[kusamba]

some strange error occurred

do someone has suggestions?

proto file: common.proto

syntax = "proto3";

package uc_netmsg;

message CSayHelloRspPara {

    int64 m_RspTime = 1;

}

#include "common.pb.h"        

uc_netmsg::CSayHelloRspPara stParam;

stParam.set_m_rsptime(0x12345678);

compile error:
