Created attachment 136457 [details] Pictures of what to see when starts up first time after install SUMMARY Installing any digikam 7.2* version crashes at first start after install in Win7 64bit while starting main view. digikam 7.1 is working ok. I tried it since weeks to get 7.2 runningand failed. STEPS TO REPRODUCE 1. Install digiKam-7.2.0-20210306T200522-Win64-debug.exe 2. Start digikam 3. It crashes, see the picture in attachement OBSERVED RESULT It chrashes at startup EXPECTED RESULT It should start up fine SOFTWARE/OS VERSIONS Windows: 7 64 bit macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
We need the DebugView log from the start, as described here: https://www.digikam.org/contribute/ Don't forget to set the environment variable. I test digiKam-7.2.0 weekly on a Windows7 machine with no problems. Any weird anti-virus software installed? Maik

Delete the folder "C:/Users/jever.LOKAL/AppData/Roaming/digikam/facesengine". The files will be downloaded again automatically. Maik
Created attachment 136463 [details] Log after deleting the facesengine folder
Thx, after deleting the folder "C:/Users/jever.LOKAL/AppData/Roaming/digikam/facesengine" it downloaded the files while first start up. Then I end digikam as it said and started it a short time later again. It crashed again in the same manner as before.
Ok, when downloading the files, the digiKam GUI starts. So it is definitely related to the loading of the model data into OpenCV. Can you create and post the SHA256 checksums of the individual files in the "Roaming\digikam\facesengine" folder? Maik
Created attachment 136464 [details] facesengine folder individual files sha256 checksums The SHA256 checksums of the individual files in the "Roaming\digikam\facesengine" folder.
The SHA256 checksums are correct. Compared to digiKam-7.1.0, basically only the storage location has changed. At the moment I am at a loss as the problem has been reported for the first time so far. Maik

What about this lines in the log which are the last when ending digikam? 00000474 490.48913574 [6640] QWaitCondition: Destroyed while threads are still waiting 00000475 492.12698364 [6640] QEventDispatcherWin32::wakeUp: Failed to post a message (Ungültiges Fensterhandle)
The lines at the end are caused by the crash. @Gilles If I change the model data here under Windows, digiKam simply crashes without a window. The window with the Visual C++ runtime makes me think. Are we linking against a Visual C++ runtime at all, I don't think so? Maik
Hi Maik, No definitively, digiKAm is not linked with MSVC, as all is cross compiled. linking with MSVC runtime is only necessary if a GUI component is used with DrMingw, and it's not the case, as i disable this feature. The DrMingw component dropped is the GUI to show the backtrace when crash appears. The trace is stored in a log file instead. It's indicated to the terminal at digiKam startup. Gilles
But after verification here : https://invent.kde.org/graphics/digikam/-/blob/master/project/bundles/3rdparty/ext_drmingw/CMakeLists.txt#L48 I remember to have updated DrMingw as Krita project, which extract and copy these file from the binary tarball : dbghelp.dll symsrv.dll Perhaps these files use MSVC runtime, i'm not sure...

The DebugView log shows that Windows 7 was correctly recognized and that DrMinGW was not installed. Maik
Ok, the OpenCV exceptions are now caught here under Linux and there is no longer a crash. With the next version of Windows, we might see what the problem is. Maik
A new digiKam-7.2.0 Windows version with the latest changes is available. Please test it and post the DebugView log from the start. There is no need to download the "-debug" version. https://files.kde.org/digikam/ Maik

It installs ok. while first start there is no download of facesengine and so no creating of the folder "C:/Users/jever.LOKAL/AppData/Roaming/digikam/facesengine". It starts up and runs well as far as I can see. Jever
The download must take place in any case if the files are not yet available. Please post the log to see if everything is really ok. Maik

I searched for the folder and recogniced that is already there. I looked at the wrong folder (Local user / domain user)! Sorry for the noise. Jever
The face recognition will not work, however, an exception occurs in OpenCV. It just doesn't crash anymore. -------------------------------------------------------------------------- [7152] digikam.facedb: "C:/Users/jever.LOKAL/AppData/Roaming/digikam/facesengine/openface_nn4.small2.v1.t7" [7152] digikam.facedb: cv::Exception: OpenCV(4.5.1) /mnt/data/7.x/project/bundles/mxe/temp.build/ext_opencv/ext_opencv-prefix/src/ext_opencv/modules/dnn/src/torch/THDiskFile.cpp:496: error: (-2:Unspecified error) cannot open <C:/Users/jever.LOKAL/AppData/Roaming/digikam/facesengine/openface_nn4.small2.v1.t7> in mode r in function 'THDiskFile_new' -------------------------------------------------------------------------- This is not a file not found error, it cannot be opened.

A new Windows version with the changes may be available tomorrow. It would be nice if you would test it and post a log. The problem with this OpenCV model loading function can often be found on the web, but unfortunately no real solution. Maik

Nice, the model could now be loaded without any problems. I would still try again with a UTF8 path as Char *. It is very unlikely that someone has a user name that cannot be resolved with the local 8-bit character table. So the cause is within OpenCV when dealing with file paths. Maik
