Must be the version of clang or the std::map lib included by qt, which does or does not define something correctly with const and the compare operator. clang works fine for me : Code (text): Debian clang version 3.2-7ubuntu1 (tags/RELEASE_32/final) (based on LLVM 3.2) Target: x86_64-pc-linux-gnu Thread model: posix At least for the teambuilder (compile error on RelayStation!) I have ubuntu 13.04. Edit: I've tried something, maybe it will work? At least it can't hurt.
Yes, this helped. Looking at the first error message, no matching function for call to object of type 'const icompare, it should have been obvious what is the problem :)
