Dear all,

I just finished to download and compiled OpenCV 4. I've got a lot of errors, essentially using "old" OpenCV version program like 3.2. I received this kind of message:

undefined reference « cv::String::allocate(unsigned long) »

Could you please explain me why ?

What do I need to do to solve those issues ?

Thanks for your help and support.

Regards,

what does it mean, exactly ?

can you show the relevant portion of your code here ?

indeed, there are changes, the cv::String implementation was dropped, and replaced with std::string
