Hello again,
Browsing a bit more I stumbled on a suggestion to install yet another gem:
postgres. This gem doesn't even install:
$ gem install postgres
Fetching: postgres-0.7.9.2008.01.28.gem (100%)
Building native extensions. This could take a while...
ERROR: Error installing postgres:
ERROR: Failed to build gem native extension.
/home/desousa/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb
extconf.rb:4:in `<main>': uninitialized constant Object::PLATFORM
(NameError)
Gem files will remain installed in
/home/desousa/.rvm/gems/ruby-1.9.2-p290/gems/postgres-0.7.9.2008.01.28 for
inspection.
Results logged to
/home/desousa/.rvm/gems/ruby-1.9.2-p290/gems/postgres-0.7.9.2008.01.28/ext/gem_make.out
What's the issue with this particular gem?
So far I tried 3 different gems for postgres adapter, each recommended at
different places on the web. Is there an "official" Rails gem for postgres?
Or an "official" adapter install guide?
Thank you,
Luís
