@xiaofengren Thanks for reporting this. Adding #include <numeric> in src/dlc.cc probably could solve the problem.

@xiaofengren thanks for bringing this up, we've been able to build it on A1 instance with AARCH64 Graviton, Ubuntu 16.04 and GNU 5.4.0. We'll add this header for better compatibility with different platforms.

@zhiics @ziyu-guo thank you so much for your quick response. After follow your suggestion, I'm able to build successfully.
