编辑2：问题是不是简单的印刷错误。我在下面的日志中犯了一个拼写错误，我已更正该错误，但问题仍然存在。
编辑：在尝试下面之后，我错误地使用 gcc 而不是 g++ 运行了一次。 g++ 以前就存在这个问题，现在也存在。
我目前使用的是 MacOS High Sierra 盒子。我最近将很多文件从 MacBook Air 移至这台机器，其中包括我认为是 Xcode 的垃圾文件。现在，当我尝试编译一个非常简单的 C++ 程序时：
#include <iostream>
int main()
{
// VAR_DEC
int a = 4;
// VAR_MANIP
a = a*2;
// VAR_PRINT
std::cout << a << std::endl;
return 0;
}
我收到以下荒谬的错误：

我尝试安装并重新安装我能想到的与该问题相关的所有内容，例如gcc, g++, cc, brew, Xcode,command-line-tools等等。我还尝试了以下页面上的所有建议：
- 未知类型名称 uint8_t？
- 在 Mac OS X Yosemite 10.10.1 上包含搜索路径
- 由于未知类型名称“uint64_t”，Cythonizing 失败
- 未知类型名称“uint8_t”，MinGW
- JT Bullitt 非常全面的博客
还有更多，但这些总结得很好。所有解决方案均无效。
I think 最后一个有最可能的解决方案。 （如果您在页面上搜索“未知”，您将看到修复程序。）根据开发人员的说法：
修复：从“标题搜索路径”构建设置中删除 /opt/local/include/** 和 /opt/local/lib/** 。将它们替换为所需包含目录的更具体的路径。在我的特定情况下，这意味着用 /opt/local/include/glib-2.0 /opt/local/lib/glib-2.0/include /opt/local/include/ 替换它们。它又启动并运行了！
但是，我没有安装Xcode，我只安装了命令行开发者工具。因此，我没有一种简单的方法来访问“标题搜索路径”构建设置，因此我无法尝试他的解决方案。
我正在寻找解决此问题的方法，最好是不需要我安装整个操作系统的解决方案。或者，如果有人可以指导我找到构建设置文件，我将非常感激。
