I pulled down a device driver for a GPIB instrument (HP 4145) It requires a library called "formatio". Is this a National Instruments lib and, if so, is this available for Solaris?
It looks like you may have downloaded the LabWindows/CVI version of this driver. I noticed that there is a contributed version of the driver for LabVIEW (which I assume is the development environment that you are using) for the HP 4145B. That one may work for you, but since it is contributed there won't be much I can do if it doesn't.
Hope this helps.
