I am trying to install the gnu arm toolchain for ubuntu. I first downloaded the tar from CodeSourcery. However when I go into the bin folder, I cannot run any of the binaries. I have tried with ./ and without and putting it in the PATH and it keeps telling me "Command not Found" yet the file is there in the folder right in front of me. Then I tried sudo apt-get install gcc-arm-linux-gnueabi except after it says it has installed successfully, I cannot find it with whereis gcc-arm-linux-gnueabi. Can anyone help?

Are you compiling on a 64-bit OS? Try:
sudo apt-get install ia32-libs
I had the same problem when trying to compile the Raspberry Pi kernel. I was cross-compiling on Ubuntu 12.04 64-bit and the toolchain requires ia32-libs to work on on a 64-bit system.

CodeSourcery convention is to use prefix arm-none-linux-gnueabi- for all executables, not gcc-arm-linux-gnueabi that you mention. So, standard name for CodeSourcery gcc would be arm-none-linux-gnueabi-gcc.
After you have installed CodeSourcery G++, you need to add CodeSourcery directory into your PATH.
Typically, I prefer to install CodeSourcery into directory like /opt/arm-2010q1 or something like that. If you don't know where you have installed it, you can find it using locate arm-none-linux-gnueabi-gcc, however you may need to force to update your locate db using sudo updatedb before locate will work properly.
After you have identified where your CodeSourcery is installed, add it your PATH by editing ~/.bashrc like this:
PATH=/opt/arm-2010q1/bin:$PATH
Also, it is customary and very convenient to define
CROSS_COMPILE=arm-none-linux-gnueabi-
in your .bashrc, because with CROSS_COMPILE defined, most tools will automatically use proper compiler for ARM compilation without you doing anything.

got the same error when trying to cross compile the raspberry pi kernel on ubunto 14.04.03 64bit under VM. the solution was found here:
-Install packages used for cross compiling on the Ubuntu box.
sudo apt-get install gcc-arm-linux-gnueabi make git-core ncurses-dev
-Download the toolchain
cd ~
git clone https://github.com/raspberrypi/tools
-Add the toolchain to your path
PATH=$PATH:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin
notice the x64 version in the path command

If you are on a 64bit build of ubuntu or debian (see e.g. 'cat /proc/version') you should simply use the 64bit cross compilers, if you cloned
git clone https://github.com/raspberrypi/tools
then the 64bit tools are in
tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64
use that directory for the gcc-toolchain. A useful tutorial for compiling that I followed is available here Building and compiling Raspberry PI Kernel (use the -x64 path from above as ${CCPREFIX})

I had to cross compile C code in Ubuntu for ARM. This worked for me:
$ sudo apt install gcc-arm-none-eabi
Later, tested it on the qemu emulator
#Install qemu
sudo apt-get install qemu qemu-user-static qemu-system-arm
#Cross compile "helloworld.c"
$ arm-none-eabi-gcc --specs=rdimon.specs -Wl,--start-group -lgcc -lc -lm -lrdimon -Wl,--end-group helloworld.c -o helloworld
#Run
qemu-arm-static helloworld
sudo find / -name "*gcc-arm*"to find if there are some bin – How Chen
