Re: call a function in a module

[Alan <alan signal11 us>]

While it's kind of hard to say exactly what the problem is without 
seeing more code in context, one thing to make sure you do when writing 
applications with plugins is to use the -rdynamic compiler flag when 
building the executable. This flag ensures that symbols are exported. By 
default, symbols are only exported from shared libraries.
