Hi, I have been using ImageMagick successfully for years with pre-built
packages (Perl and Magick) on both Slackware 10 and Debian Sarge AMD64.
I am currently trying to track down an unrelated problem on my server,
and as part of this process I am building my own Perl from source (first
of all on my dev workstation). I'm running Slack 10.1, 2.6.14 custom
kernel, and just built Perl 5.8.8 from source, likewise ImageMagick
6.2.9-2. All make tests run successfully on both packages.
But when I try using ImageMagick from the new Perl on this setup, I get
a segmentation fault on the Read statement. Here's a minimal case:
#!/usr/bin/perl -w
use strict;
use Image::Magick;
my $image = new Image::Magick;
my $read_status = $image->Read('image.jpg');
The Read statement is where is segfaults.
I don't really have any idea why this would be happening. I tried
reverting to my old Perl (5.6.1) and it then works ok. I built Perl
mostly using the defaults (no threads, dynamic loading, no shared libs).
The ImageMagick utilities seem to work - at least, 'display' does.
Any ideas how I can track down what's going on here? Or is this more
something that I need to ask over on the Perl group? Are there any
'tricks' I need to know about in the interaction between ImageMagick and
Perl? I don't see why all the PerlMagick tests would work ok, but not my
minimal program. This is what stumps me. Surely them succeeding would
mean that the basic interaction between ImageMagick and Perl is working
ok? How would they be any different from my minimal program?
I also removed my old version of Perl, just to make sure there weren't
any lib conflicts going on here.
I also tried compiling Perl 5.6.2 just to see if this was a problem with
later versions of perl, but the same exact thing happens.
Any advice, pointers or suggestions on how to track down where the
problem is would be much appreciated.
Thanks,
-Neil
