Atom利用gcc-make-run编译opencv工程

0、起什么标题呢？（就叫写在前面的话吧）

Atom插件的安装参照这篇文章，opencv的配置参考这篇文章（不使用CodeBlocks的话，解压后只需要添加相应的环境变量即可）。
之前就是想设置Atom能够编译opencv工程，Atom的gcc-make-run插件是利用MinGW的gcc/g++编译C/C++代码，要添加其对opencv的支持，实际上只需要在编译时进行相关库文件的链接即可。对codeBlocks配置opencv后，我写了一个简单的图片显示代码进行测试，编译时发现Build log下有编译链接库的命令，然后就是根据这个改了一下gcc-make-run的设置，能够正确编译opencv代码并运行。

1、设置

打开Atom，按下快捷键Ctrl+Shift+P，输入install package，点击第一个进入设置管理。

找到安装的gcc-make-run插件，点击设置对插件编译选项进行设置

参数 作用 -Wall 表示允许gcc提供可用的警告信息 -g 表示在编译时产生调试信息 -Idir 此处为包含opencv头文件所在目录 -Ldir 指定opencv链接库的路径

在Complier Flags里面添加的编译选项是opencv头文件的链接路径，Link Libraries添加的为链接库的路径。实际设置时，要根据自己opencv所在路径进行相应修改，例如在我的电脑上，opencv路径为E:\OpenCv_Code\CodeBlocks1601\opencv3，那么我的配置如下：

1.1.Compiler Flags添加如下：

-Wall -fexceptions -g -IE:\OpenCv_Code\CodeBlocks1601\opencv3\build\include -IE:\OpenCv_Code\CodeBlocks1601\opencv3\build\include\opencv -IE:\OpenCv_Code\CodeBlocks1601\opencv3\build\include\opencv2

1.2.Link Libraries添加如下：

-LE:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_calib3d310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_core310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_features2d310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_flann310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_highgui310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_imgcodecs310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_imgproc310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_ml310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_objdetect310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_photo310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_shape310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_stitching310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_superres310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_ts310.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_video310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_videoio310.dll.a E:\OpenCv_Code\CodeBlocks1601\opencv3\build\x86\mingw\lib\libopencv_videostab310.dll.a

2、代码测试

随意新建一个目录，在目录里新建一个cpp文档并拷贝一个test.jpg图片到该目录，使用Atom打开，输入如下代码，按F6编译执行：

#include <iostream>#include <opencv2\core\core.hpp>#include <opencv2\highgui\highgui.hpp>#include <opencv2\imgproc\imgproc.hpp>using namespace std;using namespace cv;int main(){    cout << "Hello world!" << endl;    Mat img = imread("test.jpg");    imshow("test", img);    cvtColor(img, img, CV_RGB2GRAY);    imshow("gray", img);    waitKey(0);    return 0;}
