This I don't understand, as this isn't exactly new code. The warning in error.h:172 has been in the source tree since September 2005. I suspect this to be somehow compiler related. I'm compiling OpenVPN regularly on Fedora 14, which uses: $ gcc --version gcc (GCC) 4.5.1 20100924 (Red Hat 4.5.1-4) > socket.c: In function 'create_socket_udp6': socket.c:902: error: > 'IPV6_RECVPKTINFO' undeclared (first use in this function) > socket.c:902: error: (Each undeclared identifier is reported only > once socket.c:902: error: for each function it appears in.) make[4]: > *** [socket.o] Error 1 This seems to be the main reason why it chokes. I've Cc'ed Juan Jo, who introduced this change. It's related to the new IPv6 transport feature.

Agreed, there is something odd going on here. But I don't have any OSX boxes available and lack some knowledge about the OSX build environment, so it's really hard to figure out immediately. I hope others with OSX can have a look at what's causing this. kind regards, David Sommerseth -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9E9/YACgkQDC186MBRfrrUdgCbB3IL4kKjMgryggfqSwhjcKap wF4AoKR6WXY9dp/SEBFZS8wow/tPv49L =w4Eu -----END PGP SIGNATURE-----
