pthread problem on itanium

Alok Chugh — Mon, 03 Oct 2005 05:35:54 GMT

Hello,

I am facing a problem in my code while migrating to HP11iv2 Itanium env. On a pthread_create() call I get the return value 251. And the desired thread fails to spawn. Could somebody help me out on this. What could be the problem missing patch etc.?

Thanks very much,
Alok

251 error is nothing but,

#define ENOSYS 251 /* Function not implemented */

Did you include -lpthread library during compilation??

hth.

The OS error 251 is as follows.

#define ENOSYS 251 /* Function not implemented */

what are you kernel settings for max_thread_proc and nkthread??

Similar problem,

It is better to post this question into cxx-dev list sponsored by HP.

Hi,

Thanks for the reply. The kernel parameters for my system are :

max_thread_proc - 3000
nkthread - 8416

The link line for generating the shared library is :

/opt/aCC/bin/aCC -b +DD64 -AP -DPTHREAD_COMPAT_MODE -Wl,+e,AgentApi_I
nit, -Wl ,+e,__StaticCtorTable_Start,+e,__ZStaticCtorTable_End,+e,__StaticCtorTable_End,+e,__ZStaticCtorTable_Start,+e,_shlInit -o mylib.so AgentAPI.o WinRegistry.o AgentConfig.o -lstd -lstream -lCsup -lunwind -lm -lnsl -lpthread

Do you see something fishy here..

Thanks very much,
Alok

I dont see anything fishy out there. As i said, HP's C++ dev-list is most active and you can get good answers' there.
