Hi Mario,
(I guess I should have read this before I have written my previous
answer.) As a general answer there exists a so called Upstream Guide
in the Wiki
http://wiki.debian.org/UpstreamGuide
IMHO everything written there should also apply for Fedora. I'm
personally astonished that the topic of bundled libraries is not (yet)
mentioned there. I'll suggest the authors of this guide to include this
topic.

Dear all,
I had an interesting talk with Seg3D mantainers on the possibility to
accept patches to build against system version of the many bundled libs.
However, as you can see from the forwarded mails, they seem not willing to
help with that nor to accept any related patches. I'm not sure what to do
here: shall I package it regardless? I fear I'll end up mantaining a fork
of the program...
What would you suggest here?
I admit that's a pretty bad situation. We just have some packages where
upstream includes third party software and we were not lucky enough to
convince them about droping it (even if constantly talking to them for
every new version). However, I do not remember any case where really
widely used, large projects like boost or itk are affected by this
problem. That's really bad and I admit I do not have a reasonable
answer to this. For the moment I would regard this as a show stopper
and move to another package on your list.
I personally would not consider to maintain a clean fork if this is more
than say up to ten easily maintainable / automatically generatable
patches. Finally your version will be way less tested and once users
might learn that "the Fedora packages of medical imaging are broken"
(yes, they might do this generalisation even if this is not true) this
might affect your whole project.
We might like to do another try from Debian Med side. Perhaps upstream
might start thinking about it if two major distributions will not
consider something that would be in their interest ...
Kind regards
Andreas.

Hi Mario,
Many of the libraries we include with Seg3D have been modified, even if the
modifications are as basic as replacing their default builds with CMake and
doing some symbol mangling to make libraries play well with ITK. Our Boost
distribution includes a project from the Boost sandbox that will not be
available in a generic distribution. ITK has been customized as well.
Including specific versions of third-party libraries allows us to maintain
stable Seg3D builds across multiple platforms (Windows, Mac OSX and
different Linux distributions) with the least amount of effort for SCI
developers. We are also tightly coupled to Boost, ITK and Teem, so it is
preferable from our point of view to build against versions that we control.
Having a binary distribution for Fedora would be helpful - it's certainly
been a good thing for our Windows and OS X users, however keeping our
dependencies uniform across supported platforms has eliminated many of the
deployment headaches we used to have in the past.

the updates from the 2.1.5 release candidate back to the trunk once the
release is done. We're currently targeting a modified Boost 1.53.0 library
(see the Modifications.txt file in the src/Externals/boost directory). Keep
in mind that Seg3D is designed to work with statically linked libraries
built from the third-party dependencies that we include with it's sources
and does not support the use of other versions. I would strongly recommend
using our libraries and then attempting to work with Fedora's Qt system
libraries.
