RubyCocoa and libxml-ruby-0.3.6

Ruby
1

i have two versions of Ruby with my computer, the default Tiger one
(1.8.2) and another one installed in /usr/local

i’ve buil recently RubyCocoa using the ruby in /ur/local

however, within XCode when i print out ruby --version, i still get the
Tiger’s one (1.8.2)

then, following an advice given on RubyCocoa-talk i’ve installed also
libxml-ruby-0.3.6 for the Tiger’s ruby.

each time i put a “require ‘xml/libxml’” i my “rb_main.rb” file i get an
error saying this Tiger’s ruby is unable to find that extension.

in order to install libxml-ruby-0.3.6 for the Tiger’s ruby i had to
install also rubygems.

if i make a test, using Tiger’s ruby, from the command line i get no
error the libray is found.

it is only when wanting to use it from XCode, in a RubyCocoa app i get
this error.

any idae ???

Use DarwinPorts to install ruby which will put yet another ruby
in /opt/local/bin but this will be easy to keep updated, again with
DarwinPorts, then use DarwinPorts to install RubyCocoa. It puts
everything
where it should be.

i’ll try taht asap thanks :slight_smile:

I do, and it has worked very well… Although, I haven’t been able to
install libxml-ruby using RubyGems. It can’t find the libiconv installed
by DarwinPorts. When I have some time to write up my problem, I’ll post
it to the list.

I made a libxml-ruby portfile for DarwinPorts. It has been in
bugzilla for about 2 weeks – maybe I should start bugging them on
the mailing list. They also haven’t looked at my mod_ruby update (all
it does it update the version and md5 checksum).

i did a :

rm -rf /opt/local/lib/ruby/gems

followed by a :

~/Darwinports%> sudo port install rb-rubygems
—> Activating rb-rubygems 0.8.11_0
—> Cleaning rb-rubygems

then everything, up to now, worked fine.

Une,

Do you use any other ports? How many?

/opt/local is ONLY used by DP so you have the option of blowing
away /opt/local (sudo rm -rf /opt/local) reinstalling ports and then
reinstalling any ports you use.

On the issue of your scripts still finding /usr/bin/ruby, it is
necessary to
put in your .pofile in your home directrory “export
PATH=/opt/local/bin:/opt/local/sbin:$path”
This will make ports found first. If you use fink too do this AFTER you
call the fink script.

Good luck
john

unfortunately, this isn’t my case :wink:

because, before to darwinports i had allready installed rubygems into
/opt/local i get the following error message at the activate step :
—> Activating rb-rubygems 0.8.11_0
Error: Target com.apple.activate returned: Image error:

does not belong to a registered port. Unable to activate port
rb-rubygems.
Error: /opt/local/bin/port: Status 1 encountered during processing.

do you know some workaround ?

i not sure about that, having done a complete re-install of ruby,
rubgems and rubycocoa i still get from my rb_main.rb where i’ve put :

def rb_main_init
path = OSX::NSBundle.mainBundle.resourcePath.fileSystemRepresentation
rbfiles = Dir.entries(path).select {|x| /.rb\z/ =~ x}
rbfiles -= [ File.basename(FILE) ]
which_ruby=which ruby .chomp
p “#{which_ruby}”
p #{which_ruby} --version
p $LOAD_PATH
rbfiles.each do |path|
require( File.basename(path) )
end
end

the print out is :

“/usr/bin/ruby”
“ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]\n”

still Tiger’s ruby…

however the $LOAD_PATH is :
[“/Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/BookmarksM
erge.app/Contents/Resources”,
“/Library/Frameworks/RubyCocoa.framework/Versions/A/Resources/ruby”,
“/opt/local/lib/ruby/site_ruby/1.8”,
“/opt/local/lib/ruby/site_ruby/1.8/powerpc-darwin8.5.0”,
“/opt/local/lib/ruby/site_ruby”, “/opt/local/lib/ruby/vendor_ruby/1.8”,
“/opt/local/lib/ruby/vendor_ruby/1.8/powerpc-darwin8.5.0”,
“/opt/local/lib/ruby/vendor_ruby”, “/opt/local/lib/ruby/1.8”,
“/opt/local/lib/ruby/1.8/powerpc-darwin8.5.0”, “.”]

then again, again and again, ruby is tiger’s one even the $LOAD_PATH of
it is the corect one : /opt/local/blahblah…

exactly what i’ve get before using a “handy” install…

something wrong, to me, here !

no, only those related to ruby.

/opt/local is ONLY used by DP so you have the option of blowing

yes i know.

On the issue of your scripts still finding /usr/bin/ruby, it is necessary to
put in your .pofile in your home

i think you mean .profile ?
-------------------^-----

or, does exist a .portfile file ?
--------------------^^----

i think this has been done automatically by the Darwinports pkg :

cat .profile

Your previous .profile (if any) is saved as .profile.dpsaved

Setting the path for DarwinPorts.

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

directrory “export
PATH=/opt/local/bin:/opt/local/sbin:$path”
This will make ports found first. If you use fink too do this AFTER you
call the fink script.

no i don’t use fink.

