Re: Plug-in architecture

[Paul Davis <pjdavis engineering uiowa edu>]

Now this is a bit odd.  I'm actually getting ready to start on a project 
that is almost exactly like this.  And my name is Paul Davis too.

Anyway, I've only ever used libdl for loading plugins.  Its worked 
fairly well for me.  Its a rather simple api and does wonders.  There 
are a few interesting issues while using it with C++ but nothing 
extremely difficult to overcome.

The header is dlfcn.h and the library is just dl ( -ldl ).  Check it 
out.  You can take a look at the

A good write up can be found here:
http://sources.redhat.com/autobook/autobook/autobook_158.html#SEC158

The only thing is that description uses the autotools building which I 
consider to be a thing of the past.  www.scons.org is a much better 
build package.
All of the setting up of automake and the other tools described in that 
book are replaced with a single line in scons.  Which makes me mighty happy.

This is how I plan to use plugins for my project.  Let me know if you 
have any luck with the glib stuff.
