GLIBCXX versions

Question

If I compile a C++ program on my machine, and run it on another one (with older software) I get: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9\' not found.

Answer 1

In my opinion, if your binaries don't use the new features of newer GLIBCXX version, then they won't be linked with that version. So your binaries was linked with GLBCXX 3.4.9, there must be at least one symbol exported from it, and there're no any symbols exported from version newer than 3.4.9.
