              VLT COMMON SOFTWARE "APR2004" - OVERVIEW
              ========================================

The APR2004 release is an external release and it will be distributed
to consortia (CDs with OS, VLTSW sources and manuals).

The release notes for APR2004 reflect only the move from APR2003 to 
APR2004.
To have a complete picture of the changes from previous releases, have a 
look at the page: 
    http://www.eso.org/projects/vlt/sw-dev/vltsw/index.html


The HP-UX 11.00 requires the installation of new patches, which are 
provided on 1 cd. They are the official annual HP patches "Support Plus". 
The Solaris SunOS 5.8 does not require any patch or change. 
Please follow instructions in the 
"VLT Common Software - Combined OS Installation Manual"
(VLT-MAN-ESO-17200-2238 issue 3)
For Linux, a DVD will be provided. The Linux installation manual is 
available at the page: 
http://www.eso.org/projects/vlt/sw-dev/wwwdoc/add_doc.html

*  REMARK:
  Up to now the only hardware platform accepted by Paranal as target 
  workstation is HP (currently with HP-UX 11.00 and CCS-lite) and 
  consequently this is the standard platform to be used for development
  as well. 
  A Linux DVD containing Linux RH9 OS and VLTSW has been prepared 
  and will be distributed as well, together with the HP cds. 

Important remark on Linux: 
After the tools and the VLTSW installation, new shared libraries get 
installed in the GNU-, TCLTK-, VLTROOT. 
On Linux, the run-time linker needs to know about those shared libs. 
For this it is necessary to perform the following two steps as root:
1) add the lines
/diska/vlt/APR2004/gnu/lib
/diska/vlt/APR2004/tcltk/lib
/diska/vlt/APR2004/CCSLite/lib
(change accordingly to your installation the paths to the "lib" 
directories)
to the file /etc/ld.so.conf
2) run as root the command:
# ldconfig

Note that if you have a previous installation you should remove the 
entries for the previous release.
