私はコードをコンパイルしようとしています。私は XC8 コンパイラを初めて使用します。次のコードがあります。
main.c
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;
}
...
このコードを実行した後、次のようなエラーが発生します

_bmp280_init(dist/default/production\FTS_basic.X.production.obj)

ご覧のとおり、タイプミスはありません。ネーミングは正しい。また、構造が正しく渡されることを願っています。
XC8 コンパイラで注意する必要がある新しいことはありますか?
