 how to deal with stdlib.h when i compile my project today,gcc report the error as follow:
In file included from /usr/include/bits/string2.h:1176,
from /usr/include/string.h:360,
from /home/source/include/port.h:53,
/usr/include/stdlib.h:527: parse error before `('
/usr/include/stdlib.h:529: parse error before `('
the 512 line of /usr/include/stdlib.h is
/* Allocate SIZE bytes of memory. */
extern void *malloc (size_t __size) __THROW __attribute_malloc__;
/* Allocate NMEMB elements of SIZE bytes each, all initialized to 0. */
extern void *calloc (size_t __nmemb, size_t __size)
__THROW __attribute_malloc__;
pls tell me what is lead to occuer this problem

Are you sure you don't mean 527th?

There is no problem with this line /per se/, provided the reserved
keywords __THROW and __attribute_malloc__ decode to something your
implementation understands.
Then again, perhaps that's just the problem: are you sure you're using
the right header files with the right compiler?
Alternatively, something may be wrong on the lines before these. But I'd
be wary of messing with the implementation's Standard header files -
better check and make backups before you change anything.

The problem is unlikely to be with your headers, unless you have been
messing with them. It's more likely to be a problem with your source
code, which we can't see. Even if it is a problem with your headers,
showing us lines 512-516 of your header won't help us to help you if the
compiler reports that the problems are on lines 527 and 529.
My guess - your source code called a macro, but the call is wrong.
Solution: fix your code, or present to this newsgroup the smallest
compilable program that exhibits the problem.

And show us the exact compilation command that produced those
diagnostics.

9999 times out of 10000 this problem is absolutely nothing to do wth
the standard header.
Check your own code just before and just after you #include stdlib.h,
especially any nonstandard headers. I bet you find a missing
semicolon, nor missing definition of some type.

my project is a very great,it was planed to compile on redhat6.2.but
now i compile it on redhat7.2 and the gcc's version is 2.96!
ofcourse my /home/source/include/port.h:53 is :
#include <string.h>
when occuer this problem, it seems to me that stdlib.h must be is
right,but the 527 is :
* Allocate SIZE bytes of memory. */
extern void *malloc (size_t __size) __THROW __attribute_malloc__;
/* Allocate NMEMB elements of SIZE bytes each, all initialized to 0.
*/
extern void *calloc (size_t __nmemb, size_t __size)
__THROW __attribute_malloc__;
,so i think in my project there must be a header file with a declare
of function malloc,i 'grep -rn '\*malloc' /home/source',the result is
home/source/lib/iq_1/iq_ytab.c:772: extern char *malloc();
home/source/Util/imake/imake.c:773: char *p, *malloc();
as you have seen ,there no defiune of function malloc.
thanx any quick respones

You shouldn't be using gcc 2.96. See this URL:
http://gcc.gnu.org/gcc-2.96.html
If possible, I recommend you upgrade to a less broken gcc (and
possibly glibc?)

You really shouldn't be declaring malloc that way. You're telling
the compiler there's a function called malloc which returns char *,
but the function in the standard C library returns void *. I'm not
sure if this is the cause of your problems or not, though.
If you #include <stdlib.h>, you won't have to provide your own
declaration of malloc.
