/usr/lib/pa20_64/dld.sl: Unsatisfied code symbol 'pthread_create'

[Alaaeddin Ali]

Hi;

When i try to compile a multi-threaded Oracle Pro*C program, it compiles just fine. but in run time i get the following error:
/usr/lib/pa20_64/dld.sl: Unsatisfied code symbol 'pthread_create'

what could be the reason behind this ?

Hello Alaaeddin.
do a man pthread to see more information.

or check out the following link.

http://docs.hp.com/en/B2355-60130/pthread_create.3T.html

also check to see if this is not patch related or kernel paramter related.

Dear Fabian;
Thank you for your prompt reply.

The thing is that when i compile the source in a different machine, the program runs just fine. But for a specific machince it is giving the mentioned error. So just tell me whet is causing this problem; may be dld.sl is corrupted or need to apply some kind of Patch.

Hello Alaaeddin.
Then I would defenitely says that this is patch or kernel parameter related.

Check your /var/adm/syslog.log file to see if there is any error message there.

also run dmesg command.

Also remember to award points to the answers that given

There is no function pthread_create in older versions of libc and libpthread. Only when NxM threads were implemented did it exist. So you need to install a newer libpthread. (Calls to pthread_create were resolved to a static function in .)

>Fabian: kernel parameter related. Check your /var/adm/syslog.log file to see if there is any error message there. also run dmesg command.

None of these will help with a missing patch.
PHCO_29960 is the recommend one for 11.11.
