Re: Clang c++ include path

[David Truby <David.Truby@arm.com>]

Hi,

This patch doesn't work for me as it seems to have a similar issue
finding the libc++ headers.


I do have a fix for the libstdc++ header issue though, I'm just trying
to clean up the patch and then will send it to paches-guix. It involves
patching the source, so will trigger a rebuild of anything depending on
clang (however it doesn't touch llvm). I haven't yet worked out a way
of fixing libc++ but it should be fixable in a similar way.


I actually have two ways of fixing it though and am unsure which is
more appropriate. The non-controversial one is to just get the
libstdc++ header directory for the default gcc and patch clang to look
there. However, as an end user of the clang package I would rather have
a make-clang-toolchain procedure that takes a gcc-toolchain version and
gets the standard library from that. I've got implementations of both
of these, does anyone have an opinion which one would be preferred?
