[Lazarus] Strange linker messages "undefined reference" when building on RPi4 - CompileLog_2022-04-15.log (0/1)

[Jean SUZINEAU]

Unfortunately my lazarus is installed in French , I don't have the exact 
label of the menu item in English,

But usually for this kind of problem I use "Nettoyer et construire" in 
"Exécuter" menu.

I imagine that in English it's something like "Clean and build" in "Run" 
menu.

In this dialog you can tune what compiled files you want to delete in 
the various dependencies.
