[Denemo-devel] Discussion of bug #24424

[Richard Shann]

I paste here Charlie's report on the bug tracker, so that I can comment
on it effectively.

> I've encountered a similar problem with Denemo 0.8.0FIX (which I

I think these may not be fatal, there are some modules not found on
working systems. Of course, they should be fixed.

This is fatal, it is the reason for setting GUILE_LOAD_PATH.

?? I guess you mean that someone reported LilyPond issuing this message
as well - the message comes from Guile, which LilyPond uses. It would be
caused by the guile code failing to find its initialization scripts. One
of the places it looks is in GUILE_LOAD_PATH if that is set.

??? Did you set it to the same thing as it was already set - if so, is
it a question of the variable not being set for the current user? You
can do something like

echo %GUILE_LOAD_PATH%
to find out what it is set to (I think).

Yes the pop-up is another problem.

It would be nice, but I think that is a Guile problem - whether Denemo
can put GUILE_LOAD_PATH into the environment under windows I am not sure
- gtk does have a gtk_setenv thing I think...
