So, I wanted to learn how to create an electron application as Flatpak. Mainly because I wanted to create a Flatpak version of some of my favourite applications and possibly publish them on Flathub. I followed the instructions here LINK and tried to create Flatpak for electron-sample-app. Unfortunately, after 2 days of trying different solutions, reading docs, searching GitHub and GitLab I am lost.
I’m running Fedora 33.
What I did:
flatpak-builder build org.flathub.electron-sample-app.yml --install
Immediately after starting the build process, an error appears, but the process continues:
flatpak-builder:802504): Json-WARNING **: 12:38:01.204: Failed to deserialize "sources" property of type "gpointer" for an object of type "BuilderModule"
and at the end of NodeJS build process,
flatpak-builder cannot install dependencies from generated-sources.json file.
To fix this, I run
npm audit fix, generated a new
generated-sources.json file and started the build process again. This time there were no errors, except:
error: Flatpak system operation ConfigureRemote not allowed for user
Install failed: Child process exited with code 1
So, I’ve installed once again, this time with
--user option. Success.
The problem is, when I run flatpak, the main window appears, but without any content (only black screen). The Flatpak throws an error:
Gtk-Message: Failed to load module "canberra-gtk-module" Gtk-Message: Failed to load module "pk-gtk-module" Gtk-Message: Failed to load module "canberra-gtk-module" Gtk-Message: Failed to load module "pk-gtk-module"
The same thing happens when I’m using ‘Electron 2.0.18’ and
I was trying to use different runetimes and sdk’s(freedesktop 20.08) but due to lack of Python 2.7 support I was unable to build NodeJS below version 13. The build process of NodeJS 14 crashes here:
/run/build/nodejs/out/Release/obj.target/tools/v8_gypfiles/libv8_initializers.a -lm -ldl -Wl,--end-group collect2: fatal error: ld terminated with signal 15 [Terminated] compilation terminated. make: *** [cctest.target.mk:230: /run/build/nodejs/out/Release/cctest] Error 1 make: *** Waiting for unfinished jobs.....
Is there any proper solution for building Flatpak electron app?
