Disable multi core in parallel_for_ function

parallel_for_

I want to deny OpenCV from run on multicore. I have built a version without (OpenCL, IPP, CUDA, TBB). However, any OpenCV function that contains parallel_for_ is working on parallel. How can I stop those function from multi cores and stick to only one core?

Note: I am using OpenCV 3.1 on MS Windows OS and Intel processor.

You can fixed number of thread using SetNumThread to 0. some behaviour differs from framework...

That being said, did you check if pthread support was disabled? you should verify that any parallelization framework is disabled in your build if you want no parallelization at all.
