Dear all, I tried to compile the xnu kernel according to steps in "Building the XNU kernel on Mac OS X 10.1.1" howto. I followed all the steps and when I typed "make" in xnu directory, error occured. It happened when /usr/bin/c++ tried to compile /xnu/iokit/Kernel/ IOLocks.cpp. The error is: cc1plus: Invalid option `-fapple-kext' Does that mean that I need to use a newer compiler? (the April beta developer tools?) If not, how to fix the problem? I am using the December Developer tools to compile the kernel. The version of xnu is the latest version from CVS on 18-May (tagged as "Apple- 267). thanks for your help.
