32 bit software running under 64 bit OS

[Andreas Reschke]

Hi there,

i want to try install 32 Bit software ( Moneyplex = Homebanking 
software) on my Fedora aarch64 system. This didn't work.

[andreas@pinebook-pro moneyplex]$ ll
total 22468
-rwxr--r--. 1 andreas andreas  7543589 Jan 21  2020 Handbuch.pdf
-rwxr-xr-x. 1 andreas andreas 12369492 Apr 29  2020 moneyplex

[andreas@pinebook-pro moneyplex]$

Is this supportet? If yes, how can I solve this?

Thanks

We don't support 32/64 bit multi lib on aarch64, it's a complex
problem and not all aarch64 devices support running native 32 bit
code, the way you could solve this is to run the software in a
container/flatpak. I don't know enough about that software, whether it
has a GUI of some sort etc, to specify what would be the best option
there.
