you see the mismatch ? when building the opencv libs ( esp. highgui ), it did not find gtk2, so that module was built without gui support and throws a runtime exception, when you try to open a window. (anything else, like videocaptuer and imread, should still work fine, though)
cv::Exception::what() is just the function, that retrieves the message from the exception. please remove that part from your title, as it's totally misleading.
again, your problem is missing gtk2.

cv::Exception::what() so actually, imshow() (or namedWindow(), whatever you were trying to use from highgui) is the function, that is not implemented.
