Windows error at runtime : "No native build was found"

[taratatach]

• Version: 21.2.0

• Target: nsis:ia32

I'm packaging a Windows 32bit (as well as x64) application from an x64 AppVeyor VM with Node x64.
My app has a dependency on leveldown v5.0.2 which does not provide 32bit prebuilt binaries anymore.

As can be seen in the following logs, electron-rebuild seems to succeed at compiling it itself:

However, when the app is launched on a x86 Windows, it fails with the following error:

Error: No native build was found for runtime=electron abi=70 platform=win32glibc arch=ia32

This seems to happen when we load leveldown.

I couldn't find any solution to this problem and figured this could be a configuration problem when running electron-builder for another architecture.

Looks similar to #4389

[Mhmetengineer]

Can u solve this problem ? @taratatach

[taratatach]

I haven't found the time to work on this so no solution yet.
I was hoping the electron-builder team would have an idea on where this could come from.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.

I missed the bot notification. Can we reopen this?

Coming across this issue now in our app, seems to be related to leveldown not having a prebuild for 32bit windows. Asking @vweevers & leveldown team to include a prebuilt, although still waiting to hear if that will happen

[vweevers]

Released leveldown 5.6.0 with a 32-bit Windows prebuild.
