Cannot Compile

[PhunkMaster]

When attempting to compile with Arduino IDE 1.6.10 I am getting the following error:

Arduino: 1.6.10 (Windows 8.1), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I have the same problem. I believe the problem is caused by a new release of avr-libc, where a type with the same name as the one used in sdfat library is introduced.

In upstream SdFat this struct has been renamed to FatPos_t: https://github.com/greiman/SdFat/blob/master/SdFat/SdBaseFile.h#L60 Either do a search&replace in SdBaseFile.{h, cpp} and replace fpos_t with FatPos_t or sed it:

sed -i 's/fpos_t/FatPos_t/' SdBaseFile.h

sed -i 's/fpos_t/FatPos_t/' SdBaseFile.cpp
