Compiler/66AK2H12: Using c++11 threads and synchronization primitives in compiler version 8.3.1

Tool/software: TI C/C++ Compiler

I downloaded compiler ver 8.3.1 for c6000.

I am trying to use std::mutex by including <mutex>

it seems to be not implemented.

when i look further into the code, i see that the reason is that

_LIBCPP_HAS_NO_THREADS is defined in "__config_site"

I also enabled multi threading option in the compiler settings.

So my question is: isn't mutex and all other synchronization primitives in c++11 implemented?

I didn't see specific mention of this under "Section 7.2 of the "TMS320C6000 Optimizing Compiler User's Guide"

Hello Shiran,

I have no experience with C6000,
however I would say that mutex and other OS primitives would depend on OS you use
(Integrity, Linux, SYS/BIOS or VxWorks) and
ARM Cortex-A15 or TMS320C66x cores you are programming.
Please, refer to your OS documentation.

Unfortunately, no. Please see the article C++14 Support for ARM, MSP and C6000 Compilers, and the section of the C6000 compiler manual titled Characteristics of TMS320C6000 C++.

Thanks and regards,
