regular expressions with Nios

Hi, 

 

I wanted to use regular expressions with C or C++ for the Nios. 

My code gets compiled but the linker gives an undefined reference to regcomp and regexec. 

 

Doe anyone have a clue to solve this issue? 

 

thanks in advance

Did you include all the required headers ( e.g. regex.h, stdio.h, stdlib.h ) ?

It is not built into the precompiled newlib. That is the reason. For some reason I was even not able to compile it into a customized newlib. 

I used http://www.pcre.org/ and built it as a nios library.
