I cant get Drakma to work on SBCL / Linux, but it does work on SBCL /
Mac.

I'm running SBCL as provided with Ubuntu 8.04, Hardy Heron

I installed Drakma as follows

(require 'asdf)
(require 'asdf-install)
(asdf-install:install :drakma)

I had to skip all the GPG checks, but otherwise everything seemed to
go well.

When I try to use it

(asdf:oos 'asdf:load-op :drakma)
(defpackage :drakma-user (:use :cl :drakma))
(in-package :drakma-user)
(setq *header-stream* *standard-output*)
(http-request "http://lisp.org")
; in: LAMBDA NIL
; (HTTP-REQUEST "http://lisp.org")
;
; caught STYLE-WARNING:
; undefined function: HTTP-REQUEST

;
; caught STYLE-WARNING:
; This function is undefined:
; HTTP-REQUEST
;
; compilation unit finished
; caught 2 STYLE-WARNING conditions

debugger invoked on a UNDEFINED-FUNCTION in thread #<THREAD "initial
thread" {A84D6F9}>:
The function HTTP-REQUEST is undefined.

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Exit debugger, returning to top level.

("bogus stack frame")
0]


The same process works fine on my Mac running SBCL 1.0.16

I'm probably doing something really stupid, but any advice, gratefully
received.

When loading drakma make sure there were no errors (check output messages),
and updating to latest versions solves a lot of problems in many cases.
Debian (which i run) is the ancestor of Ubuntu so they should be similar enough.

Thanks - that's encouraging.

I've looked through the output and there are no obvious errors that I
can make out.

I'm pretty sure that asdf-install is pulling the latest versions of
everything.

I have successfully installed hunchentoot via asdf-install and that's
up and working, which would suggest that several of the key libraries
are working fine.

I'm wondering whether there is some key platform shared library that
is missing, but tracking the problem down is proving to be a challenge
for my relatively lowly lisp skills.

just because you used asdf-install doesn't mean you have the latest versions.
asdf-install tends to pull out-of-date tarballs.
if you want the latest source code, you would be pulling directly from one
of the source code repositories. i'm running off the repositories, so our
software versions are a little different.

some things to check:
o are the permissions ok on the pulled files?
in other words, are they world readable, and the directories writable?
you didn't pull the files as root?
o are the source files being compiled? can you find the .fasl files?
i don't know where ubuntu sticks its .fasl files, but i can see my
.fasl files next to the .lisp files, in most instances.
o is the asd soft link set up between your asdf main repository and the
drakma/drakma.asd file? it's real easy to add if it's not there.
(you don't have to check this if you are sure that drakma is being compiled.)
o are you getting at least a page of compilation/load messages when
you load drakma?
o did you run the "find" command that i sent in the previous email,
and make sure the source code was installed?
o what version of sbcl are you running?
o does it look like the line endings are unixy?
od -a drakma/util.lisp | head -30
you shouldn't see "cr" at the end of lines (there should be one
or two newlines, "nl").

sometimes it's best to start with a fresh environment and retry all
over again. what i mean by that is, delete the .fasl files, reboot,
and start the drakma load over.

to clean old fasl files (assuming they were placed in your drakma directory):
find drakma -iname "*.fasl" -print -exec rm {} \;

if none of that was any help, there's always the drakma mailing lists.
you would want to first browse or search the drakma mailing list archives,
and then post further questions there if you didn't find what you were
looking for.

Thanks - Its all working now!

I uninstalled SBCL, deleted all FASL files and asdf directories and
reinstalled everything and now it works .. bizarre
