Hi,
Resiprocate-1.4 RC1 does not compile out of the box from SVN on
Windows with Visual Studio.
The problem is inconsistencies between the preprocessor constants
USE_IPV6 and IPPROTO_IPV6. The former is set in all project files
whereas the latter is defined nowhere.
As I understand it enabling USE_IPV6 only makes sense, when
IPPROTO_IPV6 is defined. Wouldn't it be possible to completely drop
one of those constants and only use the other?
IPPROTO_V6 is defined by the operating system, while USE_IPV6 is defined
by the build system. It would be quite reasonable to build on an
operating system that supports IPv6, but build a library that does not.
In other words, they really mean very different things, and can't be
combined.
That said, I think it would be reasonable to re-cast the "#ifdef
USE_IPV6 ... #endif" blocks to look something like:
#ifdef USE_IPV6
#ifndef IPPROTO_IPV6
#warn IPv6 support requested, but IPPROTO_V6 undefined
#else
...
#endif
#endif
