I’m building on macOS with latest CUDA 8.0 and Apple LLVM 8.0.0 and HEAD of your repo. If this is a macOS thing, feel free to close—I’m building it here just to do some basic testing, I will find a Linux box with a more modern GPU and test there.

Hello,

I'm sorry, but I do not have access to a macOS system, but you could try to remove the mexPrintf calls since they are just used for debugging issues.

Ran into the same issue on Ubuntu 16.04. Removing the following if statement from matlab_helper.h (starts at line 112) solved the issue.
if (is_int) mexPrintf("%s: %d, ", name, (*data)[i]); else mexPrintf("%s: %f, ", name, (*data)[i]);
