I'm not sure if building static on HP is something that ever worked. Did
I write something about that in the .../doc/README file? I don't remember.

What you're seeing is probably a method that's never used, so with
dynamic linking the linker never searches for it and generates no error.
With static linking, the linker has to find and bind everything that is
defined at compile time, so it barks about the missing implementation.
I'm not sure about this special case, but there is a technique to keep
the compiler from generating default constructors that involves defining
them private and not provide implementations. Maybe the HP static build
is not capable of handling such situations. Could be a different thing
in your case, though.

Anyway - do you have to build it statically? Building statically on HP
always generated a lot of trouble, so if you're not forced to have a
static build, just do it dynamically. Or move to Linux. EPICS won't
support HP much longer (way too much effort for way to few remaining users).

Hope this helps,
Ralph
