openCV in visual studio 2012

Question

I am getting an error [I get an error opencv_core242.dll is missing] when trying to compile a test program from http://karanjthakkar.wordpress.com/2012/11/21/usin-opencv-2-4-2-with-visual-studio-2012-on-windows-7-64-bit/ .

I tried to add the specified information in something called a environment variable, however I do not know if I am doing it correctly. Can anyone clearly state step-by-step what I am supposed to do to add as the value? I put the paths to the directories that I need but it doesn't seem to resolve this error when I try to build the program.

Answer 1

@Code Head has got one of the answer.

Or you can just copy all the dll's in opencv/build/vc11/bin into your program directory.

I know this is really an ugly solution but this surely works for a starter. At least I myself find it really useful when I first started using OpenCV.

Answer 2

Here's what you need to do:

1. RightClick your project in "Solution Explorer"
2. Click Properties
3. Navigate to "Configuration Properties -> Debugging"

4. In "Local Windows Debugger -> Environment" Write:

   • Path=$(Path);C:\\path_to_opencv\\build\\x86\\vc11\\bin

     or (if compiling 64 bit):

   • Path=$(Path);C:\\path_to_opencv\\build\\x64\\vc11\\bin
