OpenCv troubles

Question

Hello, I'm trying to build the "tum_ardrone" package. I get the following error: /usr/bin/ld: skipping incompatible /usr/local/lib/libopencv_ml.so when searching for -lopencv_ml /usr/bin/ld: cannot find -lopencv_ml /usr/bin/ld: skipping incompatible /opt/ros/fuerte/lib/libopencv_nonfree.so when searching for -lopencv_nonfree /usr/bin/ld: skipping incompatible /usr/local/lib/libopencv_nonfree.so when searching for -lopencv_nonfree /usr/bin/ld: cannot find -lopencv_nonfree /usr/bin/ld: skipping incompatible /opt/ros/fuerte/lib/libopencv_objdetect.so when searching for -lopencv_objdetect /usr/bin/ld: skipping incompatible /usr/local/lib/libopencv_objdetect.so when searching for -lopencv_objdetect /usr/bin/ld: cannot find -lopencv_objdetect /usr/bin/ld: skipping incompatible /opt/ros/fuerte/lib/libopencv_photo.so when searching for -lopencv_photo /usr/bin/ld: skipping incompatible /usr/local/lib/libopencv_photo.so when searching for -lopencv_photo /usr/bin/ld: cannot find -lopencv_photo /usr/bin/ld: skipping incompatible /opt/ros/fuerte/lib/libopencv_stitching.so when searching for -lopencv_stitching /usr/bin/ld: skipping incompatible /usr/local/lib/libopencv_stitching.so when searching for -lopencv_stitching /usr/bin/ld: cannot find -lopencv_stitching /usr/bin/ld: skipping incompatible /opt/ros/fuerte/lib/libopencv_ts.so when searching for -lopencv_ts /usr/bin/ld: skipping incompatible /usr/local/lib/libopencv_ts.so when searching for -lopencv_ts /usr/bin/ld: cannot find -lopencv_ts /usr/bin/ld: skipping incompatible /opt/ros/fuerte/lib/libopencv_video.so when searching for -lopencv_video

...and so on.

I have installed opencv following the raccomandations on the official page. (I have installed it in a directory in my ~, maybe it's the reason it does not work).

Thanks for any help!

Answer 1

Is that an error you get using catkin_make? In your CmakeLists.txt are you using a cmake find module for openCV? As in:

find_package(OpenCV REQUIRED)

Then later

target_link_libraries(your_executable_name ${OpenCV_LIBS} ${catkin_LIBRARIES})

I've had to do that when working with the ARDrone.
