Re: Using regex on OS/X

[James Gallagher]

Hi,

Got the update... On linux (RHEL3) I had to add strcase to the 
modules/regex file under 'depends-on'.

On Mac OS/X 10.3 I get:

ld: Undefined symbols:
_re_compile_fastmap
_re_compile_pattern
_re_match_2
_re_search_2

I can get these errors to go away by commenting out the AC_DEFINEs for 
them in regex.m4. This fixes the problem on Mac OS/X and the hacked m4 
script also works on RHEL3.
