2013-12-19 19:19:41 -0600 | asked a question | Undefined symbols cv::_OutputArray::_OutputArray(std::__1::vector<cv::Mat, std::__1::allocator<cv::Mat> >&) Hi everyone. I've been trying to incorporate OpenCV into a Kinect project I have going on OS X Mountain Lion (Xcode 4.6, OpenCV 2.4.7). Everything seemed to be going fine until I tried calling cv::calibrateCamera, which seems to require output args of class OutputArrayOfArrays. In the examples I see that references to std::vector<cv::mat> are passed in. The code compiles fine, but fails on the link with the following error: I've read that such errors might be because of a discrepancy between the c++ library against which the opencv libraries are linked and that against which the app code is linked. I've tried switching to libstdc++ in Xcode, and that seems to generate a whole slew of other errors which lead me to think that opencv 2.4.7 was updated with c++11 in mind? So, just in case, I went back and reconfigured the opencv build with the following. Unfortunately, I'm still getting the linker error. I don't think it's because I'm missing a library because this is a template invocation, so the code is generated at compile time, no? The code that seems to be causing the problem is as follows. Is there something wrong with my syntax? Am I missing some kind of typename qualifier or something? I've been banging my head against this for a couple of days now and would deeply appreciate any insight anyone may have. Thanks! |
