Hi, I’m trying to compile 32-bit Cygwin 2.0.2 from source on a clean installation of Cygwin, but I’m running into a problem – it won’t compile due to this error: c++wrap -O2 -g -fno-rtti -fno-exceptions -fno-use-cxa-atexit -Wall -Wstrict-aliasing -Wwrite-strings -fno-common -pipe -fbuiltin -fmessage-length=0 -MMD -Werror -fmerge-constants -ftracer -c -o net.o ../../../../newlib-cygwin/winsup/cygwin/net.cc ../../../../newlib-cygwin/winsup/cygwin/net.cc: In function ‘unsigned int if_nametoindex(const char*)’: ../../../../newlib-cygwin/winsup/cygwin/net.cc:2448:33: error: conflicting declaration of C function ‘unsigned int if_nametoindex(const char*)’ if_nametoindex (const char *name) ^ In file included from /usr/include/w32api/iphlpapi.h:170:0, from ../../../../newlib-cygwin/winsup/cygwin/net.cc:34: /usr/include/w32api/netioapi.h:374:29: note: previous declaration ‘NET_IFINDEX if_nametoindex(PCSTR)’ NET_IFINDEX NETIOAPI_API_ if_nametoindex (PCSTR InterfaceName); ^ ../../../../newlib-cygwin/winsup/cygwin/net.cc: In function ‘char* if_indextoname(unsigned int, char*)’: ../../../../newlib-cygwin/winsup/cygwin/net.cc:2481:47: error: conflicting declaration of C function ‘char* if_indextoname(unsigned int, char*)’ if_indextoname (unsigned ifindex, char *ifname) ^ In file included from /usr/include/w32api/iphlpapi.h:170:0, from ../../../../newlib-cygwin/winsup/cygwin/net.cc:34: /usr/include/w32api/netioapi.h:375:23: note: previous declaration ‘CHAR* if_indextoname(NET_IFINDEX, PCHAR)’ PCHAR NETIOAPI_API_ if_indextoname (NET_IFINDEX InterfaceIndex, PCHAR InterfaceName); ^ ../../../../newlib-cygwin/winsup/cygwin/../Makefile.common:43: recipe for target 'net.o' failed Examining the source for net.cc, I note the following comments at the top: /* FIXME: Collision with different declarations of if_nametoindex and if_indextoname functions in iphlpapi.h since Vista. TODO: Convert if_nametoindex to cygwin_if_nametoindex and call system functions on Vista and later. */ Huh? Further examination shows that there is indeed a conflict. But I examined the commit history in net.cc and it looks like nobody has changed anything related to this for years in that file. The comment itself is quite old. I'm a little amazed it's been working before. What am I missing here to get Cygwin building? One other minor quibble/note: I had to install texinfo package to get the build going; this isn't currently noted in the FAQ as a requirement.
