Legacy ImageMagick Discussions Archive

I am using Centos 5. ImageMagick and Ghsotscript of this distribution is quiet old and a lot of PDF file can not be converted:

$ /usr/bin/convert -version
Version: ImageMagick 6.2.8 05/07/12 Q16 file:/usr/share/ImageMagick-6.2.8/doc/index.html
Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC
$ /usr/bin/gs -v
GPL Ghostscript 8.70 (2009-07-31)
Copyright (C) 2009 Artifex Software, Inc. All rights reserved.

Therefore I decided to install new versions from source:

$ /usr/local/bin/convert -version
Version: ImageMagick 6.7.9-9 2012-10-05 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC
Features: OpenMP
$ /usr/local/bin/gs -v
GPL Ghostscript 9.06 (2012-08-08)
Copyright (C) 2012 Artifex Software, Inc. All rights reserved.

Note, that /usr/local/bin is before /usr/bin in my PATH:

$ echo $PATH
/usr/local/texlive/2012/bin/i386-linux:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/linthal/bin

While the old versions could convert PDF files into JPG thumbnails, the new ones not:

$ /usr/bin/convert -thumbnail x500 /tmp/a.pdf -quality 50 jpg:/tmp/a.jpg
$ echo $?
0
$ ls -l /tmp/a.jpg
-rw-rw-r-- 1 linthal linthal 14613 Oct 9 10:11 /tmp/a.jpg

$ /usr/local/bin/convert -thumbnail x500 /tmp/a.pdf -quality 50 jpg:/tmp/a.jpg
convert: no decode delegate for this image format `/tmp/magick-wDO3Xgc0-00000001' @ error/constitute.c/ReadImage/550.
convert: Postscript delegate failed `/tmp/a.pdf': No such file or directory @ error/pdf.c/ReadPDFImage/679.
convert: no images defined `jpg:/tmp/a.jpg' @ error/convert.c/ConvertImageCommand/3044.
$ echo $?
1

Some information reegarding gs and ImageMacick compilation. At running confugure for ImageMagick I saw the following messages (note that I tried configure with and without "--with-gslib", the result is the same:

$ ./configure --with-gslib

The problem is solved for me so far, that I downloaded the pre-compiled version of ImageMagick for CentOS and it works correctly.
