Subject: Creating "windows binaries" on Linux

There was some discussion about packing Windows executable with 
tar2rubyscript and rubyscript2exe from a Linux box. Wine was proposed 
but I publicly dismissed with the claimed that it didn't support WinXP 
calls (and thus not win32-utils). ruby-talk:172349

But I was wrong. wine DOES support WinXP calls, ruby and win32-utils. I 
am right now building a cross-platform application with wine 0.9.5, ruby 
1.8.2 (one click installer) and wxruby, all from my Linux machine. 
tar2rubyscript and rubyscript2exe were installed from gems. Here is what 
my rakefile looks like:

------------
DIST = "deviceproxy2"

task :default => [:run_windows]

task :run_linux do
   ruby "init.rb"
end

task :run_windows do
   sh 'wine ruby init.rb'
end

task :pre_build do
   sh "rm -f #{DIST}.tar #{DIST}.tar.gz"
   sh "darcs dist -d '#{DIST}'"
   sh "gunzip #{DIST}.tar.gz"
end

task :build_linux => [:pre_build] do
   sh "tar2rubyscript #{DIST}.tar"
   sh "rubyscript2exe #{DIST}.rb"
end

task :build_windows => [:pre_build] do
   sh <<EOF
unset TMPDIR
wine ruby 'C:\\ruby\\bin\\tar2rubyscript' --tar2rubyscript-preserve 
#{DIST}.tar
wine ruby 'C:\\ruby\\bin\\rubyscript2exe' #{DIST}.rb
EOF
end
---------------

The only gotcha is --tar2rubyscript-preserve. For some reason, when 
running tar2rubyscript with wine, it fails with an error:

--------------
c:\windows\temp\tar2rubyscript.d.66.1\tar2rubyscript\tar.exe: Cannot add 
file *.*: No such file or directory
--------------

Using a tar ball and --tar2rubyscript-preserve skips this step and 
everything is cool.

Maybe someone will find this information useful,
Guillaume.
