I compiled the gcc 4.4.0 release from source and upon trying execute a simple hello world program that uses std::thread I get the following error: ./t: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ./t) All non c++0x aspects of gcc/stdc++ seem to work fine. I'm sure I've likely done something silly when compiling/installing gcc... any ideas?
