Hi, I'm not sure which package to blame about this problem, except at least keepalived itself, which wants "low level" access to kernel includes. This is the real world problem : https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=228544#c7 It doesn't happen on RHEL4 or FC6, only on Fedora development. Could this be some kind of de-sync between defines in the headers provided by glibc-headers and kernel-headers packages? Even after "forcing" keepalived to not go and include headers from the kernel-devel package, I still get errors like this : In file included from /usr/include/net/ethernet.h:26, from ../include/vrrp_arp.h:29, from vrrp_arp.c:29: /usr/include/sys/types.h:62: error: conflicting types for 'dev_t' /usr/include/linux/types.h:13: error: previous declaration of 'dev_t' was here /usr/include/sys/types.h:67: error: conflicting types for 'gid_t' /usr/include/linux/types.h:27: error: previous declaration of 'gid_t' was here /usr/include/sys/types.h:72: error: conflicting types for 'mode_t' /usr/include/linux/types.h:15: error: previous declaration of 'mode_t' was here /usr/include/sys/types.h:77: error: conflicting types for 'nlink_t' /usr/include/linux/types.h:16: error: previous declaration of 'nlink_t' was here /usr/include/sys/types.h:82: error: conflicting types for 'uid_t' /usr/include/linux/types.h:26: error: previous declaration of 'uid_t' was here Should I file this as a bug? If yes, against glibc or kernel?
