Problem including regex.h from newlib (IDFGH-1155)

[ivanO86]

Hi,

I am trying to validate some regular expressions and I found the regex library into the newlib include folder. When I try to include this header in my code, I have some unknown type errors:

~/esp-idf/components/newlib/include/regex.h:43:1: error: unknown type name 'off_t'
typedef off_t regoff_t;

Also I have tried to find the regex symbols into the newlib build directory but I couldn't find anything.

Can we use this library? Am I missing any link flags or something like that? I use the time.h and works properly.

Regards.

Hi,

thanks for the comment. I have added this header, but I still having problems with the linker.
undefined reference to regcomp' undefined reference to regexec'
undefined reference to regerror' undefined reference to regfree'

I am using this library in my own component and I don't know if I am missing some linker flag, but I cannot find these symbols in the newlib build folder.

regards.

Ah OK sorry don't know if the library was built with that option, probably too bloated. You may want to look at the regex engine from the micropython project.
