How do I get arm-elf-as on linux

Question

A make file I'm trying to make has arm-elf-as. I've installed binutils gcc all the stuff I assumed Id need shouldnt arm-elf-as come with that? where can I get this bad boy. I see a lot of questions on here about arm-elf-gcc eabi etc. It has something to do with gnu maybe I should just install a gnu machine on a vm. Ive also googled and came up with gas or I assume gnu as and this webpage https://manned.org/arm-elf-as/f4fae7b2 but no instructions on what arm-elf-as is in. Or how to get it. Its unbuntu, project to be made https://github.com/jeanthom/ibugger

Answer 1

You can simply

sudo apt-get -y install binutils-arm-none-eabi 

and change your makefile from arm-elf-whatever to arm-none-eabi-whatever as the arm-elf builds are a thing of the past generally.

Or you can build from sources, and I just tested this and it is okay with building arm-elf

build_arm-elf:

# Usage
# sudo ./build_arm-elf

# Setup vars
export TARGET=arm-elf
export PREFIX=/opt/gnuarmelf
export PATH=$PATH:$PREFIX/bin
export JN='-j 4'

export BINUVER=2.37

rm -rf build-*
rm -rf binutils-*

# Get archives
wget https://ftp.gnu.org/gnu/binutils/binutils-$BINUVER.tar.gz

# Extract archives
tar xf binutils-$BINUVER.tar.gz

# Build binutils
mkdir build-binutils
cd build-binutils
../binutils-$BINUVER/configure --target=$TARGET --prefix=$PREFIX
echo "MAKEINFO = :" >> Makefile
make $JN all
sudo make install

can change the BINUVER to some older version if so desired.

PATH=/opt/gnuarmelf/bin:$PATH

then you can use arm-elf-as or arm-elf-ld, etc.
