Hi Everybody,
I'm trying to build a module for submission to CPAN. When I use
Build.PL, the module builds without any problems (as far as I can tell
:-)), BUT... when I use Makefile.PL I get the following message:
(/home/james/Gtk2-Ex-MindMapView-0.0.1)> perl Makefile.PL
Version string 'undef' contains invalid data; ignoring: 'undef' at
/usr/lib/perl5/5.8.8/ExtUtils/MM_Any.pm line 1307.
Writing Makefile for Gtk2::Ex::MindMapView
my simple Makefile.PL is as follows:
(/home/james/Gtk2-Ex-MindMapView-0.0.1)> cat Makefile.PL
# Note: this file was auto-generated by Module::Build::Compat version 0.03
use ExtUtils::MakeMaker;
WriteMakefile
(
'PL_FILES' => {},
'INSTALLDIRS' => 'site',
'NAME' => 'Gtk2::Ex::MindMapView',
'EXE_FILES' => [],
'VERSION_FROM' => 'lib/Gtk2/Ex/MindMapView.pm',
'PREREQ_PM' => {
'Test::More' => 0,
'Gnome2::Canvas' => 0,
'version' => 0,
'Graph' => 0
}
)
;
and the version info in MindMapView.pm is as follows:
(/home/james/Gtk2-Ex-MindMapView-0.0.1/lib/Gtk2/Ex)> cat MindMapView.pm
| head
package Gtk2::Ex::MindMapView;
use version; $VERSION = qv('0.0.1');
use warnings;
use strict;
use Carp;
use Gnome2::Canvas;
as far as I know about the module building process (which is very little
at this point), everything looks OK. What am I missing?
I can't reproduce here. Does 'lib/Gtk2/Ex/MindMapView.pm' contain the
string $VERSION anywhere else in the file? I doubt that's the problem
here though because this looks like an error from version/vxs.
I used Module::Starter to make a little 'Foo' distro.
Foo.pm
package Foo;
use version; $VERSION = qv('0.0.1');
1;
Makefile.PL
use ExtUtils::MakeMaker;
WriteMakefile(
'PL_FILES' => {},
'NAME' => 'Foo',
'VERSION_FROM' => 'lib/Foo.pm',
)
with:
perl 5.8.7
ExtUtils::MakeMaker 6.30
version 0.57
But, it works fine for me. Can you provide a minimal test case that
exercises the problem?
Randy.
