I want to install in my Fedora 12 based planet lab nodes one OMF RC:
It requres ruby 1.9.3. So, I installed git, then ruby-devel then rvm. With rvm i installed:
rvm install 1.9.3
After all this when i want to install:
gem install omf_rc --pre --no-ri --no-rdoc
It gives me the following error:
Building native extensions. This could take a while...
ERROR: Error installing omf_rc:
ERROR: Failed to build gem native extension.
/usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb
checking for libxml/parser.h... * extconf.rb failed *
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers
Please let me know how to solve this. Thanks
seems you need to install libxml, try:
sudo yum install -y gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel
Also it needs the following installation:
sudo yum install -y git make gcc-c++
and
sudo yum groupinstall development-tools development-libs

what am i missing here?
From the error output, it would seem it can't find the development dependencies for Ruby, which Nokogiri is trying to use in order to build the gem natively.
You can run yum -y install gcc ruby-devel rubygems to make certain the dependencies are installed.
Basing my answer somewhat from https://stackoverflow.com/a/4502672/1129980
Update
Tested this now on a new EC2 instance:
yum install -y ruby23-devel gcc libxml2 libxml2-devel libxslt libxslt-devel patch
gem install nokogiri --no-ri --no-rdoc
That works :)
Try running the below mentioned commands
sudo yum -y install ruby-dev ( or ruby-devel)
sudo yum -y install libgmp-dev libgmpxx4ldbl ruby-dev ruby2.3-dev
I'm running Vagrant 1.8.1 on OSX 10.11.3 and I'm trying to install a plugin. While attempting to install I get the following the error:
vagrant plugin install vagrant-libvirt
............
An error occurred while installing ruby-libvirt (0.6.0), and Bundler cannot continue.
Make sure that `gem install ruby-libvirt -v '0.6.0'` succeeds before bundling.
.........
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
ruby-livirt 0.6.0 has already been installed:
# gem list | grep ruby-libvirt
# ruby-libvirt (0.6.0)
Can I bypass this error since the gem is already installed?
I had the same error while installing vagrant plugin install vagrant-libvirt it turned out that I was missing some libraries.
After installing below libraries on Ubuntu 16.04 I was able successfully install vagrant-libvirt plugin with vagrant plugin install command.
bridge-utils
build-dep
dnsmasq-base
ebtables
libguestfs-tools
libvirt-bin
libvirt-dev
libxml2-dev
libxslt-dev
qemu
qemu-kvm

Depends on your Linux distribution you might look at this link to find matching libraries.
I installed Ruby v2.1.4 from source. I installed all necessary libaries using:
yum install gcc g++ make automake autoconf curl-devel openssl-devel zlib-devel httpd-devel apr-devel apr-util-devel sqlite-devel

Now when I want to install a gem with:
gem install bundler-1.7.4.gem
I get:

Did I miss something?
I have found the solution at this blog. I am unable to use rvm because server have no internet connection even through proxy.
While installing ruby from sources doing the following solved the issue:
Remove the installed Ruby with make clean
Install libssl-dev with your OS's package manager of choice. E.g. apt-get install libssl-dev
Install zlib1g-dev with your OS's package manager of choice. E.g. apt-get install zlib1g-dev
Config make file to include openssl by go to ext/openssl and run ruby extconf.rb
Config make file to include zlib by go to ext/zlib and run ruby extconf.rb
Go back to ruby source code directory run make && make install
You should be able to successfully run gem install bundler
I'm installing the Ruby Nokogiri gem and finding the error below.
How to diagnose this and solve it?
# gem install nokogiri
Building native extensions. This could take a while...
ERROR: Error installing nokogiri:

