Hi, everyone.
I`m getting the error "Can't find unit InterfaceBase used by Interfaces" when I try to compile a simple project with Lazarus 0.9.26 under Windows XP Home on an eeepc 901, 1024 of RAM.

I just installed by the exe-file downloaded from sourceforge, and tried to compile, by pressing the green "play" button.

Some more details:
Lazarus Directory: C:\InstLazarus\
Compiler path: c:\InstLazarus\fpc\2.2.2\bin\i386-win32\fpc.exe FPC Source Directory: c:\InstLazarus\fpc\2.2.2\source\ Make Path: C:\InstLazarus\fpc\2.2.2\bin\i386-win32\make.exe

Section Paths in Compiler Options is all blank.
Only LCL Widget Type (various) is assigned to "default (win32/win64)"

Thanks for the help.

Anyone has any ideas about this one? I think it should just work.

Which project are you compiling? If it's a new project you need to save it before running.

Test with a simple project.

What is your architecture? Maybe you are running a computer with 64-bits, and you installed the 32-bits Lazarus, but the compiler tryes to build for 64-bits .... a wild guess, but could be it =)

Thanks, Felipe.
I'm trying to compile a simple test project, with only a button with showmessage('hello world') in it. I tried to save it first, in order to test like you told me, but the error is the same.

The architecture is 32-bits. I installed the same downloaded file at another computer, under Windows Vista. It works normal.

I just copied the install directory from a machine to another, as a last chance, but it didn't work.

I don't know what to do now. Maybe it's something with XP Home...
