Redefinition of struct stat #204

Open victorromeo opened 4 years ago

victorromeo commented 4 years ago

SdFat Version 1.1.4 Arduino IDE - 1.8.12 Board - Arduino Nano 33 BLE Sense

When compiling the out-of-the-box RawWrite example I'm getting a compilation error, caused by colliding definitions error: redefinition of 'struct stat'.

May I get some advice how to proceed?

I don't use the struct stat which is defined in the system file fcntl.h.

mbed_retarget.h has a definition that conflicts with the stat in fcntl.h

You can try editing SdFatConfig.h and set USE_FCNTL_H zero. This may cause other problems.

Arduino or mbed should do something to fix this.
