I went there and added the directories as follows (on one line):
/home/bosse/Engineering/SSR8GUI/Source/;
/home/bosse/Engineering/SSR8GUI/AgiAdmin/;
/home/bosse/Engineering/SSR8GUI/Common/

Then I did a Quick Compile and got the not found error for the first 
unit mentioned in my test unit:
"Fatal: Can't find unit Class_AXD used by unit SSManager"

Of course I have verified that the Class_AXD.pas file is actually located in

the second of the directories listed above.

Do I have to change the extension of the pas files to pp in order for
Lazarus to find the used units? Maybe pas is not a recognized ext?
