I am trying to upload the Marlin Firmware to my 3D printer's Arduino Mega 2560 and I am experiencing a problem. It keeps saying:
qr_solve.cpp:7:18: fatal error: time.h: No such file or directory
#include <time.h>
^
compilation terminated.
Error compiling.
Please help as I'm lost as how to fix it, because I try to scroll up to see what is highlighted in red and I can't find anything.
From Gerben's link to the googlegroups's thread, Delta robot 3D printers › compiling jcrocholl's Marlin (Ubuntu), as Francis Mallet points out, at the bottom of the thread, it is necessary to change <time.h> to "Time.h":
I copied the content of the Time library right in the Marlin folder, then changed line 7 of qr_solve.cpp from #include to #include "Time.h"
The code compiled and everything seems to be working ok.
So, to iterate, the line in qr_solve.cpp:
#include <time.h>
becomes
#include "Time.h"
Now, Marlin.ino should compile as expected.
Note that the latest version of Marlin, from github.com/MarlinFirmware/Marlin no longer suffers from this issue, but older versions of the software, such as github.com/gpfwestie/kossel_2020_sintron will do, due to line 7, in qr_solve.cpp.
interestingly changing to Time.h didn't work for me (arduino sdk 1.6.9) however commenting out the include line did...
As Gerben points out, the solution is to change to "Time.h".
