There should be no problem calling gversion with GLX. However, there was
a very old bug were calling gversion before the forks done in pfConfig()
could cause strangeness, and I even now recall seeing it crop up with GLXLink.
The fix was to call it after the pfConfig(), and this bug did get fixed in IRIX5.
Are you running 5.0.X or 5.1?

->Any help?

We use the font library for our GUI in libpfutil and have no problems in
being MP or running under GLX in both IRIX4 and IRIX5.
Are you making all fm calls from the draw process, or are you using the
font manager in other processes to?
Do you only call fminit after pfConfig(), or do you ever call it before?
