我正在尝试运行:
#include <iostream>
int main() {
std::cout << "Hello World!";
return 0;
}
在我的Mac上。我在Visual Studio Code中安装了C++和Code Runner。但是我收到以下错误:
[Running] cd "/Users/NAME/Documents/Program/C++/" && g++ test.cpp -o test && "/Users/NAME/Documents/Program/C++/"test Undefined symbols for architecture x86_64: "_main", referenced from:
implicit entry/start for main executable ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

最佳答案
要构建并运行helloWorld.cpp或任何其他项目,您需要首先创建构 build 置。
考虑到您已经创建了helloworld.cpp
文件,然后执行以下步骤:
C/C++ clang++ build active file
(如果要使用gcc进行编译,则选择g++)来生成当前在编辑器中显示( Activity )的文件。 例如,我的
tasks.json
看起来像这样(我用过g++){
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "g++ build active file",
"command": "/usr/bin/g++",
"args": [
"-std=c++17",
"-stdlib=libc++",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
helloworld.cpp
。因为我们要构建helloworld.cpp
,所以重要的是,此文件应成为下一步在编辑器中处于 Activity 状态的文件。 tasks.json
中定义的构建任务,请按⇧⌘B或从终端主菜单中选择“运行构建任务”。 注意:这是对您在官方文档here中看到的内容的简短概述。您可以将glang替换为clang以进行gcc编译和构建。
终端输出:
xecuting task: /usr/bin/clang++ -std=c++17 -stdlib=libc++ -g /Users/Projects/test/helloworld.cpp -o /Users/Projects/test/helloworld <
Executing task: /usr/bin/g++ -std=c++17 -stdlib=libc++ -g /Users/Projects/test/helloworld.cpp -o /Users/Projects/test/helloworld <
