Some symbols are defined by more than one library.
That sounds like a really bad situation.
One library is supposed to be a new improved
version of parts of the other library.
libraries.
My understanding is that when shared libraries are involved,
the rules can get complicated.
That I'm a newbie with these libraries does not help either.
I would like to discover which symbols came from which library.
What, if anything, is the incantation to do that?
Your question is not very clear. If you want to see the symbols in a
particular library, I think "nm" is the tool for that.
nm lists dgesv_ , the symbol that should bring in these libraries,
as undefined (U).
There is no other entry for it.
Symbols that dgesv_ should bring in are not mentioned at all.
Is this part of shared library magic?
If symbol fred is defined in library G as well as library in B,
I'd like to know which symbol my executable picked up.
nm does not do that.
