 Posted: Mon Jul 26, 2004 6:42 pm Post subject: Error when porting from intel compiler to PGI compiler |
 |
|
Hello,
I am trying a demo version of the PGI compiler (vers5.2-1 on RedHat 7.2). The code I have to compile works perfectly using gcc or icc. With pgcc, I have got several errors:
1) PGC-S-0103-Illegal operand types for comparison operator
For example:
| Code: | #include <stdio.h>
int main(){
char c1;
c1='\0';
if( c1 == NULL ) printf ("hello");
return 1;
} |
It may not be regular ANSI C code, but still, it is widely accepted. I could fix that by changing the PGI stddef.h file, replacing #define NULL ((void *)0 by #define NULL 0.
2) PGC-F-0000-Internal compiler error. Macro recursion stack size exceeded
It happen for several functions of my program. Do you know a way to fix that ? |

The header files we have included have been only slightly modifed from the existing system include files. Looking at the stddef.h file, found on our RedHat 7.2 system in /usr/include/linux, I see that NULL is defined as "(void *) 0". Basically, we choose to accept the system's definition of NULL. As you pointed out, you can simply re-define NULL to suit your needs or you could cast the NULL to a char.
As for the ICE, could you send a more detailed description of the problem to trs@pgroup.com? From the error message it sounds like we're doing an infinite recursive macro expansion and might be a compiler bug.
Thanks!
