Arduino+Eclipse @Ubuntu @vmware @Win7-64bits

This is what a difficult day!  Let me write down my work quickly for memory dump....



At the first beginning, I just want to programming Arduino (or AVR in C) on Eclipse CDT under my Windows 7 64bit machine. However, I have no idea why Eclipse did not recognize Cygwin GCC.  I google and check many articles and follow the instructions (e.g. Environment variables, registry...etc).  It does not help.
Okay, so I give up and switch to Ubuntu (where it is installed in my USB HD as portable).  Because I need to use Win7 for other work, I decided to use VMware to boot the USB HD as what I did before.  Ah~~ It fails again!  An error popped from Vmware about the Physical Drive problem.  I spend 1/2 days to solve this problem.  The solution is simple:
* Start VMware as Adminstrator *.....

OMG~! after solving the HD problem, Ubuntu starts with error.. it halts for no reason.... When I boot it normally (not under VM), it works very well.... Why it is not working in VM?  I find out the cause after 2 hours: I have installed the Nvidia driver in Ubuntu before...  So, I uninstall the packages and boot... Good.  Ubuntu can be run in VM now.

So, the next task is setup the Eclipse (following online tutorial).  It is not difficult when I follow the instruction:
 http://www.arduino.cc/playground/Code/Eclipse

However, the last part is not very clear and I need to solve it by trial-an-error.  The following are the note:

1. Create a project to build the static library for Mega2560 (that's what I am using now)
2. Follow the instruction and create a sample project (e.g. Blink).  It will be cloned for future use
3. It needs special setting for AVRdude:
1. For Mega2560, protocol is STK500 V2
2. Use default baud rate or 1152000 (I guess, not yet tested)
3. Port in Ubuntu is: /dev/ttyACM0 (not ttyUSB).  It is easy to check the port under Arduino IDE
4. Setup the C++ setting for both DEBUG and RELEASE
5. Header fix is not working, I leave it
6. Messed up with main.c and main.cxx.... I use main.c and modify it:
1. Put the include for
2. Put(copy) the setup, loop function from what we did in Arduino IDE

Finally, I can program the Blink test in Eclipse and upload to my Mega2560 directly.  I also notice that the complied size in Eclipse is bigger than Arduino IDE.  I believe we can do better optimization in linker/compiler setting.  It could be the next step in future...

Time to bed....
