/usr/lib/dld.sl: Unresolved symbol: pthread_create (code)

[gopa haldar]

My application uses third party library like boost which uses libpthread to create threads.
And this application is working fine with HPUX version 11.23 but following error oocurrs during runtime in HPUX version 11.11.
/usr/lib/dld.sl: Unresolved symbol: pthread_create (code) from /opt/bst/lib/libboost_thread.sl

ABORT instruction (core dumped).

but before call boost API, if I create a dummy thread using pthread_create api then it is working fine for both HPUX version.

Please let me know the solution of this problem.

you need to install the updated patch .

dld.sl: Unresolved symbol: pthread_create /opt/bst/lib/libboost_thread.sl
>Please let me know the solution of this problem.

Your libboost_thread.sl has been compiled on 11.23. You can't run this shlib on 11.11. You must recompile your third party library.

There is NO such function as pthread_create on 11.11. It gets mapped to _pthread_create_system by header file magic.

I am using HPUX 11.11 patch version PHCO_30544

[gopa haldar]

Even it is not working with latest PATCH PHCO_38307

>Even it is not working with latest PATCH PHCO_38307, libpthread

Or course not. As I said above, what you are doing isn't supported.
Where did you get libboost_thread.sl?

Jupinder's suggestion only works if you don't have __pthread_create_system stub defined in libc.sl.

I have buit the boost library in hpux 11.23 system

>I have built the boost library on 11.23 system

As I suspected. Then you know your solution. HP-UX is only forward compatible and if you want to run on 11.11, you must built it there.
