build failure against libxml2-2.9.0

Heads up!

When Fedora 18 is released, you're probably going to get a lot of people tripping over the libxml-ruby. That Fedora release looks set to ship with libxml2-2.9.0. When building libruby-xml-2.3.3 native extensions with that version of libxml2 installed, you get:

...
gcc -I. -I. -I/home/sheldonh/.rvm/rubies/ruby-1.8.7-p371/lib/ruby/1.8/x86_64-linux -I. -I/usr/include/libxml2 -I/usr/local/include -DRUBY_EXTCONF_H="extconf.h" -fPIC -O2 -fno-tree-dce -fno-optimize-sibling-calls -fPIC -I. -I/home/sheldonh/.rvm/rubies/ruby-1.8.7-p371/lib/ruby/1.8/x86_64-linux -I. -I/usr/include/libxml2 -I/usr/local/include -c ruby_xml_node.c
ruby_xml_node.c: In function ‘rxml_node_to_s’:
ruby_xml_node.c:622:54: error: dereferencing pointer to incomplete type
ruby_xml_node.c:624:56: error: dereferencing pointer to incomplete type
make: *** [ruby_xml_node.o] Error 1

Tested with ruby-1.8.7-p371 and ruby-1.9.3-p327 (using rvm), on a fresh Fedora 18 Beta x86_64 box with libxml2-2.9.0-3.fc18 and libxml2-devel-2.9.0-3.fc18 installed.

Hope that helps.

Ciao,
Sheldon.

Here's a work-around for rvm users:

rvm pkg libxml2
bundle config build.libxml-ruby
--with-xml2-lib=${HOME}/.rvm/usr/lib
--with-xml2-include=${HOME}/.rvm/usr/include/libxml2

The rvm pkg command can be run from anywhere. The bundle config should be run from the directory containing the Gemfile for the project on which you've run into this problem.

Then you can "bundle install" as normal.

Cool thanks, will provide an update.

This was fixed in the 2.4.0 release.
