mingw64/x86_64-w64-mingw32/Lib/libd3dx9.a

What I used to compile this is actually this:

export DXSDK_DIR=/mingw64/x86_64-w64-mingw32
cmake .. -G"MSYS Makefiles"
make -j8

I do it that way because I actually have the real DirectX SDK installed, and CMake keeps trying to use it instead of the one shipped with msys...
