Hi All, I tried to build using the 11C74.plist, an error occurred CoreOSMakefiles. I have made a build in three environments, all resulted in an error. (a) Mac OS X 10.6.3 + Xcode 3.2 (b) Mac OS X 10.6.8 + Xcode 3.2.4 (c) Mac OS X 10.7.2 + Xcode 4.2 How can I avoid this problem do? Thanks, HIWATASHI Kazuhiro -------------------- $ cd ~ $ mkdir 11C74 $ cd 11C74 $ sudo -s # darwinbuild -init 11C74 # darwinbuild xnu *** Attaching build root disk image ... /dev/disk1 GUID_partition_scheme /dev/disk1s1 EFI /dev/disk1s2 Apple_HFS /Volumes/BuildRoot_11C74_20120131163949 *** Fetching Sources ...
