SUMMARY 8.5.0 properly detects and uses my GPU (Nvidia RTX 3070) for OpenCV Also working is digiKam-8.6.0-20250118T140205-Qt6-Win64 The currently weekly does not: digiKam-8.6.0-20250308T140208-Qt6-Win64 STEPS TO REPRODUCE 1. Install the named versions 2. Check "Help > Components Information > OpenCV Configuration" OBSERVED RESULT In working versions, it shows an OpenCL Platform of "NVIDIA CUDA" EXPECTED RESULT OpenCL working in current weekly.

The OpenCL enabled logic was changed some time ago. Make sure that you have enabled OpenCL in the digiKam setup under Miscellaneous-> System. Maik

@Gilles, since openCV-4.9.0 we have to enable [opencl] as an option for vcpkg, probably also [cuda] and [dnn] and [dnn-cuda]. The question is, do we still do it for digiKam-8.6.0 or do we only do it for the upcoming 8.7.0? Maik
Hi Maik, OpenCV is updated to 4.10 now in VCPKG. So for 8.7.0 we will update to this version as well. https://vcpkg.io/en/package/opencv For your Q, i don't know. We will see after the OpenCV update. Best Gilles
Maik, Look the "Features" tab from https://vcpkg.io/en/package/opencv option enabled or not by default are listed. Best Gilles Caulier
In openCV-4.8.0 openCL was activated by default, from openCV-4.9.0 there is a configuration option and this is deactivated by default. We are already using openCV-4.10, so we have to activate openCL. Maik
Git commit 443bd31cd5f9babda87f7da46dae3701492cd7a8 by Maik Qualmann. Committed on 09/03/2025 at 07:02. Pushed by mqualmann into branch 'master'. enable opencl in the vcpkg build M +1 -1 project/bundles/vcpkg/01-build-vcpkg.sh https://invent.kde.org/graphics/digikam/-/commit/443bd31cd5f9babda87f7da46dae3701492cd7a8
Hi gents, The latest build, digiKam-8.6.0-20250312T100200-Qt6-Win64.exe, still shows a "No" for "OpenCL Availability". I can attach the full Component Info if it'd be helpful. (I'm working under the assumption that the patch to enable opencl in the vcpkg build would make it to the builds at https://files.kde.org/digikam/ ) Cheers, and thanks for all you do
yes, the VCPKG build of opencv package need to be run again to take effect.
Hi again! I built git rev c409c079115e92b819b374b813d3a3091b90ca1b after patches related to this were committed and confirmed OpenCL was working properly with my RTX 3070. I just installed the stable release of 8.6 and it still is not, though. (OpenCL availability is still "No" in component info.) The 2025/04/08 prerelease of 8.7 also shows no OpenCL availability.
The VCPKG build of 8.7.0 pre-release was not yet rebuild from scratch. I will do it soon, including the last opencv build rules introduced by Maik. Gilles Caulier
The Qt5 and Qt6 8.7.0 pre-release installers for Windows are started to build few minutes ago. If all compile fine, files will be available this evening...
Hi Good news : the Qt5 and Qt6 build + Opencv with CUDA support are ready on the both Win10 WM. This has required to install the NVIDIA CUDA DNN SDK on both VM. Bad news: kimageformat Qt5 and Qt6 do not pass. It's the same error. I don't yet investigated in-deep.

Found the problem : LINK : fatal error LNK1104: cannot open file 'm.lib' [E:\b\dk_cmake\ext_kf6\ext_kimageformats-prefix\src\ext_kimageformats-build\src\imageformats\kimg_jxl.vcxproj] [E:\b\dk_cmake\ext_kf6\ext_kimageformats.vcxproj] m.lib is the math library... under Linux, not under Windows. There is probably a mess in the cmalekists.txt somewhere in kimageformat module. Gilles

The VCPKG UPSTREAM bug : https://github.com/microsoft/vcpkg/issues/44979 digiKam compile now using patched described in the VCPKG issue.
The Qt5 and Qt6 8.7.0 pre-release installers for Windows are now online with the OpenCV compiled with the NVIDIA OpenCL DNN API. It's ready to test. Maik : note about the NVIDIA API: VCPKG ask to install 2 proprietary API packages from NVIDIA to compile OpenCV with the new options : OpenCL + OpenCL-DNN. After this install OpenCV compilation pass fine. Best Gilles
Hi Gilles, The Windows Qt6 bundle does not start, 2 missing DLL files are reported, cublas64_12.dll and cudnn64_9.dll. Maik
Thanks Maik i will includes these files now. Gilles

Created attachment 180178 [details] Intel 620 's openCL support is properly detected as well
Great thanks you for your feedback. I close the Intel GPU opencl report now...

Thank you! I was starting to type out a bug report when I found this. I'm running digiKam-8.7.0-20250425T130207-Qt6-Win64 and it is finally detecting my dGPU. Thanks for fixing the problem, you guys rock!
