C++ support on NRF9160

[nicolae.georgescu]

Hello,

Does nrf9160 support C++? If it does, which version?

I saw a similar question over 2 years ago in which C++ was not recommended (https://devzone.nordicsemi.com/f/nordic-q-a/54056/c-in-nrf9160). I wonder if anything changed and if there is any sample with cpp.

Thanks

GCC support full C++17.  However SES strip C++ supports out of its gcc version.

Hi,

Yes, the nRF Connect SDK supports C++. The support has improved over time and currently C++ is also used within the SDK (specifically by the OpenThread and Matter implementations). C++11 is the default configuration but you can change this if you want another C++ dialect (98, 11, 14, 17, 2a, 20, 2b). For instance, if you want to use C++ 17 you use CONFIG_STD_CPP17. Please not that not all C++ features are supported, see C++ Support for Applications.

Thank you for the info and link! So Zephyr is the OS running on the 9160 module and DK, and it does offer C++. I saw the C++ sample now.
One more question: is there any difference between using Segger and VS Code in terms of C++ options? Or it's unrelated to the IDE?

Thanks

In principle there is no difference between using VS Code or west directly, or using Segger Embedded Studio Nordic Edition with NCS. However, with Segger the build process is a bit different and there are some bugs that are only seen when using Segger. Generally I recommend using VS Code or command line unless you are very invested in using Segger.

Note that when building C++ application that uses the standard library you need some more configurations than what is demonstrated in the C++ Synchronization sample, as described in this post.
