mingw.thread.h头文件安装不当

Question

I originally asked a question regarding issues I am having getting the #include header file to function correctly. C++ multithreading errors . Specifically, I get the error that "'thread' was not declared in this scope". I am beginning to wonder if my original assumption that I was installing the mingw.thread.h header file incorrectly (located here: https://github.com/meganz/mingw-std-threads ). This seemingly helps solve these issues for many people,

Can someone provide a description of how to install this file correctly?

These are the results when I run gcc -v on my terminal:

Using built-in specs.

edit: To help, when I include the "mingw.thread.h" and compile, I get these errors:

error: #error To use the MinGW-std-threads library, you will need to define the macro _WIN32_WINNT to be 0x0501 (Windows XP) or higher.

#error To use the MinGW-std-threads library, you will need to define the macro _WIN32_WINNT to be 0x0501 (Windows XP) or higher.

Answer 1

To use this header follow the instructions .

1. Download the mingw.thread.h header and save it somewhere on your include path.
2. Change #include <thread> to #include "mingw.thread.h" in your code
3. If you aren't already you need to make sure that you define _WIN32_WINNT correctly. The easiest way to do this is via the gcc command line, eg add -D_WIN32_WINNT=0x0501 .
