Why don't you simply follow what I DID? First of deinstall that apt fpc
again. Then download 3.2.2 for aarch64-linux from SourceForge, install it
and add /path/to/where/you/installed/fpc/bin to your PATH (using "export
PATH=/new/path:$PATH").
Best pick in an installation path like /wherever/fpc/<version> and select
"yes" when asked whether to adjust the fpc.cfg with $fpcversion, that will
come in handy later.

Next download the sources for 3.2.3 and extract them somewhere different
than "/wherever/fpc". Change into that directory and execute the commands
as I had written in my previous mail (you should be in the same command
line session where you adjusted PATH for this to work otherwise you need to
set it again). The INSTALL_PREFIX should be "/wherever/fpc/3.2.3".

Next set your PATH again, but this time use the directory for 3.2.3 ("echo
$PATH" plus selecting and pasting is your friend here, cause you don't want
to *extend* your path, but replace it; or simply start a new console
windows and append the path there now that I think about it 😅).

Now you should have a working FPC and you can compile Lazarus from source
(sorry, don't know how to setup fpcupdeluxe to use an existing compiler,
cause I don't use it).

In Lazarus you then also need to set the path to your compiler.

Regards,
Sven
