@subsection Can I use setup to install snapshots?
Yes. If experimenting with developer snapshots from
No. It used to be possible, but not any more.
If experimenting with developer snapshots from
@file{http://cygwin.com/snapshots/}, you should generally install the
full @code{cygwin-inst-YYYYMMDD.tar.bz2} update, rather than just the
DLL, otherwise some components may be out of sync. However, Cygwin tar
won't work because it will load the DLL that you're trying to update,
and a non-Cygwin program like WinZip will put everything in the wrong
place. The solution is to use @code{setup.exe}.
DLL, otherwise some components may be out of sync. Cygwin tar won't be
able to update @code{/usr/bin/cygwin1.dll}, but it should succeed with
everything else. The following steps should work:
Just bunzip2 the cygwin-inst tarball, rename it to cygwin-YYYYMMDD.tar,
gzip it, put it in an empty directory, and run @code{setup.exe} there.
You should be given the option to install it.
@enumerate
@item Download the snapshot, and run:
@example
cd /
tar jxvf /posix/path/to/cygwin-inst-YYYYMMDD.tar.bz2
cd /tmp
tar jxvf /posix/path/to/cygwin-inst-YYYYMMDD.tar.bz2 usr/bin/cygwin1.dll
@end example
@item After closing all Cygwin apps (see below), use Explorer or the
Windows command shell to move @code{C:\cygwin\tmp\usr\bin\cygwin1.dll}
to @code{C:\cygwin\bin\cygwin1.dll}.
@end enumerate
The obvious warnings about updating the cygwin package and using developer
snapshots apply:
@enumerate
@item Always download the latest version of setup from
@file{http://cygwin.com/setup.exe}.
@item Close all Cygwin apps, including shells and services
(e.g. inetd), before running setup. You may have to restart Windows to
clear the DLL from memory.

@item Snapshots are risky. They have not been tested. Use them @strong{only} if
there is a feature or bugfix that you need to try.

to deal with any problems.

site, use a mirror, and look in the @samp{snapshots} directory. You may
