Solution: compile everything with -Ur (= "create release units"; the compiler will never try to recompile such units afterwards, except if the interface section of a unit that it uses has been changed and this other unit has been recompiled).

Hello, thanks very much, Jonas and Mattias! I think your tips will help me a lot. I will go back to Macintosh development in about a month. If you don't hear from me, I'm fine!

Before trying again I wanted to make sure I had the best version of FPC available. I had problems with units not being found although they were on the search path allright.

In that case, the compiler will ignore the precompiled unit and try to recompile it. If it then doesn't find the sources, you'll get an error about the unit not being found. Another common reason: You added too many search paths. Lazarus compiles each package separately. Each run needs distinct search paths. Otherwise you create duplicate ppu files. Also installing packages into Lazarus caused all kinds of unit conflicts (Recompiling XYZ.pas because the checksum changed although it didn't). These things won't change if you update FPC. If anything, you'll probably get more such problems because mixing units compiled by different compiler versions can also cause such issues.
