Expected Behavior

Expected sunshine master to compile.

Additional Context

I build master regularly, this is a recently intruduced issue. I suspect the interface of libnotify changed.

Try gcc 14 or lower, you need a lower version for nvidia/cuda support as well.

@rubin55 if you're using our linux build script this should be resolved by #3846

This issue should probably remain open though until Sunshine is compatible with gcc 15.

Just to confirm; I was able to build tagged version v2025.122.141614 perfectly fine on Fedora 42, using GCC-14:

cmake -DCMAKE_C_COMPILER=gcc-14 -DCMAKE_CXX_COMPILER=g++-14 -DCMAKE_ASM_COMPILER=gcc-14 -DBUILD_DOCS=off -B build -G Ninja -S .

I did have to disable the building of the documentation as per #3852 to get it to succeed.

[rubin55]

Can confirm that building with gcc 14.x works as expected.
