[libvirt] Latest git tree doesn't compile

[Florian Vichot]

Hello everyone,

I just got the latest and grooviest libvirt from the git tree at :
git://git.et.redhat.com/libvirt.git
but compiling fails:

/bin/bash ../mylibtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I.
-I.. -I../gnulib/lib -I../gnulib/lib -I../include -I../include

lxc_container.c: In function 'lxcContainerDropCapabilities':
lxc_container.c:657: error: 'PR_CAPBSET_DROP' undeclared (first use in
this function)
lxc_container.c:657: error: (Each undeclared identifier is reported only
once
lxc_container.c:657: error: for each function it appears in.)

Apparently, my machine doesn't have the PR_CAPBSET_DROP flag defined.
It's inexistent in sys/capability.h and "man prctl".

I run a Ubuntu 8.04, kernel is 2.6.24-24-openvz.

Am I missing headers that are not tested for in the ./configure ? If
not, any way that functionality could be disabled on distros that don't
support it ?

Thanks,
Florian
