Rebase problems in Ruby

Rebase problems in Ruby

[Chloe]

I'm trying to run 'rails console' in an app with many, many gems (not a test 
app) and it is giving me these errors. I've already tried to run 'rebaseall' 
with ash and I also ran 'rubyrebase' using a script I found on this list 
archive. Neither helped. I've tried several times. 'cygcheck -c' says 
everything's OK. These are the errors I'm getting:

So where are these gems coming from and how many are there?  Too
many/ones from unknown places are going to be either missed
by 'rubyrebase' or be impossible to fit in memory without
collision with other installed DLLs.  See this thread for more
discussion of this:

The next release of 'rebase' will include the perlrebase/rubyrebase
functionality, so this should be fixed then.  In the meantime, you can
install ruby-rails and its dependencies from Ports, in which case you
should rebase once more and NOT use rubyrebase.

If any existing process has the file open, you would see this.
There might be other causes as well.

While rebase problems can indeed be a bit of a pain, some
patience and persistence should lead to a solution ...

FYI, I saw these lines in the output. I don't know if they are relevant. 
Notice pixman was rebased, and notice it said ruby.exe was not rebaseable.

$ rebaseall -v > rebase.lst
/usr/lib/perl5/5.14/i686-cygwin-threads-64int/CORE/cygperl5_14_2.dll: 
skipped be
cause nonexistent.
$ grep pixman rebase.lst
/usr/bin/cygpixman-1-0.dll: new base = 68d60000, new size = 90000
$ rubyrebase > rubyrebase.lst
/usr/bin/find: `/usr/lib/ruby/site_ruby/1.9.1/i386-cygwin': No such file 
or directory
/usr/bin/find: `/usr/lib/ruby/vendor_ruby/1.9.1/i386-cygwin': No such 
file or directory
/usr/bin/ruby.exe: skipped because not rebaseable


Unfortunately I must forgo Cygwin for native Windows executables.

If they are "standard" fpr you, Cygwin may not know about them. You have to
manually supply a list of shared libs and applications your project depends
upon to rebase them on the same ground with the rest of Cygwin.

They come from 'bundle install' and 'gem install'. The standard Ruby 
places. There are about 100 in my Gemfile. The same project works on 
WinXP, but not Win8. I don't see how it can't fit in memory. My WinXP 
has 1GB and my Win8 has 8GB. I've run rebaseall and rubyrebase several 
times, and re-installed ImageMagick and libpixman_1.0 several times.

I just can't get past this problem. Does this mean I have to give up on 
Cygwin?
