Error[Li005]: no definition for ''HAL_CRC_Init''

I want to add crc function in STM32F030RC, so I add HAL_CRC_Init, and related functions. But there is always 'no definition for 'HAL_CRC_Init'' error when link. I have include 'stm32f0xx_hal.h','stm32f0xx_hal_crc.h','stm32f0xx_hal_crc_ex.h', but it seems useless. I don't know why, and how to fix this problem. Please help!

Below is my related code.

#include 'main.h'#include 'stm32f0xx_hal.h'#include 'stm32f0xx_hal_crc.h'#include 'stm32f0xx_hal_crc_ex.h'

/* CRC handler declaration */

CRC_HandleTypeDef   CrcHandle;

static void MX_CRC_Init(void);

static void MX_CRC_Init(void)

{ CrcHandle.Instance = CRC;

 /* The default polynomial is not used. It is required to defined it in CrcHandle.Init.GeneratingPolynomial*/ 

 CrcHandle.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE;

 /* Set the value of the polynomial */

 CrcHandle.Init.GeneratingPolynomial = DEFAULT_POLYNOMIAL_ENABLE;

 /* The size of the polynomial to configure the IP is 8b*/

 CrcHandle.Init.CRCLength = CRC_POLYLENGTH_32B;

 /* The default init value is used */

 CrcHandle.Init.DefaultInitValueUse = DEFAULT_INIT_VALUE_DISABLE;

 /* The input data are not inverted */

 CrcHandle.Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_NONE;

 /* The output data are not inverted */

 CrcHandle.Init.OutputDataInversionMode = CRC_OUTPUTDATA_INVERSION_DISABLE;

 /* The input data are 32 bits lenght */

 CrcHandle.InputDataFormat = CRC_INPUTDATA_FORMAT_WORDS;

 if (HAL_CRC_Init(&CrcHandle) != HAL_OK)

 {  /* Initialization Error */  Error_Handler(); }

You need to make sure the stm32f0xx_hal_conf.h file in your project has the following line uncommented

#define HAL_CRC_MODULE_ENABLED

You should just need to #include 

'stm32f0xx_hal.h'

I have add 

#define HAL_CRC_MODULE_ENABLED

in 

stm32f0xx_hal_conf.h

(this was commentted before, now I modified it), but still the same problem(no definition for 'HAL_CRC_Init' )

Yes, no stm32f0xx_hal_crc.c,stm32f0xx_hal_crc_ex.c in the project tree. Now it has been fixed. Thanks a lot!

Make sure you have added the following files to the project tree

 stm32f0xx_hal_crc.c

 stm32f0xx_hal_crc_ex.c

Linker error suggests you don't provide the function bodies.
