Build Linux 64-bit and some bug

[johnsmith]

Hi GAMELASTER, I'd recommend installing your Qt build from the Qt-x64 project from sourceforge.net/projects/qtx64/files/qt-x64/

It's up to date and will give an x64 Qt built with MinGW-w64. The MinGW-w64 project's GCC compiler is also included in the installer versions (but not in the 7z). You'll want the same version of GCC in MinGW-w64 that was used to build Qt for building your own apps, so I'd recommend going with the installer.

You'll need to choose a build with the exception stack frame unwinding method you want. The question What is difference between sjlj vs dwarf vs seh? describes the differences between the types of exception handlers that are present in different builds of Qt. SJLJ was the only choice before GCC 4.8 was released, but later GCC versions support SEH. Either choice will work, though SEH is more efficient.
