Normally I would know to use
pkg-config --libs opencv
as part of my linker command (ok, properties in NetBeans). However, I can't seem to get it to work.
The symptom of it not working is a laundry list of link-time errors that looks like:
/usr/local/include/opencv2/core/core_c.h:134: undefined reference to `cvFree_'
/usr/local/include/opencv2/core/core_c.h:142: undefined reference to `cvFree_'
build/Debug/GNU-Linux-x86/_ext/602031749/usingOpenCV.o: In function `cvGetRow':
/usr/local/include/opencv2/core/core_c.h:184: undefined reference to `cvGetRows'
build/Debug/GNU-Linux-x86/_ext/602031749/usingOpenCV.o: In function `cvGetCol':
/usr/local/include/opencv2/core/core_c.h:195: undefined reference to `cvGetCols'
From what I read the opencv.pc file produced when i built opencv following these instructions, is broken or non-standard.
- *Is this correct? Is there a fix/patch? With instructions on how to apply it? *
- Does anyone have an opencv.pc file that returns the usual -l nad -L type entries rather than the list of .so's.
- Are there other tags i should add to this question? I am not familiar enogh with opencv to know which to select for it.
Example:
$ pkg-config --libs opencv
/usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local
/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local
/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so
/usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so
/usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so
/usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so
/usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so
/usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so
I was really expecting something that looked like -L/usr/local/lib -lopencv-core ....
I tried coding the -l's by hand in my NetBeans linker command, but that fails also. :-(
-o ${CND_DISTDIR}/${CND_CONF}/${CND_PLATFORM}/autostart -L/opt/voyant/lib -L/usr/local/lib
