Hello dear Monks,

I have a script which needs Image::Magick for some functions but not all.

I'd like to disable these functions if Image::Magick is not installed

I tried to do something like :
pseudo-code

$is_magick = 0;

if ( is_installed Image::Magick ) { $is_magick = 1 }
[download]

and later

if ( $is_magick = 0 ) {

  print "Image::Magick functions disabled";
}
else {

  do stuff with Image::Magick ...
}
[download]

I found some post on perlmonks and other places but nothing works

stuff like

our $is_magick = 0;
eval 'require GD';
if ($@) {
  # problems with GD, fall back to non-GD
} else {
  # we have GD, go for it!
  $is_magick = 1;
}
[download]

or

our $is_magick = 1;
BEGIN {
  unless (eval "use Image::Magick") {
    $is_magick = 0;
  }
}
[download]

The first example didn't change $is_magick, the second one gives me an error 500.

How can do this ?

Thanks

Have a nice day !
