生成C文件时，vscode报告活动文件不是C或C++源文件

Question

vscode在生成c程序时报告错误。错误消息如下。

Cannot build and debug because the active file is not a C or C++ source file.
The terminal process failed to launch (exit code: -1).

任务配置文件如下所示。

{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++ build active file",
"command": "/usr/bin/gcc",
"args": [
"-fdiagnostics-color=always",
"-g",
"/home/xxx/tmp/test/main.c"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}

我在文件夹/home/xxx/tmp/test下有一个名为main.c的c文件，它是工作区文件夹。问题的原因可能是什么？

Answer 1

正如Sean McManus的回复所示，您需要删除tasks.json中的所有${file}引用，例如：

"args": [
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${fileDirname}"
}

更改为

"args": [
"-g",
"test.cpp",
"-o",
"libs/test.o"
],
"options": {
"cwd": "${fileDirname}"
}

并将构建类型从cppBuild更改为shell。
