Forum: wxRuby how to reduce size of .exe file got from ocra

Hi,

I just create a simple WxRuby app and then try to turn it into .exe file
using Ocra. The code is something like...

require 'wx'

class SimpleApp < Wx:App
   def on_init
       Wx::Frame.new(nil, -1, "Simple App").show()
   end
end

SimpleApp.new.main_loop

However, the exe file from Ocra is quite big, about 5.45 Mb. I think it
is because Wx requires many dependencies so that make this result.
BTW, Is there any way to reduce file size of this exe ?

There should be some freeware out there
to reduce exe file size,
I found two long time ago, but forgot their name

Wut 'sup?

I don't think so, since the 'require 'wx'' line loads all of WxRuby. I
think you'll find that if you write a very elaborate ruby code, along
the lines of 300KB in size, the .exe will not change much.

But if I'm proved otherwise, by all means ignore me.

I believe the exe will be much more than 300 KB in size,
since exe files include all library
it need, and Wx is not a very small one.
about 5 mb is normal

I have used  ruby script2exe before and the result is way bigger than 5 
mb
so yours is fine, really

when I do >ocra very_simple_app.rb, then ocra compile and the trace
looks something like..

I think I don't need to load such dependencies like /samples, etc...
I look into ocra document again and found that ocra will load all
dependencies describe in manifest file of the required gem(or source
file). So that I should be able to reduce size by modify the manifest of
my wxruby.

But the problem is, I cannot find the manifest file in the
/lib/ruby/gem/1.8/gems/wxruby-2.0.1-x86-mswin32-60/, cann't find it from
the root of ruby path as well :P

How can I address ?
Any suggestion, pls?

what about move your samples directory somewhere and try again?
perhaps that would do the trick?
