Hi Dave,
Thanks for the reply after getting some sleep the question I should have asked is what
libraries do I need to link the application against? If I just try gcc -o a.out
hellolibvirt.c it can't find any of the libvirt calls.
[cc'ing the list again so the answer gets archived]
Libvirt's no different from any other library, you need to link
against libvirt, and you need to have the libvirt headers installed.
On Fedora, that's:
yum install libvirt-devel
If you want to build hellolibvirt without using make, you'll need to
edit hellolibvirt.c and take out config.h, which is unused. Then you
can do:
gcc -o hellolibvirt -lvirt hellolibvirt.c
Then you just need to learn the API and decide what you want to do
with it. ;-)
The API is documented at:
http://libvirt.org/html/libvirt-libvirt.html

Thanks,
Steve
