👋 Hello! This repository contains several patched files and instructions that allow you to build and run Atom 1.23 on armv7l machines like Raspberry Pi's.

Firstly, clone Atom sources from 1.23-releases branch and this repository, then merge them:

git clone https://github.com/atom/atom.git -b 1.23-releases
git clone https://github.com/hypersad/atom-armv7l.git
cp -r atom-armv7l/script/* atom/script/
rm -rf atom-armv7l

Now you could start building:

cd atom
script/build

Building Atom on armv7l machines usually takes around 1-2 hours, but build time depends on your hardware.

This steps must be done on i386/amd64 machine.

We will use mksnapshot binaries for i386/amd64 with armv7l as target to get startup blob. I've tried to build mksnapshot binaries for armv7l that works natively, but Atom just throws Illegal instruction error with their blobs. Currently, I don't know how to skip this step and make snapshot natively. You could try to use i386 emulator for this, if you want of coure.

Get suitable mksnapshot binary. For now it is mksnapshot-v1.6.0-linux-armv7l:

wget https://github.com/electron/electron/releases/download/v1.6.0/mksnapshot-v1.6.0-linux-armv7l.zip
unzip -j mksnapshot-v1.6.0-linux-armv7l.zip mksnapshot
rm mksnapshot-v1.6.0-linux-armv7l.zip

Get generated startup snapshot (out/startup.js) from your armv7l machine. You could do it via scp, for example:

scp [email protected]:/home/helix/atom/out/startup.js startup.js

Generate startup blob from startup.js via mksnapshot:

./mksnapshot startup.js --startup_blob snapshot_blob.bin

Send generated startup blob back to your armv7l machine. You could do it via scp too, for example:

scp snapshot_blob.bin [email protected]:/home/helix/atom/out/atom-1.23.2-armv7l/snapshot_blob.bin

Now, you could try to launch Atom! 🎉
