build kernel with aarch64-linux-gnu-gcc

Question

I am trying to build the kernel source on my platform with the following command:

make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- generic-v8-defconfig

However, the error messages appear as shown in the following:

/bin/sh: 1: aarch64-linux-gnu-gcc: not found

It's obvious I have not this version of gcc installed on my laptop.

I then followed

http://www.howtoinstall.co/en/ubuntu/trusty/main/gcc-4.8-aarch64-linux-gnu/

This to install gcc-4.8-aarch-linux-gnu,

however, I still get the same error message.

Ubuntu version: 14.04

Please let me know if you know how to fix this.

Thanks

Answer 1

Maybe aarch64-linux-gnu-gcc is not installed. Try

sudo apt-get install gcc-aarch64-linux-gnu

Answer 2

looks like a PATH issue. what happens when you just type "aarch64-linux-gnu-gcc "in your shell? does it find the compiler?

Answer 3

You can use the following commands:

sudo add-apt-repository ppa:linaro-maintainers/toolchain
sudo apt-get update
sudo apt-get install gcc-**version**-aarch64-linux-gnu

Make sure to replace **version** by the correct version.

Answer 4

Try it:

debian/ubuntu:

sudo apt-get install gcc-aarch64-linux-gnu # GNU C compiler for the arm64 architecture
sudo apt-get install g++-aarch64-linux-gnu # GNU C++ compiler

Answer 5

Use ndk tool to install the arm64 cross compiler:

$NDK_ROOT/build/tools/make-standalone-toolchain.sh --arch=arm64 --install-dir=/opt/android-toolchain export PATH=$PATH:/opt/android-toolchain

Answer 6

Do this, it will get solved CROSS_COMPILE=aarch64-linux-gnu- make flash.bin -j $(nproc --all)
