Makefile is ready to compile them again +in case they are missing: + +1) Prepare the linux kernel trees to build external modules, i.e.: + + kernel $ make ARCH=<arch> CROSS_COMPILER=<cross-compiler-prefix> defconfig + kernel $ make ARCH=<arch> CROSS_COMPILER=<cross-compiler-prefix> modules_prepare + + For each architecture. See the Makefile to check which are the supported architectures. + +2) Export the variables below to point to the right place: + + KDIR_<arch>: for each architecture it needs to point to a + kernel tree configured as in (1) + + CROSS_COMPILER_<arch: for each architecture it needs to point to the + correct toolchain prefix. Leave it blank if a + cross-compiler is not needed (example: you are + building a 32b module with a multilib compiler). + + +3) Remove every %-<arch>.ko. After this the build system will recreate them. |
