These tests are all nolibc specific and so don't reference the system headers, the whole point is to not use a real libc. > What do I have to do to cross-compile these selftests? > I get various compiler errors. Any specific errors? It's just a standard selftest build, eg: make -C tools/testing/selftests LLVM=1 ARCH=arm64 TARGETS=arm64 Unless you've got very current userspace headers you'll probably need a headers_install too (that's generally needed for the selftests).
