Hi, I have just started using Opencv recently and I keep on getting an error when trying to run my project.

The program can't start because libopencv_core242.dll is missing from your computer

I'm using OpenCV 2.4.5 with Code::blocks 12.11 on a Windows 7 64bit PC.

I installed OpenCV to the C: drive.

I have added the "C:\opencv\build\x86\mingw\bin" directory to my system path, added the "C:\opencv\build\include" directory to the search directories in the compiler settings and added all the .a libraries in the "C:\opencv\build\x86\mingw\lib" directory to the linker settings in the compiler settings.

I'm using the GNU GCC compiler. I have checked that the libopencv_core242.dll file is in fact in the "C:\opencv\build\x86\mingw\bin" directory. Am I missing something?

Any help would be greatly appreciated.

Just some things I do extra on my Windows system, but could help you. Also add to your include directories:

  • C:\opencv\build\include\opencv\
  • C:\opencv\build\include\opencv2\

Also be sure not to have added the debug dlls instead of the release ones, depending on what you need.

Check if your destination target system is configured correctly: x86 or x64 system.

I tried everything but I'm still getting the error. If I run the .exe directly it works though.

If it is only generating the error in your debugging environment, there must be something wrong with your codeblocks execution parameters.

Do you know what the execution parameters should be?

Nope, have no experience with codeblocks whatsoever :)
