çCollect2多个定义错误

Question

我写一个驱动程序FRAM的机器人，和所有突然我开始收到此错误：

C:\Users\james\AppData\Local\Temp\cciezvMm.o: In function `_FRAM_driver_setup': 
(.text+0x0): multiple definition of `_FRAM_driver_setup' 
cmm/FRAM_driver.o:(.text+0x0): first defined here

cmm/FRAM_driver.o:(.text+0x7a): first defined here 
collect2: ld returned 1 exit status 
Done. Build Failed! 

我不知道是什么导致这个事情，但我没有能够在我的代码中找到多个定义。这里是头文件：

#ifndef FRAM_DRIVER_H_ 
#define FRAM_DRIVER_H_ 

#include "simpletools.h" 

typedef struct FRAM_driver_type { 
    i2c* busID; 
} FRAM_driver_type; 

void FRAM_driver_setup(FRAM_driver_type* ptr, int sclPin, int sdaPin, 
    int sclDrive); 

void FRAM_log_data(unsigned char* string, FRAM_driver_type* ptr); 

void FRAM_read(FRAM_driver_type* ptr); 
#endif 

这里是C文件：

#include "FRAM_driver.h" 

#define FRAM_DEFAULT_ADDR    (0x50) 
#define FRAM_MAX_MEM_ADDRESS   (0x00) 
#define FRAM_FIRST_MEM_ADDR   (0x01) 
#define FRAM_ADDR_SIZE     ( 2) 
#define FRAM_DATA_SIZE     ( 1) 
#define INT_SIZE      ( 1) 

void FRAM_driver_setup(FRAM_driver_type* ptr, int sclPin, int sdaPin, 
    int sclDrive){ 
    ptr->busID = i2c_newbus(sclPin, sdaPin, sclDrive); 
} 

void FRAM_log_data(unsigned char* data, FRAM_driver_type* ptr){ 
    // Create a static integer initialized to the first memory address of the 
    // FRAM. It is 0x01 instead of 0x00 because 0x00 is going to be used to 
    // store the last memory adress being used. Also, create the int data_Size 
    // and set it equal to the length of the string plus one. 
    // 
    static int mem_Addr = FRAM_FIRST_MEM_ADDR; 
    int data_Size = strlen(data) + 1; 

    // Send the size of the data being sent to the next available memory 
    // address. This allows the FRAM_read_data funtion to know what size of 
    // data to read. Then increment up by one memory address. 
    // 
    i2c_out(ptr->busID, FRAM_DEFAULT_ADDR, mem_Addr, FRAM_ADDR_SIZE, data_Size, 
     INT_SIZE); 
    while(i2c_busy(ptr->busID, FRAM_DEFAULT_ADDR)); 
    mem_Addr += 0x01; 

    // Write data to the next address when the FRAM is not busy, then increment 
    // the memory address by one again. 
    // 
    i2c_out(ptr->busID, FRAM_DEFAULT_ADDR, mem_Addr, FRAM_ADDR_SIZE, data, 
     data_Size); 
    while(i2c_busy(ptr->busID, FRAM_DEFAULT_ADDR)); 
    mem_Addr += 0x01; 

    // Write the last memory address used to the first memory address of the 
    // FRAM. Then wait for the FRAM to not be busy. 
    // 
    i2c_out(ptr->busID, FRAM_DEFAULT_ADDR, FRAM_FIRST_MEM_ADDR, FRAM_ADDR_SIZE, 
     mem_Addr, INT_SIZE); 
    while(i2c_busy(ptr->busID, FRAM_DEFAULT_ADDR)); 
} 

void FRAM_read_data(FRAM_driver_type* ptr){ 
    // Initialize unsigned characters to receive data from i2c_in. 
    // 
    unsigned char logged_Data = 1; 
    unsigned char logged_Data_Size; 
    unsigned char last_Memory_Address; 

    // Get the last memory address written to from FRAM_MAX_MEM_ADDRESS and 
    // store it in last_Memory_Address. 
    // 
    i2c_in(ptr->busID, FRAM_DEFAULT_ADDR, FRAM_MAX_MEM_ADDRESS, FRAM_ADDR_SIZE, 
     &last_Memory_Address, INT_SIZE); 
    while(i2c_busy(ptr->busID, FRAM_DEFAULT_ADDR)); 

    // Loop through all of the filled memory addresses in the FRAM and print 
    // the logged data in each address. 
    // 
    for (int i = FRAM_FIRST_MEM_ADDR; i <= last_Memory_Address; i+=2){ 
     // Get the data_Size from the odd memory address and store it in 
     // logged_Data_Size. Then wait until the FRAM isn't busy. 
     // 
     i2c_in(ptr->busID, i, FRAM_FIRST_MEM_ADDR, 
      FRAM_ADDR_SIZE, &logged_Data_Size, INT_SIZE); 
     while(i2c_busy(ptr->busID, FRAM_DEFAULT_ADDR)); 


     // Use logged_Data_Size to store the data to logged_Data and then print 
     // the data. Wait until the FRAM isn't busy. 
     // 
     i2c_in(ptr->busID, i++, FRAM_FIRST_MEM_ADDR, 
      FRAM_ADDR_SIZE, &logged_Data, logged_Data_Size); 
     print("Log: %d \n", logged_Data); 
     while(i2c_busy(ptr->busID, FRAM_DEFAULT_ADDR)); 
    } 
} 

最后，这里是测试平台文件：

#include "FRAM_driver.h" 

#define FRAM_SCL_PIN 28 
#define FRAM_SDA_PIN 29 

static FRAM_driver_type fram_obj; 

int main() { 
    const unsigned char* data = 2; 
    FRAM_driver_setup(&fram_obj, FRAM_SCL_PIN, FRAM_SDA_PIN, 0); 
    FRAM_log_data(data , &fram_obj); 
    FRAM_read_data(&fram_obj); 
} 

任何帮助将不胜感激。另外，我正在使用simpleIDE和Propeller微控制器的简单工具库。

Answer 1

SimpleIDE包含了未包含在项目目录中的文件的备份。其实，我找不到任何地方。就好像它正在创建我正在处理的代码的备份副本，然后在我运行代码时将其存储在临时位置。该文件已从SimpleIDE项目文件中删除，然后运行。

Answer 2

C:\Users\james\AppData\Local\Temp\cciezvMm.o: In function '_FRAM_driver_setup: (.text+0x0): multiple definition of '_FRAM_driver_setup' cmm/FRAM_driver.o:(.text+0x0): first defined here

这个错误表示您的链接线是参考FRAM_driver.c两次，看起来是这样的：

gcc ... cmm/FRAM_driver.o ... cmm/FRAM_driver.c ... 

不要做是 - 这显然是行不通的。
