Stop typing make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=… when building the Linux kernel

This post shows you stop typing make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=… -j2 and just type make when building the Linux kernel.

Versions Used

linux-4.10.6 from https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.10.6.tar.xz

GNU Make 4.1 Built for x86_64-pc-linux-gnu (type make –version to list this)

Steps

Instead of typing:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=$TOP/obj/linux-arm-versatile_defconfig -j2

You can set ARCH, CROSS_COMPILE, the output directory (O) and the number of make jobs (-j2) using environment variables (bash):

Type the following in your terminal:

export ARCH=arm

export CROSS_COMPILE=arm-linux-gnueabi-

export KBUILD_OUTPUT=$TOP/obj/linux-arm-versatile_defconfig

export MAKEFLAGS=j2

Then you can just type make
