It does not result from > difference between cygwin-2.0.2-1 and cygwin-2.0.1-1. I have looked into this problem. The cause is as follows. netioapi.h in w32api-headers 3.3.0-2 was using a macro-name _INC_NETIOAPI for include-guard. By defining _INC_NETIOAPI, net.cc avoids including netioapi.h, which conflicts with if_nametoindex() and if_indextoname() in it. However, the macro-name for include-guard in netioapi.h of w32api-headers 4.0.2-1 has been changed to _NETIOAPI_H_. As a result, net.cc fails to avoid including netioapi.h, which causes confliction. Thus, defining _NETIOAPI_H_ in net.cc resolves the problem. diff --git a/winsup/cygwin/net.cc b/winsup/cygwin/net.cc index eaf6eb8..d6a631b 100644 --- a/winsup/cygwin/net.cc +++ b/winsup/cygwin/net.cc @@ -19,6 +19,7 @@ details. */ TODO: Convert if_nametoindex to cygwin_if_nametoindex and call system functions on Vista and later. */ #define _INC_NETIOAPI +#define _NETIOAPI_H_ #include "winsup.h" #ifdef __x86_64__ /* 2014-04-24: Current Mingw headers define sockaddr_in6 using u_long (8 byte) -- Takashi Yano <takashi DOT yano AT nifty DOT ne DOT jp> -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
