debian ruby libraries

[Zach Dennis]

I've got a few directories with ruby libraries.

/usr/lib/ruby/1.8
/usr/local/lib/ruby/1.8

I am on a debian package and I installed "apt-get install libmysql-ruby1.8".
It installed the mysql.so file into the /usr/lib/ruby/1.8/i386-linux/
directory. When I run irb or ruby it doesn't appear to be looking there.
Instead it looks in the /usr/local/lib/ruby/1.8 directory. Any quick and
easy change to get ruby to look in the proper directory or to tell debian to
install to the proper directory? Thanks,

Zach

What version of ruby are you running?

$ locate mysql.so
/usr/lib/ruby/1.6/ia64-linux/mysql.so
/usr/lib/ruby/1.8/ia64-linux/mysql.so

$ dpkg -l irb ruby1.8
Desired=Unknown/Install/Remove/Purge/Hold

||/ Name Version Description

$ irb
irb(main):001:0> require 'mysql'
=> true
irb(main):002:0> puts $:.join(', ')
/usr/local/lib/site_ruby/1.8, /usr/local/lib/site_ruby/1.8/ia64-linux, /usr/local/lib/site_ruby, /usr/lib/ruby/1.8, /usr/lib/ruby/1.8/ia64-linux, .
=> nil

Instead it looks in the /usr/local/lib/ruby/1.8 directory.

Do you have mysql.so there? Do you have $RUBYLIB set to look there
before the predefined paths? Are you explicitly setting $: in your
scripts? Those are the only things I can think of that could cause
this, since /usr/local/lib/ruby/1.8 is not in $: by default in
ruby1.8.

Any quick and easy change to get ruby to look in the proper
directory or to tell debian to install to the proper directory?

Debian is installing it in the proper directory; why you're not
looking there is a good question, though.
