There are a few important changes to the IDL infrastructure that I have not already discussed in the IDL 8.0 related posts so far. I’ll have one final wrap-up post after this one.

First, the location of the default IDL installation has changed—there is another level added to the hierarchy. For example, by default on a UNIX system, IDL 7.1 was installed in:

/usr/local/itt/idl71


Now, IDL 8.0 is installed in:

/usr/local/itt/idl/idl80


Be careful, this installation location will destroy the link that most of us had at /usr/local/itt/idl to the current IDL version.

Also, system administrators take note: using a network license with IDL 8.0 requires the download and installation of the IDL 8.0 FlexLM License Server. So admins familiar with updating previous IDL installations will have to do something a bit different this time.
