How to make a 32bit arm app run on 64bit arm OS

Targets Raspberry Pi

Hello all,

Can anyone help me run a 32bit ARM Xojo App run on a 64bit Raspberry Pi OS?

Thanks,
Tim

Well, it is easier to match the architecture and build your app as arm64. If you deliver a package, you could have a shell script to lookup which one to install or deliver the app as multi-architecture deb.

To run 32-bit on 64-bit ARM machines, you could install an additional architecture for the package manager, e.g.

dpkg --add-architecture armhf

and then you would install packages needed with the architecture postfix, e.g.

apt-get update
apt-get install libc6:armhf libstdc++6:armhf

Thanks Christian.
I plan to update all of the apps that are used to 64bit. However the web app that runs is based on 2019R1.1 and the replacement is not nearly ready yet. If not for that app, it would all be 64bit.
