I am running into issues building an existing 32-bit EmguCV ( Version 2.3 )

  • 0

I am running into issues building an existing 32-bit EmguCV (Version 2.3) into 64-bit using .net 4.0 and VS2010 on a W7/x64 OS. I have purchased a commercial license, if that matters and downloaded from the links provided in the receipt.

The error is 

System.TypeInitializationException was unhandled
 Message=The type initializer for 'Emgu.CV.CvInvoke' threw an exception.
 Source=Emgu.CV
 TypeName=Emgu.CV.CvInvoke

I followed the instructions provided in this article. In fact I used the samples projects in the article and they build fine with V2.2, but when I replace with V2.3 binaries (both emgu and opencv), run into the error.

Has anyone successfully built an Emgu (Version 2.3.x) x64 project? Please provide some guidance.

    The cause of this error (should anyone else run into the same problem) is that the program cannot access opencv_imgproc231.dll or opencv_core231.dll even though they are present in the output “bin” directory.

    There are two solutions:

    1. Add them to the project and set their properties to copy always as they are EMGU’s two key files.

    2. If step 1 doesn’t work, replace the current key files in the bin folder with new copies.

    If both methods fail then there may be a problem with the build, so download a new copy of EMGU from Sourceforge and try again. The error will later be incorporated within an technical article in order to provide a clearer explanation of how to solve it.

    Cheers,
