linux内核--试图在ubuntu上交叉编译(用于rpi 0)

Question

我只是尝试在linux内核git存储库上运行make bcmrpi_defconfig。

RT的patched：

wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/4.19/patch-4.19.127-rt55.patch.gz
zcat patch-4.19.127-rt55.patch.gz | patch -p1

但是它说<#>cannot找到arm编译器.

phil@rt-linux-pi:~/linux$ /home/phil/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc
bash: /home/phil/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian
/bin/arm-linux-gnueabihf-gcc: No such file or directory

phil@rt-linux-pi:~/linux$ ls /home/phil/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc -lha
lrwxrwxrwx 1 phil phil 29 Jun 25 22:58 /home/phil/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc -> arm-linux-gnueabihf-gcc-4.8.3

I现在实现了arm-linux-gnueabihf-gcc在系统上找不到的

I得到这个错误：

I尝试了：

• 安装构建要点
• 我安装了以下软件包: libncurses-dev flex bison openssl libssl-dev libelf-dev libudev-dev libpci-dev libiberty-dev autoconf。
• 我修改了路径变量：

echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/phil/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/

谢谢你花在这个问题上的时间

问候

我遵循本教程：http://www.frank-durr.de/?p=203

官方医生用一种更“新”的方式更好地解释了事情。

https://www.raspberrypi.org/documentation/linux/kernel/building.md

第一个mod和源程序.bashrc文件，并在末尾添加：

if [ -d "$HOME/tools/arm-bcm2708/arm-linux-gnueabihf/bin" ] ; then
    PATH="$PATH:$HOME/tools/arm-bcm2708/arm-linux-gnueabihf/bin"
fi

要构建内核，请执行以下操作：

sudo apt install git bc bison flex libssl-dev make libc6-dev libncurses5-dev

git clone --depth=1 --branch rpi-4.19.y https://github.com/raspberrypi/linux

cd linux
export KERNEL=kernel
make bcmrpi_defconfig

cd ..
git clone https://github.com/raspberrypi/tools ~/tools

cd linux

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcmrpi_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs

希望这对其他人也有帮助
