(cross-posted on otb-developers and otb-users)

Hello all,

OTB does not have any packages officially supported by any linux distro.
This old story roots back to days where there are lot of embedded sources
inside otb for every dependency it uses. Now they are cleaned up with an
expcetion for 6S and SIftFast.

what should we do about packaging task in OTB ?

Our current strategy is to get the packages ready after release. That is
the time revisit the packaging task. To get it ready too fast by we push
packages into ubunutgis. The thing is it is easy to push into ubuntugis ppa
rather than going for a review.

On the plus side, OTB has packages soon after release and our users are
happy.  We don't stop just with OTB. We do ossim, itk and if possible we
try to add some libsvm, muparserx.

IMHO, This is the wrong way. we must stop this and look at the big picture.
Get the packaging work into DebianGIS. To have it in official it is more
difficult and takes time. But remember you don't have to go through this
with each and every release.

Packaging are updated when Debian/Ubuntu or Fedora has a new release. This
is the way other things work. but OTB updates its packages for every
release. Shouldn't it be the other way round.

Why should we do a package with every release ? Why is it necessary?. If
there is an official packages in debian and then in ubuntu, then we don't
need to do this. right?

ITK does not do this. But in Fedora 23, I have ITK 4.8.2 ? We should try
adopt this.

For users, if they want OTB the next day of release they could build OTB on
their own.  Before saying anything.. building is not that hard since 5.0.
We can all agree on that.

A minimal build needs less than 10 mins. Is that too much for any user
wiating to get the newly added features and performance improvements ?

This can be time I need to install libotb-dev on a fresh ubuntu or debian ?

Also there is a nightly packages for Linux, Windows and OSX. Even so we
feel important to make deb, rpm and maybe something else (I don't know all
distribution) for every OTB.

One more point I would like to add to this long mail is going the wrong way
for packaging always gives users a bad impression. And that feedback may
not even reach our mailinglist before they give up on OTB. Because we have
packaging for "N" distribtions and their "M" versions something will be
surely broken somewhere. And history suggests that it is true.

Thanks all for your patience to read till end of this mail.  I appreciate
your feedback/comments/suggestions.
