miketracy / wwmd Goto Github PK

I believe that its
gem install miketracy-wwmd
not
gem install mtracy-wwmd

This could be environmental, but here is the error I am getting:

Can't handle 1.9.x yet
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Any suggestions?

I'm running Mac OS X 10.5
I've been tracking a bug which makes irb crash with a BUS ERROR:

% irb
irb(main):001:0> require 'rubygems'; require 'wwmd'; page = WWMD::Page.new
/opt/local/lib/ruby/1.8/irb.rb:302: [BUG] Bus Error
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9]

After poking around I finally found the issue is the call to page.inspect irb is doing (irb --noinspect for instance doesn't crash).
So I ran the following program:
% cat foo.rb
require 'rubygems'
require 'wwmd'

page = WWMD::Page.new
page.inspect
% gdb --args ruby foo.rb
[...]
Program received signal EXC_BAD_ACCESS, Could not access memory.

So it seems to be crashing while calling inspect on the easy curl object.

What's strange is that the following works fine:
% irb
irb(main):001:0> require 'rubygems'; require 'curb'; c = Curl::Easy.new("http://www.google.co.uk"); c.inspect
=> "#<Curl::Easy http://www.google.co.u>"

I'm a n00b with ruby, so you will probably be faster that me debugging this issue.
