[Linker Fatal Error] Unable to open file 'CLASSES.OBJ'

 

 

 

 

 

Cause

 

This happens when you add CBuilder6\Lib\Debug\Vcl.LIB to your project. I did so, because I wanted to have an unresolved external error solved caused be a TImage.

 

 

 

 

 

Solution

 

I think I shouldn't add \CBuilder6\Lib\Debug\Vcl.LIB to your project.
