Code compiles with Arduino IDE, but does not compile with scons

[tpimh]

I have Arduino IDE 1.0.1 with it's libraries on Linux and Arduino with ATMEGA8 microcontroller.

Compiling example sketch (https://github.com/suapapa/arscons/blob/master/arscons.ino) with Arduino IDE for ATMEGA8 is okay, compiling for ATMEGA328P with scons is okay too, but if I execute "scons ARDUINO_BOARD=atmega8", I get this:

scons: Reading SConscript files ...

Looks like errors in Arduino libraries, but it's okay, when using Arduino IDE. Don't know how to fix it.

I'm using the arscons with Ubuntu 12.04 with arduino-core package.

$ dpkg -s arduino-core
Package: arduino-core
...
Version: 1:1.0+dfsg-9
Depends: gcc-avr, avrdude, gcc, avr-libc
...

No such a problem in my case. You have two solution:

1. Find out what's diffrent between the IDE and arscons, fix arscons and, send me pull request. Refer Hacking page
2. Wait till the ubuntu package upgraded to v1.0.1 so, I have same problem. :)

Works fine for me with debian sid, arduino-core 1:1.0.5+dfsg2-1

Ubuntu 12.10 (quantal) and 13.04 (raring) both have arduino-core >=1.0.1
