Done. See the attached patch (apply it, then re-run autogen.sh and configure). It does three things: 1. Check if --disable-ipv6 was passed to configure. 2. Check to see if struct sockaddr_in6 exists. 3. Sets a macro OMPI_WANT_IPV6 to either 0 or 1 (i.e., it's always defined and is therefore suitable for #if, not #ifdef): - Set to 1 if --disable-ipv6 was not passed to configure *AND* struct sockaddr_in6 exists - Set to 0 otherwise So surround your code with: #if OMPI_WANT_IPV6 ...ipv6 stuff... #endif All you have to do to get this define is #include "ompi_config.h", which all of the files should be doing already, anyway. Let me know if this works for you. -- Jeff Squyres Server Virtualization Business Unit Cisco Systems
