[SOLVED] Help me with qtlockedfile_win.cpp

Hi,
I'm trying to build the opensource PokerTH game under win 8 with QT 5.2.1 mingw
and stucked on qtlockedfile_qin.cpp

screenshot with errors*

!http://ofc.kz/image/data/qtErrors.jpg(qtlockedfile_win.cpp errors)!

there is kind a syntax related errors, i tried to use other versions of qtlockedfile that i found around the web
but they were far more errors

i started building under linux, as instructions told but stucked at the very beginning of building process,
and got a lot of unfigurable errors ,
then i try qt-5.2.1 windows mingw edition and go much further than with linux qt.

Can somebody at least point me where to dig in,

Almax

after a while i solve that by adding some semicolons and inserting this -

#if QT_VERSION >= 0x050000
#define QT_WA(unicode, ansi) unicode
#endif

Hi and welcome to devnet,

You should consider going on the "bug report system":http://bugreports.qt-project.org to signal this, other users might get hit by it
