Hi Guilherme,

Excellent!

This says that a full development environment was not installed on the
workstation.  In particular, the include files and most likely the libraries
needed for X windows development were not installed.  You need to install
the necessary packages (rpms) in order to build McIDAS from source.

No.

The problem was most likely caused by incorrectly running the MAP command
when trying to overlay on top of a satellite image.  Here is one possible
scenario:

- display an image
- draw a map specifying SAT or OLAY as the map type (correct)
- run MAP specifying FILE= or specifying a map type that causes MAP
  to rewrite the navigation associated with the frame 
- try to run MAP again and there does not appear to be any navigation

I would try the exercise again and this time be careful to not run a MAP
command that rewrites the frame navigation.  This is most easily done by
including the PRP=SAT keyword combination on the command line.  Please
review the online or Users Guide pages on the MAP command for more explicit
infomation.

Cheers,

Tom
