I'd expect that it wouldn't be *too* much bother. There's a lot of
shared code with libmosquitto and it runs fine on iOS. I'd probably
check the config.mk file and disable all of the optional bits to start
with.

Sounds reasonable. You'd probably want to rename main() to something
else of course.

I've considered making a "mosquitto embedded" before - when someone
was talking about running an MQTT broker on a microcontroller or very
constrained embedded computer. If you're willing to spend some time
fiddling with the code you can make the executable quite small, which
might fit your purpose. Things like the config file parsing take up a
lot of space and probably wouldn't be directly applicable for example.
I managed to get down to a stripped executable size of 31kB.

Cheers,

Roger
