What if the header file conflict between HWPuSDK and HCNetSDK in Linux? I believe that many novice rookies can do nothing about this. Through the summary of this article, I hope you can find a solution.

problem

HWPuSDK.h:40:14: error: 'DWORD' was previously declared as' typedef long int DWORD'

HCNetSDK.h:30:33: error: conflicting statement 'typedef unsigned int DWORD'

The solution is as follows:

Modify HCNetSDK.h header file

Add the following code at the beginning of the file

# include "HWPuSDK.h"

Comment typedef

/ / # define BOOL int

/ / typedef unsigned int DWORD

/ / typedef int LONG

Enumerate conflicting VEHICLE_TYPE

Typedef enum tagITS_TPS_TYPE

{

LANE_VOLUME = 0x01

LANE_VELOCITY = 0x02

TIME_HEADWAY = 0x04

SPACE_HEADWAY = 0x08

TIME_OCCUPANCY_RATIO = 0x10

SPACE_OCCUPANCY_RATIO = 0x20

QUEUE = 0x40

/ / VEHICLE_TYPE = 0x80

TRAFFIC_STATE = 0x100

} ITS_TPS_TYPE

The current processing method is masking, or you can rename VEHICLE_TYPE_2.
