Emacs CEDET for OpenCV C ++ interface

Question

So, I used CEDET for a while, and everything works well overall. I am moving from using it from C to C ++, especially for OpenCV 2.3 (linux), and I'm having problems. I am using emacs24 with the latest version of the CEDET developer.

It is not possible to parse some characters and their elements, for example: KeyPoint, Mat, etc.

However, many AES functional characters are parsed, for example line(), imshow(), imread() , etc.

I am looking for help on how to debug errors in my setup or someone who has successfully configured opencv c ++ api.

Here is my relevant cedet configuration:

Answer 1

Now I have a working configuration; thanks to Alex Ott and David Engster on the cedet-devel mailing list. To mark their corrections, there were some lines in my configuration that were "not needed and possibly harmful." After updating the configuration, deleting all files in ~ / .semanticdb and restarting emacs everything works as expected!

I also included a sample cpp file for testing the configuration. Thanks guys!

And the CPP test file:

 #include <stdio.h> #include <vector> #include <string> #include <opencv2/opencv.hpp> #include <opencv2/core/core.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/features2d/features2d.hpp> #include <opencv2/highgui/highgui.hpp> using namespace cv; using namespace std; int main(int argc, char **argv) { KeyPoint k; Mat m; // m should have members like m.clone() // k has members like k.pt (Point2f pt) return 0; } 

Answer 2

It seems that the semantic parser could not parse the class declaration - it considers its CV_EXPORTS Mat not like Mat itself, although CV_EXPORTS should be expanded to an empty line. I used the following configuration, and it worked fine for C code, but not C ++. I suggest you write a cedet-devel mailing list with examples - just write there, and if necessary I will provide more comments for your mail ...
