如何在vscode上使用C ++ 11兼容模式进行编译?

测试文件

#include <iostream>

using namespace std;

void print()
{
    int v[] = {0,1,2,3,4,5,6,7,8,9};
    for (auto x : v) {
        cout << x << '\n';
    }

    for (auto x : {10,21,32,43,54,65}) {
        cout << x << '\n';
    }
}

int main() {
    print();
}


task.json

{
    "version": "0.1.0",
    "command": "g++",
    "isShellCommand": true,
    "args": ["-O2", "-g", "test.cpp"],
    "showOutput": "always"
}


错误

test.cpp:8:10: warning: 'auto' type specifier is a C++11 extension [-Wc++11-extensions]
    for (auto x : v) {

$ gcc -v

最佳答案

听起来像gcc的旧版本。你应该升级!

您可以通过更改使它起作用

"args": ["-O2", "-g", "test.cpp"],




"args": ["-std=c++11", "-O2", "-g", "test.cpp"],


但是,实际上,请考虑升级。

关于c++ - vscode上的编译错误。类型说明符是C++ 11扩展,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/44171350/
