Time.h compile error in the Arduino 1.5.3 - Intel 1.0.4 IDE

UST · November 12, 2014, 3:16pm

Hello,

I'm new to Arduino and I used the forum before to got some great help and I'm turning to it again after doing strenuous searching on other forums and the internet.

My code below is just an empty skeleton which includes the Time.h and DS1307RTC.h files from their respective libraries; I get an error (also shown below) with regards to the Time.h file.

Now I am using a new Arduino IDE that is meant to be compatible for the Arduino-Edison breakout board, and I know this might the wrong place to ask but I have asked the Intel forums as well and I'm looking here since maybe there are others with more experience on the matter.

The error with regards to Time.h seem to be the result from the IDE thinking there are multiple declarations of functions; when from what I understand it's declarations of the specific function (hour() minute(), etc) then the same function being defined for another instance (hour(time_t t) [the hour at time specified]) ... or am I completely understanding this wrong?

Any insight or direction on how to fix the error that is shown below would be greatly appreciated

#include<Time.h>
#include<DS1307RTC.h>

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly: 
  
}

UPDATE:

If I change the default Time.h file (code below), the change being that I comment out the previous declarations of each function, I get rid of my error. But for some reason, now when I run the ReadTest example (code below) from DS1307RTC library, I get the error:

"DS1307 read error! Please check the circuitry." Which I think is happening due to me messing with Time.h, which DS1307.h is dependent on. But with Arduino IDE 1.0.6 all of this runs perfectly.

Again, any insight or direction would be greatly appreciated

UPDATE:

Read yesterday that the time.h lib is currently not compatible with Arduino-Intel IDE, hopefully this gets looked at on Intel's side. However, I also read that it might be an issue of libraries and IDE not being linked, and I might need to cross-compile them? I'm going to try and look into this today.
