We need a suitable backtrace to fix the problem... Look here for details ; http://techbase.kde.org/Development/Tutorials/Debugging/Debugging_on_MS_Windows Gilles Caulier New pre-version of digiKam 4.2.0 windows installer is available here. https://drive.google.com/file/d/0B7yq-xFihT0_TTZTaXlUaExlaWs/edit?usp=sharing I recently released 4.1.0 installer which is available in offcial KDE download repository, but this version crash immediately when face detection is started. Crash appear when loading haar cascade XML files. There is no reason for that... The crash is inside core of OpenCV. This is not a problem relevant of digiKam. I'm sure, i found partially why : Originally, OpenCV have been compiled using minimal options enabled, to optimize install. This is the case of 4.1.0 where OpenCV 2.4.9 is installed as shared lib. Trying to find the problem using small libkface tests program, i finally tried to recompile and install whole OpenCV with all options enabled. And all work fine... I also check if face tagging crash digiKam. It don't... So to conclude : OpenCV is a big mess puzzle, providing around 30 optional features. Playing with this options as side effect due to internal dependencies. OpenCV is really weird here. For me this problem is an important UPSTREAM dysfunction which must be reported to OpenCV team. I don't know about Linux and OSX, but there is a big chance that similar problem will appear if OpenCV compilation options are enabled or disabled... digiKam 4.2.0 running Face Detection under Windows 7 : https://www.flickr.com/photos/digikam/14402474860/sizes/o/ So to all packagers, please take a care about OpenCV packages. Thanks in advance. Gilles Caulier |
