Question

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
