D4: using *.DCU without source?

I have the following problem:
When I try to use a *.DCU without having the source code, the Delphi 4 compiler gives me the following error message:
"[Fatal error] File not found: 'F:\Delphi\Delphi4\Imports\MyUnit.pas'"

The same project compiles fine in Delphi 3, the path to the *.dcu is in the path for my project

Any ideas?

You can't use D3 DCU's in D4! To use the unit, you need the sourcecode to be able to recompile it in D4. This applies to all versions of Delphi, DCU's are only valid for the version that has compiled them...

Oooops - sorry, I complete forgot that this question had been answered.

I'm not happy about the answer :-(( - but since it's apparently correct, it's an A after all. I shouldn't have assigned 60 points though :-))

Thanks!

btw: Does everybody agree that you cannot use any component without having the source code? What if you want to use your project in the next Delphi version??

When you use 3-part components, ALWAYS be sure to get the sourcecode, otherwise you'll face problems like you do now....
