Some members of the Free Pascal team also maintain installable snapshots. These are installers, made with the sources of that day. Since the sources are not guaranteed to work, a snapshot of a certain day may not be available, or the person responsible for it didn’t have the opportunity to make one: these snapshots may or may not be available. They can be downloaded from the same page as the daily source zip:
http://ftp.freepascal.org/develop.var
The snapshots are made for the development branch as well as for the fixes branch. They are available from
ftp://ftp.freepascal.org/pub/fpc/snapshot/trunk/
and
ftp://ftp.freepascal.org/pub/fpc/snapshot/fixes/
respectively.
The FTP site is mirrored, it may be faster to use a mirror.
