Programming

hi everyone !!!i hope that all the members are in good mood help me in my problem!!

when i'm trying to compile with gcc i got this problem:

Quote:
gcc -c -DLINUX -DUNIX_OPSYS -DDEBUG -I/home/oracle/Open2/COMMON/inc -I/home/oracle/Open2/dbg -I/home/oracle/Open2/syu/inc -I/home/oracle/Open2/syu/LGM/inc -I/usr/local/oracle/9.2.0/precomp/public -DLINUX -DUNIX_OPSYS -DDEBUG -I/home/oracle/Open2/COMMON/inc -I/home/oracle/Open2/dbg -I/home/oracle/Open2/syu/inc -I/home/oracle/Open2/syu/LGM/inc -I/usr/local/oracle/9.2.0/precomp/public -c -o su_lgm_lib_ctim.o su_lgm_lib_ctim.c
su_lgm_lib_ctim.c:39: erreur: conflicting types for ‘sys_errlist'
/usr/include/bits/sys_errlist.h:28: erreur: previous declaration of ‘sys_errlist' was here
make: *** [su_lgm_lib_ctim.o] Erreur 1
when i go to the code there is nothing unusual :

Code:

/****************************************************************************/
char *our_ctime(time_t t)
{
register char *p1, *p2;

p1 = p2 = (char *)ctime(&t);
while(*p1)
{
if (*p1 == '\n')
{
*p1 = 0;
return(p2);
}
p1++;
}
return(p2);
}
i tried to resolve this problem so i tried to go to the
/usr/include/bits/sys_errlist.h

and i open it but i didn't understand anything:

#ifndef _STDIO_H
# error "Never include <bits/sys_errlist.h> directly; use <stdio.h> instead."
#endif

/* sys_errlist and sys_nerr are deprecated. Use strerror instead. */

#ifdef __USE_BSD
extern int sys_nerr;
extern __const char *__const sys_errlist[];
#endif
#ifdef __USE_GNU
extern int _sys_nerr;
extern __const char *__const _sys_errlist[];
#endif
so i included the stdio.h in the file and nothing happen,i tried to use the -D OPTION to tell the complierv to use __USE_GNU

any idea for this problem!!

sys_errlist is already defined in something it included and doesn't need to be defined again in su_lgm_lib_ctim.c. They probably tried to avoid including anything that defined it, but somehow it did. Playing with -D won't stop your own code from defining something that already exists, and you shouldn't define GNU_SOURCE without understanding the effects it has anyway(lots -- it's saying "I use and want to use all nonstandard GNU extensions"). Nor will adding another header help when it's defined too many times already. Try just commenting out the line:

Code:

//extern char *sys_errlist[];
