Hi, I think this might be small mistake, but I cant seem to find the solution.

Im getting the error above and the Arduino tries to explain what is going on.

In file included from BotanicallsTwitter2.cpp:3:

/Users/marco/Documents/Arduino/libraries/Twitter/Twitter.h:21:25: error: EthernetDNS.h: No such file or directory

BotanicallsTwitter2.cpp:27:138: error: EthernetDHCP.h: No such file or directory

BotanicallsTwitter2.cpp: In function ‘void setup()’:

BotanicallsTwitter2:103: error: ‘EthernetDHCP’ was not declared in this scope

BotanicallsTwitter2.cpp: In function ‘void loop()’:

BotanicallsTwitter2:142: error: ‘EthernetDHCP’ was not declared in this scope

can you help me out?

thanks

Did you install the EthernetDHCP library as described in the Customize page? Double-check that, and if you’re sure you’ve got all the libraries where they should be, let us know which version of the Arduino IDE you are using.

I believe I installed all the libraries. They are all in a folder called libraries inside the Botanicalls folder. I imported them using Sketch/add library

I also added the DHCP files that end .h and cpp.

I erased my Arduino and installed it again.

I get all these errors

I already switched to Arduino 0018, still get same errors.

This should work. It sounds like your path to the libraries is broken. What’s the current path to, for example, EthernetDNS.h ?

Would this be the path?

Documents/Arduino/BotanicallsTwitter2/libraries/ArduinoEthernet/EthernetDNS/EthernetDNS.h

This seems right no?

No the correct path would be ~/Documents/Arduino/libraries/ArduinoEthernet/EthernetDNS/EthernetDNS.h

Check the library documentation linked to online.

I was following this,

Libraries go into the main Arduino document folder. Here’s some instructions from the Arduino site “To install third-party libraries, create a directory called libraries within your sketchbook directory. Then unzip the library there. For example, to install the Twitter library, its files should be in the/libraries/Twitter sub-folder of your sketchbook folder.”

and I have also tried putting the libraries where you told me.

I have libraries now in both places, but still cannot compile the code.

When I do import library Ethernet, I see no new line at the top like the other libraries. Do you think this might be the issue?

It seems I had to have each library in its own folder within libraries, not within the ArduinoEthernet. Thanks!

However….
