ninja: build stopped: subcommand failed.
....
/usr/bin/clang -g -o test_executable test.c
runs without any issues.
I tried without this:
-DLIBCXXABI_USE_LLVM_UNWINDER=OFF
but then it fails because it's linking to llvm unwind which i'm no longer building because... I also tried with:
-DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;compiler-rt;libunwind" \
But that also fails...
