[SOLVED] Curios error "unit not found: Classes" when renaming a button

[Joe]

I'd just installed Lazarus 1.6 with Fpc 3.0.0 (including source) to my 32 bit kubuntu 14.04 from the provided debian packets:

• lazarus_1.6-0_i386.deb
• fpc-src_3.0.0-151205_i386.deb
• fpc_3.0.0-151205_i386.deb

Creating a new application project with an empty form, build & start works.
Now I'd added a button to my form, which will be named to "Button1" by default. Navigating to the Objectinspector and changing the button's name to e.g. "Hello" will result in an error message:

    Die Variable im Quelltext kann nicht umbenannt werden.
    Fehler: Unit nicht gefunden: Classes
    Siehe Meldungen

What could be the reason for this misbehaviour?

I'd took a look into LCLClasses.pp were I find:

Code: Pascal  [Select][+][-]

1. uses Classes, WSLCLClasses, WSReferences, LCLType, LCLProc;

But in my file system, the `classes.ppu` is written completely lower case.
A dumb tryout by creating a symlink for a `Classes.ppu` won't help.

Any suggestions?

If not mistaken then that means lazarus is unable to locate your fpc sources directory.

There is a menu option, under tools named "rescan fpc source directory" that allows you to rescan for fpc directory. Please give that a try.

edit: inserted correct menu-item location.

Thanks GetMem.

I forgot i can look it up in online wiki as well (on location, so no access to lazarus).

Great, this helped!
