Error compiling for board Arduino Nano 33 ble

sachamarbacher commented 4 years ago

i tried to use the library with the folowing hardware:

arduino Nano 33 BLE
adafruit addaloger feather if i use the standard SD library for to write or read to the sd card everything is working fine. now i nee longer file name then 8.3. but everytime i try to compile every sketch example out of the SdFat-beta i get the same error:

Please help me...

in these exemple i used the sketch "Sdinfo"

Error Message:

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

Looks like the Nano 33 BLE board package has a bug for use of fcntl.h

This sketch gives the same error.

#include <fcntl.h>
void setup() {
}
void loop() {
}

SdFat-beta must use this file to avoid problems with other boards. You can try editing SdFat/src/SdFatConfig.h to not use fcntl.h.

At about line 195 set USE_FCNTL_H to zero like this.

#elif defined(__arm__)
// ARM gcc defines open flags.
#define USE_FCNTL_H 0  // <<-- was 1 
#elif defined(ESP32)

This seems to eliminate the compile error but may cause other problems. I don't have a Nano 33 BLE to test.

Hi Greiman

Thank you very much! I just Updated the SdFatConfig.h file like you told and now the example works perfect.

Greetings Sacha

I encountered the same error on a Nano 33 BLE Sense. Found this, which solved the compile problem for me:
