Right click the error message in Lazarus, then click "Help". For me a
dialog with the following text appeared:

"A generic declared in the interface section of a unit must not reference
symbols that belong solely to the implementation section of that unit."

The *why* is not important for users. Those that are interested can ask,
just like you did.
