Is anybody else having this problem:
When I try to build cvsnt, I get errors while compiling
mdns_apple.cpp due to confliciting definitions of constants:
> apple/mdns_apple.cpp:36: error: conflicting declaration
> 'kDNSServiceClass_IN'
> /usr/include/dns_sd.h:144: error: 'kDNSServiceClass_IN' has a
> previous declaration as '<anonymous enum> kDNSServiceClass_IN'
> apple/mdns_apple.cpp:37: error: conflicting declaration
> 'kDNSServiceType_A'
> /usr/include/dns_sd.h:149: error: 'kDNSServiceType_A' has a

> 'kDNSServiceType_AAAA'

Sure enough, the source file contains this definition:
> #ifdef __APPLE__
> // Bizarrely, OSX doesn't define these...
> enum

> kDNSServiceClass_IN = 1, /* Internet */
> kDNSServiceType_A = 1, /* Host address. */
> kDNSServiceType_AAAA = 28, /* Ip6 Address. */
> kDNSServiceType_SRV = 33, /* Server Selection. */
> };
> #endif
However, in my system configuration (Mac OS X 10.4.7, Xcode 4.1), /
usr/include/dns_sd.h DOES contain the constant definitions, so these
are duplicates, which gcc-4.0 doesn't seem to like a lot...
So far I've been working around this by disabling mdns support, but I
really think this should be solved somehow by either conditionally
defining the constants in mdns_apple.cpp only if it's not defined by
the system (would need some macro to test for, either from the system
headers, or defined from the configure script, both of which I have
no idea about) or, alternatively, require the latest SDKs for
building csvnt (also probably not the perfect solution).
Since I'm using the "build-mac-multi" script in the osx directory, I
wonder whether anybody else is having the same problem.
