What are the minimal Flash and RAM sizes to support c++ coding?

[DanielDuan277]

Hello!

I am now using NRF52833 and planning to use C++ for application-level programming.

Seems I have to include the full-featured c++ standard library, because I may need the following in c++;

1/ Containers: such as vector/queue/unordered_map, etc.

2/ Basic functions: sort()/accumulate(),etc.

3/ virtual table.

4/ Inheritance.

The question is: how many kB will be added to the Flash and RAM, to add the c++ library?

Thank you so much.

Hi,

The short answer is that we don't have support for C++ in NCS (with the exception of Matter samples) and it is up to the users who wants to use anything other than C to implement the support for it. I recommend you to have a look at  nRFConnect Examples fail to build with C++17  which discusses challenges with adding C++ support as well as addresses that we don't have C++ support in NCS. If you want to use the pure Zephyr SDK instead and add/use C++ there, we recommend you to reach out to the Zephyr project community on Discord. You will find a link on https://www.zephyrproject.org/

Kind regards,
Andreas

Hi Andreas,

Thanks for your reply.

I will reach out for Zephyr support on this question.
