[libvirt] One problem of libvirt for fc18.

Hi all, We are trying to compile libvirt on fc18. But it always reports such a problem with rpcgen. "make" fails: GEN lxc/lxc_monitor_protocol.h /usr/bin/rpcgen: C preprocessor failed with exit code 1 cannot shutdown /usr/bin/rpcgen: at ./rpc/genprotocol.pl line 124. make[2]: *** [lxc/lxc_monitor_protocol.h] Error 1 This should be the problem when executing rpcgen on fc18. [root@xxx libvirt]$ rpcgen --version rpcgen (GNU libc) 2.16 Any idea on how to resolve it or do a workaround? Thanks a lot. :) --Li
