I am learning how to use ruby from the book, 'beginning ruby, novice to
pro...' The chapter on using ruby with sql requires that I install
sqlite3-ruby.

Using sudo gem install sqlite3-ruby, I got the following--

Building native extensions. This could take a while...
ERROR: Error installing sqlite3-ruby:
ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb
checking for sqlite3.h... no
sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path
(the
location where your sqlite3 shared library is located).
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/bin/ruby1.8
--with-sqlite3-dir
--without-sqlite3-dir
--with-sqlite3-include
--without-sqlite3-include=${sqlite3-dir}/include
--with-sqlite3-lib
--without-sqlite3-lib=${sqlite3-dir}/lib


Gem files will remain installed in /var/lib/gems/1.8/gems/sqlite3-1.3.3
for inspection.
Results logged to
/var/lib/gems/1.8/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out

going into irb,

require 'rubygems'
=> true
require 'sqlite3'
no such file to load -- sqlite3 (LoadError)

What went wrong?

*my pc is on ubuntu 11.04. I checked synaptic package manager and see
that sqlite3 is installed.

You need libsqlite3-dev, which will provide sqlite3.h.

Thanks for that quick reply.

I looked up and installed libsqlite3-dev in synaptic package manager.
Running irb...

require 'sqlite3'
=>
LoadError: no such file to load -- sqlite3
from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'
from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require'
from (irb):2
from /usr/lib/ruby/1.8/rubygems.rb:123

Unfortunately, you'll have to build the gem again, since gem and apt are
separate package systems. Try this again:

gem install sqlite3

running--

gem install sqlite3

I got the following message--

ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /var/lib/gems/1.8
directory.

so I tried--

sudo gem install sqlite3

and got the following--

Building native extensions. This could take a while...
Successfully installed sqlite3-1.3.3
1 gem installed

found this on google-- http://goo.gl/2zcza gave it a try and got these--

################################################## #####

Hello! The sqlite3-ruby gem has changed it's name to just sqlite3.
Rather than
installing `sqlite3-ruby`, you should install `sqlite3`. Please update
your
dependencies accordingly.

Thanks from the Ruby sqlite3 team!

Yeah, that's what I meant

So, does your original code work now?

irb--

require 'rubygems'
=> true
require 'sqlite3'
=> true

I think everything works now. Thank you for your help--I appreciate it!
