Using Arduino FSM libraries

[gredpath]

We are trying to use the Arduino FSM library from https://github.com/jonblack/arduino-fsm
It builds against the AVR architecture, and the adafruit M0 weatherboard, but it won't compile against Teensy.
Any thoughts?

It comes up with the following messages: -

Apparently, you did not declare the callback functions on_light_on_enter(), on_light_on_exit(), and so on as required by your State declarations. According the tutorial, if callback functions are used as State() constructor parameters, these have to be defined, too. If you don't use callback functions, you can replace these by NULL.

Finally, this does not look a AVR / Teensy problem, but elementary C/C++ knowledge and a little "RTFM until the end..."

But this is only a guess since you did not respect the forum rule and you did not post the code you are actually trying to compile...

in the example light_switch, it references functions before they are defined, try moving

State state_light_on(on_light_on_enter, NULL, &on_light_on_exit);
State state_light_off(on_light_off_enter, NULL, &on_light_off_exit);
Fsm fsm(&state_light_off);

to just in front of setup() function
