AVRDUDE fails to auto-detect arduino-tiny binaries on Windows about arduino-tiny

[GoogleCodeExporter]

Test sketch...
void setup( void ) { }
void loop( void ) { }

Arduino IDE 1.0.5

No dot-bin file is produced.

Hi again!

I am a member of the codebender (https://codebender.cc) team. Codebender is an 
online Arduino IDE (v1.0.5 compatible) and it uses the same toolchain in order 
to compile/upload Arduino projects. 
I do know that Arduino IDE uses hex files instead of binary, but there is a 
reason why we need to use binary files with AVRDUDE, as well as using 
auto-detection on upload.
The problem is that when compiling a project with the Arduino Tiny core (v1.0), 
the binaries are detected as invalid on Windows, whereas using the standard 
core (for example Arduino Uno), produces a valid binary.
Is there any way I can fix this?

Regards

I have used IDE v1.0.5 on Windows to compile your sample sketch for Arduino Uno 
and no BIN file is generated.

Here are the final build step as well as the AVRDUD command line to upload the 
HEX file using USBtiny :
D:\arduino\hardware\tools\avr\bin\avr-gcc -Os -Wl,--gc-sections 
-mmcu=atmega328p -o C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.elf 
C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.o 
C:\Temp\build6412160318083764428.tmp\core.a 
-LC:\Temp\build6412160318083764428.tmp -lm 
D:\arduino\hardware\tools\avr\bin\avr-objcopy -O ihex -j .eeprom 
--set-section-flags=.eeprom=alloc,load --no-change-warnings 
--change-section-lma .eeprom=0 
C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.elf 
C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.eep 
D:\arduino\hardware\tools\avr\bin\avr-objcopy -O ihex -R .eeprom 
C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.elf 
C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.hex 
Binary sketch size: 444 bytes (of a 32,256 byte maximum)
D:\arduino\hardware/tools/avr/bin/avrdude 
-CD:\arduino\hardware/tools/avr/etc/avrdude.conf -v -v -v -v -patmega328p 
-cusbtiny 
-Uflash:w:C:\Temp\build6412160318083764428.tmp\sketch_aug18a.cpp.hex:i 

As you can see no BIN file is build/used, only HEX file.
This is a off-the-shelf IDE v1.0.5 for Windows building for Aruino UNO.

However, at no point arduino-tny can influence the build process. It only 
contains CODE that has been adapted/optimized for ATtiny instead of ATMega.
the build process is defined at 99% by Arduino IDE and slighly influenced by 
boards.txt/programmers.txt
