Hi,

The problem is that the float* type was not mapped yet by CxxWrap. I have 
just added it, so your example should work after you 
Pkg.checkout("CxxWrap") and rebuild. Before rebuilding you may need to 
remove the usr dir in .julia/v0.4/CxxWrap/deps. Also, you need to pass a 
Float32 array to Hello.greet in Julia.

Note that I am adding functionality as-needed, so if you hit other problems 
like this feel free to create an issue on Github.

Cheers,

Bart
