3459.0. "non-inlined virtual member functions not defined" by BLAZER::MIKELIS (Software Partner's Eng. MR01-3/F26) Fri Feb 21 1997 10:52

I've got a customer who is experiencing the following errors while
linking a c++ 5.1 app. Is he missing some libs? /james


    Brief Description of Problem:
    -----------------------------

We're trying to link in code which using template-based classes
and it doesn't seem to be working.  The linker spits out a
lot of errors (see below).  We've had similar problems before
using HPCC (the HP c++ compiler) and we're able to solve them
by playing with the "ptrepository/defmap" file and some
command-line switches on the compiler.  Now, CXX seems to
create a "cxxrepository", but there is nothing in it.
Do you have any suggestions?

Thanks,
Bill Gulstad

This is what he's from a SETLD.  I suspect he is missing something.

Looks like they are confused about which compiler to use
and which version supports what.

We'll work this off-line

They're coming from the Rogue Wave Tools.h++ library
(notice the RW symbol in front). Are they undefined
symbols in librwtools.a or are they undefined in their
own object files (you can do an nm to see where they're coming
from)? Version 5.3 now has automatic instantiation, were
they using manual instantiation (-define_templates) before?
