| How to build the ARC linux kernel to a known working configuration. |
| |
| 1. Provide kernel build system with a suitable config file. |
| make ARCH=arc defconfig # selects arch/arc/configs/aa4_defconfig |
| |
| 2. To tweak the .config |
| make ARCH=arc menuconfig # there's a new cool looking nconfig target as well |
| |
| 3. Build it (no need to use the bootpImage target now) |
| make ARCH=arc |
| |
| Notes: |
| |
| 1. ARCH=arc for each cmd can be an inconvenince. You can either add it to |
| your top level Makefile (locally) or define an env var or define a shell |
| alias mymake='make ARCH=arc' etc |
| |
| 2. kernel headers are needed for building the uClibc based ARC GNU |
| tool-chain. However passing it a virgin checked-out kernel tree will trip |
| the tool-chain build, as some of the uClibc sources #include generated |
| kernel headers such as version.h and autoconf.h |
| So do an intial kernel build - even if it fails because there is no |
| elf32 tool-chain yet as it's sufficient to generate the needed hdrs. |
