[zeromq-dev] embedding zeromq question

[Thomas Taranowski]

You could try building with -ffunction-sections argument.  This places
each function in it's own section, which results in the linker
stripping out any unused functions.  I've had fairly good success with
code size reduction on embedded C projects, but have not tried it on
zmq.

I've built several messaging type IPC's and have no desire to generalize them to multiple processes.  It will come down to code size.  Maybe we can do as others did and statically link but I would rather be able to trim out functionality via a smart linker, or if needed, by hand.  It would depend on how modular the internals of libzmq are.
