ichimunki has asked for the wisdom of the Perl Monks concerning the following question:

I have followed the technique from this discussion and gotten Perl-Qt to compile and install with Qt-2.3.0, however when I go to run the tutorials I get the following error: 
Can't locate object method "new" via package "Qt::Application"
(perhaps you forgot to load "Qt::Application"?) at t1 line 3.

I've tried various requires, uses, and imports but this error won't go away.

The whole module is compiled C++ code or I would be inclined to try and peek at the source before asking but I don't read C++ yet. Can anyone offer insight as to what is going on here?

    This error message is typical when you forget the appropriate use statement. I'd expect a she-bang line on line 1, use strict on line 2, and use Qt (or some other Qt) on line 3, and then you wouldn't have a new on line 3. ;-)

    But without seeing the code, this is just guessing.

    I had the same problems running the tutorials after fighting to get the code to compile. Here's what I found: QtPerl works fine on my Mandrake 7.2 box using Perl 5.6.0, Qt 2.2.1 and gcc 2.95.3. However, on Mandrake 8.1 with Perl 5.6.1, Qt 2.3.1 and gcc 2.96 it gives the Can't locate object method "new" via package "Qt::Application" error on running any PerlQt app.

    I copied the Mandrake 7.2-statically-compiled module over to the Mandrake 8.1 box, but running PerlQt apps still resulted in the same error.

    What's your code look like?
[reply]
      The first tutorial (this is included in the module tarball) is a simple hello world (and this I can't get to run): 
      #!/usr/bin/perl -w
use Qt 2.0;
import Qt::app;

$hello = Qt::PushButton->new('Hello World!', undef);
$hello->resize(100, 30);

$app->setMainWidget($hello);
$hello->show();
exit $app->exec();

      I suspect this is more of a technical difficulties issue, FYI: the machine is a 586 running Debian main, Perl upgraded to 5.6.1 and the Perl-Qt is the latest tarball from CPAN.
