Static build

[AndrzejB]

I have installed .lib and lib.a files, but CONFIG += static in pro not helps

What are you trying to achieve? Build a statically linked application? Build a static library? Link a static library? Use statically built Qt?

statically linked application

[dheerendra]

How are you trying to link ? Can you show the configuration ?

[sierdzio]

Yep, we'll need more info like @dheerendra suggested.

Other than that, I can recommend the very general instructions from Qt docs.
