Description of problem: Unable to build Apache Mesos with clang on EL6. Version-Release number of selected component (if applicable): clang-3.4-10.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. ./bootstrap 2. 3.

Apache Mesos builds with clang on Fedora 20.
From looking at the code, this looks like it's an issue in the exception_ptr.h not having a #include of <typeinfo> even though it uses the class type_info. Just for completeness, 3.4.2 is in the testing repo for EPEL6 right now and you could see if using the newer version resolves the issue, but if not, then I think that this bug needs to flow upstream to either stdlibc++ or clang.
"Clang's C++11 mode can be used ... with gcc's libstdc++, but patches are needed to make libstdc++-4.4 work with Clang in C++11 mode." (http://clang.llvm.org/cxx_status.html, http://clang.llvm.org/libstdc++4.4-clang0x.patch)
The above patch is for libstdc++ and not llvm/clang, so it would need to be submitted to that package for it to be included in RHEL.
Yes, the above links are only meant as additional info. I doubt there is a chance to get this in, because it doesn't seem to affect the system compiler.
Seems fixed in 6.6: https://bugzilla.redhat.com/show_bug.cgi?id=1061435
