Which compiler do you use? And how did you try to compile the adasockets
library. There is a mailinglist for adasockets here:

http://www.rfc1149.net/devel/adasockets

you will probably get more help there.

  That looks more like a gnatbind message.  Are your directories and
Path's set up so it can find the relevant libraries?
  If you tried Claw, did you run one of its mk*.bat files successfully?
Did you try one of the Notify or Simple Web Server or Finder examples
with success?

There are some excellent simple examples with the adasockets package
which although appear a bit hairy at first, they do explain how
adasockets can be used.

If you want some more complicated examples using tasking and protected
objects to store messages coming in, and sending them out, then email
me, but first I would recommend getting to grips with the examples
first.

I would also take a look at the distributed annex Gnat-Glade as this
is quite useful too.

AWS is a good candidate here too. It uses tasking, protected objects, buffered
sockets IO...
