Beagleboard用のCross Linux From Scratch（CLFS）用のGCCクロスコンパイラーを構築する方法

10

現在、私はからの命令でゼロから組込みLinuxを構築しようとスクラッチからのクロスのLinux。

GCCクロスコンパイラーをコンパイルしようとするまで、すべてがうまくいきました。Beagleboard-xM用のLinuxを構築したいので、次の設定を選択しました。

export CLFS_ABI="aapcs-linux"
export CLFS_HOST="x86_64-cross-linux-gnu"
export CLFS_TARGET="armv7a-unknown-linux-uclibceabi"
export CLFS_ARCH="arm"
export CLFS_ENDIAN="little"
export CLFS_ARM_ARCH="armv7"
export CLFS_ARM_MODE="arm"
export CLFS_FLOAT="hard"
export CLFS_FPU="neon"

いいえ、このページの手順を実行しようとすると、コマンドでmake all-gcc all-target-libgccエラーが発生します。

CLFSの代わりにBuildrootを使用することを検討してください。ソースから完全に自動化されており、非常に広く使用されており、信頼性があります。または、Buildrootが何をしているかを調べて、それをコピーします。

エラーは、ビルド変数の誤った組み合わせが原因である可能性があります。

CLFSは、変数のビルドページは、異なるアーキテクチャの変数設定の最良の組み合わせに詳しい説明があります。

同様の構成スクリプトの問題は、CLFS_ARCH変数を次のように変更することで解決されましたthumb

別の同様の BeagleBoard構成スクリプトエラーの場合、次の一連の変数がうまくいくようです。ARMv7-A Thumb-2 - Little-Endian, Soft-Float, GLIBC

CLFS 1.xxを使用している場合は、CLFS 2.xxを使用して、更新されたドキュメントとともに、よりクリーンなビルド方法を検討してください。

CLFSの問題について話し合うのに最適な場所はclfs-supportメーリングリストにあります。詳細については、そこで質問してみてください。
