[ros-users] Bug in ROS Ubuntu package libopencv2.3-dev_2.3.1…

Hi list,

if I do

g++ -o myprog myprog.cpp `pkg-config --cflags --libs opencv-2.3.1`

I get

/usr/bin/ld: cannot find -l/usr/lib/libopencv_contrib.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_legacy.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_objdetect.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_calib3d.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_features2d.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_video.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_highgui.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_ml.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_imgproc.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_flann.so.2.3.1
/usr/bin/ld: cannot find -l/usr/lib/libopencv_core.so.2.3.1

In my opinion the problem lies in the pkg-config file opencv-2.3.1.pc,
which is fixed by the patch in the attachment.

Regards,
David
