1 How to build XNU: 2 3 1) Type: "make" 4 5 This builds all the components for all architectures defined in 6 ARCH_CONFIGS and for all kernel configurations defined in KERNEL_CONFIGS. 7 By default, ARCH_CONFIGS contains one architecture, the build machine 8 architecture, and KERNEL_CONFIGS is set to build for RELEASE. 9 This will also create a bootable image, mach_kernel, and a kernel binary 10 with symbols, mach_kernel.sys. 11 12 Example: 13 $(OBJROOT)/RELEASE_PPC/osfmk/RELEASE/osfmk.o: pre-linked object for osfmk component 14 $(OBJROOT)/RELEASE_PPC/mach_kernel: bootable image 15 16 2) Building a Component 17 18 Go to the top directory in your XNU project. 19 20 If you are using a sh-style shell, run the following command: 21 $ . SETUP/setup.sh 22 23 If you are using a csh-style shell, run the following command: 24 % source SETUP/setup.csh 25 26 This will define the following environmental variables: 27 SRCROOT, OBJROOT, DSTROOT, SYMROOT 28 29 From a component top directory: 30 31 $ make all 32 33 This builds a component for all architectures defined in ARCH_CONFIGS 34 and for all kernel configurations defined in KERNEL_CONFIGS. 35 By default, ARCH_CONFIGS contains one architecture, the build machine 36 architecture, and KERNEL_CONFIGS is set to build for RELEASE . 37 38 Example: 39 $(OBJROOT)/RELEASE_PPC/osfmk/RELEASE/osfmk.o: pre-linked object for osfmk component 40 41 From the component top directory: 42 43 $ make mach_kernel 44 45 This includes your component in the bootable image, mach_kernel, and 46 in the kernel binary with symbols, mach_kernel.sys. 47 48 WARNING: If a component header file has been modified, you will have to do 49 the above procedure 1. 50 51 3) Building DEBUG 52 53 Define KERNEL_CONFIGS to DEBUG in your environment or when running a 54 make command. Then, apply procedures 4, 5 55 56 $ make KERNEL_CONFIGS=DEBUG all 57 58 or 59 60 $ export KERNEL_CONFIGS=DEBUG 61 $ make all 62 63 Example: 64 $(OBJROOT)/DEBUG_PPC/osfmk/DEBUG/osfmk.o: pre-linked object for osfmk component 65 $(OBJROOT)/DEBUG_PPC/mach_kernel: bootable image 66 67 4) Building fat 68 69 Define ARCH_CONFIGS in your environment or when running a make command. 70 Apply procedures 3, 4, 5 71 72 $ make ARCH_CONFIGS="PPC I386" exporthdrs all 73 74 or 75 76 $ export ARCH_CONFIGS="PPC I386" 77 $ make exporthdrs all 78 79 5) Build check before integration 80 81 From the top directory, run: 82 83 $ ~rc/bin/buildit . -arch ppc -arch i386 -noinstallsrc -nosum 84 85 6) Creating tags and cscope 86 87 Set up your build environment as per instructions in 2a 88 89 From the top directory, run: 90 91 $ make tags # this will build ctags and etags 92 93 $ make cscope # this will build cscope database 94
