Description of problem: When compiling a program using gcc34, errors of this kind appear at the end : /usr/lib64/libtag.so: undefined reference to `std::basic_ostream<char, std::char_traits<char>>& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, long)@GLIBCXX_3.4.9' It seems to be an incompatibility between the compilator given by "compat-gcc-34" and the libraries given by "compat-libstdc++-33" Version-Release number of selected component (if applicable): How reproducible: Try to compile and link a program with gcc34 Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

gcc34 doesn't ever use compat-libstdc++-33, that makes no sense at all. From the above I'm just guessing you are linking against C++ libraries that were compiled/linked with g++ rather than g++34, in that case obviously the link phase has to be done using g++ rather than g++34, because you can't limit to the subset of libstdc++ exported functions that were provided by 3.4.x.
