[Chicken-users] Can't import iup-web

[Matt Gushee]

Hello all--

I am trying to learn to use the IUP egg, and was working my way
through Juergen Lorenz's tutorial (thanks for that, BTW). Everything
went fine until I tried to load the 'inspector.scm' example--I got an
error indicating that iup-web could not be imported. Here's an example
of what happens:

I'm afraid I don't understand very well how to interpret chicken error
messages, but I investigated a couple of guesses as to the nature of
the problem, and found:

 * Was there a problem w/ the installation of the iup egg? I
   reinstalled it with

      chicken-install -debug iup

   but there were no error messages.

 * Was there something wrong w/ the iupweb shared library? I downloaded
   the IUP examples collection from Tecgraf. The following:

     gcc -o webbrowser webbrowser.c -liup -liupweb

   worked w/o errors, and produced a fully functional if minimal web
   browser.

So I have no idea what else could be the problem.

I have Chicken 4.7.0 and IUP 3.5.4 on Arch Linux (recently updated).

Any help would be much appreciated.
