Laura,
What I discussed with you wasn't totally correct. There is no guarantee that an
application compiled on version 3.* of Digital UNIX will run on the next major
release, eg. 4.0. Version 4.0 uses a new and improved compiler which is better
at catching non-std code that the 3.* compiler would miss This could require
code changes.
Also, the command that c++ uses to link varies depending on the version of the
operating system that is being used. You may need to change your ld command
line when you change versions of DEC C++ or Digital UNIX.
If you app requires x11 dependencies, Version 4.0 now supports R6. This could
cause problems if you rely on R5.
If you'd like, i could send you the release notes for Digital UNIX 4.0.
One more thing, since 4.0 was realsed more than 6 months ago, you will not have
formal support (in the way of bug fixes) for 3.* versions. Digital's policy is
to have the customer upgrade since many problems and bugs are often resolved by
upgrading to the newest release.
If you would like to schedule time in our porting center to try your application
on Digital UNIX 4.0, please call 1-800-332-4786 and choose option 4.
