buildrootでzimageを作成する(アドエス用)

○buildrootでzimageを作成する
→カーネルを取得
$ wget http://www.kernel.org/pub//linux/kernel/v2.6//linux-2.6.34.1tar.bz2
$ tar xvf linux-2.6.34.1.tar.bz2
$ cd linux-2.6.34.1/

→.configをコピー。(アドエス用)

$ cd ~/buildroot/buildroot/output/staging/usr/bin
$ ln -s ~/work/cross_kernel/linux-2.6.34.1/ linux
$ cd linux

※以下、ルート権限で実行する。
($ sudo su)

export PATH=$PATH:/home/jpdadmin/buildroot/buildroot/output/staging/usr/bin

- - - - -

$ make ARCH=arm CROSS_COMPILE=arm-linux- mrproper
$ make ARCH=arm CROSS_COMPILE=arm-linux- allnoconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig

- - - - -

※今回は実績のある.configを使用するので以下を実行
$ make ARCH=arm CROSS_COMPILE=arm-linux- oldconfig

→ビルド開始
$ make -j2 ARCH=arm CROSS_COMPILE=arm-linux-

■エラー発生で終了

__LINUX_ARM_ARCH__がないって言われるよ〜

→パッチの当て忘れが判明
　あわてるな。
