Experimental Physics and Industrial Control System
Hi Ben,

No, Cygwin builds with SHARED_LIBRARIES=YES on 3.14.12.5.
I think the problem in your code was related to the following
#ifndef prim_types_GLOBAL
epicsShareExtern
#endif
epicsShareDef const char *prim_type_name[]
So if prim_type_GLOBAL is defined then the epicsShareExtern is not added to the definition. That is the problem. It always needs to be added, and the difference between importing and exporting the symbols is controlled by whether epicsExportSharedSymbols has been defined before that statement.
Note that I don't think the epicsShareDef is really not needed, that is currently only defined to anything on VAXC!
Mark
