$ gcc 12.c -fopenmp
12.c:9:9: fatal error: 'omp.h' file not found
#include<omp.h>
    ^
1 error generated.

在编译openMP程序时,我得到了上述错误.我正在使用OS X Yosemite.我首先尝试通过在终端中键入gcc来安装本机gcc编译器,后来又下载了Xcode,我得到了同样的错误.然后我下载了gcc:

$ brew install gcc

我仍然得到同样的错误.我确实尝试更改编译器路径,它仍显示:

$ which gcc
/usr/bin/gcc

那么如何用gcc编译程序呢？

我用c++和OpenCV写了一段代码：

#include <iostream>
#include <time.h>
#include <opencv2/opencv.hpp>
#include <opencv2/highgui.hpp>

using namespace std;

int main()
{
    ...
    return 0;
}

然后我尝试在终端上运行我的代码并使用 g++ 进行构建：

g++ $(pkg-config --cflags --libs opencv) -std=c++11  yourFile.cpp -o yourFileProgram

但我收到此错误：

...
