Problem with gcc on HPUX11.11

Hi I'm new to this group, and if I'm at the wrong group or of topic I
apologize.
I have installed gcc4.1.1 that I've downloaded from the following link
"http://hpux.connect.org.uk/hppd/answers/4-5.html" with all the programs
mentioned on the page.
When I try to compile a simple program I get the following error

/usr/lib/dld.sl: Unresolved symbol: pthread_mutex_lock (code)
from /usr/local/libexec/gcc/hppa2.0w-hp-hpux11.11/4.1.1/cc1
gcc: Internal error: Aborted (program cc1)

Any help will be appreciated
Thank in advance

Can you do: chatr /usr/local/libexec/gcc/hppa2.0w-hp-hpux11.11/4.1.1/cc1
what /usr/lib/libc.sl

What version of HP-UX are you using, 11.11 should have the stubs.
There should be stubs in libc for pthread_mutex_lock.
The real version is in libpthread.

Hi Dennis thank you for the reply. I am using HPUX 11.i v1
Here is the output of chatr

chatr /usr/local/libexec/gcc/hppa2.0w-hp-hpux11.11/4.1.1/cc1

and this is the output of what /usr/lib/libc.sl

I don't know why cc1 thinks it needs pthread_mutex_lock but isn't linked
with libpthread?

You need a later version of libc. Eventually they added the pthread_*
stubs to libc.

Any libc patch from PHCO_23093 to the latest PHCO_34275, would have them:
( SR:8606102984 CR:JAGab69119 )
On HP-UX if a nonthreaded application links to a
thread-safed library the link will fail due to
unresolved symbols.To resolve these symbols, it is
necessary to link the nonthreaded application to the
threads library libpthread.But linking to that library
makes the application threaded even if it creates
no threads. Providing POSIX 1c thread "stubs" in HP-UX
C language library have two direct effects for
nonthreaded applications. a) POSIX 1c threads symbols
are resolved if a nonthreaded application links to a
thread-safed library
