I am trying to decipher the console output below when building an SBL2E project. It seems to be telling me that it can't find code for a function called gettimeofday, but this must be a low-level call as it's not one I called directly. Any ideas? I did a rebuild all on the system files... I'm using Rel24_rc2.

Thanks

Looks like the trouble is with the call to the function: time() from time.h:

I have the function:

Code: Select all

time_t GetSysTimeAsTime_t(void) {
	time_t SYS_time_t;			// Create a time_t variable to hold System time.
	time( &SYS_time_t );		// Load it with the system time.
	return SYS_time_t;
}

If I comment this out, things compile OK....
Workarounds?
