c++ - 无法在 VS Code 中多次使用预启动任务

Question

我尝试多次使用预启动任务来执行我的 launch.json 文件中的两个不同任务。不幸的是，它只执行我的 launch.json 文件中的最后一个预启动任务。我的 tasks.json 中的任务使用相同的命令(“g++”)来编译我的程序，但它们的参数不同(那是因为我需要先将我的源代码编译成一个“O”文件然后编译“O” "文件转换为 "exe"文件)，所以我正在寻找一种方法，了解如何仅使用一个预启动任务在 launch.json 文件中执行这两个任务。还有其他想法吗？

任务.json:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "0.1.0",
    "tasks": [
        {
            "taskName": "CompileToOfile",
            "command": "g++",
            "args": [
                "-c","${fileBasename}",
                "-o","${fileBasenameNoExtension}.o",
                "-I","/Users/Acer/MinGW64/include",
                "-I","/Users/Acer/MinGW64/x86_64-w64-mingw32/include",

                "-m32"
            ],
            "isShellCommand": true
        },
        {

            "args": [
                "${fileBasenameNoExtension}.o",
                "-o",
                "${fileBasenameNoExtension}.exe",
                "-L","/Users/Acer/MinGW64/lib32",
                "-L","Users/Acer/MinGW64/x86_64-w64-mingw32/lib32",

                "-lcomdlg32",

                "-loleaut32",
                "-lole32",
                "-m32"
            ],
            "isShellCommand": true
        }
    ]
}

        }
    ]
}

您只能有一个preLaunchTask，但您可以将"dependsOn": "CompileToOfile" 添加到您的CompileWGDBWBGI 任务，然后使用它作为您的 preLaunchTask。这样，CompileToOfile 在每次执行 CompileWGDBWBGI 之前执行。
