[chef] Re: Re: Re: Re: ruby-pg gem won't compile

[Marcelo de Moraes Serpa < >]

Just a heads up on what worked for me. I didn't have to modify the postgresql cookbook, the problem was really with the Ruby distribution that Chef was using.

I started using this cookbook - [https://github.com/map7/chef-solo/tree/master/cookbooks/ruby_installer] - to install Ruby 1.9.3-p317 system wide (that means that Chef is using it too. I tried using rvm but it's just a pain in the *ss on production systems, it seems).  and now the ruby-pg gem compiles when bundler install is called for my Padrino application. Everything is working great now :)

Hope that helps someone,

Cheers,

- Marcelo.

Hi Torben,

Thanks for sharing that! I'll try that out.

Nope, not manually. I have update my postgresql::client recipe like so to install from source when we are on an ubuntu 12.04 omnibus install:

@torben, thanks. I have seen this workaround, but  wanted to try something else. Any way to include that in the cook process? Or did you run it manually? I wouldn't want to have to run it manually though, since that pretty much defeats the purpose of Chef.

@edward - that pretty much means I'll have to hack into the postgresql-server recipe right? I'll play with it.

Lastly, does anyone know why this still fails? This is a pretty critical bug for such an important cookbook. 

Thanks!

- Marcelo.

It'll be looking for libpq in some set of library paths - but your libpq isn't in one of those paths.
Find libpq - figure out what library paths it's using (it probably tells you at the top) and then put the two together.
You could symlink the library or add a library path when running the configure.

cheers,

Hi list,

I've had some success with Chef (solo) so far, using knife-solo. I could already provision a server with nginx and a jekyll blog...

However, I got lost when it came to setup my rack app (padrino). I'm writing my own recipe, like I did with the jekyll one, and using a couple of other recipes for other components (postgres, runit, unicorn, application, application-ruby).

Everything goes well until I reach the point where bundle install tries to install the ruby-pg gem for the padrino app. It fails with:

Installing pg (0.14.1) with native extensions 

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

Could not create Makefile due to some reason, probably lack of

details.  You may need configuration options.

 I have libpq installed, but it just doesn't pick it up. I tried the chef-rvm cookbook (https://github.com/fnichol/chef-rvm), and tried to install rvm on the deploy user (I'm creating a deploy user that the app should be deploy on and ran from), but it also doesn't pick it up, and the gem_package monkeypatch, that is supposed to allow gems to be installed in the rvm ruby, fails.

I'm totally lost. Could someone shed some light on it? I'd be grateful!

Cheers,

- Marcelo.
