devLibOpt depends on devCommonGpib.o which is where the above symbols
can be found; you'll have to load that first if you want to do it this
way. If you don't need GPIB for your IOC at all though, you should be
able to load just the devOpt object files that your application needs
instead of the whole devLibOpt library.
However rather than loading them individually like this a much better
way to get all your device and record support code loaded is to link
them together into a single binary in one of your App/src directories
and load that file instead. Look at the makeBaseApp example application
for hints on how to do that.
