How do I install x86_64-elf-ld on ubuntu 20.04?

I am trying to write an OS kernel and I need a certain dependency for compiling the assembly to an iso binary. The dependency is x86_64-elf-ld. I cannot find any resources for installing it on ubuntu online so I thought I would ask the internet.

Solution

If really needed, you can build x86_64-elf-ld from latest binutils source code with the following commands:

wget https://ftp.gnu.org/gnu/binutils/binutils-2.36.1.tar.xz
tar Jxf binutils-2.36.1.tar.xz
mkdir binutils
pushd binutils
 ../binutils-2.36.1/configure --prefix=/usr/local --target=x86_64-elf --program-prefix=x86_64-elf- 
make all
sudo make install
popd

ls -ail /usr/local/bin/x86_64-elf-*

Please note that you may have to install one or more of the following packages on Ubuntu or Debian first: build-essential, flex, bison, libisl-dev, texinfo texlive.
