SdFat Linking Issues

system · January 19, 2015, 6:04pm

Hello All,

I am fairly new to programming the Uno and need help with getting SdFat to link. I am using IDE 1.0.6 on a Debian Wheezy box. I followed the instructions at http://arduino.cc/en/Guide/Libraries I downloaded SdFat.zip and installed it through 1.0.6->Sketch->Import Library... SdFat was installed in my sketchbook/libraries/SdFat directory and the SdFat library appears in the Sketch->Import Library menu.

I see ~/sketchbook/libraries/SdFat when I echo $LD_LIBRARY_PATH

However, I can not get any of my sketches to link to the SdFar libraries. I can link to the SD libraries fine.

Any ideas?

Thanks,
Murrah Boswell

What do you mean? What message do you get? What sketch? What error message?

Thank you for your response, sorry to take so long to get back to you response.

Listing of example sketch SdFatRewrite:

What version of SdFat are you using?

SdFat/SdFatUtil.h:27:22: warning: WProgram.h: No such file or directory
In file included from SdFatRewrite.pde:9:

This is from a really old library that can not be used with Arduino 1.0 or newer

Try this version of SdFat.

The library is not installed in the correct place. You must manually install the SdFat folder in your libraries folder.

See the Manual installation section here.

system · January 22, 2015, 4:09am

I installed the SdFat library automatically using the 1.0.6 IDE and it got installed in my .../sketchbook/libraries directory. Then, at your suggestion, I removed it from my sketchbook/libraries folder and reinstalled it manually in my ../arduino-1.0.6/ibraries directory and got these errors trying to compile bench:

Please read this Arduino page again and follow it! I said manual installation.

You must place the SdFat folder, in the sketchbook libraries folder. the path to SdFat.h must be

/home/otrcomm/sketchbook/libraries/SdFat/SdFat.h

system · January 22, 2015, 4:11pm

Hello fat16lib,

Thank you for your patience. Now I understand. I did copy the SdFat directory with SdFat.h into my sketchbook/libraries and as you said, that was the solution. I can now link to the SdFat libraries.

Thank you very much,

hello,

have same error....

I try to use this project.

The arduino 1.5.8 install path on my windows 8 x64 is: E:\Downloads\Arduino\arduino1.5.8_homeduino
The path to SdFat.h library is C:\Users\Packy\Documents\Arduino\libraries\SdFat\SdFat.h

gives:

FunkcontroloverNet.ino:13:19: fatal error: SdFat.h: No such file or directory
compilation terminated.

So i moved the SdFat.h library to E:\Downloads\Arduino\arduino1.5.8_homeduino\sketchbook\libraries\SdFat\SdFat.h

gives:

FunkcontroloverNet.ino:19:1: error: 'Sdvol' does not name a type
FunkcontroloverNet.ino: In function 'void setup()':
