Using msgpack in embedded RTOS environment

[umanayana]

I would like to use msgpack in embedded RTOS environment. I have a few questions

1. I msgpack platform independent?
2. What porting requirements are there?

Is there anything else I should be concerned about?

1. I msgpack platform independent?

• msgpack-c requires C standard library.
• If you want to use C++ part, msgpack-c requires C++ standard library.
• Other system dependent library is wrapped by https://github.com/msgpack/msgpack-c/blob/master/include/msgpack/sysdep.h

2. What porting requirements are there?

• It isn't documented.
• Here is a list, maybe incomplete.
  • msgpack-c uses dynamic memory allocation. If you use C, you need to prepare malloc, free, and realloc. If you use C++, you need to define global new.
• In addition, it might be helpful: https://github.com/msgpack/msgpack-c/issues/369
