Hello,
I use regular expression with my ESP32 board, it works well. But when trying to use the
code with my MKRZERO it fails during the linking. The decalarations as included with
#include <regex.h> where found but the implementation cannot be linked:
undefined reference to regcomp' ... regexec' ... `regfree'.
I hoped that using lregex as linker flag might help here but I don't know how to check this
out. Is there a way to use this in the MKRZERO? And how can I do this?
Best regards
Tobias
Just a thought.
You might have to use a regex specifically written for Arduinos; with the ESP32 it might already be an object file that needs to be linked and that object file does not exist for the Arduinos.
This might do the trick: Regexp - Arduino Reference. It's a library so it will be compiled and linking should not be a problem.
Thanks sterretje,
that is what I wanted to avoid. But seems to be the best solution. For that I had to learn the new syntax of the regular expressions. Did so this morning.
Never stop to develop yourself 
Best regards
