Using std::mutex with STM32H7B3I

[FMarr.2]

I got an error when try to use std::mutex, std::lock and similar.

There is a define _GLIBCXX_HAS_GTHREADS that prevents compiling of .

Is there a way to define it from compilation or an implementation of std::mutex in RTOS?

Hi @Community member​ ,

To allow the community to help you, you need to provide some more details:

• are you using an example available in STM32CubeH7 package? If yes, which package version?
• or may be you generate the code with STM32CubeMX? Please share the .ioc file in this case.
• which IDE?

This is the full project:

STM32CubeIde 1.5

All necessary files are included.

Thank you very much

Hello Amel NASRI,

thanks for your interesting in the problem.

I think my problem is:

I would like to use some funtionality, for example std::mutex. From standard namespace.

A mutex depends on the O.S. Can be implemented by mean of a semaphore for example.

For RTOS, it seems this implementation is not available or at least is protected by a define not defined.

Is it possible somehow to enable the implementation?

Someone did this job, https://embeddedartistry.com/blog/2018/02/01/implementing-stdmutex-with-threadx/

but for me is not clear how to fit in STM32CubeIde.

Best Regards
