Programming

Hi,
I am trying to get a the process cpu usage from the /proc file recently, on the Solaris 5.10. But met some rookie issue which i need some help. for below program, compiler complains that pstatus_t is undefined, although both type are defined in the procfs.h.

#include <sys/procfs.h>

int main()
{
struct pstatus *pstatus_p;
pstatus_t *pstatus_p2;
}

Errors as below:
$ cc pstatus.c
"pstatus.c", line 6: undefined symbol: pstatus_t
"pstatus.c", line 6: undefined symbol: pstatus_p
cc: acomp failed for pstatus.c

$ gcc pstatus.c

I can sure that the cc and gcc works fine with other programs. Would you please take a look at this issue and provide your suggestion. Thanks in adv.

got some more information: even i commented out the include line, the compiler won't complain with the first line, i.e. "struct pstatus *pstatus_p;".
I suppose it is mean that the files does not be included at all. But the file is right under the /usr/include/sys directory.

Anyone knows why? or how should i investigate it more?

seems that
cd /usr/local/lib/gcc-lib/sparc-sun-solaris2.10/3.3.2/install-tools
../mkheaders

can fix the gcc issue.

Looks like the following may be your problem with the procfs header:

Code:

#if !defined(_KERNEL) && _STRUCTURED_PROC == 0
#include <sys/old_procfs.h>
#else   /* !defined(_KERNEL) && _STRUCTURED_PROC == 0 */
.....
#endif

Thanks Murphy.
Do you mean that the old_procfs.h file raises the issue? Could you please present it a little more detail?

Sorry for responsing a little bit late
