CMake still wont compile.
Will try building it under chroot.

Nope. Stage 1 clang has "no C++11 support"

As of commit 1d4aefb , CMake can bootstrap and configure but fails to build:

Looks like C Library implementation [by musl] has nullptr_t defined. Forced the libc++ headers to use musl's stddef.h in place of libc++'s cstddef:

Each time i modify a libc++ header, cmake builds further.... modified these libc++ headers as well:
I'll just use a link to replace cstddef with stddef.h
/cgnutools/include/x86_64-pc-linux-musl/c++/v1/__type_traits/is_array.h
/cgnutools/include/x86_64-pc-linux-musl/c++/v1/__type_traits/remove_extent.h
/cgnutools/include/x86_64-pc-linux-musl/c++/v1/__type_traits/is_member_function_pointer.h
from cmlfs.

Number of headers to modify continues to grow... Perhaps, use a link to replace cstddef with musl's stddef.h ?
ln -sv ../../../stddef.h /cgnutools/include/x86_64-pc-linux-musl/c++/v1/cstddef

Looks like a libc++ header needs musl's stddef.h added:
/cgnutools/include/x86_64-pc-linux-musl/c++/v1/__type_traits/is_fundamental.h
from cmlfs.

Modified header to use libc++'s cstddef? Since I renamed the real libc++ header as cstddef.orig then made a link of cstddef to point to musl's stddef.h, I added #include <cstddef.orig> to the following libc++ header:
/cgnutools/include/x86_64-pc-linux-musl/c++/v1/__type_traits/is_null_pointer.h
from cmlfs.

No. Problem just got re-routed:

So CMake wont cross compile. BUT compiles fine under chroot!
from cmlfs.
