使用 VSCode 设置 c++ 时遇到问题。包括错误、缺少二元运算符和未找到 xlocale.h

问题描述 投票：0回答：1

我正在尝试在 VSCode 上测试以下 C++ 代码，但似乎无法让它工作。截至目前，网上搜索尚未提供结果。尝试更改编译器，但似乎无法自行修复。不知道我如何进一步进行。操作系统是 ubuntu（如果相关）：

#include <iostream> //input output library, containing printing and asking input etc.

int main() {
    std::cout << "test"; //statement
    return 0; //tells system it terminated correctly
}

问题窗口下提到以下错误：

测试.cpp

#include 检测到错误。请更新您的 includePath。此翻译单元禁用波形图 (/mnt/F894C3B494C373A2/Downloads/c++/test.cpp)。

无法打开源文件“xlocale.h”（“iostream”的依赖项）

studio.h /usr/include

标记“(”之前缺少二元运算符 ..几次

libc-header-start.h /usr/include/x86_64-linux-gnu/bits

标记“(”之前缺少二元运算符

cdefs.h /usr/include/x86_64-linux-gnu/sys

标记“(”之前缺少二元运算符

终端窗口有以下输出：

更改了编译器，重新安装了其中一些编译器，并尝试将编译器更新到更高版本（已经是最新的）。

几个小时后，问题显然出在 mesa sdk 的固定标题行上。使用

GCC_VERSION=`gcc --version | grep ^gcc | sed 's/^.* //g'`
$MESASDK_ROOT/libexec/gcc/x86_64-pc-linux-gnu/$GCC_VERSION/install-tools/mkheaders $MESASDK_ROOT

解决了。
