MX_RTC_Init undefined

[iDeew]

Hi,

I'm getting this below compile time errors...

 

 

undefined reference to `MX_RTC_Init'

 

 

However, I have included the rtc.h header file, which contains the declaration of the MX_RTC_Init(void) function.

 

 

#include "main.h"
#include "cmsis_os.h"
#include "fdcan.h"
#include "i2c.h"
#include "lwip.h"
#include "rtc.h"
#include "spi.h"
#include "usart.h"
#include "usb_device.h"
#include "app_touchgfx.h"

 

 

Why does CubeIDE still giving me this error?

Thanks

Hello @iDeew and welcome to the ST Community :smiling_face_with_smiling_eyes:.

Could you please share your .ioc file. Also, tell me the versions of CubeMX and CubeIDE that you are using.

You meant .ioc file?
Pleas see attached.

CubeMX 6.11.1
CubeIDE v1.16.0

[STTwo-32]

Could you please try using the last version of CubeMX (V6.12.0).

Best Regards.

That's a linker error - not a compiler error.

That's right: it contains only a declaration - not the definition.

The error message said that it's the definition that's missing.

The definition would be in the rtc.c source file - so check that's correctly included in the project ...

[iDeew]

Yes, you are correct. It is a Linker error.
Any idea why I'm getting it?

Thanks

Because the rtc.c source file - which contains the definition - isn't being built and/or isn't being linked.

Is it present in your Project?

As @STTwo-32 said, you could attach the Project...

[STTwo-32]

If you still have the same error. Can you send you project here. 

Best Regards.
