Arch Linux User Repository

@gyurman: hi,
I know nothing about cross compiling, sorry.

If I were you, first I would give a try to scratch3-bin. See my post.

If it doesn't run, I would then try to make a direct compile so as to check
if the resulting package is usable, even if it takes 2 hours to compile.
If not, don't waste your time in trying to cross compile! It won't run any better...

If the resulting package is usable, only then I would try cross compiling (If I were you).

Don't forget to report, thanks!

How can I build with x64 system volunteer for aarch64? Same as distccd? https://wiki.archlinux.org/title/Distcc#Cross_compiling_with_distcc

@Gyurman: szia,
I think I found a way to successfully build the package on your device.
In fact you were almost done!

The output directory used by electron-builder is
dist/linux-arm64-unpacked because of your ARM system
instead of dist/linux-unpacked (for arch=x86_64).
Something I couldn't be aware of.

I updated the PKGBUILD: it reads now the system's architecture value
and should use the right folder accordingly. But it needs testing
since I don't have such a device.

After 2 hours build:

 -> error making: scratch3

From version 3.27.0-3 and later

Instead of using the windows binary, this version will build the app from sources, targeting Electron version 13.6.y.
If you prefer the other way, then install scratch3-bin instead.

Before starting the installation, please check your disk space, the PKGBUILD won't do it for you.

Total size of the build directory on my system: 1.9 GiB (2 009 713 885)

Tested successfully under KDE/Plasma X11 arch=x86_64.

Any feedback are welcomed.

Hi, I digged a bit deeper as why we can only use electron11 and only, if you copy the complete electron11 into the scratch-installation.

• found this: https://gist.github.com/lyshie/0c49393076b8b375ca1bd98c28f95fb0#gistcomment-3808921 and found that I can let scratch run with electron11, electron13, electron14 and electron (16) using the trick to "disable" contextIsolation

• however, the images are missing / not loading if the systemwide electron is used and only shown if electron is copied to scratch-installation. I did not find a way to circumvent this.

• the other deprecation issues should be looked upon closely: "DeprecationWarning: Buffer()" from electron11 upwards, e.g.

• there is another problem: electron14 and upwards do not show the "save to computer" dialog, but GTK shows an error message:

 Gtk: gtk_native_dialog_run: assertion '!priv->visible' failed

To sum up:

• electron13 is the maximum that seems to work for now and only when copied to the scratch-installation
• the electron13 (or whichever) does not need to be installed systemwide just for the packaging. Especially when you use a not maintained version (11).

@etaboon I just made it, thank you
