i have next error build output when using library have linked through monotouch linking project.

undefined symbols architecture armv7:

i have tried adding audiounit in linkwith file , framework not found error. have tried adding coreaudio same effect.

sorry code dump. hope can help me out there, stuck in hole @ moment.

as missing references new() tend indicate, you're binding c++ library (or wrapper c++ lib).

it library depend on (c++) other one, add together [linkwith] attribute 1

and maintain in mind c++ library should have property iscxx=true set in linkwith attribute

[assembly: linkwith ("libmtscra.a", iscxx=true, linktarget = linktarget.armv7 | linktarget.armv6 | linktarget.simulator, frameworks = "audiotoolbox externalaccessory foundation", forceload = true)]
