use vscode mingw cmake on windows-Toy模板网

这篇具有很好参考价值的文章主要介绍了use vscode mingw cmake on windows。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

记住mingw去官网下面的MingW-W64-builds, 下这个版本
x86_64-13.1.0-release-posix-seh-ucrt-rt_v11-rev1.7z
posix很重要, win32版本没线程支持,用到会报错

可以测试下是否能正常运行

#include <thread>
#include <mutex>
#include <condition_variable>
#include <iostream>

std::thread second_workthread;
std::mutex mtx;
std::condition_variable objectDetectorRun;

task.json
安好mingw, cmake

            },
        }
    ]
}

对于opencv, 要么自己用Mingw编译, 要么下载现存的, 我这里下的现成的https://github.com/huihut/OpenCV-MinGW-Build

cmake_minimum_required( VERSION 3.5 )
project( main )

set(CMAKE_CXX_FLAGS "-std=c++14")
set (OpenCV_DIR C:\\Software\\OpenCV-MinGW-Build)
find_package(OpenCV REQUIRED)

include_directories(${OpenCV_INCLUDE_DIRS})


add_executable( main main.cpp )
target_link_libraries( main ${Pangolin_LIBRARIES} )

注意把opencv的bin加入Path,不然找不到opencv的dll. 程序运行和调试都会有错, 特别是调试会出现During startup program exited with code 0xc0000135. 就是DLL找不到的问题

debug的话

launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "targetArchitecture": "x86",
            "program": "${command:cmake.launchTargetPath}",
            // "program": "${workspaceFolder}/build/main.exe",
            // "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": ["32"],//左边启动debug, 从这里pick up args
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}/build",
            "environment": [
                {
                    "name": "PATH",
                    "value": "${env:Path};C:\\Workspace\\v-nova\\build"
                    //这里设置错了,容易出现Unable to start debugging. Unexpected GDB output from command “-exec-run“
                }
            ],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "C:/Software/mingw64/bin/gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
        }
    ]
}

需要配置用 cmake:configure with cmake debugger

use vscode mingw cmake on windows,vscode,windows,ide

注意最下面的状态栏, 如果没有设置点进去设置
另外 cmake可能会让把

C:\Software\OpenCV-MinGW-Build\x64\mingw\bin

加入环境变量

如果传参在launch.json 不work的话, 在setting.json里面加上

从状态栏启动debug的话, 设置 args要在setting.json里面

{
    "cmake.configureOnOpen": false,
    "files.associations": {
        "ostream": "cpp",
        "mutex": "cpp",
        "array": "cpp",
        "string": "cpp",
        "string_view": "cpp"
    },
    "C_Cpp.default.compilerPath": "C:\\Software\\mingw64\\bin\\g++.exe",
    "cmake.debugConfig": {
        "args": [
            "32"//下面启动debug从这里Pick up args
        ]
    }
}
