Undefined symbols for architecture x86_64

I try to compile my source file (file.cu) with nvcc on mac OSX.
I use instruction:

$ nvcc file.cu -o file

but I get the following output

Undefined symbols for architecture x86_64:

What do I do?

Hey JacopoCinosi,

This looks like a stdlib issue. I just had a similar problem on my machine. Without knowing the specifics you might have to tell nvcc to use either libstdc++ or link -lc++.

I hope this helps

Chris :-)
