Trying to update gd

Hi All,

I found that gd was at version 2.0.33 from 2006 and there have been 
several updates all the way up to May this year, some of them to fix 
bugs or security concerns.


So I did a build for version 2.3.1 also taking the opportunity to 
disable-static  libraries.

This built successfully and I also ran the find-dependencies as the 
libraries changed from libgd.so.2.0.0 to libgd.3.0.9  There were no 
dependencies on libgd.so.2 or libgd.2.0.0

As gd is used for the charts I installed the generated iso into a vm on 
my testbed system to confirm they worked.

None of the charts showed any data. Also the log pie charts did not 
work. The error message from httpd/error_log was:-


Can't load 
'/usr/lib/perl5/site_perl/5.32.1/x86_64-linux-thread-multi/auto/GD/GD.so'

This seems to be saying it can't find libtiff.so.5

Looking through the source tarballs over time I found that version 2.1.0 
was where it started to look for libtiff.

I then installed the libtiff addon in my vm and the charts were all 
working. So the new gd requires the libtiff shared object libraries.

The addon installs a lot more than just the libtiff so libs so it does 
not seem right to build that structurally into the firewall.


The only option I have come up with is to copy the libtiff so's into 
/usr/lib/ after the install stage of gd.

libtiff is built before gd so the files are available in the build. This 
would seem to then provide the required libs without the rest of the 
libtiff files.

Is this a reasonable approach to use or is there a different method I 
should be using.


Regards,

Adolf.
