Minimal gcc version for 5.3 and gcc used with distributed libraries

[ycyclop]

I looked in the forums and found that the recommended minimum gcc version is 4.7.2 but I could not found any official recommendation .
In the Windows recommendation there is a section referring to MinGW under http://qt-project.org/doc/qt-5/windows-issues.html but there is nothing under http://qt-project.org/doc/qt-5/linux.html like you'd expect.

Is there also any information which gcc was used to build the linux distribution libraries?

Qt can be compiled with any compiler supporting C++98 standard. So GCC 4.3 should do it just fine (previous versions may also work well).
