Hi,

I contacted VisIt's upstream (via visit-users list) and found the same thing; they are
correcting the build notes that claim Silo is needed.

I hadn't tested it without Silo. I'm trying to build it now, but Visit 1.12.0 needs VTK 5.0.0c : I tested against vtk 5.2 which is in Debian, and they're incompatible; LLNL ship a VTK 5.0.0.c (with changes) tarball to build VisIt with; it doesn't build on Debian, so back to working on the necessary fixes for visit 1.12.0 with Debian's VTK.

(Some of these may be in the repo for visit ; they are currently working on visit 2.0
upstream, but I'm not sure it would be ready for Squeeze).

I need to resign up to ITP visit.

Regards
Alastair

This seems to be very awkward: a Free Software application (VisIt)

AFAIK, this is a show-stopper for packaging VisIT. We could write to
LLNL and see if they
are willing to relinquish this,

I think this should definitely be done.

I got in touch with Silo's upstream.
They quickly replied in an encouraging manner.
First thing they told me is that Silo is no longer a mandatory
dependency for VisIt: they say it's been an *optional* dependency for
quite some time.

Alastair, did you try building VisIt without enabling the Silo plugin?

I think VisIt could be packaged for Debian (main) with the Silo plugin
disabled, while we wait for upstream to re-license Silo in a DFSG-free
manner...
Does it sound feasible?


but since I started this ITP, Paraview has been packaged for
Debian, and it does my visualisation needs, so I am no longer
packaging visit.

Sorry about this,

Alastair, does the above pieces of news change anything with respect to
your willingness to package VisIt?


Please let me know: thanks in advance.
