[Development] Qt5 beta, MinGW: undefined reference to `WinMain at 16'

[casper.vandonderen at nokia.com]

Hi,

Which GCC is this (both for w32 and w64)? For KDE I tried to use 4.6.4 and we are having a lot of problems with that, so we are now waiting for a patched GCC 4.7.x

Does anyone care about mingw support?
It's an qt5 issue, or an mingw issue?
I don't sure anything, but it's real noise!
Because I can't corss build for Windows use Qt5 now.

I just create a bug report, and hope someone can take of.
It's only Qt5 issue, Qt4 works well!!

Yes, same problem happened when using qmake.
for qbs, I made a patch for link to static library, see: https://codereview.qt-project.org/#change,29232

Does the same problem happen if using qmake instead of qbs?
There is a qtmain.lib static library that should be added automatically to windows executables, which provides the WinMain entry point.
