Here are some features about rt-thread c++11 threading futures.

  • Atomic.
  • Conditional variables.
  • Clocks.
  • Future.
  • Mutexes.
  • Threads.
  • TLS.

How To Use

Note that using C++ 11 in rt-thread requires modifying some of the files in the toolchain. Before modifying the tool, back up the tool chain.

  1. Enable c++11 support

  2. Download toolchain GCC 10.2.1:

    gcc version 10.2.1 20201103 (release) (GNU Arm Embedded Toolchain 10-2020-q4-major)

  3. Delete the following files:

    rm -f toolchain/arm-none-eabi/include/c++/10.2.1/thread
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/mutex
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/condition_variable
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/future
rm -f toolchain/arm-none-eabi/include/pthread.h

  4. Clear the contents of the following files and keep them to prevent compilation failures:

    toolchain/arm-none-eabi/include/sys/_pthreadtypes.h

  5. Update rtconfig.py file. add compilation parameters:

    CXXFLAGS = CFLAGS  + ' -std=c++11 -fabi-version=0 -MMD -MP -MF'
