Dear All, Moderator from forum.qt.io recommended to ask the question here:
Gcc ABI was significantly changed between 4.x and 5.x. If you try to link application with third-party library that was compiled with an older version of GCC then you get linker errors about undefined references to symbols that involve types in the std::__cxx11 namespace. The problem is related to https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html
But the same Qt pre-build binary distribution from the official site for Linux links correctly with gcc 5.x and gcc 4.x.
How to get the same result with other 3rd-party libraries? How the problem of different gcc ABI is resolved? Is _GLIBCXX_USE_CXX11_ABI=0 defined for Qt pre-build version that is available to download?
Thanks, Alex
