A few notes taken while trying to get Rails working on Cygwin:

  • Stock Ruby works perfectly (so far)
  • Getting gem to work is also standard fare (get tar file, unpack, ruby setup.rb)
  • Installing Rails using gem works first time, but is slow (generating documentation takes a long time)
  • Tests work, but there's no decent database support.
  • The sqlite-ruby gem does not like SQLite3 (which, incidentally, installs and works fine in Cygwin, provided you run configure --disable-tcl and use a separate build directory). I have, in fact, tried gem install sqlite3, but the results were less than optimal. Maybe next time.

The right incantation for building the gem seems to be:

gem install sqlite-ruby -- --with-sqlite-lib=/usr/local/lib \

...but it does not like the new "3" suffix on headers and libs.

  • Unpacking sqlite-2.8.16 and installing it (also without Tcl support) worked:
$ gem install sqlite-ruby -- --with-sqlite-lib=/usr/local/lib \
> --with-sqlite-include=/usr/local/include

Building native extensions.  This could take a while...
Successfully installed sqlite-ruby-2.2.3
Installing RDoc documentation for sqlite-ruby-2.2.3...

If you have problems building the native extensions, try doing a rebaseall on a standard Cygwin prompt without any Cygwin-based daemons running.
