I have a problem. My compiler says that "fatal error: opencv2/core/utility.hpp: No such file or directory compilation terminated". There isnot the file in my opencv2 folder. What should I do?

I read this title ,but I dont understand the solution.

opencv version is 2.3.1

opencv2/core/utility.hpp is probably from 3.0 code (master). getTickCount(), format() and such were moved there.

on 2.3.1 just include opencv2/core/core.hpp

if that's from one of the samples, you want to select the proper 2.4 branch, not 3.0

I tried it but there are many error on compile.

ok. leave it. it expects 3.0, you got 2.3.1.

is it one of the opencv samples ? maybe we can help you find one fitting to your version
