use vscode mingw cmake on windows

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} )

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.

}

需要配置用 cmake:configure with cmake debugger

在这里插入图片描述

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]}
}
