If you want to make a type (3), then add a main function and use it as your entry point. Another way is execute the assembler in a command console and only use Eclipse as an editor. If your program is type (1) you may be able to bypass the linking phase but to do this you will need to change the tool chain to not call the linker. The following link shows how but I can't readily find the option so I'm not sure it's still available. You may also need to specify the entry point.

When using GCC to execute ld you need to use -Wl, for some options. If your program is type (2) above, you may be able to avoid dragging in the C library by using the GCC loader options -nostartfiles, -nodefaultlibs, and -nostdlib during the linking phase.

I don't know which you are trying to make plus I'm not familiar with the device you are building for. Your program can take one of three forms:Р В РІР‚СњР В Р вЂ№) it can startup the way an OS would start (that is, it is the OS)Р В РІР‚СњР РЋРЎвЂє) It can be started as a program by the OS which eventually tells the OS when it is done

The error you are seeing is caused by GCC adding the startup code which wants a main function. These are then linked together along with other objects from libraries to form an executable. Modules are normally created in object format by compiling and assembling. When the program is done, it returns to the exit code which ends up returning to the OS.

When the program is executed the entry point is in the startup code.Р В РІР‚СњР вЂ™Р’Вuring startup execution it will call main. In C, the startup and exit code is in the standard C libraries. Eclipse is expecting objects will conform to the C layout model. You should NEVER return from main().You need to understand how a C program is run. $Р В РІР‚СњР В РІР‚С›nd the 'Command' to avr-gcc instead of avr-g++ (may be already be the default if you're making a C project instead of a C++ one)Р В РІР‚СњР В РІР‚С›VR C++ Linker/Objects : Add the core.a file you've imported and maybe renamed from the Arduino library.

YOu'll have to install it on a Windows machine, anyway. You'll also need a folder named PartDescriptionFiles which you can get from an installation of AVR Studio. This means setting up folders on where to find the different avr binaries and config files. Tutorials and binaries exists everywhere for many platforms, I'm not going to double them here.Р В РІР‚СњР В РІР‚РЋirst, configure the AVR Plugin in the Preferences window.

So, first : This have been done on Eclipse 3.3.2 (Europa), on Mac OS X.4. It is fairly incomplete, so I'm posting it here for interested people to maybe comment and extend it in order to make a complete step-by-step.

As I said, here's a little how-to on how to setup Eclipse to program the Arduino.
