Change syntax of a declaration

[gregor weertman]

Hello,

I’m trying to compile Zabbix on HP-UX not disturbed by any knowledge of c.

The syswait.h gives an error when I compile it with gcc.
(Zabbix has to be compiled with gcc in my case)

The line on which the error occurs is:

extern struct syswait syswait[];

the error message:
error: array type has incomplete element type

seems like an syntax error.

When I put the line in a simple C program and compile whith cc
It compiles ok.

Can I change the syntax of that line for compilation whith gcc?

You should really use the home forum for this kind of question.

http://www.zabbix.com/forum/

That is after all where you will find the highest concentration of people with the most knowledge about the software.

> [tt]extern [red]struct syswait[/red] syswait[];[/tt]
The problem is that so far the compiler has only seen
[tt]struct syswait;[/tt]
that is, it knows a structure with that name exists somewhere.

What the compiler hasn't seen, but needs is
[tt]struct syswait {
/* members of struct */
};[/tt]

Thanks for your responce.
THe call is already a few weeks on zabbix.

no answer yet.

Your explination helps so far that I copied a peace of code from sar.h to sysinfo.h

/* begin sar.h copy */
struct syswait {
long iowait;
#ifdef __LP64__
uint32_t pad[6]; /* long is 8 bytes on LP64 */
#else
uint32_t pad[7]; /* Fill to max cacheline (32) */
#endif
};

/* end sar.h copy */

extern struct syswait syswait[];

now there are no compilation errors and the appication runs.
however it is not communicating with the zabbix server.

Your explination however brought me a little in the right direction.

THANKS!
