Here is an excellent doc.
Answer from zhigang on Stack OverflowTool chains have a loose name convention like arch [-vendor] [-os] - eabi
arch - refers to target architecture (which in our case is ARM) vendor - refers to toolchain supplier os - refers to the target operating system eabi - refers to Embedded Application Binary Interfacesome illustrations as follows :
- 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. It is used to target ARM-based Linux systems.

Tool chains have a loose name convention like arch [-vendor] [-os] - eabi
arch - refers to target architecture (which in our case is ARM) vendor - refers to toolchain supplier os - refers to the target operating system eabi - refers to Embedded Application Binary Interfacesome illustrations as follows :
- 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. It is used to target ARM-based Linux systems.
Each architecture or architecture/os couple has an ABI. The ABI (Application binary Interface) describes how functions should be called, syscalls numbers, arguments passed, which registers can be used ...
The abi describes how the compiler should generate the assembly.
If you use only assembler you don't need to care about the ABI.
arm-elf and arm-none-eabi just use two versions of the Arm ABI. The eabi toolchain uses a newer revision, but could also be called arm-elf-eabi, as it generates elf too.
It turned out that ARM decided to make our life easier (sarcasm) by deprecating the use of PPA - their page at launchpad now has an anouncement: "... all new binary and source packages will not be released on Launchpad henceforth ...".
So, to make use of their latest arm-none-eabi-gdb you have to install gcc-arm-embedded manually.
Remove arm-none-eabi-gcc from your system:
sudo apt remove gcc-arm-none-eabi
Download latest version (Linux x86_64 Tarball) from their website, check its MD5. Unpack it into some directory. I used /usr/share/ :
sudo tar xjf gcc-arm-none-eabi-YOUR-VERSION.bz2 -C /usr/share/
Create links so that binaries are accessible system-wide:
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-gcc /usr/bin/arm-none-eabi-gcc
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-g++ /usr/bin/arm-none-eabi-g++
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-gdb /usr/bin/arm-none-eabi-gdb
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-size /usr/bin/arm-none-eabi-size
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-objcopy /usr/bin/arm-none-eabi-objcopy
Install dependencies. ARM's "full installation instructions" listed in readme.txt won't tell you what dependencies are - you have to figure it out by trial and error. In my system I had to manually create symbolic links to force it to work:
sudo apt install libncurses-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/libncurses.so.6 /usr/lib/x86_64-linux-gnu/libncurses.so.5
sudo ln -s /usr/lib/x86_64-linux-gnu/libtinfo.so.6 /usr/lib/x86_64-linux-gnu/libtinfo.so.5
Check if it works:
arm-none-eabi-gcc --version
arm-none-eabi-g++ --version
arm-none-eabi-gdb --version
arm-none-eabi-size --version
I've wrapped the script here by @kmhallen into a semi-automated debian package builder here: https://gitlab.com/alelec/arm-none-eabi-gcc-deb/-/releases
Installing a package like this means you can skip the tedious manual symlinks to put tools on the path, and just as importantly you can uninstall / upgrade to newer packages (assuming I remember to make more packages)
Worked for me on Ubuntu 16.04:
sudo apt install gdb-arm-none-eabi
I had the same issue with Ubuntu 18.04. To install “gcc-arm-none-eabi” on Ubuntu 18.04.
sudo apt-get install gcc-arm-none-eabi
Using this command system install all binary into /usr/bin folder. But Some binaries are not found here. so, I am using its alternative way as below. it's working for me.
If you want to use below arm-none-eabi utility.
arm-none-eabi-gdb
arm-none-eabi-as
arm-none-eabi-objcopy
Download the ARM-GCC toolchain from gnu-mcu-eclipse/arm-none-eabi-gcc
I have downloaded "gnu-mcu-eclipse-arm-none-eabi-gcc-6.3.1-1.1-20180331-0618-centos64" for my x64 System.
After downloaded successfully Extract the compressed file. Go to
/gnu-mcu-eclipse-arm-none-eabi-gcc-6.3.1-1.1-20180331-0618-centos64/gnu-mcu-eclipse/arm-none-eabi-gcc/6.3.1-1.1-20180331-0618/bin
Copy the GDB and objcopy into /usr/bin Directory
sudo cp arm-none-eabi-gdb /usr/bin/
sudo cp arm-none-eabi-objcopy /usr/bin/
After copy you can use the GCC and GDB.
