错误：在'：'标记前应有'='，'，'，';'，'asm'或'__attribute__'

Question

An error occurred when i uploaded this code to Arduino Atmega2560. This is a libary file which i have created for the .c files in my program.

The error is:
herkulex.c:16: error: expected '=', ',', ';', 'asm' or '__attribute__' before ':' token

The word 'class' is highlighted when the error appears, which is in the file (code shown below)

#ifndef herkulex_lib
#define herkulex_lib

#include <Arduino.h>
#include <Wire.h> 
#include<inttypes.h> 

class herkulex
{
  public: 
    herkulex();
    void hklx_Init(unsigned long ulBaudRate);
    void hklx_SendPacket(DrsPacket stPacket);
    unsigned char hklx_ucReceivePacket(DrsPacket *pstPacket);
    void hklx_RemoveInvalidData(void);

//no private  
};

#endif /* HERKULEX_H_ */

May I know what's wrong with this code? Thanks!

Answer 1

You are compiling a C file which contains C++. The C compiler is rejecting C++ syntax.

Compile it as a C++ program instead.

Answer 2

是不是有一个space在这里失去了:?

#include<inttypes.h>
