在OSX 10.9.1上用g ++编译时出错：未知类型名称'__darwin_wctype_t'
[英]Error when compiling with g++ on OSX 10.9.1: unknown type name '__darwin_wctype_t'
问题描述
When compiling even basic code (I attach a hello world as an example) on OSX 10.9.1 from the command line with g++ 
使用g ++从命令行在OSX 10.9.1上甚至编译基本代码时（我以一个世界为例）。
#include <iostream>
int main() {std::cout << "Hello World";}
I compile with the command: 我用命令编译：
g++ hello.cc -o hw
Which generates the following error messages: 生成以下错误消息：

Could you please try again after adding -I /usr/include like this 您可以在添加-I /usr/include像这样再试一次
g++ hello.cc -o hw -I /usr/include
I did the test on my computer OSX 10.10.3 (Yosemite), and found something more. 我在计算机OSX 10.10.3 （Yosemite）上进行了测试，发现了更多内容。
1) When compile with the command on my OS: 1）在我的OS上使用命令编译时：
g++ hello.cc -o hw
There is no error message. 没有错误信息。
2) After a few experiences, I found a way to reproduce the same error output. 2）经过几次经验，我找到了一种方法来重现相同的错误输出。 The command is as follows, 命令如下
g++ hello.cc -o hw -I /usr/include/sys
The output with error message like this, 带有错误消息的输出是这样的，

/usr/include/_types/_wctype_t.h:31:9: error: unknown type name '__darwin_wctype_t'
typedef __darwin_wctype_t wctype_t;
3) Furthermore, you can find more detailed information about your compiling with the command: 3）此外，您可以使用以下命令找到有关编译的更多详细信息：
g++ hello.cc -o hw -v
Then, you could check the included head files from the output as this 然后，您可以像这样从输出中检查包含的头文件

I just got a similar error message on MacOS 10.9 with clang++ 3.9, so I stumbled across this question. 我刚刚在使用clang ++ 3.9的MacOS 10.9上收到了类似的错误消息，因此我偶然发现了这个问题。
It turns out that I had forgotten to close a brace of a namespace declaration in a header file, which happened to be included before <iostream> . 事实证明，我忘记了在头文件中关闭命名空间声明的花括号，而该文件恰好包含在<iostream>之前。 With my setup, the following code reproduces the problem: 在我的设置中，以下代码重现了该问题：
namespace detail {
#include <iostream>
That was apparently not the OP's problem, but I hope that this will help others. 这显然不是OP的问题，但我希望这会对其他人有所帮助。
