ASIOSDK; Error when building mex file from hostsample.cpp

Question

I'm writing a c++ file to build into mex, but I got the unsolved external symbol errors with asio function like "ASIOExit". I'm building in Matlab console with mex command. I've put all headfiles and cppfiles from the AsioSDK. into one folder ad used -I to include that folder. What else do I need to include or link?

The 3 headfiles related to ASIO has already been added in include.

#include "asiosys.h" 
#include "asio.h"
#include "asiodrivers.h"

Answer 1

OK looks like I haven't included all the cpp and h files in the solution.
