Hello I'm trying to compile libvirt-0.8.6 on RHEL4 with kernel 2.6.9-67 The make command returns: -------------------- util/interface.c: In function `ifaceGetVlanID': util/interface.c:355: error: `GET_VLAN_VID_CMD' undeclared (first use in this function) util/interface.c:355: error: (Each undeclared identifier is reported only once util/interface.c:355: error: for each function it appears in.) make[3]: *** [libvirt_util_la-interface.lo] Error 1 make[3]: Leaving directory `/root/InstalledPackages/libvirt-0.8.6/src' make[2]: *** [all] Error 2 make[2]: Leaving directory `/root/InstalledPackages/libvirt-0.8.6/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/InstalledPackages/libvirt-0.8.6' make: *** [all] Error 2 -------------------- I have saw that GET_VLAN_VID_CMD should be in if_vlan.h file, but it is not present. What do I have to update in my system to avoid this error? Thanks in advance regards Antoni Artigues
