1 Pre-compiled modules 2 ==================== 3 4 Some modules are pre-compiled due to needing cross-compilers present on the 5 build/dev machine which is inconvenient. Makefile is ready to compile them again 6 in case they are missing: 7 8 1) Prepare the linux kernel trees to build external modules, i.e.: 9 10 kernel $ make ARCH=<arch> CROSS_COMPILER=<cross-compiler-prefix> defconfig 11 kernel $ make ARCH=<arch> CROSS_COMPILER=<cross-compiler-prefix> modules_prepare 12 13 For each architecture. See the Makefile to check which are the supported architectures. 14 15 2) Export the variables below to point to the right place: 16 17 KDIR_<arch>: for each architecture it needs to point to a 18 kernel tree configured as in (1) 19 20 CROSS_COMPILER_<arch: for each architecture it needs to point to the 21 correct toolchain prefix. Leave it blank if a 22 cross-compiler is not needed (example: you are 23 building a 32b module with a multilib compiler). 24 25 26 3) Remove every %-<arch>.ko. After this the build system will recreate them. 27
