Delphi 2009 can't find record that is declared in a package

Question

In Delphi 2009 there is a package, that was installed properly, and works.

However when a code compiles it throws an error

error E2003: E2003 Undeclared identifier: 'TSomething'

Why and how to fix it? (include the .dcu? the .pas?)

The project is build without "build with runtime packages" option.

Answer 1

You probably have forgotten to include the unit that contains the definition of TSomething. Being in a package doesn't mean you don't have to use the units explicitly.

Another possibility is that TSomething is defined in the implementation part of a unit in which case it can't be accessed from outside the unit.
