Unix - Undefined Symbol

We get this error message when trying to start IDEAS by

ld.so: Undefined Symbol: _phg_cpx_dummy_await_event

This is a Sun Sparc2 station.  Running Sun OS 4.1.1.
IDEAS is not the master series version.

Once this error message appears, computer just sits

Any help would be apprecieated.

first find out which dynamic libs are used in your executable:

    ldd IDEAS

Then search where the undefined symbol occours:

    foreach lib (<list of libs returned by ldd>)
      nm -gop $lib | grep phg_cpx_dummy_await_event

Maybe phg_ is a phigs graphics library call, and you have the wrong version of the library installed.

Try the previously suggested comment, but look for any phg_ references.

If there are some phg_ references then I would expect to find phg_cpx_dummy_await_event in that library or libraries.  If phg_cpx_dummy_await_event is not in that library or libraries, then my initial comment holds, maybe you have a mismatched version of the library installed.
I would guess that either your load sequence is wrong or that something is missing from LD_LIBRARY_PATH.  It may be a missing Phigs library file, although I suspect that the routine may be an SDRC plugin.

Sunos 4.1.1 is quite old now. Are you sure that this version of IDEAS is supported on that revision of the operating system?
