[darwinbuild-dev] darwinbuild mDNSResponder fail to build

[Yoann Gini]

Hello,

It’s my first message here so let me introduce me as first.

I’m a french apple certified trainer and consultant who work in freelance. I’m also a OS X and iOS developer (and I lead some training on this subject). I've writing some french article about OS X Server like Password Server external commands, Wide Area Bonjour, etc.

I’m here for the last one. Bonjour Wide Area. Since 10.6.3, dnsextd (a subpart of mDNSResponder who handle the server side of WAB system) is broken. I’ve made some bug report about it but without any answer. A lot of people who try to use WAB fallback on my article and drop me a mail to got help. Actually, I send back a old version of dnsextd (10.6.0) who work well. But I would like to understand what change they have between these two version and why it’s broken today.

So I’ve try to compile mDNSResponder package with darwinbuild, and here I’m… I’m unable to compile it, maybe I could get some help here.

I’ve installed darwinbuild from Mac Ports on OS X Lion, I’ve the last release of Xcode.

As root, I’ve initialize a folder with « darwinbuild -init 10B504 » in « /DarwinBuild/10B504 » then I’ve try to make « darwinbuild mDNSResponder »

The system seems to work, it has pass some hours to download an build many things to end with a error and I don’t understand why. If someone can help me…

Sorry for the size of these dump, I don’t really know what should be useful at these moment :

Build log begins here:
