Tortured by the Dependency Daemons

The instructions for installation state, "In RWiki package for your
help, druby, ERb and MutexM have been installed on the `lib’ directory."
This was not true in my experience. Therefore, I attempted to install
all DEPENDENCIES, i.e.,“I did the best that I could.”. Afterward…

$ ruby -dv rwiki.rb

Resulted in the following error messages:

ruby 1.6.8 (2002-12-24) [i686-linux] Exception NameError' at /usr/local/lib/ruby/site_ruby/1.6/racc/parser.rb:24 - uninitialized constant Object::ParseError /usr/local/lib/ruby/site_ruby/1.6/rd/visitor.rb:78: warning: method redefined; discarding old visit_Reference ExceptionLoadError’ at

from /usr/local/lib/ruby/site_ruby/1.6/rwiki/rwiki.rb:13
from rwiki.rb:13:in `require’
from rwiki.rb:13

So, I re-installed strscan and also followed the optparse installation
instructions instead of what is stated in the instructions. Then…

$ ruby -dv rwiki.rb

Resulted in the following error messages:

ruby 1.6.8 (2002-12-24) [i686-linux] Exception NameError' at /usr/local/lib/ruby/site_ruby/1.6/racc/parser.rb:24 - uninitialized constant Object::ParseError /usr/local/lib/ruby/site_ruby/1.6/rd/visitor.rb:78: warning: method redefined; discarding old visit_Reference ExceptionLoadError’ at

from /usr/local/lib/ruby/site_ruby/1.6/rwiki/rwiki.rb:14
from rwiki.rb:13:in `require’
from rwiki.rb:13

I assume I need to install ERb properly. The instructions fail to help.
I obtained the most current version and installed it. Now…

$ ruby -dv rwiki.rb

Results in the following error message:

ruby 1.6.8 (2002-12-24) [i686-linux]
Exception `NameError’ at
/usr/local/lib/ruby/site_ruby/1.6/racc/parser.rb:24 - uninitialized

redefined; discarding old visit_Reference
/usr/local/lib/ruby/site_ruby/1.6/rd/labeled-element.rb:6: warning:

times)

Am I making any progress?

Hi, Jonathan…

The instructions for installation state, "In RWiki package for your
help, druby, ERb and MutexM have been installed on the `lib’ directory."
This was not true in my experience. Therefore, I attempted to install
all DEPENDENCIES, i.e.,“I did the best that I could.”. Afterward…

Sorry, I made the mistake. I included the obsolete document
into rwiki-2.0pre3. Please try with rd/install.rd of rwiki-2.0pre4.

Thank-you. An admission of an error seems to be a rare thing in the
computer programming world. Thanks for the reply.

I still am having a problem. It seems to start with Step 3 of RWiki
Installation

  1. Configure rw-config.rb using your favorite editor. (Comment: I am
    lost! If I ‘cp -pr lib/* /home/nahi/lib/ruby’ then what does this next
    step accomplish? It also help to see an example of what is to be
    configured.)

$ cd site
$ vi rw-config.rb

  1. Setup rw-cgi.rb as a CGI program.

$ cp interface/rw-cgi.rb ~/public (Comment: Does this directory already
exist? I have a /var/www/cgi-bin, can I use that directory or must I use
one labelled ~/public ?)
$ chmod 755 ~/public/rw-cgi.rb

  1. Configure rw-cgi.rb. Comment ‘SETUP’ must be configured. (Comment:
    What? I do not understand this instruction.)

  2. Check your ruby/1.6’s library search path. Is your personal library
    dir included? (ex. /home/nahi/lib/ruby)

$ ruby -e ‘p $:’

If not, exec either of below to set the search path. (Comment: Then why
have the reader create /home/nahi in the first place? Why not run ruby
-e ‘p $:’ after installing ruby, then use a directory that exists in the
path?)

$ cd site

Yes. You have to set up.

  1. Setup rw-cgi.rb as a CGI program.

$ cp interface/rw-cgi.rb ~/public (Comment: Does this directory already
exist? I have a /var/www/cgi-bin, can I use that directory or must I use
one labelled ~/public ?)
$ chmod 755 ~/public/rw-cgi.rb

“~public” is a example. Please read in accordance with
your environment.

  1. Configure rw-cgi.rb. Comment ‘SETUP’ must be configured. (Comment:
    What? I do not understand this instruction.)

Please edit the following three lines in rw-cgi.rb.

$KCODE = ‘EUC’ # SETUP
rwiki_uri = ‘druby://localhost:8470’ # SETUP
rwiki_log_dir = ‘/var/tmp’ # SETUP

  1. Check your ruby/1.6’s library search path. Is your personal library
    dir included? (ex. /home/nahi/lib/ruby)

$ ruby -e ‘p $:’

If not, exec either of below to set the search path. (Comment: Then why
have the reader create /home/nahi in the first place? Why not run ruby
-e ‘p $:’ after installing ruby, then use a directory that exists in the
path?)

Hmm…
Did someone succeed in installation of RWiki?
I want someone to help edit/write of a manual. Please edit this Wiki page.

Hello, again. We are communicating cross-culturally, so I think it is
easy to be misunderstood.

You seemed to have missed my point. I have no “site” directory. How can
I “cd site” in Step 3?

Yes, a site directory exists – where I unarchived the files prior to
installation – not where I have been installing the files according to
the previous steps. I fail to see how configuring rw-config.rb, in the
place where it exists, will help RWiki to run!

Not to worry about your English. It is sufficient. My Japanese would be
ludicrous.

I copied rwiki.rb and rwconfig.rb to the ~/lib directory and went
through reconfiguring the dependencies again.

I still get an error message:

It seems that the server has started.
Can you access your rw-cgi.rb page?

Hello, thanks for the reply. With all of those error messages I stopped;
I did NOT try to open rw-cgi.rb. I did notice that, rather than being
returned to the command line, it did seem at that point as if a process
was running. I will try and report the result.

Best regards,

Jonathan Smith

Today when I try to start the server, ‘ruby -dv rwiki.rb’, I get the
same error messages:

Following your question, I ignored the messages and tried to start CGI,
‘http://localhost/cgi-bin/rw-cgi.rb’

Hmm, when I try to load rw-cgi.rb into my web browser, I get the
following error message:

The server encountered an internal error and was unable to complete
your request.

 Error message:

Premature end of script headers: rw-cgi.rb

So, something works; it just does NOT work well enough.

I would appreciate your advice.

I again looked at rw-cgi.rb, rw-config.db and the installation
instructions. You refer to ‘druby://localhost:8470’. There is no druby
on my system; I have drb-2.0.0 Does this make any difference?

Probably, a library path is lacking.
Does rw-cgi.rb know your library path?
Please add following line to rw-cgi.rb

$:.unshift(’/home/your-home/your-lib’)

14

That fixed it! Thank-you.

I released RWiki2.0.
rd/install.rd was changed. Your correction is included in it.
Thank you, JWS.
