Advice regarding installing ARM toolchain on Ubuntu VM (64bit)

Question

Trying to compile Linux kernel for arm platform on a Ubuntu virtual machine

$make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

It fails as follows

arm-none-linux-gnueabi-gcc: not found

Tried to install

$sudo apt-get install arm-none-linux-gnueabi-gcc

E: unable to locate package arm-none-linux-gnueabi-gcc

Where to find the correct package? how to include it in the system? (I found a couple of links on line that didn't work for me). It would be great if you could provide a correct solution or reference.

Answer 1

1. Download arm-2013.05-24-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 from https://sourcery.mentor.com/GNUToolchain/

   or https://sourcery.mentor.com/sgpp/lite/arm/portal/subscription?@template=lite

   Get correct version of the arm-none-linux-gnueabi toolchain (i.e. targetting GNU/Linux rather than EABI).

2. untar it

   tar xvf arm-2013.05-24-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
   

3. open bashrc

   vi .bashrc
   

   at the end add below comand

   export PATH=$PATH:{path to toolchain}arm-2013.05/bin
   

   e.g export PATH=$PATH:/home/vinay/under_linux/arm-2013.05/bin

   save it and quit the terminal.

then you can cross-compile without everytime export.

Also take of correct toolchain there are two toolchain available choose according to your requirement.

Cross compile error "arm-none-eabi-g++ cannot find entry symbol"

Answer 2

The Ubuntu package names are gcc-arm-linux-gnueabi/gcc-arm-linux-gnueabihf.

For building the kernel, which one you use does not make much difference. For building anything else, "gnueabihf" is the hard-float version. For any modern ARM processor (this statement excludes the Raspberry PI), this is the one you would want.
