# Xash3D FWGS on `musl` Xash3D FWGS works on `musl` out of the box. However, the engine doesn't try to differentiate glibc and musl anymore. If you see error similar to: ``` Host_InitError: can't initialize cl_dlls/client.so: Error relocating valve/cl_dlls/client.so: __sprintf_chk: symbol not found ``` ... or you know that the game you're running is linked against glibc, you can try using `libgcompat`, like this: ``` $ LD_PRELOAD=/lib/libgcompat.so.0 ./xash3d ... ``` It will automatically add the missing symbols that glibc binaries usually need. In the future we might automatically link engine against `libgcompat` for better compatibility with prebuilt or closed-source games, if there will be any use for this.
