Why?为什么？

The pthread library is not compatible with Windows. pthread 库与 Windows 不兼容。 Don't worry, there is a library for that.别担心，有一个图书馆。 Called pthreads-win32 , you could also try std::thread but your code seems mostly c so better stick to pthread称为 pthreads-win32 ，您也可以尝试std::thread但您的代码似乎主要是c所以最好坚持pthread

Just downloaded Dev-C++ and checked, mingw does include the header files for pthread but don't let this confuse you.刚刚下载 Dev-C++ 并检查，mingw 确实包含pthread的头文件，但不要让这让您感到困惑。 Pthread is not compatible with Windows, so the implementation will not link. Pthread 与 Windows 不兼容，因此实现将不会链接。

How to link pthread win32?如何链接pthread win32？

Check the Tools -> Compiler Options -> Directories and add the proper directories for your library pthread win32.检查工具 -> 编译器选项 -> 目录并为您的库 pthread win32 添加适当的目录。

And then add the command in Tools -> Compiler Options -> General for your library like this -llibpthread-win32 or the name you installed for the lib on your system.然后在 Tools -> Compiler Options -> General 中为您的库添加命令，例如 -llibpthread-win32 或您为系统上的 lib 安装的名称。

What if I want to go C++ and `std::thread` all over the program如果我想在整个程序中使用 C++ 和`std::thread`怎么办

Just check that the version of your mingw for C++11 compatibility by adding the command -std=c++11 to your compiler.只需通过向编译器添加命令 -std=c++11 来检查您的 mingw 版本是否与 C++11 兼容。 I suggest the newest version of g++ 4.8 since it includes the tool thread sanitizer.我建议使用最新版本的 g++ 4.8，因为它包含工具线程消毒器。
