EthernetShield WebServer compile errors

Projects Networking, Protocols, and Devices
1

I have the arduino uno r3 connected with the ethernet shield. When I try to compile the example WebServer project (or any project from the Ethernet examples) I'm getting SPI compile errors.

On this board is also an SD card interface present, and the SD example is compiling (and running) just fine. I just can't get to get the Ethernet examples to work. I have tried copying the library to the sketchbook folder, but no luck.

I'm using ARDUINO 1.0.1 - 2012.05.21 on ubuntu.

Is there something missing?

Did you include the SPI.h file?

#include <SPI.h>
#include <Ethernet.h>
// rest of your code

Yes, the spi.h file is included. I haven't touched the example code.

I'm using Ubuntu 11.10, and I do not get those errors. Did you download and install the Arduino IDE from the Ubuntu repository first? It is v0022, but has all the avr-gcc and avr-libc updates.

edit: Install IDE v0022 from the Ubuntu Software Center in your launcher.

That fixed the problem. Thank you. :smiley:

Time for real fun!
