Make project compile in Eclipse and using arm-none-eabi-g++

[kigster]

Turns out it is not necessary to break every file in to .h and .cpp. All that is needed is to declare some of the variables used in each class as extern, so that compiler can resolve them later.

I also had to create a header file for the main .ino file so that functions used there could be called from other classes. Finally I updated .gitignore with lots of Mac/Eclipse specific ignores.

The project now gloriously compiles in Eclipse, as well as in Arduino 1.0.6 (updated to be used with Teensy).

There are quite a few warnings that can be fixed, but that's a separate issue.

I would love for someone to test this out on Windows and/or other environments and make sure this does not break anything for the conventional Arduino IDE users.

Here is the command that Eclipse generates the following command ($MY_ARDUINO_HOME is what I put in instead of my private arduino dir:

This PR fixes #7

[kigster]

Anything else remaining to do before this is merged?

[jasoncoon]

Only a little more time to review the changes. :) I've only done a quick test to make sure most functions work. I'm not planning to merge this pull request directly to pixelmatix/aurora/master. I merged from your fork to the eclipse branch (https://github.com/pixelmatix/aurora/tree/eclipse). I plan to merge the eclipse branch to master for the next release. I'm trying to keep master fairly stable and well tested.

[kigster]

Got it, thanks! I think the changes are pretty safe, but I totally understand the caution.

[jasoncoon]

OK, sorry for the delay, against my better judgment I had a lot of changes that I was sitting on. I've created a new branch that contains all of our changes merged together: https://github.com/pixelmatix/aurora/tree/Aurora1.3

Would you mind checking it out and testing in Eclipse for me? I'm fairly certain the new files I've introduced are going to cause you more problems, sorry. I still have not gotten Eclipse set up so I can test locally, and I'm honestly not sure I want to. Do you mind being the designated Eclipse tester? :)

[kigster]

I do not mind at all being the Eclipse tester! It's very easy, I already have a project checked out and working under Eclipse.

Just tested it and it compiles without any problems. Here is the last few lines of output:
