Hi,
It seems that i have the well know problem with instalation qt4.8
The latest MinGW version is too new as we've already known.
So i tried to install the library with the old MinGW version that i've got from here :
http://sourceforge.net/projects/ming...e%20gcc-4.4.0/

The file is gcc-full-4.4.0-mingw32-bin-2.tar.lzma

but after i unpack it to the c:\MinGW directory, i think there are missing headers, even the include directory is empty.

So what else should i install?
