[Tioga-news] Ruby patch failed on Tiger

[J.J. Fleck]

Hello everybody !


This email is not necessarily useful for the persons on the list who
hopefuly have a working version of the couple tioga/ruby but could be of
use for new users who whould be happy to find it in the archives.

It describes current problem to install tioga on Tiger (X.4) and a
solution.

It could perhaps be useful to change the concerned advices in the
installation page.

We have got some machines at the institute newly installed with MacOS
X.4.5 and as insterest in tioga is growing, it has to be installed also on
these machines.

I thus followed the link on the web page indicating to execute

curl -O rufy.com/fix-ruby-tiger.sh; sh fix-ruby-tiger.sh

unfortunately, an error occured in the last stage of the script
fix-ruby-tiger.sh when compiling readline:

Default compiler has been set to:
gcc version 3.3 20030304 (Apple Computer, Inc. build 1809)
checking for tgetnum() in -lncurses... yes
checking for readline/readline.h... yes
checking for readline/history.h... yes

        from extconf.rb:45

Looking into the file extconf.rb and commenting line 15 allowed to
continue and effectively do the Makefile and the compilation, but another
error occured

Looking more carefully into the source, it appeared that the downloaded
file was not ruby-1.8.2.tar.gz as specified on the page where the script
originate from but ruby-1.8.4.tar.gz. And the file ruby-1.8.2.tar.gz does
not exist anymore on the ftp server used... Parsing discussions about this
patch, it appeared that ruby-1.8.3.tar.gz or ruby-1.8.4.tar.gz are not
compiling where ruby-1.8.2.tar.gz did and so no chance to get ruby fixed
and tioga work (more exactly, irb version of tioga was working althought
not searching properly for ~/.irbrc, only for ./.irbrc but the GUI
interface stayed blanck without any error displayed..)

So if 1.8.2 is buggy and only patches for 1.8.4 available, why not
install ruby 1.8.4 ?

I found this page
http://www.servercodex.com/archives/2006/02/06/installing-darwinports-tiger/
which explain how to install darwinport (which is a tool somewhat similar 
to fink) on Tiger and explain as an example how to install ruby 1.8.4.

Once darwinport installed (using the link on the page), just type
sudo port install ruby
and ruby 1.8.4 get installed (after a while because compiling on the
machine). It even automaticaly install readline by itself. No need to
apply the patch anymore (but it would have to be checked on a new machine 
from scratch). Then a usual Tioga installation, in Tioga directory,
sudo ./QUICK_INSTALL
install properly what tioga needs and the GUI interface is perfectly
working (once the ruby PATH set to /opt/local/bin/ruby)


I hope it would be helpful for newbie users.


Cheers,
