我一直在尝试编译代码。我对 XC8 编译器很陌生。我有以下代码。

主程序

void main()
{
   bmp280_t bmp280;
   ...
   bmp280.dev_addr = 0x77;
   init_check = bmp280_init(&bmp280);
   ....
}

bmp280.h

...
typedef struct {
    struct bmp280_calib_param_t calib_param;/**<calibration data*/

    uint8_t chip_id;/**< chip id of the sensor*/
    uint8_t dev_addr;/**< device address of the sensor*/

    uint8_t oversamp_temperature;/**< temperature over sampling*/
    uint8_t oversamp_pressure;/**< pressure over sampling*/

    BMP280_WR_FUNC_PTR;/**< bus write function pointer*/
    BMP280_RD_FUNC_PTR;/**< bus read function pointer*/
}bmp280_t;

BMP280_RETURN_FUNCTION_TYPE bmp280_init(bmp280_t *temp_bmp280);
...

bmp280.c

static bmp280_t *p_bmp280;
BMP280_RETURN_FUNCTION_TYPE bmp280_init(bmp280_t *temp_bmp280)
{
    /* variable used to return communication result*/
    BMP280_RETURN_FUNCTION_TYPE com_rslt = ERROR;
    uint8_t v_data_u8 = BMP280_INIT_VALUE;

    p_bmp280 = temp_bmp280;/* assign BMP280 ptr */
    /* read chip id */
    com_rslt = p_bmp280->BMP280_BUS_READ_FUNC(p_bmp280->dev_addr,
    BMP280_CHIP_ID_REG, &v_data_u8,
    BMP280_GEN_READ_WRITE_DATA_LENGTH);/* read Chip Id */
    p_bmp280->chip_id = v_data_u8;
    /* readout bmp280 calibparam structure */
    com_rslt += bmp280_get_calib_param();
    return com_rslt;
}
...

执行此代码后，我收到错误消息

":0: error: (499) undefined symbol:
    _bmp280_init(dist/default/production\FTS_basic.X.production.obj) 
(908) exit status = 1

如我所见，没有错字。命名是正确的。我也希望结构被正确传递。

在 XC8 编译器中我需要注意什么新东西吗？

这是针对pic16f1618微控制器的。
