[iolib-devel] compilation error

[Peter Keller]

Hello,

I'm *very* new to Common Lisp and have only just started understanding
how to use packages and asdf. I have a client/server application in mind,
of which I've already written a fair amount (using the asdf module system),
and I would like to use iolib to multiplex the i/o.

I'm using sbcl 1.0.18.debian on an ubuntu 9.04 x86 box.

I initially used asdf to set up iolib and it picked the iolib-0.6.0
package and downloaded/compiled a bunch of denpendencies.  There were
some problems compiling it concerning its dependencies, which I'm sorry
to say I did not record or what I did to get around them--but it had to
do with cffi-grovel not being a package asdf new about, and I believe I
had to install cffi by hand before iolib would finish compiling becaue
the grovel module was now part of the cffi.

So, I started looking around for an example for how to use iolib,
and found one online in the current sources for iolib called
echo-server.lisp. It took a while for me to realize that net.sockets in
the iolib-0.6.0 version was moved to iolib.sockets in the current sources, and
after noticing that some other API changes happened and whatnot, I removed the
iolib-0.6.0 site and system from my ~/.sbcl/{site,system} directory, removed
the asd file symlinks, and git checked out the head of iolib.

I put that checkout into the above mentioned place, hand set up the asd
symlinks, and tried (require 'iolib) again. 

This is what I got:

* (require 'iolib)

... compile lines ...

I don't know how to get around this error.

I apologize for my gross misunderstanding of how to do all of this. I'm in the
process of figuring it out.

Thank you.
