installing extmath on MAC OS X

[Van Jacques]

MAC OS X comes with ruby installed (v.1.6.7), which is nice.
I am trying to install Jupp's extmath package on my machine,
and am having some problems.
(Note that even if you are the system admin. for your MAC(s),
you must use sudo to install anything.)

After installing extmath successfully, I tried to run test.rb,
and got the following error message:

test.rb:1:in `require': No such file to load -- runit/testcase (LoadError)
from ./test.rb:1

The first line of test.rb is

require 'runit/testcase'

Suggestions?

missing. My suggestion is that you download and compile the Ruby 1.8
source so that you get a complete and up-to-date Ruby installation.
Also, I'm sure that there is a binary Ruby 1.8 installer for OS X
available somewhere (although compiling Ruby from source actually is
very easy).

Hi!

[Ruby 1.6.7 on Mac OS X fails to run testcase]

Suggestions?

Install RubyUnit.

Note to myself: Add information that for running testcases either Ruby
1.8 or installation of RubyUnit is required.

Please bear with me, as my UNIX is extremely basic, and this
is the first time I have installed anything. I would
like to upgrade to 1.8 when I am competent enough.

A couple of questions.
--------
Here is my output from running test.rb from the
extmath-2.3 package.

-------
the so-dir is
/usr/lib/ruby/site_ruby/1.6/powerpc-darwin6.0
It's an empty directory.
The INSTALL doc from extmath-2.3 says that so-dir
is the directory for ruby extentions. Does this mean
that extmath.rb and rubyunit.rb (and runit) should be in the
powerpc-darwin6.0 dir? Or are they in the right place.
If so, why the error messages when running test.rb
from extmath-2.3?

<OT>OS X has a root account just like any other *nix, but root login is
disabled by default. Running "sudo passwd root" will enable root login,
so that you won't need to run sudo. <OT>

Maybe this is the source of my latest problems (see the other thread on this).
And thanks for the info on sudo. I think you are right about ruby 1.8
for OS X--I'll post here if I find it, and I will install the complete
1.8 version and see what happens.

I just tried "sudo passwd root"

and got

[jacques-computer:~] sylvanjacques% sudo passwd root
Password:
root: No such file or directory
0.00 real 0.00 user 0.00 sys
---
where passwd was my password. I then did it with the word "passwd"
and got

[jacques-computer:~] sylvanjacques% sudo passwd root
Changing password for root.
New password:
Password must be at least 5 characters long.
New password:
Retype new password:

So I changed my password--my old one was only 4 characters long.
I don't know if this enable root login though. I will find out later.
BTW, I have OS 10.2.8.

Mince alors !

You are right. There are several functions new in 1.8 that I use. I
don't have 1.6 so I didn't notice that :-|

Sorry, you will have to upgrade to 1.8 to use extmath (which in any
case makes sense because 1.6.7 not even the most recent 1.6 branch
version).

What does the double // mean in the path name?

Nothing. It is equivalent to just having one slash.

Rich Kilmer has a very good step-by-step guide on how to retrieve the
latest cvs version of Ruby and compile it. Even though it's focused on
10.3, it should apply just fine on 10.2.x as well.
