Hello, I get this error when trying to build Keepalived 1.2.1 on a CentOS-4 box: # gcc -g -O2 (..) -D_WITH_LVS_ -D_WITH_VRRP_ -c smtp.c In file included from ../include/vrrp.h:31, from ../include/smtp.h:34, from smtp.c:27: ../include/vrrp_ipaddress.h:32:27: linux/if_addr.h: No such file or directory In file included from ../include/vrrp.h:31, from ../include/smtp.h:34, from smtp.c:27: In a CentOS-5 box 'linux/if_addr.h' file is owned by "kernel-headers" package and I can build Keepalived 1.2.1 without problems, but in CentOS-4 there is no such file, how can I solve this? thanks!
