This guide should help you with cross-compiling other software as well (at least give you some pointers if you’re new to this).
So, I got a Synology NAS. It’s a Linux box running on x86_64 (AKA AMD64), but it has no nano. My laptop is a Mac, running on aarch64 (AKA ARM64).
So, I decided to fire up an Ubuntu (20.04) VM on my laptop, and statically cross-compile nano, to get a single binary I could just drop into my NAS.
Installing the compiler and libraries
sudo apt install build-essential gcc-x86-64-linux-gnu libncurses-dev
However, to statically compile this, we also need the x86_64 version of the library installed (which will then be “packed” into the final binary, that’s how static compiling works).
Create the file
/etc/apt/sources.list.d/amd64.list with the following content:
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
Make sure to replace “focal” with whatever distro you are using. These are the Ubuntu repos for amd64 (x86_64), which we need to obtain the amd64 version of packages.
Now update the package list and add the architecture:
sudo apt update sudo dpkg --add-architecture amd64 sudo apt update
Now install the x86_64 version of libncurses-dev:
sudo apt install libncurses-dev:amd64
That should be all, let’s continue!
Getting the source and building
wget https://www.nano-editor.org/dist/v6/nano-6.2.tar.xz tar xf nano-6.2.tar.xz cd nano-6.2/ CC=x86_64-linux-gnu-gcc ./configure --host x86_64 CFLAGS="-O2 -Wall --static" make
Now when we run
find . -name nano we will find exactly one binary built at
Let’s verify that it built as x86_64, and that it’s statically linked:
src/nano: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, BuildID[sha1]=838510eaef96345242a4e9adcc29001a8722f1af, for GNU/Linux 3.2.0, not stripped
We can see “x86-64” and “statically linked”. Sounds good! Deploy it on your x86_64 NAS on /usr/local/bin to install nano system-wide. You can do that with SCP. Make sure to test it, though.
I find it amusing, BTW. Usually one is on x86_64, cross-compiling for an embedded device running aarch64… But this time, it’s the other way around. (:
Either way, no more VIM! :D
