Subject: [ruby-talk:5021] Possible Ruby 1.6.0 Tk-related bug.




Hi,

First things first:

# ruby -v
ruby 1.6.0 (2000-09-19) [rs6000-aix4.3.2.0]

....
        cc -g  -I/driver/tools/src/ruby/ruby-1.6.0

The "make test" passed.

I built Ruby with Tcl/Tk 8.3.

Now for the major problem. When trying to run the (English version of the)
ruby-tk81-demos (same as the RAA version), any demo that had,

    require "tkafter"

did not display a window, although each demo kept the CPU very busy until
interrupted. When interrupted, the following output was displayed:

# ./widget
^C/usr/local/lib/ruby/1.6/tkafter.rb:316: Interrupt
        from ./widget:13:in `require'
        from ./widget:13

In each case, the line number corresponded to the require statement shown
above.

The good news is that other demos that don't use that require work, the
simplest example being hello,

========================
# cat hello
#!/usr/local/bin/ruby
require 'tk'

TkButton.new(nil,
        'text'=>"Hello Ruby world!",
        'font'=>TkFont.new('k14'),
        'command'=>proc{print "Hello Ruby world!\n"; exit}
).pack

Tk.mainloop
========================

(Actually, I had to remove the require 'tkencoding' statement from this
demo to stop a stack overflow; I'm not sure why I hadn't previously
removed it as I had done elsewhere, nor why I didn't previously see this
error.)
