Why is xmake unable to find a library it just built?

As you can see, the library seems to have built and installed correctly, yet xmake is unable to find it...What could be causing this?

[star-hengxing]

It seems that cmake can't find the msvc environment variables then fallback to mingw. My guess is that your configuration is --plat=windows, so xmake can't detect the .lib file and report the error.

[smac89]

I'm just re-reading your comment, and I think you may not be following the output correctly. The platform is windows. I didn't set that myself. However, the build produces a .a file as you can see from the output:

[7/10] Linking C static library libexpat.a

My question is, why is this the case?

[star-hengxing]

My question is, why is this the case?

Already said.

It seems that cmake can't find the msvc environment variables then fallback to mingw.

And your log:

-- Check for working C compiler: D:/a/_temp/w64devkit/bin/gcc.exe - skipped

Github ci does't' provide a w64devkit toolchain. So I'm not sure how your local ci environment is configured. You can provide full log with xmake f -c -vD

[smac89]

The command I used was:

xmake config -vD --clean --arch=x64 --mode=release --yes

I also set the following environment variables:

CMAKE_GENERATOR=Ninja
CC=gcc
CXX=g++

I also switched the GCC compiler I was using to the winlibs version. The version I installed is:

gcc.exe (MinGW-W64 x86_64-msvcrt-win32-seh, built by Brecht Sanders, r1) 14.2.0

CMAKE_GENERATOR=Ninja
CC=gcc
CXX=g++

Why? If you want to use mingw toolchain, please use xmake f -c -p mingw.
Also use the package.cmake_generator.ninja policy to force xrepo to use ninja to build the package.
reference:

• https://github.com/xmake-io/xmake-repo/blob/dev/.github/workflows/windows.yml
• https://github.com/xmake-io/xmake-repo/blob/dev/.github/workflows/mingw_msys2.yml

The windows platform is bound to msvc by default. If you use package, it cannot support all toolchains, and currently only supports msvc/clang-cl. If you want to use gcc, then please explicitly specify mingw or cross platform. And use --toolchain=gcc to switch the toolchain completely, instead of just setting CC/CXX

xmake f -p mingw

mingw will use gcc by default