BUT, i wonder about the useness of .profile, is this used by XCode ?
i don’t think so.
also, i’m using zsh instead of bash as a shell.
my $PATH is obviously starting by /opt/local/bin :

echo $PATH
/opt/local/bin:/usr/local/bin:/usr/local/mysql/bin:/bin:/usr/bin:/sbin:/
usr/sbin:/usr/X11R6/bin:/Users/yvon/bin:/Developer/qt/bin:/usr/local/pgs
ql/bin:/Users/yvon/bin/groovy/bin

my ruby scripts does have a shebang like that :

#!/usr/bin/env ruby -w

then, when launching a ruby script from Terminal i get the right ruby
according to the $PATH

all of those scripts are working correctly, from Terminal.

again, i don’t think XCode nor RubyCocoa use this way to find ruby (thru
$PATH)

Jonathan Paisley (on RubyCocoa-talk mail-list) said something like “ruby
cocoa don’t use /opt/local/bin/ruby” it finds that by $LOAD_PATH, which
is correct.

Finally may be it is MY way to print-out which ruby is in under use
being WRONG (from XCode /RubyCocoa) :
which_ruby=which ruby .chomp
p “#{which_ruby}”
p #{which_ruby} --version
p $LOAD_PATH

because i don’t know, in the XCpde/RubyCocoa context, what’s the SHELL
in use (i’ve set the $SHELL to /usr/local/bin/zsh.

to finish with, adding this line (after p $LOAD_PATH) in my rb_main.rb :
p ruby --version
i get :
“ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]\n”

now, i’ll try, before (re)+ installing ruby and co, try a libxml binder
install by gem.

Nope. It only affects what you get when you type “ruby” at the command
line.

I had the same problem. Somebody told me to use DarwinPorts, but
happily, I didn’t take their advice. The last thing I needed was yet
another install of Ruby in yet another location. I already had too many
installs as it was! {chuckle}

Look and see if you have too many RubyCocoa.framework files. I’ll bet
you’ll find one in /Library/Frameworks, AND one in
~/Library/Frameworks. Delete the one in your user Library, and XCode
should start finding the one you want.

Your making this much harder then needed. If you use DP to install
RubyCocca then the stuff that XCode uses goes in the correct developer
directories and the bindings go in /opt/local. This is all transparent
to
XCode! The need for the $PATH changes only have to do with using ruby
from
a shell.

This has been posted to both this list and the DP list.

install ruby with DP
install RubyCocca with DP
use RubyCocca in XCode

i agree very much with you, the ruby Darwinports install is worst than
the “hand made”.

the /opt/local/bin/gem is unable to find iconv (re-installed by dp) and
then fails to install ruby-libxml…

generally i avoid using dp nor fink…

i don’t have a ~/Library/Frameworks even.

The DP ruby applies several patches to ruby so you get a full working
install. If you are having trouble installing ruby-libxml through
rubygems, than download the tar.gz package, and run extconf with the
–with-iconv-dir=/usr option, or you can wait until darwinports
accepts my Portfile for libxml-ruby. Managing packages without the
use of a package manager is a pain in the ass.

i know that.

it’s what i have done yesterday afternoon, however i was unable to
install libxml-ruby :
sudo gem install -r libxml-ruby
fails to :
ERROR: While executing gem … (RuntimeError)
ERROR: Failed to build gem native extension.
Gem files will remain installed in
/opt/local/lib/ruby/gems/1.8/gems/libxml-ruby-0.3.6 for inspection.

even if iconv has been installed by dp…

then i’m BACK exactly at the point where i was before yesterday
afternoon, it is even worst because now i’m no more able to install
libxml-ruby which was the ONLY reason for me to make a new ruby install
with dp…

before that dp install i was able to use libxml-ruby from terminal,
RubyCocoa failed on “require ‘xml/libxml’”.

Both from a thread on the DP list and the experience of at least two
fellow
programmers, all those problems are due to trying to put DP Ruby /
RubyCocca on top of some installation of the same. If you blow
away /opt/local and all of the installed RC frameworks, (you did do a
check
of all files installed when you installed RC didn’t you?) then use DP
install ruby (which also creates a /opt/local tree with all the Ruby
libs
and then use DP to install RC, you are there. The parts of RC that
depend
on Ruby libs will find those because the are under the same /opt/local
tree. No need to seach for ruby-libxml or any other dependent library.
RC
will know where to find them.

Daniel,

I would strongly encouage you to do this. They are pretty good.
Looking at
the various threads I am seeing about 50 percent of people who fail in
the
install of RubyCocca with DP and all of them have to do with the
ruby-libxml stuff. I wonder why it is a some do some dont?

fine thanks it works* using :

ruby ext/xml/extconf.rb --with-iconv-dir=/usr
make
sudo make install

and right now i’ve uncommented “require ‘xml/libxml’” in my rb_main.rb
and i don’t have any more crash about that, however i must test that
more deeply, this require works also from Terminal…
