xutility file???
- by user574290
Hi all.
I'm trying to use c code with opencv in face
detection and counting, but I cannot build the source.
I am trying to compile my project and I am
having a lot of problems with a line in the xutility file.
the error message show that it error with xutility file.
Please help me, how to solve this problem?
this is my code
