vscode调试C++工程

1. CMakeLists.txt中添加如下内容：

set(CMAKE_BUILD_TYPE "Debug")
set(CMAKE_CXX_FLAGS_DEBUG "$ENV{CXXFLAGS} -O0 -Wall -g2 -ggdb")

2. 在.vscode中添加launch.json 和 tasks.json两个文件。如下

launch.json文件如下："program"设置要调试的执行程序路径，${workspaceFolder}是当前文件夹目录

"args":包含了要传递给可执行文件的命令行参数,  程序以./demo arg1 arg2 --option 的形式运行

“miDebuggerPath"是gdb调试器的路径

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/demo",
            "args": ["arg1", "arg2", "--option"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description": "Set Disassembly Flavor to Intel",
                    "text": "-gdb-set disassembly-flavor intel",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

tasks.json如下：

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++ build active file",
            "command": "/usr/bin/g++",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

 

3. 代码设置断点后，点击vscode左侧边栏 （gdb）Launch，绿色run按钮即可进行调试

 

有时候代码可以正常运行，但调试时 出现一些error，此时是无法正常调试的。
