Hi, I would like to compile digikam 4.4.0, but there is an compile error in libkface, always regarding OpenCV. So far I have tried these steps with no success. 1. compile digikam ~5.1.0 2. compile libkface versions 4.4.0 ~4.12.0(4/3) ~15.08.3(4/15.08) 16.04.3 3. change plasma from ~5.7.4 to 5.6.5 back and forth 4. compile opencv 2.4.12(0/2.4) ~2.4.12-r1(0/2.4) ~3.0.0(0/3.0) ~3.1.0-r4(0/3.1) 4. update all system, revdep-rebuild, etc... -- Found KDE 4.12 include dir: /usr/include -- Found KDE 4.12 library dir: /usr/lib64 -- Found the KDE4 kconfig_compiler preprocessor: /usr/bin/kconfig_compiler -- Found automoc4: /usr/bin/automoc4 -- First try at finding OpenCV...

May be it is duplicate bug to 591852?
Do you have a manual opencv install? It's finding stuff in /usr/local/share/OpenCV/.
Thank you for your quick response. I found there those files: ls -1 haarcascades lbpcascades OpenCVConfig.cmake OpenCVConfig-version.cmake OpenCV # cat OpenCVConfig-version.cmake set(OpenCV_VERSION 2.4.6.1) set(PACKAGE_VERSION ${OpenCV_VERSION}) set(PACKAGE_VERSION_EXACT False) set(PACKAGE_VERSION_COMPATIBLE False) if(PACKAGE_FIND_VERSION VERSION_EQUAL PACKAGE_VERSION) set(PACKAGE_VERSION_EXACT True) set(PACKAGE_VERSION_COMPATIBLE True) endif() if(PACKAGE_FIND_VERSION VERSION_LESS PACKAGE_VERSION) set(PACKAGE_VERSION_COMPATIBLE True) endif()
I would suggest to backup and remove these files. Local installations like this are known to interfere with finding libraries.
Thank you very much, it solved the problem. How I was supposed know this? Could I read it somewhere in the error log? Regards.

I just happened to notice the paths in the log (eg. OpenCV headers: /usr/local/include/opencv;/usr/local/include), and know from experience with prior bugs that this is a likely cause.
