    This is a warning, not an error. You can ignore it unless you want to use gettimeofday, in which case you have to implement it yourself for an embedded system :).

     I checked the ID file and found no gettimeofday so I don't know where this coming from and how to make it go away or I have to wait for next revision release by ST?

    is there code snips to add in gettimeofday

    I got the same error after performing "Check for Update" and patching CubeMX to 6.19.1 and CubeIDE to 1.13.1.

    This compiling error should be fixed, but no just be ignored.

    Same here. Tried rebuilding a code from prior CubeMX / CubeIDE version. Prior to the 2 of August 2023.

    Guys, I have this problem after IDE upgrade to 1.13.1.

    This topic is marked as "solved", but nobody specified how it was solved. Could somebody write the solution, please?

      or if you trust more in compiler :

      I would like to help other so I created the gettimeofday.c and then added a function that return just 0 since I'm not using it but it resolve compiler error with some peace of mind. 

      #include <sys/time.h>

int _gettimeofday( struct timeval *tv, void *tzvp )
{
 // you can add code here there many example in google search. 
 return 0; // return non-zero for error
} // end _gettimeofday()

        Made a new gettimeofday.c source file in src folder and this worked, thanks!

        Our application doesn't use gettimeofday. It's not clear to us why we need to implement it.

        Thanks.

        Hi,

        If you are using mbedTLS a solution to get rid of this warning is to not activate MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE in mbedtls_config.h

        regards

        Patrice
