Hi,

I want to use std::mutex, std::lock, std::async and similar in my project

for CC3200. What library/header should I include so that the compiler sees

this type/functions.

Wait fro your reply.

Best Regards

Hi Fortunato Marrelli,

What compiler are you using? See this FAQ on which C++ standards are supported: e2e.ti.com/.../faq-compiler-which-c-standard-is-supported

It looks like std::mutex was added in C++11.

Best regards,

Sarah

Hello Sara P,

thanks for the reply.

I have to develop a project on CC3220S_LAUNCHXL. I am interested in use GNU CPP so I opened the sample project

i2copt3001_cpp_CC3220S_LAUNCHXL_freertos_gcc. As I can see it is C++ but if i declare a variable of type std::mutex it does not compile.

What am i missing? Some define? Some include?

Could you help me?

Best Regards

Hello Sarah P,

I found this interesting link.

https://www.codeproject.com/Articles/1278513/Cplusplus11-FreeRTOS-GCC

But for me it is a little bit complicated . Maybe for you it is easier to understand?

Regards

Features for concurrency are added to C++ by the C++11 standard. However, the full implementation of these features requires significant integration with an underlying OS or RTOS, such as FreeRTOS in your case. I am not aware of any documentation from TI which shows how to integrate these C++ features with FreeRTOS, or any other RTOS.

Thanks and regards,
