Hi,

I use Visual Studio 2022.

When I include pthread.h file, following error occurs.

I installed vcpkg but the same error occurs.

Hello @DONG KYUN AHN ,

Welcome to Microsoft Q&A forum.

Please try to close VS 2022 and run vcpkg install pthreads:x64-windows in an elevated Command Prompt. After that, launch VS and open your project, include pthread.h file again.

Sincerely,

Tianyu

Hi,

When I input the command after close VS2022, debug window shows below message.

However the problem still occurs. How can I resolve the problem?

After installing pthread, the location of pthread.h is ........\AppData\Local\vcpkg\archives\2d\app\include\pthread.h.

I registered the path in Visual Studio2022.

In the path, I made app directory and unzipped 2d18a12b666788cecf27ac6b37f5e57ae0fc1baae81cb62c395641347f156b19.zip file in ........\AppData\Local\vcpkg\archives\2d.

Hi @DONG KYUN AHN ,

On my side, I just done following steps:

Go to https://github.com/Microsoft/vcpkg => download the ZIP folder => extract the ZIP folder => open it and run the bootstrap-vcpkg.bat file.

Run CMD(not PS) => run cd XXXXX command to redirect to the directory(the same folder with bootstrap-vcpkg.bat file) where vcpkg.exe file stored => run following commands one by one => vcpkg install pthread, vcpkg integrate install and vcpkg install pthreads:x64-windows.

No other configurations to set/register, and the pthread.h file is included successfully.

I recommend reinstalling pthread by following above steps and check again.

Feel free to let us know the results.

Best Regards,

Tianyu
