There are many ambiguous parameters

[whu-zhigao]

@stijnh , I complied your code on ubuntu 16.04 with CUDA 8.0 and GCC 5.4. There is no problem when I make main and convert. But it shows many ambiguous parameters when I compile the GPU version by using the commend ‘make main-cuda’.

The detailed errors are shown as follows, would you please let me know how did you make it successful?
