This is how our CI builds wheels. [ray/.travis.yml at master · ray-project/ray · GitHub](https://github.com/ray-project/ray/blob/master/.travis.yml#L206) Eventually this goes down all the paths you mentioned, but you eventually want to be calling option 1.

That warning/error you’re coming across is another example of us assuming an x86 instruction set (64 bit longs). Can you change the `2L` to `2ULL` and try again?
