Why there's no debugger?

Why there's no debugger?

[Josef Wolf]

Hello,

I followed the suggestion from the info pages and put following into my
~/.guile file:

  (use-modules (ice-9 debugger breakpoints))
  (use-modules (ice-9 debugger breakpoints source))
  (use-modules (ice-9 debugger breakpoints procedural))
  (use-modules (ice-9 readline))
  (activate-readline)

But now I get following error:

  ERROR: no code for module (ice-9 debugger breakpoints)

Any ideas what causes this error?

BTW: This is with guile 1.6.7 as it comes with suse-10.0.

Which info pages were those?  The info for 1.6.7 does not mention
(ice-9 debugger breakpoints ...), because those modules are not
included in 1.6.7.

To do debugging with 1.6.7, you need to download and install the
latest guile-debugging tarball/.deb from
http://download.gna.org/guile-debugging/.  Please see the README file
there for an explanation of how guile-debugging relates to Guile CVS,
and for where to look for guile-debugging documentation.

(To confuse matters, the manual of recent Guile 1.8.x releases
incorrectly documents these features, which are not actually present
in Guile 1.8.x.  The manual should be fixed for the next 1.8.x release.)

It means what it says: there is no code for the module, i.e. no file
ice-9/debugger/breakpoints.scm anywhere in Guile's load path.

Thanks for the answer, Neil.  You are right, I read it on a guile 1.8
installation.  At the time I wrote the mail, I had 1.6.7 and I failed
to remember that I read it on the other box.  Sorry for the confusion!

I guess the debugging will be included in some future guile release?

No problem.  A lot of the confusion stems from my slowness working on
this, I'm afraid.

Well that's more likely than being in a past release. :-)

More seriously: I strongly want to get this area (debugging and Emacs
interface) to a state where it is complete (for the immediate use
cases that occur to me), coherent and fully documented; and I hope to
achieve that in the next few months.  Then we can look at what makes
sense in terms of releases.

Regards,
        Neil
