Hello,

As reported in another thread (sorry for the squatting), after an update (lazarus-0.9.30.2-fpc-2.4.4-win64) I now have applications that compile no more: error is C:\lazarus\lcl\interfaces\win32\interfaces.pp(32,3) Fatal: Can't find unit InterfaceBase used by Interfaces.

A fresh new project, with a single button, compiles.

I deleted the project (.lpr & .lpi) in the directory where is one of my faulty applications and Create a freesh new application and save it with the project name of the faulty application in the directory of the faulty application and a new name for the main form unit.

Building the application failed with the above error.

You probably have some old ppu's around.
If this does not happen for a fresh project, try deleting the entier lib folder and all ppu's in the projectfolder for the project that fails.

If that does not help, try compiling with -va and see what goes wrong.

Bart

Have you deleted all .ppu and .o files in the project directory?

Bart a ?crit :

Thanks.

I deleted the directory lib in the source directory and the project compiles.

I work with two computers and synchronize the directories. The other computer is (was) 32 bits and has a lib/i386-win32 directory in addition of the lib/x86_64-win64. The synchronization copies both directories on both computers.

But that was not a problem a couple of monthes ago.
