Based exclusively on work by Eric Blake in a patch posted with the
same
subject. However some modifications related to comments and my plans to
add another backend.
Added WITH_INTERFACE as the only automake variable deciding whether to
build the driver and using WITH_NETCF to identify that we're wanting to
use the netcf library as the backend.
In general I think it's good to separate the concept of the interface
driver from its netcf backend (regardless of what other backends we may
end up putting in.
I did notice that if I specify --with-netcf --without-interface, there
was no error, but instead the "netcf: " line at the end of configure
said "-lnetcf", implying that it might end up being added to the link
lines somewhere even though it also said "Interface: no". It think if
with-interface == no, then with-netcf should also be set to no (or an
error generated if it's being forced to yes, since there's no other use
for netcf).
Beyond that, I will have to defer to Eric's superior knowledge of
autoconf for any more detailed comments about the changes to configure.ac.
* configure.ac: Added with_interface
* src/interface/netcf_driver.c: Renamed..
* src/interface/interface_backend_netcf.c: ..to this to match storage.
* src/interface/netcf_driver.h: Renamed..
* src/interface/interface_driver.h: ..to this.
* daemon/Makefile.am: Respect WITH_INTERFACE and WITH_NETCF.
* libvirt.spec.in: Add RPM support for --with-interface
