Hi All,
           I have just installed the latest edition of Lazarus and fpc,,but
I am not able to compile any projects as I get these errors :
 
       1. Unit not found interfaces
       2. Cannot compile INTERFACES no source found

In the Environment option > files I have fiven all the paths
 
       LAzarus directory = \..\Lazarus\
       fpc dir           = \urs\..\fpc386
       Source Dir        = \..\Source\lcl (etc etc)

Do I need to edit any config file ? Please let me know as I want to use Lazarus 
as soon as possible

TIA
Jay Dubal
