Hello, There is an ABI breakage with OpenCV 2.2 update. Actually it is more a rename (1) , so as soon as your package rely on pkgconfig or opencv.cmake, thats should be silent. Here is a koji --scratch build for dist-rawhide http://koji.fedoraproject.org/koji/taskinfo?taskID=2704279 The packages is already imported into git and I will probably 'fedpkg build' later tonight. Here is the list of the affected packages: (I will handle frei0r-plugins that I own). # repoquery --whatrequires "libcv.so.2.1()(64bit)" fawkes-core-0:0.4-7.fc14.x86_64 fawkes-firevision-0:0.4-7.fc14.x86_64 frei0r-plugins-0:1.1.22-5.fc14.x86_64 frei0r-plugins-0:1.2.1-1.fc14.x86_64 kipi-plugins-0:1.4.0-1.fc14.x86_64 kipi-plugins-0:1.6.0-1.fc14.x86_64 mrpt-apps-0:0.9.0-0.5.fc14.x86_64 mrpt-base-0:0.9.0-0.5.fc14.x86_64 mrpt-gui-0:0.9.0-0.5.fc14.x86_64 mrpt-hmtslam-0:0.9.0-0.5.fc14.x86_64 mrpt-hwdrivers-0:0.9.0-0.5.fc14.x86_64 mrpt-maps-0:0.9.0-0.5.fc14.x86_64 mrpt-obs-0:0.9.0-0.5.fc14.x86_64 mrpt-opengl-0:0.9.0-0.5.fc14.x86_64 mrpt-reactivenav-0:0.9.0-0.5.fc14.x86_64 mrpt-slam-0:0.9.0-0.5.fc14.x86_64 mrpt-topography-0:0.9.0-0.5.fc14.x86_64 mrpt-vision-0:0.9.0-0.5.fc14.x86_64 opencv-devel-0:2.1.0-5.fc14.x86_64 opencv-python-0:2.1.0-5.fc14.x86_64 php-facedetect-0:1.0.0-6.fc14.x86_64 player-0:3.0.2-4.fc14.x86_64 (1)New SO follow this form: # rpm -q --provides opencv libopencv_calib3d.so.2.2()(64bit) libopencv_contrib.so.2.2()(64bit) libopencv_core.so.2.2()(64bit) libopencv_features2d.so.2.2()(64bit) libopencv_flann.so.2.2()(64bit) libopencv_gpu.so.2.2()(64bit) libopencv_highgui.so.2.2()(64bit) libopencv_imgproc.so.2.2()(64bit) libopencv_legacy.so.2.2()(64bit) libopencv_ml.so.2.2()(64bit) libopencv_objdetect.so.2.2()(64bit) libopencv_video.so.2.2()(64bit) -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
