• Compiler => g++ 11.4.0

Detailed description

Hi all,
I'm trying to compile the last OpenCV with the OpenCV Matlab Code Generator module enable in order to call OpenCV methods in Matlab. I was previously using https://github.com/kyamagu/mexopencv when on OpenCV 3. After a new install on my machine and a try with OpenCV 4, I can't make it work.

After successfully running cmake, running make leads to the following errors:

Could anyone assist me or help me on this ?
