Installing sqlite3-ruby with rubygems on Ubuntu 8.0.4.1

Rails
1

Hi everyone,

I’m on Ubuntu Hardy and I just installed

ruby1.8
irb1.8
ri1.8
rdoc1.8
rubygems
ruby1.8-dev

I then intalled rails with rubygems and had to run the gem update
–system command once I wanted to create my first rails project,

I also have to install the sqlite3-ruby gem but each time I try to
here’s the error I get :

sudo gem install sqlite3-ruby
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 install sqlite3-ruby
checking for fdatasync() in -lrt… yes
checking for sqlite3.h… no

make
make: *** No rule to make target ruby.h', needed bysqlite3_api_wrap.o’. Stop.

Gem files will remain installed in
/usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4 for inspection.
Results logged to
/usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4/ext/sqlite3_api/gem_make.out

So I’m probably missing some libraries or maybe a environment variable,
could you please help me sort this out, I’d be enlightned

Cheers :slight_smile:

Agree! I see the problem with install gem sqlite3-ruby. This way help me
to fix it! Just install developer headers for provide compile the
library from sources.
SQLite3:

Without the -d option, rails will default to sqlite. To install SQLite3:

~$ sudo apt-get install libsqlite3-0 libsqlite3-dev
~$ sudo gem install sqlite3-ruby
