I checked out the sources using cvs and cant find any configure script. What can I do?
The cvs versions are meant to be used by developers rather than normal users, so the source (or binary) distributions are easier to use. – Yeah, but the latest features from cvs really look sexy… You need to generate the configure script by running ./autogen.sh. Building from CVS requires a lot of extra dependencies that the release tarballs don’t have, as an easier alternative, consider using the daily CVS snapshot instead, available from http://www.claws-mail.org/cvs.php.
