Hi there,

Whenever I add IOWorkLoop and try loading the kext, I get the following
error.

kld(): Undefined symbols:

__ZN26com_linsys_driver_receiver11getWorkLoopEv

__ZN26com_linsys_driver_receiver15handleInterruptEv

__ZN26com_linsys_driver_receiver16enableInterruptsEv

__ZN26com_linsys_driver_receiver16interruptOccuredEP8OSObjectP22IOInterruptEventSourcei

You have unresolved symbols.  To determine the real name of the
symbols, use "c++filt" on the symbol name, with the extra underscore _
removed from the beginning of the symbol name.  For example:

c++filt _ZN26com_linsys_driver_receiver11getWorkLoopEv
c++filt _ZN26com_linsys_driver_receiver15handleInterruptEv
c++filt _ZN26com_linsys_driver_receiver16enableInterruptsEv
c++filt _ZN26com_linsys_driver_receiver16interruptOccuredEP8OSObjectP22IOInterruptEventSourcei

Gives you symbol names of

com_linsys_driver_receiver::getWorkLoop()
com_linsys_driver_receiver::handleInterrupt()
com_linsys_driver_receiver::enableInterrupts()
com_linsys_driver_receiver::interruptOccured(OSObject*,
IOInterruptEventSource*, int)

Now you need to determine how to resolve those symbols.  For that, I
can't help.  You have not given enough information.

Good luck.
