[wxperl-users] wxDemo bug report - not use-ing Class::Accessor::Fast

[Nick J. <nic...@gm...>]

Mattia,

Not sure if you prefer bug reports on the list or via the bug tracking
system. the wxDemo code in CVS has a very minor bug (in lib/Wx/Demo.pm).
Line 12 is:

use base qw(Wx::Frame Class::Accessor::Fast);

The demo doesn't run and there's a fatal error because Class::Accessor::Fast
isn't use-d. Putting

use Class::Accessor::Fast;

before the 'use base' line fixes the problem. I spotted the bug in Mark's
excellent wx Bundle (http://www.gigi.co.uk/wxperl/ppm.html), but since it's
still in CVS HEAD I thought I'd report it here.

Thanks,


Nick

Hi Nick,

There is something else happening here.
The demo stuff works for me as is.

A quick check in the perldocs confirms that just having
use base qw(Wx::Frame Class::Accessor::Fast);

should work OK without any need to 'use'.

It would be interesting to know what's causing it to fail on your
machine. What error message do you get?

It works here on ActivePerl build 817, Class::Accessor version 0.26

Regards

Mark

Sorry, user error. I didn't have Class::Accessor::Fast installed so I
got the message:

Base class package "Class::Accessor::Fast" is empty.
  (Perhaps you forgot to 'use' the module which defines that package first.)

I added the 'use', which got rid of that error, but then complained
that Class/Accessor/Fast.pm couldn't be found in @INC, so I suppose I
assumed that the lack of 'use' was an issue. (Though I did think it
was a bit un-Perlish.)

Thanks, and sorry for wasting your time,

Nick
