You are urged not to +choose something like 'C:\' (the root directory on the system drive) for +your Cygwin root. If you do, then critical Cygwin system directories +like 'etc', 'lib' and 'bin' could easily be corrupted by other (non-Cygwin) +applications or packages that use \etc, \lib or \bin. Perhaps there is +no conflict now, but who knows what you might install in the future? +It's also just good common sense to segregate your Cygwin "filesystems" +from the rest of your Windows system disk. (In the past, there had been +genuine bugs that would cause problems for people who installed in C:\, +but we believe those are gone now.) + +@subsection Can I use the new setup to update a B18, B19, B20, B20.1 or CD-ROM (1.0) installation of Cygwin? + +No, you must start from scratch with the new setup. The overall +structure has changed so much that it would be silly to try to +accomodate old installations of Cygwin. You'll probably be much better +off with a whole new installation anyway. You may backup or rename your +old installation first, or just install the new one somewhere else. Be +sure to make note of your current mount table, because this will be +overwritten during the new setup. + +Once you've installed the latest net release, the new setup will update +just the individual packages that need it. + +@subsection The README says I should turn off anti-virus software. Isn't that dangerous? + +Only Network Associates (formerly McAfee) products have been reported to +"hang" when extracting Cygwin tar archives. Other products should not +cause problems, if you prefer to keep them running. + +Otherwise, you can download @code{setup.exe} and scan it. Then turn off +the anti-virus software, then run setup to download and extract all the +tar files. Then re-activate your anti-virus software and scan +everything in C:\cygwin (or wherever you chose to install). This should +be safe. (As long as nobody substitutes a malicious setup.exe ...) + +@subsection What packages should I download? + +Just get everything, if you have room for it. But if you must be +selective: + +@table @samp + +@item cygwin +This is the minimum core, consisting of the cygwin1.dll and a few +commands (like @code{mount}). Not much else, and no shell! + +@item bash +This is the default interactive command shell for cygwin. If you don't +install @samp{bash}, then the "Cygwin Bash Shell" shortcut that setup +creates for you won't actually do anything. + +@item ash +This is often forgotten because it's not obvious that @samp{ash} +contains @code{/bin/sh}, which is essential for running scripts, (and +@code{make} and ...). + +@end table + +If you want to build programs, of course you'll need @samp{gcc}, but +you'll also need @samp{binutils}, probably @samp{make} and +@samp{fileutils}, and possibly lots more. (Again, consider just getting +everything!) + +@subsection What if setup fails? + +If you are downloading from the internet, setup will fail if it cannot +download the list of mirrors at +@file{http://sources.redhat.com/cygwin/mirrors.html}. It could be that +the network is too busy. Similarly for an ftp download site that isn't +working. Try another mirror, or try again later. + +If setup refuses to download a package that you know needs to be +upgraded, try deleting that package's entry from /etc/setup. If you are +reacting quickly to an announcement on the mailing list, it could be +that the mirror you are using doesn't have the latest copy yet. Try +another mirror, or try again tomorrow. + +@subsection What's the difference between packages in @samp{latest} and @samp{contrib}? + +Good question! That very issue is sometimes debated on the +@samp{cygwin-apps} mailing list. Check the list archives if you want to +know more. |
