Re: how to NOT export symbols in statically linked 3rd party shared libs

Thank you, Andrew,

actually, I figured that out after I sent this question to the ML.
However, the next question, which seems to be the core of the problem
arises:
What I really want to make sure is that at runtime, local symbols (the
ones not exported) will have precedence over exported (colliding)
symbols of other libs.

Is that the case?

Thanks again,

Chris
