Customer gets the following error message when launching ANSYS90 in alpha tru64 5.1




410114:/ansys_inc/v90/ansys/bin/alpha/ansys.e90: /sbin/loader: Error:
libpthread.so: symbol "__atdlclose_mutex" unresolved
410114:/ansys_inc/v90/ansys/bin/alpha/ansys.e90: /sbin/loader: Fatal
Error: Load of "/ansys_inc/v90/ansys/bin/alpha/ansys.e90" failed:
Unresolved symbol name

What does he need to do to get ANSYS to run on this machine?

A: You can go into the directory:

/ansys_inc/v90/ansys/syslib/alpha/

Here, there is a file name libc.so.
It's the ANSYS file where the symbol "__atdlclose_mutex" is defined.
This symbol must be defined in the ANSYS library for the version 5.1 of tru64 but not for the version 5.1A of tru64.

If you rename libc.so to libc-old.so, ANSYS will take the system symbol definition.
You should now be able to launch ANSYS90 without the error message.
