Just trying out clang++.  Doesn't seem to be useful on f17.  Just include <complex> gives:

Hi Neil,

This is a known problem -- upstream fixed it rather late in the 3.1 development series, so it's not straightforward to backport the fix to the 3.0 we ship in Fedora 17.

I'm working on packaging LLVM/Clang 3.1 for Rawhide -- will try and sort out some of the directory layout issues at the same time. I'll ask around on the mailing list if we can push this to the stable branches too, if the key packages depending on LLVM (e.g. mesa) builds fine with 3.1.

Comment 2 Andrea 2012-06-21 08:50:14 UTC
I get the same issue.
Seems that every C++ program using the STL cannot compile.

This makes clang for C++ totally useless.

can a user decide to move to clang 3.1, even if Fedora does not want to upgrade clang during a release?

On my machine llvm & clang do not trigger any extra dependency, so it should be pretty riskless.

Comment 3 Andrea 2012-06-21 09:08:53 UTC
OK, I should have checked more.

llvm-libs-3.0 is only required by


Would it make sense to take them both from Rawhide? Or I go in an endless loop?

Comment 4 Kevin Kofler 2012-07-11 15:57:59 UTC
I think this really needs to be fixed, either by backporting the fix(es) or by just upgrading LLVM.
