Yes it is not going to work without strings_sort_device.cu. So you need to compile it . It takes a while but it has to be done just once.

How much memory do I need to compile the string_sort_device.cu?

antonmks commented 7 years ago

You can modify UNROLL_COUNT parameter in file strings.h to improve compilation time.

Thank you! I'll have a try.
