Release Notes


Release 6.0 of AVS/Express is available for the following platforms:

  • Windows 95/98/NT 4.0/2000/XP
  • Compaq Tru64 UNIX 5.1
  • HP HP-UX 11
  • IBM/AIX 4.3.3
  • Red Hat Linux 6.0
  • Red Hat Linux 7.0
  • SGI IRIX 6.5 (n32 MIPS3)
  • SGI IRIX 6.5 (n64 MIPS4)
  • Solaris 7
  • Solaris 8

For more details, see System Prerequisites.

The Solaris 8 and Red Hat Linux 7.0 support are new for this release. There are now two versions of Express for Linux, and their requirements for additional software are somewhat different. Please read the Linux System Prerequisites carefully.

The documentation search feature requires a Java-enabled web browser. Note that Netscape users should have Netscape version 4.7 or greater to view the AVS/Express documentation. Linux users should note that we have found the Mozilla browser to provide font rendering superior to that of Netscape on Linux.

Development Notes


AVS/Express 6.0 and Toolmaster 7.2

It should be noted that when installing AVS/Express 6.0 and Toolmaster 7.2 on the same PC, there could be conflict with UNIDIR setting. agX reads any UNIDIR value in the registry and, if one is found, ignores the UNIDIR environment variable. Therefore, if UNIDIR is set in the registry, it will always override the parameter being passed by AVS/Express. If you experience runtime errors using agX, make sure that there are no erroneous UNIDIR values set in the registry.

Workaround for COM/ActiveX Control Generation problem

The following represents a work around to prevent AVS/Express-based ATL/COM components from crashing. The problem is that AVS/Express, within the ATL/COM control, is trying to initialize certain components of the AVS/Express UI kit. To prevent AVS/Express from doing this, simply comment out the call to UIinit in xexpress.cxx which would be a part of the control's project files.

An AVS/Express-based COM or ActiveX control should not be using any AVS/Express UI widgets. (The reason for making a control in the first place is so that you can put the AVS/Express visualization into a true PC-based application environment.)

Solaris 8

Warning message when running an imaging application

If you use examples from the Imaging section of the Examples library or other imaging application that uses the IP kit on Solaris 8, expect a warning message about the use of the XIL interface ("WARNING: XIL OBSOLESCENCE"). We are aware that the interface has been declared obsolete.
