geeetech i3 C pro duel extruder firmware

[robbar]

slight prob having just built this new toy i may have deleted the firmware doing the instructions from geeetech on updating the ware as my x axis was going the wrong way. have arduino 1.8 and the marlin firmware from the website but have a error coming up when compiling

exit status 1 using typedef-name 'fpos_t' after 'struct'

can you shed some light as to what is wrong and how to correct thanks

was so looking forward to the world of 3d printing but this isnt the start i was hopoing for .

[bang]

Arduino 1.0.1 may fix it.

thanks for the reply,,,
the solution was infact the ard 1.0 and not to use other newer versions,
since then ive compiled and sorted the x axis direction and fixed the endstop x axis

soon to do a print
