System Information

OpenCV Python version: 5.0.0-pre (commit d976272)
Operating system / platform: Manjaro on Udoo Bolt v8

Detailed description

On my system, when using UMat input, minMaxLoc outputs the following OpenCL compilation error and then the whole system locks up:

OpenCL program build log: core/minmaxloc
Status -11: CL_BUILD_PROGRAM_FAILURE
-D DEPTH_0 -D srcT1=uchar -D WGS=256 -D srcT=uchar4 -D WGS2_ALIGNED=128 -D DOUBLE_SUPPORT -D HAEV_SRC_CONT -D HAVE_MASK_CONT -D kercn=4 -D NEED_MAXVAL -D dstT1=uchar -D dstT=uchar4 -D convertToDT=noconvert -D wdepth=0 -D convertFromU=noconvert -D MINMAX_STRUCT_ALIGNMENT=8 -D AMD_DEVICE input.cl:8:1: error: OpenCL C version 1.1 does not support the 'static' storage class specifier

Based on the error message, I guess a similar problem would affect all systems running OpenCL 1.1.

Expected behaviour: The function should fall back to a compatible CPU implementation if the system lacks the necessary features for the OpenCL-accelerated implementation.

Steps to reproduce

Run minMaxLoc with UMat input on a system with OpenCL 1.1.

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)
