The released AppImage is a binary package compiled to be used on x86 or x86_64 architectures platforms. As Pi's cpus are using the armv6/armv7 architectures, you need to build from source, by using the tool chain targeting your specific arch (and his assembly code) arm Soc's. Additionnaly, eDEX-UI is maybe using hw graphic accelaration on specific OS (Linux,Windows, MacOS) like opengl that you will not be able to use directly on Pi, because broadcom released only OpenGLES libraries. However, a driver is actually in progress to use the mesa DRI graphic stack and OpenGL targeting the GPU (VideoCore4) on Pi's. As you are running Raspbian Strech, you can enable it.

OK - thanks!

Just leaving a comment that I was able to get this running on a rpi 3 b+ on Raspbian Stretch. But, I had to do a few extra steps:

1. run sudo raspi-config, go to Advanced Options, then GL Driver, choose GL (Fake KMS), and reboot
   (I get a blank screen on boot-up with Full KMS)
2. Fresh clone this repo
3. cd edex-ui && npm install
4. Edit package.json and replace the linux build arch configuration with this:

"linux": {
  "target": [
    {
      "target": "AppImage",
      "arch": [
        "armv7l"
      ]
    }
  ],
  ...
}

5. Because of an issue with electron-builder on Raspian, run git clone https://git.kernel.org/pub/scm/fs/squashfs/squashfs-tools.git
6. sudo apt-get install liblzma5 liblzma-dev
7. cd squashfs-tools/squashfs-tools
8. Uncomment this line in Makefile

XZ_SUPPORT = 1

9. make
10. sudo make install
11. mkdir ~/.cache/electron-builder/appimage/appimage-9.1.0/linux-arm
12. ln -s `which mksquashfs` ~/.cache/electron-builder/appimage/appimage-9.1.0/linux-arm/mksquashfs
13. ln -s `which desktop-file-validate` ~/.cache/electron-builder/appimage/appimage-9.1.0/linux-arm/desktop-file-validate
14. Go back to edex-ui folder cd ../../
15. npm run build-linux

It runs a bit slow, but it is functional and responds to touch events with the official 7" raspberry pi touchscreen.

@thallada Wow. Nice job.

It errored out for me I really want this to run on my raspberry pi 2 as it is the perfect thing for a project I am doing. any advice that might help get this to work?

Maybe post the error? I haven't tried to run on the raspberry pi 2.

Failed at the electron@4.0.5 postinstall script 'node install.js'.

I haven't enabled ARM builds because I don't have any hardware to test them and cannot provide support if something goes wrong. Electron is supposed to have arm support though, so like @thallada said you should be able to get a build running if you really want to.

This is what happens now I have no idea how to decipher this but I feel like I am getting close.

Looks like your version of gcc might be too old for the version of Node that you have. Node 10 needs gcc 4.9+

@C4PT41ND34DP00L

g++: error: unrecognized command line option ‘-std=gnu++1y’

Looks like your version of gcc might be too old for the version of Node that you have. Node 10 needs gcc 4.9+

I updated to gcc 8 and got the same error. I am starting to think I am not the person to figure this out.

@thallada If you have the appimage you got working on the Pi 3 would you mind sharing?
