CentOS

Hi guys,

I've been searching for a long time now on how to fix my convert command. It was working and stopped about a month ago.. I've found a confirmation of the problem at the [url=https://access.redhat.com/knowledge/solutions/72303]redhat site[/url] but you need a subscription to access the solution.

Enviroment:

- ghostscript-8.70-14.el5
- ImageMagick-6.2.8.0-12.el5

Here is how to reproduce:

[code][root@ home]# convert test.ps test.png
Error: /undefinedfilename in (72x72)
Operand stack:

Execution stack:
%interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push \
--nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push
Dictionary stack:

If anyone can help I would be very grateful.

Here is the Resolution from the RedHat Knowledgebase:

Resolution
As a workaround, please revert back to ImageMagick-6.2.8.0-4.el5_5.3. A permanent solution is currently under investigation.

I have the same problem and will be trying this soon.

Yes, I can confirm that installing ImageMagick-6.2.8.0-4.el5_5.3 from the CentOS 5.7 tree fixes the immediate problem

Thanks heaps guys!

For anyone else with this issue I did the following to resolve it:

[code]cd /usr/src
wget ftp://fr2.rpmfind.net/linux/centos/5.7/os/x86_64/CentOS/ImageMagick-6.2.8.0-4.el5_5.3.i386.rpm
wget ftp://fr2.rpmfind.net/linux/centos/5.7/os/x86_64/CentOS/ImageMagick-6.2.8.0-4.el5_5.3.x86_64.rpm
wget ftp://fr2.rpmfind.net/linux/centos/5.7/os/x86_64/CentOS/ImageMagick-devel-6.2.8.0-4.el5_5.3.i386.rpm
wget ftp://fr2.rpmfind.net/linux/centos/5.7/os/x86_64/CentOS/ImageMagick-devel-6.2.8.0-4.el5_5.3.x86_64.rpm

yum erase ImageMagick

yum --nogpgcheck install \
ImageMagick-6.2.8.0-4.el5_5.3.i386.rpm \
ImageMagick-6.2.8.0-4.el5_5.3.x86_64.rpm \
ImageMagick-devel-6.2.8.0-4.el5_5.3.i386.rpm \
ImageMagick-devel-6.2.8.0-4.el5_5.3.x86_64.rpm
[/code]

If those are official CentOS packages they should be signed so "--nogpgcheck" should not be required, nor should it be necessary to download the packages manually. This worked for me:

[code]yum --noplugins --enablerepo C5.7-base downgrade ImageMagick-6.2.8.0-4.el5_5.3 ImageMagick-devel-6.2.8.0-4.el5_5.3[/code]

The "--noplugins" is necessary for me because yum-priorities is installed and priorities are not defined for the repos in /etc/yum.repos.d/CentOS-Vault.repo.

Note also that [b]exclude=ImageMagick*[/b] should be added to the [base] and [updates] repos to avoid the downgraded versions from being overwritten by the later versions on the next "yum update".

of course this just became very difficult to do because CentOS 5.7 just disappeared from all public mirrors overnight

That's why my procedure above uses the CentOS-Vault repo.
