>Description:
jpararas@tango ~ >gcc -v
Reading specs from /usr/local/gcc303/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.0.3/specs
Configured with: ../gcc-3.0.3/configure --prefix=/usr/local/gcc303 --with-gnu-as --with-as=/usr/local/bin/as --with-ld=/usr/ccs/bin/ld --enable-threads=posix
Thread model: posix
gcc version 3.0.3


This was compiled with thread support.  However, a simple
Hello World app, Foo.cpp fails to link, as follows:

jpararas@tango ~ >g++ Foo.cpp
/usr/ccs/bin/ld: Unsatisfied symbols:
   pthread_once (code)
   pthread_key_create (code)
   pthread_setspecific (code)
   pthread_mutex_unlock (code)
   pthread_getspecific (code)
   pthread_mutex_lock (code)
collect2: ld returned 1 exit status


And even:

jpararas@tango ~ >g++ -threads Foo.cpp
/usr/ccs/bin/ld: Unsatisfied symbols:
   pthread_key_create (code)
collect2: ld returned 1 exit status

A precompiled, single-thread gcc 3.0.1 (binary from HP)

jpararas@tango ~ >gcc -v
Reading specs from /opt/gcc/lib/gcc-lib/hppa2.0n-hp-hpux11.00/3.0.1/specs
Configured with: ./configure  : (reconfigured) ./configure  : (reconfigured) ./configure  : (reconfigured) ./configure  : (reconfigured) ./configure 
Thread model: single
gcc version 3.0.1

compiles & runs fine:
jpararas@tango ~ >g++ Foo.cpp
jpararas@tango ~ >./a.out
Hello world
