Is this correct? Or do I need to build KiCad with a special option?
Look at how the test program is built down in /tools. I wrote a document
model parsing function that gives you a boost propert tree as a document.
A second path is to try and lind to libcommon, but this will flop due to
unredolved ecternals if you stray too far from richio and dsnlexer.
A final and third option is to link with _pcbnew.so which basically all of
pcbnew in DSO form. Currently this is only built is SCRIPTING is bulit,
but I will be changing this in the next handful of weeks so it always gets
Are you using wx as your ui?
