I'm trying to run ElectronJS app to Buildroot-based Operating System for a vehicle instrument. The SBC is Raspberry Pi 4B and target packages are included based on Debian's dependencies list. Then after I run the app, it throws this message:

# DISPLAY=:0 ./my-app --no-sandbox --disable-gpu-sandbox
./my-app: /usr/lib64/libasound.so.2: no version information available (required by ./my-app)

Keep in mind that glxgears and glxinfo are working perfectly. The frame rate is around 198 FPS. Thus, GPU supposed to not be blamed.

I am pretty sure something wrong with ALSA libraries or DBUS, perhaps anyone experiencing same problem? Thanks!

    I believe I am seeing similar. I hadn't seen your post, so posted a question [here](https://raspberrypi.stackexchange.com/questions/136506/pi4-electron-gui-using-buildroot). I do not have a solution to offer unfortunately – bjornruffians Mar 08 '22 at 20:16

Adding { frame: false, fullscreen: true } in the electron BrowserWindow constructor options make it work.

  • Turns out that I already [added it to the source code](https://github.com/ventros-project/core-electron/blob/5fed234fa4b1420652ac30cf5f61be3a90055a09/main.js#L32) and still has the issue – Thor-x86_128 Apr 25 '22 at 17:46

    For the d-bus error logs, using `DISPLAY=:0 dbus-launch ./my-app --no-sandbox --disable-gpu-sandbox` should fix dbus error logs. Do you have enabled "alsa-lib" in Target packages → Libraries → Audio/Sound build root config ? – angelodlfrtr Apr 26 '22 at 09:59
  • Sorry for late response, @angelodlfrtr It's already installed but it's using Wayland instead of Xorg-server (EDIT: revert to Xorg-server and still same, perhaps buildroot bug?) – Thor-x86_128 May 24 '22 at 18:06
