[libc/libc++] Provide distribution archive for libc or fix libc++ to build without libc

[moubctez]

I am trying to package LLVM components for PkgSrc, and as for v20 libc++ fails to build with

fatal error: 'shared/fp_bits.h' file not found

It requires libc to build correctly, but that isn't packaged for GitHub releases.

Would it be possible to provide an archive for libc, or maybe make libc++ not to require these includes?

Thanks :)

libc++ is not going back to building without libc. Project hand in hand makes way more sense than reimplementing routines between the two projects.

I also don't think building outside of the monorepo is supported (hence this issue), although @ldionne would know. You probably just want to clone the monorepo and then only build libcxx.

Short answer, we're not planning to support this use case. We recommend building within the monorepo
