[Info-vax] Linking problem with multiply defined symbols, how to resolve?

[Richard Levitte]

Hi all!

I have this problem, that I want to build an app or a shareable image, which is linked with another shared library, but which also implements its own variant of symbols that are defined in that other shared library.

This is intentional.  It works absolutely fine to do this on the Unixen I've access to, as well as on Windows...  but VMS fails me.

Is this at all possible, or must I seek another method to get what I want?
(there is the possibilty to link with a .OLB library instead of a shareable image, but I'd like to explore the possibilities a little more before I resort to that)

An example below.  legacy-dso-legacyprov.OBJ defines all the ERR symbols that LINK complains about, and they are also defined by OSSL$libcrypto03_shr.EXE.
