Include SdFat library in other libraries not possible (?) about sdfat HOT 23 CLOSED

You will need to add an extern declaration to access the SD object you create in cpp files. I don't create SD like the SD.h wrapper for the six year old version of SdFat since there are now too many options for this to work in all cases.

extern SdFat SD;

from sdfat.

I use the Eclipse 'Sloeber' IDE instead the Arduino IDE.
The SdFat library directory is in the same directory as e.g. the SPI library and Wire library directories.
If I include SdFat in the 'program' file, it works.
I have the problem only if I want to include the SdFat library in other libraries.

from sdfat.

I don't know how you cause third party libraries to be in the include list for 'Sloeber' IDE.

Eclipse has the ability to add an include path.

Ask a 'Sloeber' expert for more help.

from sdfat.

Eclipse has included the SdFat library and shows that the SdFat library has a problem to include the ArduinoFiles.h library.
The include SdFat.h works in a 'program' file, but not if included in another library.

from sdfat.

To add a library to Eclipse is very simple.
That is not the reason for the issue.

from sdfat.

I found another issue.
Maybe it helps.
if (!SD.exists("/MY_DIR")) { SD.mkdir("/MY_DIR"); } creates the file 'MY_DIR'!!
Only SD.mkdir("/MY_DIR"); creates the directory 'MY_DIR'.

from sdfat.

I don't use 'Sloeber' and can't help you.

It's NOT a Eclipse/Sloeber problem!!!

Question:
Why works 'SdFile my_file;' and 'SdFat SD;' not in another library?

from sdfat.

This program seems to work fine.

#include <SPI.h>
#include "SdFat.h"
SdFat SD;
void setup() {
  Serial.begin(9600);
  Serial.println("Type any character");
  while (!Serial.available());
  if (!SD.begin()) {
    Serial.println("begin");
    while(1);
  }
  Serial.println(SD.exists("/MY_DIR"));
  if (!SD.exists("/MY_DIR")) { SD.mkdir("/MY_DIR"); }
  Serial.println(SD.exists("/MY_DIR"));
  Serial.println("Done");
}
void loop() {}

As I already mentioned.
The SdFat library works in a program but not in another library

from sdfat.

P.S.
Eclipse/Sloeber and Arduino use the same compiler.

from sdfat.

Ask a Sloeber user about this. The include path can be a problem when you include a library in a library.

For example, if you want to include ArduinoFiles.h

#include "ArduinoFiles.h"

May not work since the file is located at"

libraries/SdFat/src/FatLib/ArduinoFiles.h

from sdfat.

#include "SdFat.h"
#include "ArduinoFiles.h"
void setup() {
}
void loop() {
}

Arduino: 1.8.1 (Windows 10), Board: "Arduino/Genuino Uno"

C:\Users\bill\Documents\ArduinoSdFs\sketch_feb16a\sketch_feb16a.ino:2:25: fatal error: ArduinoFiles.h: No such file or directory

#include "ArduinoFiles.h"

from sdfat.

This works with the Arduino IDE.

#include "SdFat.h"
#include "FatLib/ArduinoFiles.h"
void setup() {
}
void loop() {
}

from sdfat.

Instead
SdFat SD;
use
SdFat my_sd;
because SD may be reserved.

Dear William,
Many thanks. I have written a couple of libraries for sensors and in this libraries I have included and included other libraries without problems.
The situation is, I want only to replace the old SD library with your much better SdFat library.
My libraries work all with the old SD library but the one by one replacement with your library is very difficult for me.

Dear William,
Many thanks for the important information.
You use a Uno and I use a Due.
We are using different compiler!

from sdfat.

I found another issue.
Maybe it helps.
if (!SD.exists("/MY_DIR")) { SD.mkdir("/MY_DIR"); } creates the file 'MY_DIR'!!
Only SD.mkdir("/MY_DIR"); creates the directory 'MY_DIR'.

This issue I don't have with an AVR board like an Uno.
This issue I have with a SAM board like a Due.

Many thanks stevstrong.
A very good tip.
But unfortunately the beast (issue) is still alive.

You expect me to guess you are using a Due?

I don't appreciate your all caps and !!!

It's NOT a Eclipse/Sloeber problem!!!

That does it I don't want to waste more time.

Please learn how to use Eclipse, CDT, and Sloeber. Eclipse and CDT have excellent documentation.

You need understand how gcc finds include files. It's not AVR vs. SAM. It's not the compiler.

Some libraries will work when included in a simple way. Some won't. SdFat has a more complex directory structure. The Sloeber plugin may not discover include files in a sub-directory of the 'src' folder.

I think there is a YouTube video about the include browser.

You should only need to include SdFat.h. SdFat.h includes other needed .h files.

You can always tweak the include paths in CDT. Please read the documentation.

Avr and Due both fail in this example as does STM32, Teensy 3.x, and ESP8266.

#include <SPI.h>
#include "SdFat.h"
#include "ArduinoFiles.h"
void setup() {}
void loop() {}

Arduino: 1.8.1 (Windows 10), Board: "Arduino Due (Programming Port)"

C:\Users\bill\AppData\Local\Temp\arduino_modified_sketch_210703\HelloWorld.ino:3:26: fatal error: ArduinoFiles.h: No such file or directory

#include "ArduinoFiles.h"

This works on avr, Due, and other boards!

#include <SPI.h>
#include "SdFat.h"
SdFat SD;
void setup() {
  Serial.begin(9600);
  Serial.println("Type any character");
  while (!Serial.available());
  if (!SD.begin()) {
    Serial.println("begin");
    while(1);
  }
  Serial.println(SD.exists("/MY_DIR"));
  if (!SD.exists("/MY_DIR")) { SD.mkdir("/MY_DIR"); }
  Serial.println(SD.exists("/MY_DIR"));
  Serial.println("Done");
}
void loop() {}
