where/what are static plugins?

Jacek, you are asking a very good question about the compiler. The compiler says:

-LC:/Qt/4.3.3/plugins/imageformats/ -lqmng4 -lQtGui -ldgi32 -lcomdlg32 -loleaut32 -limm32 -lwinmm -lwinspool -lmsimg32 -lQtCore -lkernel32 -luser32 -lshell32 -luuid -lole32 -ladvapi32 -lws_32

but my working directory is Qt/static, not Qt/4.3.3. Seems like the system is confused about the folder where imageformat flugins are. What does that mean?

I just put the imageformat plugins in the folder that compiler wants. Now the error is:
"cannot find -lqjpeg4"

What does that mean?

It means that most likely you were using the wrong qmake.

Run:

make clean
C:\Qt\static\bin\qmake
make

Jacek, you are a genius! Thank you so much, your suggestion worked and now everything is perfect!

After two weeks of banging my head against the wall!
