Mixing static and dynamic libraries using Qt Creator

[xsades]

I have a static Qt build. I am trying to use openCV shared libraries with statically linked Qt and standart c libraries. I couldn'yt figure how to do that.

Here is my .pro file10952


If i compile this code: 10953

resulting .exe works correctly without asking any .dlls.

But if i use openCV library and compile this code:

10954

resulting .exe asks for both "libopencv_core2410.dll" and other standart libraries like "libgcc_s_dw2-1.dll"

What i want is make it ask only for opencv shared libraries. Any help will be appreciated. Sorry for my bad English. :)

You can't do that unless you compile the c++ runtime from MinGW statically into the opencv dll. Which is probably out of scope of this forum.

Thanks! I've compiled opencv statically and problem was solved.

Hi, can you explain how you static compile opencv for qt. In cmake when i set BUILD_SHARED_LIBS=off i got this error Make Error at apps/haartraining/CMakeLists.txt:37 (add_library):
Target "opencv_haartraining_engine" links to itself.
And then in vs when i compile opencv i got lot of this errors:

Error 45 error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall QMutex::QMutex(enum QMutex::RecursionMode)" (__imp_??0QMutex@@QAE@W4RecursionMode@0@@Z) referenced in function "void __cdecl `dynamic initializer for 'mutexKey''(void)" (??__EmutexKey@@YAXXZ) C:\ocv\myocv\apps\annotation\opencv_highgui2411.li b(window_QT.obj) opencv_annotation
I use staticly compile Qt 5.4.1 with mingw32 and opencv 2.4.
Thanks for any help
