I have a prosilica (allied vision) manta G032C GiG-E camera that I am trying to get working with OpenCV 2.4 under Ubuntu Linux 12.04. Currently I have the Prosilica camera drivers installed and can run the SampleViewer application and see images fine. What I am trying to do now is build OpenCV with the PvAPI wrapper that is included.

I tried to run:

cmake -D WITH_PVAPI=ON ..

from the build directory, but the status output looks like this:

It looks to me like the library finder in OpenCVFindLibsVideo.cmake is broken. You can pass the location of the library to cmake directly. On my system I have a symlink to the library in /usr/local/lib, so I added:

-D PVAPI_LIBRARY="/usr/local/lib/libPvAPI.a"

Thank, I now see that the wrapper is is marked as yes to build. I am trying to run the example application here: https://github.com/xamox/OpenCV-Camera/blob/master/show-camera.cpp

Except I've uncommented the: CvCapture* capture = cvCaptureFromCAM( CV_CAP_PVAPI )

It will build but I'm getting capture is NULL.
