Line 72: int n = g0.length;

Apparently, you're compiling to 32bit on Windows, and to 64bit on 
Ubuntu.
g0.length is of type size_t which is as large as your target 
bitness. int is always 32 bits large. Since you can't cram 64 
bits into 32 bits, the compiler complains when targeting 64bit.

Change that line to this: size_t n = g0.length;
