Hi
Having installed the library I tried to run the demo
zafar@system:~/src/Xkin/demo/demo$ sudo ./demoposture -i ../tools/testposture -d ../img/
I got the error
OpenCV Error: Parsing error (../tools/testposture(0): Too long string or a last string w/o newline) in icvXMLSkipSpaces, file /build/buildd/opencv-2.3.1/modules/core/src/persistence.cpp, line 1750
terminate called after throwing an instance of 'cv::Exception'
what(): /build/buildd/opencv-2.3.1/modules/core/src/persistence.cpp:1750: error: (-212) ../tools/testposture(0): Too long string or a last string w/o newline in function icvXMLSkipSpaces
Does your library require OpenCV >=2.4?
