[BOX64] RPI5ARM: Failing to compile test_interpreter - stops the build in full

[IngwiePhoenix]

Hello!

I wanted to do a little experiment with the recently announced to be in preview Action1 Linux Agent - and, as a little "yolo idea", I wanted to see if I could get the agent to run under box64 on Linux. Why? ... Because I can? ;)

So I attempted to compile box64 with the following flags: cmake -G Ninja .. -DBOX32=ON -DBOX32_BINFMT=ON -DARM_DYNAREC=ON -D CMAKE_BUILD_TYPE=RelWithDebInfo -DRPI5ARM64=1 -DUSE_CCACHE=1 -DWITH_MOLD=1

Output:

OS: Alpine 3.23.1, Raspberry Pi 5.

Did I miss an option perhaps?

Thanks and kind regards!

Are you using Clang? isnanf should be defined on linux on GCC, but might be missing with CLang. os.h is supposed to define it if needed (so if __clang__ is defined)
