Hi guy,
I try to compile the myGrep.c program I found on Web at this site
http://linuxgazette.net/issue55/tindale.html
which uses regular expression and include regex.h.

I get the following message :

In file included from myGrep.c:11:
c:/djgpp/include/regex.h:17: syntax error before "regoff_t"
c:/djgpp/include/regex.h:25: syntax error before "regoff_t"
c:/djgpp/include/regex.h:66: syntax error before "regmatch_t"

In fact, when I go through regex.h, I get this :

/* Copyright (C) 1998 DJ Delorie, see COPYING.DJ for details */
/* Copyright (C) 1995 DJ Delorie, see COPYING.DJ for details */
#ifndef __dj_include_regex_h_
#define __dj_include_regex_h_

#ifdef __cplusplus
extern "C" {
#endif

#ifndef __dj_ENFORCE_ANSI_FREESTANDING

#ifndef __STRICT_ANSI__

#define _POSIX2_RE_DUP_MAX 256


typedef off_t regoff_t;


....

#ifdef __cplusplus
}
#endif


which means that if I don't define C++ I do not get regex declaration.
Does it mean that regex declaration is available only in C++ ?

The first declare error comes from typedef off_t regoff_t

Sincerly

Martin
