So i got me a 3d printer and it use marlin firmware. i was told to use (tevo marlin community firmware- tevo facebook page)but its got an error when i try compile
Arduino: 1.8.2Board: ATmega2560 (Mega 2560)"
In file included from sketch\SdFile.h:27:0,
from sketch\cardreader.h:8,
from sketch\Marlin_main.cpp:44:
SdBaseFile.h:199: error: 'Fatpos_t' has not been declared
void Getpos(Fatpos_t* pos);
SdBaseFile.h:203: error: 'Fatpos_t' has not been declared
void Setpos(Fatpos_t* pos);
exit status 1
'Fatpos_t' has not been declared
i had originally the fpos_t error but changed them all to Fatpos_t, to correct original problem however now i got the error above, and can't seem to figure it out? any help would be awesome..
thanks 
You need to ask on a Marlin Forum or on the RepRap Forum where people are familiar with that software.
This Forum is for helping people write their own Arduino programs.

Excuse me 
, but it is an arduino written program called "tevo marlin community firmware" (community is the key word it means real people wrote this program bunches of them), compiled on an arduino ide, and trying to upload to a generic arduino mega, and also it is based on the same rules and principles than govern an arduino program. I am not quite sure how much more arduino that can get. I see other user on this forum post all sorts of programming question that they are using on an arduino or a generic version to operate all sorts of things robots, autonomous vehicles, boats, airplanes, helicopters, drones, vacuums, run the house lights, garage door, operate solar power systems, hydro, wind powered, run weather stations, design music players, monitor security systems, and of coarse run 3d printers. They all use arduino based programs. So your telling me all the other users have placed there questions in the wrong forum as well.

No. Just you.
More seriously, this is not the best place to get the info you need. It's like going to a Ford dealer looking for warranty assistance with your Volkswagen.
Marlin is a very complex off-the-shelf program and you need to go someplace where people are familiar with it.
Hang out here for as long as you want.
