To be on the safe side we should assume a transition is required.

Unfortunately libterralib is not very actively maintained, so I had a
look into this issue as part of team maintenance.

The previous Uploaders are included in the CC for their view on the
license issues that were uncovered in the process.

I started on the package by creating a git repository and importing all
previous releases because the Subversion repository on Alioth is very
outdated:

http://anonscm.debian.org/cgit/pkg-grass/libterralib.git

I've updated the package for the move to Git, and renamed the library
package to include the SOVERSION for which a bug was outstanding
(#701143). This is helpfull to avoid appending v5 to the package name,
this SONAME fix suffices.

While updating the copyright file using copyright-format 1.0, I noticed
some non-free issues that will need repacking of the orig.tar.gz at least:

 * src/DSDK/*

   This code is Copyright (c) 2004 LizardTech, Inc, 1008 Western Avenue,
   Suite 200, Seattle, WA 98104. Unauthorized use or distribution
   prohibited. Access to and use of this code is permitted only under
   license from LizardTech, Inc. Portions of the code are protected by
   US and foreign patents and other filings. All Rights Reserved.

 * src/terralib/drivers/Oracle/*

   The OCI license doesn't allow modification nor distribution, see:

   http://docs.oracle.com/cd/B28359_01/appdev.111/b28395/title.htm

We'll need to resolve these license issues for the GCC 5 related upload
to not be rejected from the NEW queue.

I'm having a hard time figuring out how the orig tarball was created, it
looks like the build/ directory is from the upstream v-4-0-0 SVN tag
because the v-4-3-0 tag only includes the cmake subdirectory. The src/
and examples/ directories seem from different tags too.

The Debian package build uses the build/qt4/ build system, so using only
the current upstream tag is not going to work. A get-orig-source target
to create the tarball would have been nice.

It seems that the SOVERSION in the package name was not the only change
that got lost along the way, the changelog for libterralib (3.3.1-2)
includes:

  * Remove unused and copyright-troublesome Oracle, DSDK , MySQL,
    PostgreSQL sources.

It looks like everything under src/ except src/terralib/ can be dropped
from the upstream tarball which would get rid of the non-free DSDK, but
the problematic drivers under src/terralib/drivers/ need to removed too.
The build system will need to be patched for that some more.

@Alastair, as the most active uploader of libterralib and its reverse
dependencies, how do you want to deal with these license issues and the
GCC 5 transition?

Kind Regards,

Bas
