1 year ago error "C++ versions less than C++14 are not supported."
Latest protobuf uses abseil which requires to raise C++ standard (OpenCV uses C++11 by default). Try to build OpenCV with -DCMAKE_CXX_STANDARD=14 (or even 17).

1 year ago @mshabunin could you propose a pr with the patch?

1 year ago Yes, I'll take a look. A bit more testing with different protobuf versions is required for a good patch.

Take a look at https://github.com/protocolbuffers/protobuf/releases ? Your protobuf v3.23.3 is already the NEWEST release, right? I'm just using this NEWEST version. But I still got the above ERROR messages while building dnn caffe.
Looking forward to your PR.

1 year ago Finally resolved by installing the NEWEST protobuf v23.4.
Also, please refer to my PR: https://github.com/opencv/opencv/pull/23948 .

Steps to reproduce
Just build OpenCV from source, with the NEWEST protobuf pre-installed.
