File not found: SDL_xxxxx.dcu

Problem I have installed the entire SDL Suite (for Delphi 6). If I try to compile the example application "poldiag" the compiler/linker issues the error message: File not found: SDL_numio.dcu. This file does not exist on my computer.
Solution The unit names of the SDL Component Suite have been changed from release 8.5 upwards by inserting the prefix "SDL_" in order to avoid name conflicts with units from other third-party developers. Thus you most probably tried to compile a sample application written for release 8.5 or higher with a SDL Suite older than release 8.5.

Solution: Either install the latest version of the SDL Suite, or remove all "SDL_" prefixes in the uses declaration of the sample application.
