| Pre-compiled modules |
| ==================== |
| |
| Some modules are pre-compiled due to needing cross-compilers present on the |
| build/dev machine which is inconvenient. 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. |
