pg gem encounters C extension support issues

it says..

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

            NotImplementedError: C extension support is not enabled. Pass -Xcext.enabled=true to JRuby or set JRUBY_OPTS or modify .jrubyrc to enable.

what should I do?

sqllite gem has the same crash..

this is how I solved

gem 'sqlite3'

—>

gem 'activerecord-jdbcsqlite3-adapter', :require => 'jdbc-sqlite3', :require=>'arjdbc'

I followed the advice in the error message and added the line

in the .jrubyrc file in my home folder (it didn’t exist, I had to create it).

Yes, I did similar to Hendie… I performed this

export JRUBY_OPTS="-Xcext.enabled=true"

bundle install --without production

Btw, you shouldn’t be getting issues with ‘pg’, but only with ‘sqlite3’, because you are running ‘—without production’ which will exclude the gem ‘pg’ line from being used. In any case if you use the bundle install—without production, you will get an error using sqlite3 which can be solved with either Hendie’s or my solution.
