Windows/Linux/Mac Eclipse plugin to compile and upload arduino sketches

Monkeyknight Thanks for trying this out on OS X. I don't own an OS X operating system so I can only help you with theory and experience from the port to OpenSuse. The plugin code uses a full path to locate the avr-g++. For windows and Linux this means that adding avr-g++ to the path doesn't help. I guess this will be the same on OS X. In windows avr-g++ comes packaged with the IDE. In Linux it is not. Is avr-g++ delivered as part of the IDE in OS X? Because avr-g++ is delivered differently per OS a part of the porting includes having setting different paths. You can however set the paths yourself. As an experienced eclipse user that should be a piece of cake.

To set the paths yourself, as a work around, you do as follows: Locate avr-g++, GNU make, the AVR header files and AVR dude on your system. (You don't need atmel part description files) open eclipse and go to windows->preferences->arduino->paths. You should see something like this: In your situation there will be errors. Change the paths. Try again and hope there are no other incompatibilities.

Important Notes 1) you will have to fix all the errors before you can save the preferences. 2) Do not open any other tabs in the preferences as this may invalidate the changes you do. 3) Best is to do the change, save, reopen the preferences, validate whether the change is done, if ok do cancel else redo.

If it works it would be nice if you told me what you had to change. This way I can modify the plugin to set these values correct. Even better was if you changed the plugin yourself (with my help off-course).

Lots of good luck Jantje

HA! Sweet!

All is great, except for some includes now!

But this should be pretty simple.

I have some years of Eclipse experience, but to be honest most of the times I have used it I have not had to edit many paths. So this was not quite as obvious of an edit as it would have been to some.

Arduino Paths.tiff (131 KB)

The library was not building, because of some undefined refrences.

I had to add “#include <stdint.h>” to Arduino.h. I am not sure why, and in fact I am sure that I should not have to edit any of the Arduino core files.

Also I had to edit

#include "pins_arduino.h"


#include <pins_arduino.h>

Here are a few other edits:

pins_include.tiff (194 KB)

AVR Compiler Path.tiff (228 KB)

AVRDude Conf dir.tiff (109 KB)

I am not sure why, but the plugin will not take my edits for updating the avrdude path.

I edit it to point to: /Applications/

But it resets it to: /Applications/

Hi Monkeyknight I see you are using Arduino 1. The plugin is not compatible with Arduino 1. See my post on this topic in,81082.0.html You should not have to edit the Arduino files. If the IDE works under OS X with these files there is no reason an eclipse plugin should have to change these files. The only change you made that I can not explain is "I had to add "#include " to Arduino.h"

On behalf of "I am not sure why, but the plugin will not take my edits for updating the avrdude path." Have you followed the "important notes" in my previous post?

I see you are changing things in the project settings. Normally this is not needed. If you want to change it anyway it is better to change them in project properties-> C++- general > paths and symbols. Information is stored at several locations and you may undo your changes without knowing.

I'm wondering what you provided as input to the preference screen below. Given your input it should work if you provide "/Application/" Can you try to change to this settings saave the preferences reopen the preferences and take a image from the avr path settings Delete all the project (or even the workspace) selecting delete content on disk before you do a new test. As far as I see it should work. Best regards Jantje

I just did an uninstall of Eclipse and deleted all my workbenches, and reinstalled on my Mac Mini. Life is good! Now I just have to do it to my Mac Book Pro's.

This is just killer! Perfect. After a bit, I think that I am going to look into porting over to the IDE version 1.0 though. It is kind of a downer that I have to use an old version of the Arduino IDE, but I tell ya what - It's still flippin' awesome!

Many thanks to you! May your code always compile the first time.

Thanks, Nicholas

I'm testing your plugin un my linux (ubuntu 11) with an arduino Nano. I'm having some linking problems with the arduino_atmega328p autogenerated project: ‘init’ was not declared in this scope main.cxx /arduino_atmega328p/arduino line 3 C/C++ Problem ‘loop’ was not declared in this scope main.cxx /arduino_atmega328p/arduino line 8 C/C++ Problem ‘setup’ was not declared in this scope main.cxx /arduino_atmega328p/arduino line 5 C/C++ Problem Symbol 'DDRB' could not be resolved pins_arduino.c /arduino_atmega328p/arduino line 361 Semantic Error Symbol 'DDRC' could not be resolved pins_arduino.c /arduino_atmega328p/arduino line 362 Semantic Error Symbol 'DDRD' could not be resolved pins_arduino.c /arduino_atmega328p/arduino line 363 Semantic Error ...

