Re: glade2perl: Does it work? (And some more on glade in general)

[Toralf Lund <toralf kscanners com>]

OK. I finally got around to testing this again.

First of all: I now get the following warning when I generate source code:

Tue Feb 29 09:30:05 2000 Gtk-WARNING **:
/usr/lib/gtk/themes/engines/libbuffy.so: undefined symbol:
gtk_style_apply_default_background at
/usr/lib/perl5/site_perl/5.005/Glade/PerlGenerate.pm line 161.

I also got the following message once, but I'm unable to reproduce this now :

 Glade::PerlGenerate::Form_from_Pad_Proto('Glade::PerlGenerate',
'Glade::PerlProject=HASH(0x851d2a8)', 'HASH(0x8493868)') called at
/usr/lib/perl5/site_perl/5.005/Glade/PerlGenerate.pm line 79
 Glade::PerlGenerate::Form_from_Glade_File('Glade::PerlGenerate',
'glade_filename', '/usr/work/sys/src/gnome/launch/launch.glade') called at
/usr/bin/glade2perl line 30

I don't remember if I saw this earlier.

Secondly, I had set source directory to '.' in "project options", but this
caused the following error message to occur (this was after I figured out the
correct way to execute the application and how to avoid the message about
gnome.pm):

% perl -e 'use launch; launchMain->run'
syntax error at launch.pm line 31, near "use ."
BEGIN failed--compilation aborted at -e line 1.

I have now changed source directory to "perllib"

The error message was:

Can't locate gnome.pm in @INC (@INC contains:
/usr/local/lib/perl5/site_perl/linux /usr/local/lib/perl5/site_perl
/usr/lib/perl5/5.00503/i386-linux /usr/lib/perl5/5.00503
/usr/lib/perl5/site_perl/5.005/i386-linux /usr/lib/perl5/site_perl/5.005 .)

but it turns out that this was caused by something different from what I
expected, see below.

Right. I can actually see my window now, although I also get a warning about
apply_default_background when I start the application. My command and output
are included below.

% perl -e 'use perllib::launch; launchMain->run'
Tue Feb 29 10:01:45 2000 Gtk-WARNING **:
/usr/lib/gtk/themes/engines/libbuffy.so: undefined symbol:
gtk_style_apply_default_background at perllib/launchUI.pm line 98.

It would be nice with correct documentation, though, as the the lack of it
limits the usefulness of the whole package a lot. And of course, incorrect
documentation is worse than no documentation.

I'll try this earlier.

I see. I had included a '-', with the magical word 'gnome' in front of it,
which was the cause of a lot of my problems. Apparently all the noise about
gnome.pm was a result of this!

I don't bother to include them now, as everything works fine.

Thanks for your help.
