serialport: wrong ELF class: ELFCLASS64

muccix commented 6 years ago

Version: 20.0.4
Target: target=AppImage arch=armv7l
npm version: 5.6.0

NB: Not sure this is an electron-builder issue.

I'm building an app from a linux mint sytem (64bit). When I try to run the application on the target machine (raspberry PI 3) I get the follofing error:

Uncaught Exception:
Error: /tmp/.org.chromium.Chromium.Nz7oiq: wrong ELF class: ELFCLASS64

To me, It looks like the package serialport is compile for a 64bit system instead of 32bit.

Her is my package.json:

electron-rebuild is not required — electron-builder rebuilds deps.
Probably serialport doesn't provide prebuild version for "raspberry PI 3" — arm64 (check what arch). Please file issue to serialport As far I see — https://github.com/node-serialport/node-serialport/releases/tag/v6.1.0 — no prebuilds for ARM.

@muccix Did you have any luck with resolving this? I'm having the same issue.

I have not solution but workaround that works for me (after several hours of experiments without solution)

Take correctly builded node_modules/@serialport on Raspberry and copy them on system where you are building AppImage. (npm install have to be called before copying) In your package.json add

"build":
...
    "npmRebuild":false
...

Than call npm build

After running AppImage on RPi you may have this issue https://github.com/RocketChat/Rocket.Chat.Electron/issues/676 with noexec on /tmp

I have the same issue as well, any solution? @Macek007 I am building an electron app on an ubuntu machine with different architecture creating an appImage for raspberry. everything works until I use the serial port. could you please explain more about the solution?
