	SCons is indeed not clean after -c. There are the .sconf_temp directory, config.log, .sconsign_dblite, and various .sconsign files in subdirectories. All of these need to be deleted to get a really clean build. There is a cleanup shell script in the csound root directory that attempts to do this. The script doesn't work for me on Windows, but it probably can be modified for you if it does not work on your system. Hope this helps, Mike -----Original Message----- >From: Hector Centeno >Sent: Feb 25, 2008 5:35 PM >To: csound@lists.bath.ac.uk >Subject: [Csnd] Re: Re: [SOLVED]: please help with csound and python > >Cesare, > >I've got that kind of error when rebuilding after doing a scons -c in >a already built source direcotry.
