How to use regex on I.MX RT1050

Hi,

I’m relatively new in MCUXpresso projects, I need help with regex in an I.MX RT1050 project.

I tried to include “regex.h” and use regcomp and regexec but when I try to compile the code I have this errors:

– undefined reference to `regcomp’
– undefined reference to `regexec’

Why MCUXpresso find the .h file but it don’t find the inplementation of the functions?

Thank you.
