[LLVMdev] LLVM ERROR: Program used external function 'printd' which could not be resolved!

[António Saragga Seabra]

Hi,

That seems really simple... just changing the function pointer. But how to
do it for the 'printd' function in the Kaleidoscope example?
An example how to do this would be super-great.

Any help will be much appreciated. Thanks!
