Dotted RTL how to use lazarus / 62-General ---------------------------------------------------------------------- my_only_lonely · 2025-06-12 03:50 I have read the doc https://wiki.freepascal.org/FPC_Dotted_RTL, and compiled a new RTL. But how can I use this version of RTL, is there any switch I should add? Lazarus still cannot compile when uses a dotted unit, like System.Generics.Collections, it says it cannot find the unit. ---------------------------------------------------------------------- PascalDragon · 2025-06-13 21:19 You need to make sure that the fpc.cfg of the compiler that Lazarus uses points to the correct RTL (maybe even with a separate ifdef so that you can relatively easily switch between dotted and non-dotted RTL).
