[Corelinux-develop] default library loader and library instance

[Christophe Prud'h. <pru...@MI...>]

I think that we should rely on libtool for the default implementation.

I mean that the library to be loaded may have the following
name "plugin" and the real name(built internally) is "libplugin.la" which 
is a file generated by libtool. this file contains informations about 
dependencies. 

Loading a .so is ok but the dependencies won't be met automatically so you 
have to do it "by hand" which is boring and ugly.

From my experience of loading c++ libraries, you provide a c function with 
"C" external linking:
the developper of the library "plugin" has to provide something like

extern "C" {
  void* init_plugin()
  {
    return new plugin;
  }
}

Moreover what about library destruction?
what if the library loader is destroyed while some libraries are still loaded?
will we use some kind of reference counting to keep track of the libraries 
which are loaded
 - +1 when the library sends a message that the object has been created  
successfully
 - -1 if destroyed
that is we should implement some kind of event notification system
(mediator/observer?)

thoughts?

As you may have noticed, I am willing to do the default library 
implementation :). I would like to have it working as quickly as possible.

C.
