Qt Opencv Integration

koahnig

You have no problem. This is showing only the error code on exit of your program. 0 is considered as no error.

but my program must show me a window and the picture on it what happens to them ?

koahnig

Oh, sorry, I have misinterpret your issue then.

pumper

now do you know whats the problem ?
I changed the pro file like this and same result nothing changed.
@
TEMPLATE = app
CONFIG += console
CONFIG -= qt

SOURCES += main.cpp

INCLUDEPATH += C:\opencv\build\include
INCLUDEPATH += "C:\opencv\modules\core\include"
"C:\opencv\modules\highgui\include"
BASE_PATH = c:/opencv/build/x86/mingw
CONFIG(release,debug|release)
{
win32: LIBS += -L$$BASE_PATH/lib/ -llibopencv_calib3d231
-llibopencv_contrib231
-llibopencv_core231
-llibopencv_features2d231
-llibopencv_flann231
-llibopencv_gpu231
-llibopencv_highgui231
-llibopencv_imgproc231
-llibopencv_legacy231
-llibopencv_ml231
-llibopencv_objdetect231
-llibopencv_video231
}
CONFIG(debug,debug|release)
{
win32: LIBS += -L$$BASE_PATH/lib/ -llibopencv_calib3d231
-llibopencv_contrib231

@cvWaitKey(0);@

edit: and maybe also without CONFIG += console

pumper

I tried these before nothing changed with these

pumper

one point may be help.
when i try to debug program i get this error box :

@
During the startup program exited with code 0xc0000005
@

@
the gdb process exited unexpectedly (code 0)

but when i put it on mingw build every thing is like what i said before.

pumper

Do you have the Dll's in path?

pumper

I copied dll's to the directory of EXE file and system32

pumper

I did it.
finally I've downloaded mingw32 and cmake and rebuild opencv from source with qt support and it worked like a charm.

gautham

i used the above include path files in qt but i am getting some errors like cannot open the library file calib3d231.

moondark

hello,

I have met the same problem, have u solved it?

I have tried again and again, but it didn't work

However, I have successed once, when I did something and restarted qt creator, but since I rewrite the .pro, it crashed. Except this, all are the same with you.
