Cannot build the project

Dear @yzhaiustc , Thanks for you amazing effort for this repo. However, we cannot build this project, because the helper_functions..h is missing. Can you provide such files? Thanks!

thanks for the interests.
please just remove whatever header files that cannot be found and then you should be able to compile.
I'll find time update the src code maybe some time next week.
let me know whether it turns out working for you. thanks.
