Thanks for libvirt. It is a life saver. I am in the process of writing some custom wrappers for libvirt so that it can be easily accessed from nodejs using the nodejs-ffi interfacing (basically describes a way to convert nodejs to c calls). I did write the wrapper on the lines of the examples provided. But I am unable to see my new functions in the libvirt.so file (which nodejs interfacing needs). Which means that my wrappers under <libvirt>/wrappers/ are not getting into libvirt.so like the ones at <libvirt>/examples
I don't quite get what you are doing. Why would you need to modify libvirt to wrap it in a nodejs-based script? What is that libvirt/wrappers folder you are mentioning? there is no such thing in the libvirt repository.
From what I understood from the nodejs-ffi page, you should mostly write javascript code similar to this:
------------ %< ------------ var ref = require('ref'); var ffi = require('ffi'); var virConnect = ref.types.void; var virConnectPtr = ref.refType(virConnect); var libvirt = ffi.Library('libvirt', { 'virInitialize': [ 'int', [ ] ], 'virConnectOpen': [virConnectPtr, [ string ]], ... }); ------------ %< ------------ I'm pretty sure generating this could be automated by a small program or script or even a clang plugin, using include/libvirt/libvirt.h.in as input.
Can you please guide me as to where I am going wrong? I was able to do a successful configure + make and I thought this will regenerate the new libvirt.so (which it does, but I cant see my new wrapper methods in it).
I case you really want to modify libvirt, then you should proceed as mentioned on this page: http://libvirt.org/compiling.html Regards, -- Cedric
