acolite throws an error when it's directory is not writable #473

Closed naterubin closed 6 years ago

naterubin commented 6 years ago

When the ACOLITE_DIR (in this case /opt/acolite_linux) is not writable by a user, the process reports this cryptic error message and exits:

'IDL Version 8.4 (linux x86_64 m64). (c) 2014, Exelis Visual Information Solutions, Inc.\n\n% ACOLITE: Running ACOLITE for 1 image.\nError -254:  Error opening file. Unit'

The solution, naturally, is to make sure that ACOLITE_DIR is writable. Although this issue is solved, it is worth recording the fix as it is hard to determine what is going on solely from the error message.

It also explains why I didn't see the error: I believe my ACOLITE_DIR was in my homedir during my testing, and therefore owned by me.
