gcompat alone provides only the ELF interpreter entry point (/lib64/ld-linux-x86-64.so.2).
It does NOT provide libpthread.so.0, libm.so.6, libdl.so.2, libc.so.6 stubs.
libnvidia-ml.so.590 has NEEDED: libpthread.so.0 etc. When nvidia-smi calls
dlopen("libnvidia-ml.so.1"), musl's linker fails to satisfy these deps
→ NVML_ERROR_LIBRARY_NOT_FOUND (exit 12), "couldn't find libnvidia-ml.so".
libc6-compat provides the missing stubs (libpthread.so.0, libm.so.6, libdl.so.2,
libc.so.6, librt.so.1) as musl redirects, enabling dlopen of glibc shared objects.
