Failed to load Pepper Flash plugin in an Electron app bundled in an AppImage

• Version: latest

• Target: Linux (AppImage)

Please consider the following sample project: https://github.com/hokein/electron-sample-apps/tree/master/pepper-flash-plugin

I’ve cloned it, copied Flash plugin to app folder, completed the remaining steps to be able to build it with electron-builder and built it with AppImage target.

However, when I try to run the AppImage, it doesn’t load the plugin. Instead, it renders a message like “Unable to load the plugin”

Here is the output of my ldd libpepflashplayer.so command:

        linux-vdso.so.1 (0x00007ffe073bb000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007fb3837f1000)

        /lib64/ld-linux-x86-64.so.2 (0x00005640c7d3a000)

Should I include any of these libs as a dependency in my build process?

I’ve got it! The correct path (for Linux) is ${__dirname}/../../, if installed via extraFiles, or ${__dirname}/../../resources, if installed via extraResources one.

I would like to suggest you to include these details in electron-builder documentation.

It’s not working for me. I have a folder named flash that has my plugins.

"extraResources": "${__dirname}/flash/*",

It doesn’t copy the files. Anyone know why?

Update: I didn’t realize extraResources was for the build section of package.json.
