WebBasically, we make cython believe we will use 64 bit int to generate the .c file, but by using a C header we will, in fact, define a 128 bit int (the definition in the .h file does not match what we put into the pyx file). Once Cython has generated the .c file, we can compile it with GCC without further trouble, as GCC does support 128 bit ints Raw WebCython uses the normal C syntax for C types, including pointers. It provides all the standard C types, namely char, short, int, long , long long as well as their unsigned versions, e.g. unsigned int .
