As of version 2.0.8, it is possible to build klibc with Clang on at least some architectures. I don't what is the recommended way to build Debian packages with a non-default compiler, so I haven't tested whether that will now work. If you still care about this, and changes are needed in the Debian package, I am open to considering a patch.

Joseph Lee dixit: >I was trying to rebuild klibc with clang, not use it as libc. It failed Yes, and exactly that is (probably; not speaking for upstream, just from what I learned using and hacking and fixing it) not possible, and it’s not unreasonable to disallow it. bye, //mirabilos -- exceptions: a truly awful implementation of quite a nice idea. just about the worst way you could do something like that, afaic. it's like anti-design. that too… may I quote you on that? sure, tho i doubt anyone will listen ;) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

Hello, I was trying to rebuild klibc with clang, not use it as libc. It failed because clang can not find some header files when building. I tried to fix this by add something in makefile. And because of libklibc is needed by Debian to boot, I need to rebuild it to produce a bootable Debian.

Joseph Lee dixit: >Using the rebuilding infrastructure, your package failed to build with >clang instead of gcc. I think this is by design (upstream); klibc is sorta an embedded C library and for example does not honour the standard ELF i386 psABI for better performance and code size. bye, //mirabilos -- exceptions: a truly awful implementation of quite a nice idea. just about the worst way you could do something like that, afaic. it's like anti-design. that too… may I quote you on that? sure, tho i doubt anyone will listen ;) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
