在搞ndnSIM当毕业设计，ns3 + ndnsim + sumo + ns3-gym编译存在冲突：

                 from ../contrib/ndn4ivc/apps/fgfxf-rsu.cc:25:
./ns3/sumo-TraCIConstants.h:328:21: error: expected identifier before numeric constant

解决方案：
先引入sumo，再引入ns3-gym。并解决冲突预定义。

#include"ns3/traci-client.h"
#undef TYPE_DOUBLE
#undef TYPE_STRING
#include"ns3/opengym_interface.h"

请称我为最强！
