I am using cvCanny function in opencv 2.3 it compiles fine,but while executing it gives an error saying 'tbb.dll' not found.

What is the use of this dll and where can I find this??

thanks,

It's part of Intel's Threading Building Blocks library.

You can find a copy of it in your OpenCV install in /build/common/tbb and under the platform and compiler your are using. For example, in c:\OpenCV-2.3.1\build\common\tbb\intel64\vc9

  • Thanks, So do I need to download it and add it in my executables? – ATG Jan 11 '12 at 12:05
  • Just download it and put it in the directory from where you run your application or just into Windows/System32 – Toby Jan 11 '12 at 12:17
