[Tom Andrews <gta4lj@xxxxxxxxx>]

Hi guys,

Thanks very much for adding this feature for a start, definitely something
I've been wishing for.

Run into an issue off the bat;
Used the script to download/compile the shared lib, and compiled eeschema
with -DKICAD_SPICE=ON, all good.
Loaded up eeschema and opened up sallen_key.sch, opened the simulation
window and set setting to transient with 1n step and 1s finish time,
clicked OK and pressed Run/Stop Simulation, it said no circuits loaded, I
stopped and restart the simulation and the program segfaulted, with this
error in GDB.
(I'm running LMDE 64 bit, kernel 3.16.0-4-amd64)

Let me know how I can be more use/provide more info.
