ext/tk/extconf.rb creates Makefile for tcltklilb.so (core library of
Ruby/Tk), when it finds Tcl/Tk libraries (see ext/tk/README.tcltklib).
If it fails to find proper Tcl/Tk libraries, it creates a dummy
Makefile (it can make nothing). So, before retrying to configure
(run ext/tk/extconf.rb), please remove such dummy Makefile.

If ext/tk/extconf.rb cannot create an available Makefile although you
give the paths of Tcl/Tk libraries, please check consistency of
architecture between Ruby and Tcl/Tk.
When 32bit <=> 64bit or 64bit <=> 32bit, probably ext/tk/extconf.rb
doesn't select the Tcl/Tk libraries to make tcltklib.so.

If you're interested in a 1.8.x that works with tk, see
http://rubyinstaller.org/downloads/
"Ruby 1.8.6-p27 (RC2)"

Install that, and activeState 8.5 in your path and it should "just work"

Reproduce ruby not "finding" Tk to compile it in.

I think so.

I'm not sure I've never built it using mswin.

If you want to build it with mingw checkout the tcl branch of
rubyinstaller:
http://github.com/oneclick/rubyinstaller/tree/tcl


if you run a rake from there
(rake ruby1
it should build ruby with the tk extension built.

>> Do you have any response to this (it's a gem)?

Typically when you're just starting ruby on windows, it's recommended to
use a pre-built package instead of building it yourself.

gem is ruby's way of distributing libraries easily. google for rubygems.

If you unpack that zip file (download 7 zip to be able to extract it),
you'll get a full fledged ruby 1.9.1 with the Tk extension already
built.

By dummy Makefile do you mean an empty one? There is a Makefile but
there is stuff in it. I deleted it and tried to recompile but now having
problems with the Microsoft tools this tutorial wants me to use.

This is getting more and more confusing. How do I check check
consistency of architecture between Ruby and Tcl/Tk if it's 32 bit or
64? I thought 32 bit apps can run on a 64 bit machine. This tutorial is
really awful. It gives me nothing but problems every step of the way. Is
there some better way to learn Ruby/tk? And why does he want me to use
1.8.x and not 1.9.x?

You can use either one.
You probably can only mix 32 bit ruby with 32 bit Tcl/Tk distro.

Re: easier
did you see my comment about ""Ruby 1.8.6-p27 (RC2)""
or about a zip file that contains tk?

What comment? I've read everything in this thread. You mean the one that
says; "If you're interested in a 1.8.x that works with tk, see
http://rubyinstaller.org/downloads/"

I don't really want to use 1.8.x, that stupid tutorial told me to. Of
course I'd like to use the latest and greatest which is probably 1.9.x.


> or about a zip file that contains tk?

You mean this one you made?
http://faithpromotingrumors.org/inco...386-mingw32.7z

I'm installing 7 zip now to try it. I didn't want to use 1.9.x because
that tutorial told me to specifically compile the 1.8.x source but since
that tutorial was a total disaster I'm looking at using your 1.9.x and
that new tutorial below. The tutorial is nice but doesn't say how to
install ruby. Just about programming in the language. I need to get it
installed first and that is the hard part. You can compile from source
or use a "one click install" on windows. I'd rather compile from source
but can't get it to work. I also have a FreeBSD Unix machine that I can
use too but don't see any other tutorials about how to install ruby/tk
on that. I have no idea how to do it on Unix so I'm trying on windows
first. Actually, I did install ruby and Tcl/tk on my Unix box but
getting the same error. I need to know where to put the libraries and
how to get it to work.

Ok I've unzipped this thing now how do I install it? And what would I do
if you didn't make me this? I'd really like to get the original problem
fixed and figure out how to get the 1.8.x source compiled and working as
in that tutorial. I'd like to know how to get the proper files in the
right place and understand what I'm doing not "click one button and have
it magically work".

I don't want to start getting sidetracked. How can I build the 1.8.x
source properly with tk and avoid this error? That was my original
question. I also need to get this working on my Unix machine next (or in
parallel). As far as I know there is no "one-click installer" for that.
I need to know what goes where. Aren't there any install instructions
anywhere?

# Because I'm not familiar with development on Windows, the following
# may be wrong.

On Ruby/Tk, Ruby links tcltklib.so and links dynamic link librariies
of Tcl/Tk. If Ruby's core is a 32bit binary and Tcl/Tk DLLs are 64bit
binaries, Ruby cannot link Tcl/Tk DLLs.
It's not about OS, but consistency between an executable and DLLs.

Which version of ActiveTcl did you download?
If its platform is "Windows (x86)", it is 32bit version of Tcl/Tk.
But if you download "Windows (64-bit, x64)", then 64bit.

How does "ruby.exe -v" describe?
If it includes "x86-mswin32", then it is a 32bit executable.
Else if includes "x64-mswin64", then a 64bit.

If your Tcl/Tk is 64bit and your compiler can make 64bit binaries,
please try "--target=x64-mswin64" configure option.
If your compiler can make 32bit binaries only, please download and
install a 32bit version of ActiveTcl.

Actually I would like to get this fixed on my Unix machine too. I'm
getting this same error. I have tcl8.5.8 installed and Ruby 1.8.7. How
can I get it to work on Unix? Maybe if I get that working I'll
understand what I'm supposed to do on Windows.

gem install ffi-tk

That should work on any platform, be it 64bit, 32bit, windows, linux,
MRI, or JRuby.

The issue is that all existing tutorials are written with ruby-tk in
mind, some of the API is different.

Please tell me the directories of your Tcl/Tk headers/libraries, and
configure options which you gave at first step of compiling.
Probably, ext/tk/extconf.rb outputs some messages about searching and
testing Tcl/Tk libraries (and {tcl,tk}Config.sh) during make steps.
Please tell me the messages, too.
