Hi Erik,

Unfortunatly Visual Studio is not an option for me.

I didn't find this page but as I understand it helps to install python libs
(extensions) with mingw. What I try to do is build python from src to get
an appropriate static library.
I can link it with my Qt toolchain (Mingw 4.6.3) and it compiles without
error, but it fails to run.
I double check it. All of my libs and tools are 32-bit.

Thank you very much for your help.

Regards,
Miklós
