I am aware that anything above 10.4 is experimental and can cause issues, but something that doesnt make sense for me is that Alexander Thurgood is able to build against the 10.8 sdk. I am not understanding for me why on earth my build fails in cppunit. Does this mean there is a failing unit test somewhere? My autogen switches are as follows --with-macosx-sdk=10.7 --without-doxygen --enable-debug --enable-dgbutils --enable-symbols --with-system-openssl --disable-build-mozilla -- Jonathan Aquilina