Am I missing something?

Nicholas Are you saying the plugin work fine on OSX with Arduino IDE 0023? That would be great.

turdusmerula The init, loop and setup sound unknown to me. Does you code compile? if so please read the section "Eclipse tells me there are bugs in my code but it compiles ok." in the faq at How do you get to main.cxx? I have main.cpp?

About the errors in pins_arduino.h see "There are errors and warnings in the Arduino library." in the same FAQ

Note that in 1.0 these errors have been fixed :D

Keep me posted

I am not positive which version it is. I didn't take a look. I will next time I boot it up though.

Thanks again!

Okay solved my problems. I just have to tell eclipse to exclude the main.cxx file from build and it works !

On ubuntu we have the 0022 installed and your plugins works, really great job thanks a lot :)

One remaining question, where can I find on eclipse the output logs emitted by the Serial.print() command? thought I'd find it in the Console window but I failed.

turdusmerula You need a serial communication program with the eclipse plugin. I use the serial monitor from the arduino IDE. I'll make a todo to add this to the FAQ. Best regards Jantje

Jantje: You need a serial communication program with the eclipse plugin. I use the serial monitor from the arduino IDE.

Thats what I was doing ;) I use the cat command, it works far better than the arduino IDE in a good console emulator in Linux cat /dev/ttyUSB0 Just make sure that the bitrate selected in eclipse is the same than the one given in the Serial.begin(). Note that the cat must be killed before trying an new burn of the arduino.


Txs for the linux tip on to use cat. I'm still working on the 1.0 compatibility. Best regards Jantje

All 1.0 compatibility is fixed. And I wanted this thread back on top 8) Best regards Jantje

Hello Jantje. I now only use your plugin as primary tool for my projects, it is pretty stable and very usefull :)

One thing i noticed, do not make a cancel during a burn of the arduino even if the burn is not working because the serial port remains locked (hard disconnect of the arduino seems to be enough to solve this).

And one request: would it be hard to offer the possibility to choose a different serial port for different project? for exemple to have a TX arduino project on serial 1 and RX arduino project on serial 2.

Do you know a plugin or third party tool I could use to remote debug on the arduino and do step by step?

turdusmerula txs for the update. I'll add your comment on cancel to the FAQ. As to your request. Have you tried it. I mean the latest version "Should" support this (the 1.0 compatible one). I haven't tried though. To make it work just change the project preferences->arduino->arduino for the 2 projects (not the libraries) to point to the correct com port. I have read numerous posts on debugging. as far as I understand it states: pay money or expect very low level support. Let me know if it works. Best regards Jantje

I've updated to your latest 1.1 and tested it again. I got the same behavior than previously, when I select a serial port it is set for all projects not just for one. I also tried to use a specific programmer configuration (preferences->arduino->AVRDude) for each project with an overrided serial port but the serial port used at the end is the one in preferences->arduino->arduino. This parameter seems to be at the workspace level even if we can set it at the project level isn't it?

turdusmerula I checked this in the code and indeed I use the last used upload port and not the upload port set in the project. I'll fix this. Best regards Jantje

All The comport issue is fixed in 1.1.3 In newly created project there will be a define ARDUINO that is equal to 0023 for version 23 and 100 for version 1.0 the version info is based on the content of the versions.txt file in the lib folder of arduino. This allows to do things like

if (ARDUINO >= 100)

include "Arduino.h"


include "WProgram.h"


Best regards Jantje

Hi, and thanks for the guide..

I have followed the installations steps, and that works fine. When I try to make a new project with my hardware >> Arduino Mage (AT mega1280) << I get an error messages : Failed to create project xxxxx , Path variable name cannot contain character: (.

After that it is not possibly to compile correct or uploade. If I try to make a another project with a >> Arduino Uni << Hardware (I don’t have that board) , the project are created without any problems, and I can compile correct ?

What can I do ?

Happy new year.
