Hi Yang, All the newly defined posix constants are located in errno.h, located between line 91 and 132.

I've marked the conflicting lines with a C (hopefully, I've not missed any). /* * Portable error number symbolic names defined to Winsock error codes. */ #ifdef USE_WINSOCK #undef EBADF /* override definition in errno.h */ #define EBADF WSAEBADF #undef EINTR /* override definition in errno.h */ #define EINTR WSAEINTR #undef EINVAL /* override definition in errno.h */ #define EINVAL WSAEINVAL C #define EWOULDBLOCK WSAEWOULDBLOCK C #define EINPROGRESS WSAEINPROGRESS C #define EALREADY WSAEALREADY C #define ENOTSOCK WSAENOTSOCK C #define EDESTADDRREQ WSAEDESTADDRREQ C #define EMSGSIZE WSAEMSGSIZE C #define EPROTOTYPE WSAEPROTOTYPE C #define ENOPROTOOPT WSAENOPROTOOPT C #define EPROTONOSUPPORT WSAEPROTONOSUPPORT #define ESOCKTNOSUPPORT WSAESOCKTNOSUPPORT C #define EOPNOTSUPP WSAEOPNOTSUPP #define EPFNOSUPPORT WSAEPFNOSUPPORT C #define EAFNOSUPPORT WSAEAFNOSUPPORT C #define EADDRINUSE WSAEADDRINUSE C #define EADDRNOTAVAIL WSAEADDRNOTAVAIL C #define ENETDOWN WSAENETDOWN C #define ENETUNREACH WSAENETUNREACH C #define ENETRESET WSAENETRESET C #define ECONNABORTED WSAECONNABORTED C #define ECONNRESET WSAECONNRESET C #define ENOBUFS WSAENOBUFS C #define EISCONN WSAEISCONN C #define ENOTCONN WSAENOTCONN #define ESHUTDOWN WSAESHUTDOWN #define ETOOMANYREFS WSAETOOMANYREFS C #define ETIMEDOUT WSAETIMEDOUT C #define ECONNREFUSED WSAECONNREFUSED C #define ELOOP WSAELOOP #ifndef ENAMETOOLONG /* possible previous definition in errno.h */ #define ENAMETOOLONG WSAENAMETOOLONG #endif #define EHOSTDOWN WSAEHOSTDOWN C #define EHOSTUNREACH WSAEHOSTUNREACH #ifndef ENOTEMPTY /* possible previous definition in errno.h */ #define ENOTEMPTY WSAENOTEMPTY #endif #define EPROCLIM WSAEPROCLIM #define EUSERS WSAEUSERS #define EDQUOT WSAEDQUOT #define ESTALE WSAESTALE #define EREMOTE WSAEREMOTE #endif For what it's worth, I've voted up the Microsoft Connect issue. Your help is really appreciated. Don't hesitate if you need me to try an updated version of setup_once.h.

Don't take for granted that setup_once.h is the naive one here. Provide the list of redefined macros, which header defines them in first place and with which value and we'll adjust our headers to fix VS2010 brokenness. > Note 2: I've also encountered this problem with OpenSSL 1.0.0 (makes you > wonder whether I'm the only person that has tried compiling Curl and OpenSSL > on VC10 since the first Beta has been released). Others have similar problems with this issue. But MS seems sloooooooooooower fixing issues. http://connect.microsoft.com/VisualStudio/feedback/details/509380/errno-h-socket-return-codes-now-inconsistent-with-wsagetlasterror Even when it isn't actually a libcurl problem, we try to do our best in providing a library and tool that can be compiled with nearly any f*****g compiler version. So tell us the info i've requested above in order to make libcurl compilable out of the box even with VS2010. -- -=[Yang]=- ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
