Hi all,

I want to include OpenCV 2.2 library into my cascades project. I included following piece of code in .pro file:

LIBS += D:/OpenCV2.2/lib/*

INCLUDEPATH += ../src
INCLUDEPATH += D:/OpenCV2.2/include
INCLUDEPATH += D:/OpenCV2.2/include/opencv

When I build the project it doesn't produce any error. But when I try to include classes in the project it produces error:

#include <opencv/cv.h>
#include <opencv/cxcore.h>
#include <opencv/highgui.h>

Any kind of help will be highly appreciated.

Regards,

Nishant Shah

As I see you need to do following steps:

1) add to your *.pro file relative path to libs after "-L", extract shared lib names from files names (for example, libPocoFoundation.so.15 becomes PocoFoundation) and add after "-l" 

2) add relative path to includes

3) you can also try absolute path )

LIBS += -L../../POCO/lib -lPocoFoundation -lPocoNet -lPocoUtil -lPocoXML
INCLUDEPATH += ../../POCO/include

3) put your shared libs to some dir in assets and update LD_LIBRARY_PATH in bar-descriptor.xml (I create dir "lib" in assets dir)

was <env var="LD_LIBRARY_PATH" value="app/native/lib:/usr/lib/qt4/lib"/>

now <env var="LD_LIBRARY_PATH" value="app/native/assets/lib:app/native/lib:/usr/lib/qt4/lib"/>
