[Developers] Beta 2.0

[Bert Bril]

Hi all,


Finally ... finally we made it. The version 2.0 beta is now in the 
download center.


For developers, a main issue is that we adopted gcc/g++ 3.4 . This 
finally gets us in the 'files > 2GB' part of the world. For the rest, 
porting to 3.4 is relatively easy. If you don't have 3.4 yet on your 
system, the following applies:

* On Linux, we recommend compiling gcc from source. If you want to use 
packages be aware that it's not always 100% smooth. At home my Debian 
installation feels pretty sick and I can no longer use the Gnome window 
manager after apt-get gcc-3.4 :-( . Here at the office, we made gcc 3.4 
from source on a SuSE 8.1 machine without any problems.

* On Solaris, there is a gcc-3.4 on sunfreeware.com which works 
out-of-the-box.

* On windows, the latest version of Cygwin is based on gcc-3.4 .

For Mac, we stick to gcc 3.3 because it's part of the OS. IRIX is not in 
the beta, and the release will be 3.2 unless SGI get the 3.4 working on 
IRIX before Christmas.

We also plan to release Linux 64 bit in the real release and possibly 
Solaris 64 bit, too.


The main software changes are the tracking system (which needs a good 
redesign so don't rush making plugins for it) and 2D seismics. In some 
places you now need to be aware whether the data you're handling is 2D 
or 3D. But basically, the SeisTrcReader and SeisRequester know about it 
which means you won't be confroneted with it in most cases.

New concepts include the BinIDValueSet (set of postions with arbitrary 
number of values. Quick searching.), The RCol base class generalising 
(i,j) indexed position objects (like BinID), the new multi-machine job 
engine.


Hope you'll like the new stuff.
