Problems with kernel symbols in HP-IA 11.31

[Ravi K N]

One of our application that gathers kernel statistics by using 'pstat_getdynamic' system call is failing with the following errors. Does anybody has any clue?
Are there any changes to 'pst_dynamic' structure in HP 11.31.

What might cause following errors
----------------------------------------
Kernel symbol 'async_bufhead' not found
Kernel symbol 'ip_mib' not found
Kernel symbol 'tcp_mib' not found
Kernel symbol 'udp_mib' not found
----------------------------------------

This is URGENT, please help.

Thanks
Ravi.

I see no connection between pstat_getdynamic and those "not found" errors. Are you sure your application isn't calling nlist64?

Thanks for the quick response Dennis.

Sorry if i confused you, i am not a HP-UX expert.
I meant to say that when we invoke the executable we are getting errors saying kernel symbols not found. We make a call 'pstat_getdynamic' inside our code i thought whether somewhere it was causing the problem.

Please help us by explaining on what might cause "Kernel symbol not found" errors. Are we missing any package?

I am sure that our application is not calling 'nlist64'

Dennis,

I Just checked and found that we are using nlist64 in our code.
OS is HP-UX B.11.31 U ia64

Are there any changes to nlist64 in hp11.31?

I am urgently waiting for your reply.

Thanks

I said that didn't I? :-)

The variables you are searching for, no longer exist on 11.31.
$ elfdump -t /stand/vmunix | fgrep -e async_bufhead ...

Whatever you were doing with them, you'll have to remove that.
Your application is kernel intrusive and that isn't forward compatible.
