One caveat, mDNSResponder has to be built and deployed (using step 1 and 2 below) before it can be attached to Xcode.\ +\ +1.) First you have to build the Xcode project with symbols included and optimizations off.\ +\ + a.) From Terminal shell, open mDNSResponder Xcode project from top of tree: \'a0\ +\ + $ open mDNSMacOSX/mDNSResponder.xcodeproj/\ +\ +\pard\pardeftab720\partightenfactor0 +\cf0 You can also just double click on the project from Finder.\ +\ + b.) Add your diffs to mDNSResponder project. +\f1\fs22 \ +\pard\pardeftab720\partightenfactor0 + +\f0\fs24 \cf0 \ + c.) Set Strip Linked Product to No and compiler Optimization Level to None.
