[libvirt] broken OpenBSD <net/if.h> [was: [PATCH] Include some extra headers needed for OpenBSD.]

Which OpenBSD extension function is triggering this warning? According to POSIX, this .c file should compile: #define _POSIX_C_SOURCE 200809L #include <net/if.h> #include <sys/socket.h> struct if_nameindex i; and it might just compile on OpenBSD (I haven't checked myself); the difference is that we have explicitly asked for namespace pollution beyond what _POSIX_C_SOURCE guarantees, which may explain why 'struct sockaddr' is interfering. But since <net/if.h> is required to be self-contained when in a strict environment, it makes sense for it to also be self-contained in an extension environment. It sounds like gnulib should consider providing a replacement <net/if.h> function to work around this lameness. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
