vscode配置C++和Opencv(ubuntu18.04)

安装opencv参考:Ubuntu18.04安装Opencv4.5(最新最详细)
配置vscode参考:
         Ubuntu20.04/Ubuntu22.04 配置VScode+Opencv+cmake(C++)
         Ubuntu环境下VScode配置OpenCV的C++开发环境
         vscode配置C++编译运行环境(Ubuntu)

新建一个文件夹,并新建 .cpp 的 opencv测试文件

#include
#include
using namespace std;
using namespace cv;
int main(int argc,char** argv){
	Mat src = imread("test.jpeg",IMREAD_GRAYSCALE); //读取图片
	if (src.empty()) {                     //判断是否找到图片
		printf("没有找到图片 ");           //输出文字
		return -1;
	}
	else
	{
		namedWindow("input",WINDOW_AUTOSIZE);// 显示窗口命名为input ;WINDOW_AUTOSIZE显示大小为图片自定义大小,且不可以更改大小
		imshow("input",src); //显示
		waitKey(0);//显示的毫秒时间,如果函数参数<=0表示一直显示。>0表示显示的时间
		destroyAllWindows();
		return 0;
 
	}
}

首先要把以下三个文件弄出来

vscode配置C++和Opencv(ubuntu18.04)_第1张图片

配置编译器:c_cpp_properties.json
配置构建任务:tasks.json
配置调试设置:launch.json

c_cpp_properties.json :shift+ctrl+p搜索全局命令,搜索C/C++ Edit Configurations(UI)

添加:

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "/usr/include/x86_64-linux-gnu/sys",
                "/usr/local/include/opencv4",			//记得把opencv4的include路径包含,按我上述方法来安装opencv的话一般就是这个路径
                "/usr/include/x86_64-linux-gnu/sys"		//这是装了cuda的路径,如果无cuda请去除
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "gnu17",
            "cppStandard": "gnu++17",
            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4
}

tasks.json

快捷键shift+ctrl+p搜索全局命令tasks,选择g++ 生成活动文件


{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++ build active file",
            //"command": "/usr/bin/cpp",                  //不能用这命名, 否则你可能会i报错 gdb failed with message 'file format not recognized'
            "command": "/usr/bin/g++", 
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}.out",
                "`pkg-config","--libs","--cflags","opencv4`"	//这是添加第三方库代码,要添加什么库直接继续加就行,不要忘记了 ` 符号
                //如下面再加个 gazebo11 第三方库(你得保证你安装的第三方库中含有.pc文件)
              // "`pkg-config","--libs","--cflags","opencv4,gazebo11`"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ],
    "version": "2.0.0"
}

 launch.json:

运行——>添加配置——>C++(GDB/LLDB)——>

{
    "configurations": [
        {
            "name": "C/C++: cpp 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}.out",
            "args": [
                "`pkg-config","--libs","--cflags","opencv4`",
            ],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description": "将反汇编风格设置为 Intel",
                    "text": "-gdb-set disassembly-flavor intel",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: g++ build active file",		//要和 task.json的label字段一致
            "miDebuggerPath": "/usr/bin/gdb",
            //下面这行命令可以去除Vscode中编译后出现 [1]+   Done....  的提示
            "miDebuggerArgs": "-q -ex quit; wait() { fg >/dev/null; }; /usr/bin/gdb -q --interpreter=mi"
        }
    ],
    "version": "2.0.0"
}

如果想生成一个终端可以改:"externalConsole": true ,弹出命令窗口

都保存后运行即可(F5)
