[Qgis-developer] Compilation qgis2.7.0 with VS2010 and Qt 5.3.2

[Matthias Kuhn]

Hi Anatoliy,

Does that mean that it worked fine before PR #1743?
In general Qt5 support is still pretty new and did not receive much
testing. I don't know how many people have run such a setup on Windows.
It requires to also link dependencies like qwt, qwtpolar and qscintilla
against Qt5.
That said, it is very welcome if people test and improve Qt5 support.
But if you want to stay out of the way of problems you are better off if
you stick to the well-tested Qt4.

Anyway, the problem you have here looks like a linker problem to the
MSVCRT, so Windows specific and not Qt5 specific. As I seldom use
Windows I can't offer more help than this hint, sorry.

Regards,
Matthias
