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.

The GNU Arm Embedded Toolchain is a ready-to-use, open-source suite of tools for C, C++ and assembly programming. The GNU Arm Embedded Toolchain targets the 32-bit Arm Cortex-A, Arm Cortex-M, and Arm Cortex-R processor families.
A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a PC but generates code that runs on an Android smartphone is a cross compiler.
arm-none-eabi - This tool chain targets for ARM architecture, has no vendor, does not target an operating system and complies with the ARM EABI. arm-none-linux-gnueabi - This toolchain targets the ARM architecture, has no vendor, creates binaries that run on the Linux operating system, and uses the GNU EABI.
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.

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).
untar it
tar xvf arm-2013.05-24-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
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"
