oops!

def myduck(x)
puts x + 4
end

sorry that was a bad example! Who’s POLS are we running with here anyway! :stuck_out_tongue:

try this instead:

def myduck(x)
puts x.size
end

sorry, should have tested it first.

Ok,

I’ve got it compiling now and here is my next obstacle.

I tried:

···

I:\source\languages\ruby\source\ruby-1.8.1\ext\tcltklib>nmake
DESTDIR=I:\ruby install

Microsoft (R) Program Maintenance Utility Version 6.00.8168.0
Copyright (C) Microsoft Corp 1988-1998. All rights reserved.

NMAKE : fatal error U1073: don’t know how to make
‘I:/ruby/ruby/lib/ruby/1.8/i386-mswin32/ruby.h’
Stop.

You can see my issue. However I thought I would do things the ‘manual’. so I
then did:

I:\source\languages\ruby\source\ruby-1.8.1\ext\tcltklib>nmake

and it worked. I got my tcltk.lib and tcltk.so file. I put them in:
I:\ruby\lib
I put the tcltk.rb file in: I:\ruby\lib\ruby\1.8

I cannot say: require ‘tk’

it outputs:

i:/ruby/lib/ruby/1.8/tk.rb:7:in require': No such file to load -- tcltklib (LoadError) from i:/ruby/lib/ruby/1.8/tk.rb:7 from deleteMe.rb:1:in require’
from deleteMe.rb:1

Exit code: 1

Does anyone know of any other files i need in order to get tk to work.
Everything is compiled from
scratch so I am starting from the ground up.

My Development Stats:
-Windows 2000
-Ruby 1.8.1preview2
-Tcl/Tk 8.4.4
-Microsoft Visual Studio 6(i couldn’t get borland to find the tcl84.lib and
tk84.lib files)

Thanks,

Zach
