Ruby on Rails install problem

b-rod · 2011-03-10 02:28:21

I'm at the point in my RoR install where I'm executing a "bundle install" command. The install fails when it trys to install nokogiri 1.4.4. The error message reads "failed to build gem native extension". Any ideas as to why this gem is failing to install?

What version of ruby are you using?
ruby -v

I'm running ruby v1.9.2p180.

Here is the main area of the section of error message I receive after a bundle install command...

Using activerecord (3.0.5)
Using bundler (1.0.10)
Using diff-lcs (1.1.2)
Installing nokogiri (1.4.4) with native extensions /usr/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:533:in 'rescue in block in build_extensions': ERROR: failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

/usr/bin/ruby extconf.rb

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 many need configuration options.

Provided configuration options:
--with-opt-dir
--without-opt-dir

Nokogiri requires libxml2 and libxslt in order to compile. Do you have both installed?

  sudo pacman -S libxml2 libxslt

More info here

Yes I do have both libs installed...
libxml2 v2.7.8-1
libxslt v1.1.26-2

try

gem install --verbose --no-rdoc --no-ri nokogiri

see if you get any more informative error messages

gave me the same error messages as before (listed in previous reply). I think the problem might be that libxml2 and libxslt are not located in a place where nokogiri is looking when being installed therefore I'm getting the error messages. And I'm not sure what config options to pass when doing a "gem install nokogiri".

The page I linked to has a section near the bottom called "Nonstandard libxml2 / libxslt installations" which shows the config options to use.

Have you checked mkmf.log? It may contain a more specific error message.

b-rod · 2011-03-11 18:56:57

I used the config options listed in your previous link with the same error message results. My mkmf.log does not contain any error messages. I really don't know what to do next...I'll just have to keep on lookin'.

I had the same problem. It turns out that the Ruby "mkmf" library's pkg_config method (http://rubydoc.info/stdlib/mkmf/MakeMak … nce_method) will just silently say it can't find a library if the "pkg-config" program doesn't exist. It should probably just give an error if pkg-config doesn't exist. I just had to run "pacman -S base-devel", and that fixed the "checking for libxml/parser.h..." error.

Now, my latest ~/.bundler/tmp/*/extensions/x86_64-linux/2.1.0/nokogiri-1.5.9/mkmf.log is showing the following:
