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?
Thanks and regards,
Mario

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.

Thanks Dan and Ayla for your prompt response! When do you plan to
release
2.1.5?
As for the 3rd party libs, unfortunately, Fedora has a strict policy
of not bundled and not static libs:
https://fedoraproject.org/wiki/Packaging:No_Bundled_Libraries
https://fedoraproject.org/wiki/Packaging:Guidelines#Packaging_Static_Libr...
The only exceptions granted are usually for libraries that are heavily
modified. Does any of the 3rd party libs in "external" meet this?
Including seg3d in a distribution like Fedora it is usually a positive
force: it means a large user base, continuous feedback, builds ready
available for x86, arm and ppc archs, access to last releases of all
libs, prompt bug reports and many submitted patches. It also relieves
you part of the burden to assist users with bugs: package maintainers
will usually catch them up early and report to you, sometimes along
with a proposed fix. Thus you can concentrate more on working on your
software instead of all the maintenance tasks.
You can think about it as an investment :).
However, it needs a bit of involvement by your side because I cannot
maintain a complete fork of seg3d.
In the end I don't think the process is so complicated: we just need
to ensure we can choose at build time whether to link seg3d with the
included static libs or against system wide ones. I can send a patch
for this, if you are willing to review it. Then, if any
bugs/regression arises, we will work towards a fix.
I do hope that this would be the beginning of a long joint collaboration!
With best regards,
Mario

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.
