The functions the linker complains about are freeaddrinfo and getaddrinfo. These functions are only used in sections inside #ifdef SUPPORT_IP6/#endif. So it seems you have the symbol SUPPORT_IP6 defined somewhere. You need to find out where that is defined. My guess would be: the file config.h. One possibility might be that you used the same sources on a non-Windows system where the file config.h was created? You may be able to remove the file config.h and rerun the cscript command. That should recreate the file. config.h is in the main directory (i.e. one up from the win32 directory where you need to build).

I deleted config.h, it was re-created by cscript, but problem still persists. acconfig.h says: /* Define if IPV6 support is there */ #undef SUPPORT_IP6 /* Define if getaddrinfo is there */ #undef HAVE_GETADDRINFO config.h.in says this (in 2 places) /* Define if IPV6 support is there */ #undef SUPPORT_IP6 configure has this (not sure if it's used on windows) ... [line 26531] #define SUPPORT_IP6 _ACEOF it seems IP6 support is turned off everywhere, do I need to pass a command line argument to turn off IP6 support? here is what configure.in says [line 498] dnl ***********************Checking for availability of IPv6******************* AC_MSG_CHECKING([whether to enable IPv6]) AC_ARG_ENABLE(ipv6, [ --enable-ipv6[[=yes/no]] enables compilation of IPv6 code [[default=yes]]],, enable_ipv6=yes) what command line switch should I use to turn off IP6? thanks in advance.
