[Libvir] Ruby bindings for libvirt

Hi, I am exploring the possibility of creating ruby bindings for libvirt. The only attempt I found after some searching is this: http://www.cs.ucsb.edu/~ckrintz/racelab/jisha/ Following the SWIG method as described in the above URL, I have gotten to the following point: [root@dell1 libvirt_ruby]# irb irb(main):001:0> require 'libvirt_ruby' => true irb(main):002:0> conn = Libvirt_ruby.virConnectOpenReadOnly("") => #<SWIG::TYPE_p__virConnect:0x2aaaaabc46c8> irb(main):003:0> dom = Libvirt_ruby.virDomainLookupByID(conn, 0) => #<SWIG::TYPE_p__virDomain:0x2aaaaabb5df8> irb(main):004:0> ret = Libvirt_ruby.virDomainGetInfo(dom, info) NameError: undefined local variable or method `info' for main:Object from (irb):4 irb(main):005:0> I am not sure how to create and pass in a ptr to a virDomainInfo struct object into the virDomainGetInfo call within ruby. Note that I was trying to following the info1.c example on the libvirt website: http://libvirt.org/examples/info1.c As you can tell, this is the first time I am trying to create any sort of language bindings for a C library. Some questions: 1. Is there a better way of creating ruby bindings for libvirt besides SWIG? If so, any pointers on what should be done? 2. Alternatively I can try to make my ruby code use libvirt-python bindings as a python library. Has anyone done so? Any problems with this approach? cheers, mengkuan
