用于OpenCV C++接口的Emacs CEDET

Question

因此，我现在已经使用了CEDET一段时间，而且一般情况下它的工作情况非常好。 我正在从使用C到C++，特别是OpenCV 2.3（linux），我遇到了问题。我正在使用emacs24和最新的CEDET开发版。

这是无法解析某些符号及其成员，如：KeyPoint, Mat,等

许多功能符号但是被解析，如line(), imshow(), imread()等

我在寻求帮助如何调试我的设置有什么问题，或者成功安装opencv C++ api的人。

这里是我的相关CEDET配置：

我有一个工作配置现在;感谢cedet-devel邮件列表中的Alex Ott和David Engster。要注意他们的修正，我的配置中有一些“不需要，可能会伤害”的行。更新配置后，删除〜/ .semanticdb中的所有文件并重新启动emacs，事情就像预期的那样工作！

我还包括一个示例cpp文件来测试配置。多谢你们！

和自备电厂的测试文件：

#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

它看起来像，语义分析器无法分析类的声明 - 它把它看作CV_EXPORTS Mat不是Mat本身虽然CV_EXPORTS应扩展到空字符串。我使用了下面的配置，它对C代码很好，但对C++不适用。我建议你写CEDET-devel邮件列表与实例 - 只是写在那里，如果有必要，我会为你的邮件更多评论...
