Answer 1

Delphi XE2 does not ship with a unit named Vcl.Imaging.jpeg.pas . It ships with a pre-compiled DCU file named Vcl.Imaging.jpeg.dcu . You need to link against the pre-compiled DCU and not attempt to compile a VCL unit. The error message you are getting can only occur when you attempt to compile a unit from source. You cannot get this message if you pass a pre-compiled DCU to the linker.

I suspect that your .dpr file contains references to a file named Vcl.Imaging.jpeg.pas . Solve the problem by removing the references to Vcl.Imaging.jpeg.pas from your .dpr file. Another explanation is that you have a source file named Vcl.Imaging.jpeg.pas in your search path.

Answer 2

The best solution from DevExpress Forum:

To solve this issue, add the Vcl.Imaging name space to your application by using the Project->Options->Delphi compiler->Unit scope names menu option.

Answer 3

Find the directory where those obj files live. Make sure that directory appears on your project's search path . (They are not files you're meant to compile for yourself.)

If you don't have those obj files in your Delphi installation, then check the installation DVD.
