There has been no ABI compatibility affecting Qt. What you're seeing is not an ABI issue, it's the fact that you cannot compile with a version X of a library and run with version Y where Y < X. The libraries will have symbols that get used by their new headers and that weren't present in the old libraries. This applies to Qt as well as the C++ and C standard libraries. And all other libraries Qt uses. Assume ALL the libraries you need have such changes. > Looking to see if anyone else has done this recently? Which libraries do > I have to bring along?

Solution: install 14.04 in a chroot and build in there. > I tried compiling QT with C++11 standard, but, it will no longer compile > with that standard.
