rand() function in NCS

[Nhuan]

Hello everyone,

How can I use rand() and srand() functions in NCS?

I have already #include <stdlib.h>, but I got this issue:

undefined reference to `srand'

Thanks,

Hi 

By default Zephyr only includes a very limited set of the standard C libraries, as detailed here. 

If you set CONFIG_NEWLIB_LIBC=y in your project configuration you should get access to the full version of the standard C libraries.

Thank you very much, it worked for me.
