Will not compile

Can anyone help me with this error message. Just in case you need to know this is for the Delta Rostock G2 3D printer

This report would have more information with

enabled in File > Preferences.

Is the marlin firmware online, so I can see it ?
You have a problem with the "MACHINE_NAME", it seems to be defined twice in "language.h". But there are other problems as well. Is that the original code, or did someone made changes to it ?

The redefine warnings aren’t what is causing it to not compile. The problem is

sketch\qr_solve.cpp:7:18: fatal error: time.h: No such file or directory

 #include <time.h>

Do you have the time library installed? I agree we need a link to where you downloaded the code.
