I'm seeing:
/usr/bin/ld: libvirt_lxc-domain_conf.o: undefined reference
to symbol 'log2@(a)GLIBC_2.2.5'
when building the git HEAD just now.
It appears to be the result of:
aa14709a src/conf/domain_conf.c (Matthias Bolte 2011-07-11
19:29:09 +0200 5868)
virDomainVirtTypeToString(log2(expectedVirtTypes)));
I don't have time to look into it, but thought I should mention it.
