    You may have encountered an error pointing to anv xnu kernel. There are several ways to solve this problem, which we will talk about shortly. g.XNU is a cross-type kernel that combines the Mach kernel from Carnegie Mellon University with components from FreeBSD, while using a C ++ API to write drivers called IOKit. XNU runs on I386, X86_64 for each of these uniprocessor and multiprocessor configurations.

     content:A. How to create XNUB. How to install a new header file from XNU================================================A. To create XNU:1) "do" type: creates all the components for working with the kernel, architecture and machine.  Configurations defined by TARGET_CONFIGS. We also support  Architectures defined in ARCH_CONFIGS and kernel controls defined in  KERNEL_CONFIGS. Pay attention to TARGET_CONFIGS, which overwrites all defined configurations.  on ARCH_CONFIGS and KERNEL_CONFIGS. In case of non-payment, the default building device will be architecture.  The architecture and configuration of the kernel is considered to be for DEVELOPMENT.    It also creates a very bootable mach_kernel image and kernel binary.  with symbols, mach_kernel.sys./ * This should be all you need to do to get us started RELEASE kernel build * /make X86_64 target_configs = "default release" SDKROOT = / path / to / SDKor the following is very close (omitted SDKROOT used /)make ARCH_CONFIGS = X86_642) Create DEBUG  Set the kernel config to DEBUG in your environment or when starting a brand new one  Make an order. Then ask for procedures 4, 5  $ make TARGET_CONFIGS = "X86_64 DEBUG All Standard "or  Earn money KERNEL_CONFIGS = DEBUG ARCH_CONFIGS = X86_64 all  Where  Export money TARGET_CONFIGS = "DEFAULT X86_64 DEBUGGING"  buck export SDKROOT = / path / to / SDK  $ do everything  Example:    $ (OBJROOT) /DEBUG_X86_64/osfmk/DEBUG/osfmk.filelist: list with component objects osfmk $ (OBJROOT) / DEBUG_X86_64 / mach_kernel: boot image3) make you fat  Determine the architectures in your environment or when running make.  Apply procedure iii, 4, 5  $ make TARGET_CONFIGS = "RELEASE I386 DEFAULT RELEASE X86_64 DEFAULT" exporthdrs all  Where  $ make X86_64 "arch_configs =" i386 exporthdrs all  Where  Export $ X86_64 "arch_configs =" i386  $ make exporthdrs all4) do intense work   To display the tool cues in their entirety instead of the abbreviated version,   $ make VERBOSE = YES5) Debug command formats   By default, the DWARF debug information repository is created during the installation phase. This is a "bundle"    marked mach_kernel.dSYM   Set the BUILD_STABS environment variable to select the legacy STABS debug format (where debug messages are embedded in the mach_kernel.sys image).    export BUILD_STABS = 1  earn $6) Checking the build before integration  In the main directory, do the following:   $ ~ rc / bin / buildit. ! ... ! -arch i386 -arch x86_64 -arch armv7 -arch ppc -noinstallsrc -nosum  xnu keeps multiple XBS build aliases, usually B&I allows build  presenting the actual source multiple times in different sentences in order to  give different results. Each design alias maintains the standard  targets "clean", "install", "installsrc", "installhdrs", however  Conditional its behavior for the variable RC_ProjectName make  where passed to templates as -buildAlias ~ rc / bin / buildit, can be any of the following:  -buildAlias ​​xnu # standard, created / mach_kernel, kernel-space                             Numeric headers, user space headers, man pages,                             Kexts numbers character set  -buildAlias ​​xnu_debug # DEBUG core in / AppleInternal with dSYM  -buildAlias ​​libkxld number User-space kernel linker version  -buildAlias ​​libkmod # static biblibrary is automatically included in kexts  -buildAlias ​​Libsyscall # automatically generate BSD system call stubs  -buildAlias ​​xnu_quick_test # Enable xnu unit tests7) Create beacons and cscope  Set up your build environment as shown in 2a.  In the main directory, do the following:    $ have tags # creates ctags and therefore upper and lower case etags# Volume, ctags case sensitive    $ make TAGS # these are build tags    rr make cscope # this will create the cscope database8) Other Makefile options    make MAKEJOBS = -j8 # this type will use 8 processes when building. By default, twice the number produced by active processors.   $ give about -j8 # widespread, command line option is also accepted   $ make -w # Trace makes recursive calls. Useful in conjunction with VERB = YES   $ BUILD_LTO = 0 make # formula without LLVM connection time optimization   rr make REMOTEBUILD = user @ remotehost # Always run build on remote host================================================B. How to install the updated XNU[To set the IOKit headers, see additional comments in iokit / IOKit / Makefile.]1) XNU stores header files in the following stores -A. $(DSTROOT) /System/Library/Frameworks/Kernel.framework/HeadersB. $ (DSTROOT) /System/Library/Frameworks/Kernel.framework/PrivateHeadersC. $ (DSTROOT) /System/Library/Frameworks/System.framework/HeadersD. $ (DSTROOT) /System/Library/Frameworks/System.framework/PrivateHeadersi.e. $ (DSTROOT) / usr / include /Kernel.framework is created by kernel extensions. System.Frameworkand / usr / include can be used by user-level applications. NameFiles in Framework PrivateHeaders can only be accessed by Apple.Internal development.2) The directory containing the header file must contain a Makefile which contains  creates a list of files to be installed in different locations.   The first time you add a header file that appears in the directory, here's what you need to help you   Create a Makefile similar to xnu / bsd / sys / Makefile.   In fact add the header file to the correct file list depending on where you want  to abort it. Default location and installation location of header files   from any list of files will be -   A. DATA FILES: to access the file header at user levels -$ (DSTROOT) /System/Library/Frameworks/System.framework/Headers$ (DSTROOT) /System/Library/Frameworks/System.framework/PrivateHeaders$ (DSTROOT) / usr / include /   B. PRIVATE_DATAFILES:make the h2 tag file available for internal Apple operations.      User Oriented -$ (DSTROOT) /System/Library/Frameworks/System.framework/PrivateHeaders   C.: Kernel files To make a header file available at the kernel level -$ (DSTROOT) /System/Library/Frameworks/Kernel.framework/Headers$ (DSTROOT) /System/Library/Frameworks/Kernel.framework/PrivateHeaders   D. PRIVATE_KERNELFILES: make the header file available to the internal company      for kernel extensions -$ (DSTROOT) /System/Library/Frameworks/Kernel.framework/PrivateHeaders3) Makefile summarizes cross-file lists various installation entries used by the build system - install the header files.   If the installation list you requested does not exist, create one.  by adding the appropriate file lists. Standard installation lists, its   The member file lists and their crawled locations are described below -   A.

INSTALL_KF_MI_LCL_LIST: Set a header in the file store that      available internally by Apple for kernel extensions.      Resins -$ (DSTROOT) /System/Library/Frameworks/Kernel.framework/PrivateHeaders      Definition -INSTALL_KF_MI_LCL_LIST stands for $ KERNELFILES $ PRIVATE_KERNELFILES4) If you want to install the header file in a subdirectory of this path   described in (1), enter the directory name with two   INSTALL_MI_DIR and EXPORT_MI_DIR always follow -   INSTALL_MI_DIR is equivalent to dirname   EXPORT_MI_DIR = directory name5) A single header file can exist in new interesting places with steps   mentioned above. However, writing all the code might not be desirable.   in the header file if available in all locations. For the fact that you   I only need the latter export function at the kernel level, but not at the user level.   You will most likely be using the language preprocessor directive  ka C (#ifdef, #endif, #ifndef).   to control the overwrite that is created before the header file is created. Core   Strictly include code if macro condition becomes TRUE and removed   Code for FALSE conditions of your current header file.  Some predefined macros and their descriptions are usually -   A.: Private If it comes from the kernel, then the code is undoubtedly available for the whole xnu kernel      Not available in kernel extensions and user-level header files. v      The header files that are installed on the streets described in point (1) above are not actually      included a pin in this macro.   k. KERNEL_PRIVATE: I like PRIVATE   C. BSD_KERNEL_PRIVATE: if true, the code is actually available for all parts of xnu / bsd      usually kernel and not available for other kernels, kernel extensions      and user spot header files. Header files installed with all      The paths described in (1) above should not contain code in this precious      Macro.   D. KERNEL: If so, the code is only available in a kernel with a kernel      Complete and not available in account-level header files. Only that the linking rings of the header installedalong the following paths, have this code -$ (DSTROOT) /System/Library/Frameworks/Kernel.framework/Headers$ (DSTROOT) /System/Library/Frameworks/Kernel.framework/PrivateHeaders
