vscode运行已编译好的程序

假设我有一个项目，已经编译好了，需要调试，用gdb命令行调试不熟悉，还是用vscode来调试比较好。

编写Launch.json:

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

关键点："preLaunchTask": "",这个是空的，就不会去编译了，直接运行。

envFile的内容跟shell文件一样：

PATH="/opt/qt-5.15.2/bin:./:$PATH"
LD_LIBRARY_PATH="/home/user/work/xxx/cmakeBuuild/build/lib:/usr/local/hdf5/lib:/opt/gt-5.15.2/lib:/usr/local/lib:./:$LD_LIBRARY_PATH"
QT_PLUGIN_PATH="/opt/qt-5.15.2/plugins:$QT_PLUGIN_PATH"
QML2_IMPORT_PATH="/opt/qt-5.15.2/qml:$QMIL2_IMPORT_PATH"
INCLUDEPATH="/opt/qt-5.15.2/include:$INCILUDEPATH"

这个.env会设置环境变量。
