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:
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 have it in /usr/include/linux/prctl.h #define PR_CAPBSET_DROP 24
I run a Ubuntu 8.04, kernel is 2.6.24-24-openvz.
2.6.24 is probably too old I see the patch from Nov 2007 http://lkml.indiana.edu/hypermail/linux/kernel/0711.3/0496.html
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 ?
We could possibly make the #ifndef / #endif and let the call fail if someone used the driver instead of breaking at compile time.
