How to compile the code using #include <thread>
提问by q0987
I am trying to compile some C++ code that uses threads:
我正在尝试编译一些使用线程的 C++ 代码：
#include <iostream>
#include <thread>
void hello()
{
std::cout<<"Hello Concurrent World\n";
}
int _main(int argc, _TCHAR* argv[])
{
std::thread t(hello);
t.join();
return 0;
}
I get errors when compiling:
编译时出现错误：
c:\temp\app1\app1\app1.cpp(6): fatal error C1083: Cannot open
include file: 'thread': No such file or directory
~/Documents/C++ $ g++ -o thread1 thread1.cpp -D_REENTRANT -lpthread
In file included from /usr/include/c++/4.5/thread:35:0,
from thread1.cpp:2:
/usr/include/c++/4.5/bits/c++0x_warning.h:31:2: error: #error This file
requires compiler and library support for the upcoming ISO C++ standard,
C++0x. This support is currently experimental, and must be enabled with
the -std=c++0x or -std=gnu++0x compiler options.
How do I fix these errors?

<thread>and standard threading support is a new feature (defined in the C++11 standard). As for g++, you have to enable it adding -std=c++0xto the command line, as explained in the error message.
<thread>标准线程支持是一项新功能（在 C++11 标准中定义）。至于 g++，您必须启用它添加-std=c++0x到命令行，如错误消息中所述。
Also, you are using a nonstandard (Microsoft-specific) main, use the "classic" mainand normal char:
此外，您使用的是非标准（Microsoft 特定） main，使用“经典”main和正常char：
// thread1.cpp
#include <iostream>
#include <thread>
void hello()
{
std::cout<<"Hello Concurrent World\n";
}
int main(int argc, char * argv[])
{
std::thread t(hello);
t.join();
return 0;
}
Notice that not all C++11 features are available in current compilers; as far as g++ is concerned, you can find the status of their implementation here.
请注意，并非所有 C++11 功能都在当前编译器中可用；就 g++ 而言，您可以在此处找到它们的实现状态。

Yes, the header file <thread>is only standard in the C++11 newest standard (finalized this year only).
是的，头文件<thread>只是 C++11 最新标准中的标准（仅在今年完成）。
With GCC, you'll need the very latest 4.6version, and even with it, not everything is supported of the C++11 standard. See this table
使用 GCC，您将需要最新的4.6版本，即使有了它，C++11 标准也并非支持所有内容。看这张表

As far as MSVC goes, the C++11 <thread>header isn't supported in VS2010 - you'll need to pull down a Developer Preview of Visual Studio 11 (http://msdn.microsoft.com/en-us/vstudio/hh127353) to try it out today.
就 MSVC 而言，<thread>VS2010 不支持C++11 标头 - 您需要下拉 Visual Studio 11 的开发人员预览版 (http://msdn.microsoft.com/en-us/vstudio/ hh127353）今天就试试。
See http://blogs.msdn.com/b/vcblog/archive/2011/09/12/10209291.aspxfor details on what is new in C++ for Visual Studio 11.
有关Visual Studio 11 的 C++ 新增功能的详细信息，请参阅http://blogs.msdn.com/b/vcblog/archive/2011/09/12/10209291.aspx。
Also, my PDF of the book (which is in pre-release at the moment) has the following definition of main():
此外，我的这本书的 PDF（目前处于预发布阶段）具有以下定义main()：
int main()
{
std::thread t(hello);
t.join();
}
which avoids the problems you're running into with _TCHARbeing undefined in GCC.
这避免了您_TCHAR在 GCC 中未定义时遇到的问题。
