Owen O'Malley commented on HDFS-13534:
--------------------------------------
To get it working with gcc 7, I had to make two changes:
{code:java}
*** lib/common/async_stream.h~ 2017-08-30 07:56:51.000000000 -0700
--- lib/common/async_stream.h 2018-06-05 22:02:35.000000000 -0700
***************
*** 20,25 ****
--- 20,26 ----
#define LIB_COMMON_ASYNC_STREAM_H_
#include <asio.hpp>
+ #include <functional>
namespace hdfs {
{code}
{code:java}
*** lib/rpc/request.h~ 2017-08-30 07:56:51.000000000 -0700
--- lib/rpc/request.h 2018-06-05 22:33:59.000000000 -0700
***************
*** 22,27 ****
--- 22,28 ----
#include "common/util.h"
#include "common/new_delete.h"
+ #include <functional>
#include <string>
#include <google/protobuf/message_lite.h>
{code}
Those don't seem to be in this patch.

> After merging HDFS-13403 [~pifta] noticed the build broke on some platforms.
> [~bibinchundatt] pointed out that prior to gcc 7 mutex, future, and regex
