You either link against the shared library or you use "QLibrary":http://developer.qt.nokia.com/doc/qt-4.8/qlibrary.html to load the library at runtime.

Hi,

As far as I know, you can use it by including it like -lpng -lbb2d -lcsi etc, here as an example I have libpng.so, libbb2d.so, libcsi.so etc..... Its similar to the way Lukas Geyer has mentioned I guess!

If your library is pure C so it is possible to use it like Lukas explained. But if your contain C++ symbols is not that simple. Take a look at "this post":http://stackoverflow.com/questions/8521929/linking-against-so-library-without-header-files-via-objdump

thanks all! I tried read and worked follow QLibrary but I still understand enough about that. And my .so file, which i have, is pure C but file .h attach with it have #include <jni.h> (a .h file in java) i try use it on Qt on Windows (not Linux)? Can be worked? Plz explain me clearly.

Thanks for all supports again!

l.v.p

If you right-click on your project name (in project browser) there is option Add Library. Then a window where you choose type of linking and library and then you have library in your project. Check it out.
