Hi,

Is it possible for arduino developers using non-lazarus development
tools (maybe android BASIC?) to link their code to a lazarus generated
library?

My library doesn't have any GUI features, just functions for crunching
data.

I've used libraries on other platforms, but don't know enough about
android environment.

Certainly, just use system.loadLibrary on Java, but you need to know
how Java calls native library. On other languages, check out their
respective documentation. Note FPC specific issues as well: name
mangling, calling convention, etc.

Ok sounds good, I guess I should generate a simple echo_string()
function in a library to test with. Do I build a cross compiler for my
existing lazarus system and compile for the android target hardware,
never done that before but will try - or do I need to download lazarus
& android development system (I gave that a go last year and need to
re-install), thanks

Up to you, but I go with the first path. Good for learning and you
know exactly what happens under the hood so you don't just complain if
it doesn't work since you build and configure it yourself.
