Ubuntu 18.04でLinuxカーネルv.5.0.0をクロスコンパイル中にエラーが発生しました。
v7.4.0とv5.5.0の2つの異なるバージョンをテストしましたが、aarch64-linux-gnu-gccどちらも同じエラーが発生しました。
以下は、私がインストールした依存関係とカーネルをコンパイルするために実行したコマンドです。
$ sudo apt install libssl-dev libelf-dev build-essentials libncurses5-dev flex bison gcc-arm-linux-gnueabi gcc-arm-none-eabi gcc-arm-linux-gnueabihf gcc-arm-none-eabi-source
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j
私が受け取ったエラーメッセージは次のとおりです。