from /opt/ruby/1.9.3-p194/lib/ruby/1.9.1/mkmf.rb:506:in `try_cpp'
...
To diagnose and solve, here's what worked for me.
To find out what failed, go to your ruby gems directory.
For example:
$ cd <MY RUBY DIRECTORY>/lib/ruby/gems/2.0.0/gems
If you don't know your gem directory, try this:
$ echo $GEM_HOME
/opt/gems/2.0.0
$ cd /opt/gems/2.0.0/gems
What version of nokogiri am I installing?
$ ls -ladg nokogiri-*
nokogiri-1.5.5
Go to the installer directory:
$ cd nokogiri-1.5.5/ext/nokogiri
Try installing manually:
$ ruby extconf.rb
Result:
checking for libxml/parser.h... *** extconf.rb failed ***
...
I'm using Ubuntu so I search for any similar packages:
$ aptitude search libxml
Results:
p libxml2 - GNOME XML library
p libxml2-dev - Development files for the GNOME XML library
...
I believe that libxml2 will work fine.
$ apt-get install libxml2
Ruby native gems often need the *-dev packages for headers so install them:
$ apt-get install libxml2-dev
Now do I have the parser file?
$ find / | grep libxml/parser.h
Yes, the result shows the parser:
/usr/include/libxml2/libxml/parser.h
Now try installing again, this time providing the libxml2 path:
$ gem install nokogiri -- --with-xml2-dir=/usr/include/libxml2
It still fails, so read the mkmf error log:
$ more mkmf.log
The error log shows what failed and has these lines that look promising:
package configuration for libxslt is not found
Is there a package for it?
$ aptitude search libxslt
Results:
v libxslt-dev
i libxslt-ruby
...
Install the dev package:
$ apt-get install libxslt-dev
Now try installing again, and also put xslt on the path:
$ gem install nokogiri -- \
--with-xml2-dir=/usr/include/libxml2 \
--with-xslt-dir=/usr/include/libxslt
Success!
Installing Nokogiri Website
'Installing Nokogiri' is a website dedicated to installing Nokogiri on the major platforms - Here is an excerpt about Installing Nokogiri on Ubuntu:
Because Nokogiri needs to be compiled and dynamically linked against
both libxml2 and libxslt, it has gained a reputation for being
complicated to install.
As of Nokogiri 1.6, libxml2 and libxslt source code is bundled with
Nokogiri, and compiled at gem-install-time. The instructions in this
document should work for all versions 1.6.4 and later.
Ubuntu / Debian
Installation should Just Work™ on Ubuntu and Debian using Nokogiri’s
vendored libxml2 and libxslt:
gem install nokogiri
[...]
Using Your System Libraries
If, instead of Nokogiri’s vendored libraries, you’d like to use your
system’s libxml2, libxslt and related libraries, please first
understand that you may be asking Nokogiri to work with an unsupported
version of libxml2.
sudo apt-get install pkg-config
gem install nokogiri -- --use-system-libraries
FYI - I am using Nokogiri 1.6.6.2 and it didn't 'just work'. I got it going with the --use-system-libraries.
Mac OS X
The website's advice also covers OS X - this worked for me:
gem update --system
xcode-select --install
gem install nokogiri
Conclusion
If you have a Nokogiri problem on any platform you should check out the website.
On CentOS here is what I needed to do:
gem update --system
yum install libxml2-devel libxslt-devel ruby-devel
gem install nokogiri -- --use-system-libraries
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.
You are probably missing zlib headers which are required for -lz flag in order to compile the sources correctly. Install on Linux by:
sudo apt-get install libz-dev
For missing libiconv, try installing libiconv-hook-dev package which has header files of libiconv-hook, e.g.
sudo apt-get install libiconv-hook1 libiconv-hook-dev
On OS X, try installing development tools via: xcode-select --install.
If there is still problem, check mkmf.log file for more specific details about your error.
On Ubuntu, try the following dependency fix combo:
sudo apt-get install gcc ruby-dev libxslt-dev libxml2-dev zlib1g-dev
The 'could not create Makefile' error you're seeing could also be because you haven't agreed to the Xcode license (you have to agree to it after each time you update Xcode). Running sudo xcodebuild -license accept should eliminate this error for you and allow you to then run gem install nokogiri successfully.
The Ruby on Rails website recommends installing Ruby from source under Linux.
I encountered a number of C library problems building ruby from source on a clean install of Ubuntu 9.
All the instructions I found on the net about installing ruby on Ubuntu have involved using the prepackaged (.deb-based) ruby. Clearly this isn't what the rails people recommend.
When I did a clean source build of ruby I found Rubygems failed to install because the zlib extension didn't work.
Two problems occur:
1) The zlib extension isn't built.
Solution:
i) ensure zlib is uncommented in the Setup file within the extn directory of the ruby source, and
ii) ensure these zlib ubuntu packages are installed:
aptitude install zlib1g
aptitude install zlib1g-dbg
aptitude install zlib1g-dev
aptitude install zlibc
2) After fixing Problem 1 above (and doing a clean rebuild of ruby), zlib still doesn't work because the extension fails to load.
You can see that the module fails to load by running this and getting the output "false":
puts require 'zlib'
I observed this happens to any number of other C extensions in the extn directory, so it appears to be a more general problem with these extensions than just something zlib-specific.
To summarize:
My build of ruby finds the ruby-specific C zlib extension but it fails to load the zlib module.
This behaviour appears to happen to other extensions in /extn.
Is there a way I can find out why a module fails to load? some kind of trace/verbose mode?
Here is what I did to install ruby, gems and rails on Ubuntu 11.04
Install ruby from sources
Install RubyGems from sources
Install zlib:
sudo apt-get install zlib1g-dev
cd your-ruby-sources/ext/zlib
ruby extconf.rb
make
sudo make install
Install readline:
sudo apt-get install libreadline5-dev
cd your-ruby-sources/ext/readline
ruby extconf.rb
make
sudo make install
Install openssl:
sudo apt-get install libssl-dev
cd your-ruby-sources/ext/openssl
ruby extconf.rb
make
sudo make install
I don't see what your problem is. You say that require 'zlib' returns false. But that means that it did work! If there were an error, you would get a LoadError exception.
Did you install libzlib-ruby? Here's my typical Ubuntu initialization before installing Rubygems:
$ apt-get update
$ apt-get dist-upgrade
$ apt-get install build-essential -y
$ apt-get install rsync -y
$ apt-get install ruby ri rdoc irb ri1.8 ruby1.8-dev libzlib-ruby zlib1g libopenssl-ruby -y
