Salutations... I have a new project and when I have everything compiling I noticed that it failed to create a .hex file. here is a few lines from the console:

End of search list.
avr-objcopy -R .eeprom -R .fuse -R .lock -R .signature -O ihex ds18b20_temperature.hex "ds18b20_temperature.hex"
makefile:76: recipe for target 'ds18b20_temperature.hex' failed
Finished building: ds18b20_temperature.hex

The filename ds18b20_temperature.hex is the output file name, but somehow gets placed as the input filename also. It should be just the ds18b20_temperature.elf file that is the input. I've done it via the CLI, so it works. Where is it getting the .hex for the input??? The project name is "ds18b20_temperature", so I must have configured something erroneously. I've spent a number of days trying to figure this out and I thought I'd ask for assistance as I'm about to just re-do the project...

Thanks

Jack

What plug-in are you using? Is this Arduino or something else?

I was reading through the make file and had these:

# All Target
all: ds18b20_temperature.hex secondary-outputs

# Tool invocations
ds18b20_temperature.hex: $(OBJS) $(USER_OBJS)
@echo 'Building target: $@'
@echo 'Invoking: AVR C++ Linker'
avr-g++ -Wl,-Map,ds18b20_temperature.map,--cref -mrelax -Wl,--gc-sections -L/home/jack/mnt/dev-test/eclipse/seq_led/Debug/libraries -mmcu=atmega328p -o "ds18b20_temperature.hex" $(OBJS) $(USER_OBJS) $(LIBS)
@echo 'Finished building target: $@'
@echo ' '

ds18b20_temperature.lss: ds18b20_temperature.hex
@echo 'Invoking: AVR Create Extended Listing'
-avr-objdump -h -S ds18b20_temperature.hex >"ds18b20_temperature.lss"
@echo 'Finished building: $@'
@echo ' '

ds18b20_temperature.hex: ds18b20_temperature.hex
@echo 'Create Flash image (ihex format)'
-avr-objcopy -R .eeprom -R .fuse -R .lock -R .signature -O ihex ds18b20_temperature.hex "ds18b20_temperature.hex"
@echo 'Finished building: $@'
@echo ' '

I believe the line that is

ds18b20_temperature.hex: ds18b20_temperature.hex

should be

ds18b20_temperature.hex: ds18b20_temperature.elf

The macro expansions above it are all blank, rather curious...

Also, my other builds have the following macro expansions filled in, these are actually before the above, somehow it seems right when I do it this way..?...

# Add inputs and outputs from these tool invocations to the build variables
LSS += \

FLASH_IMAGE += \

EEPROM_IMAGE += \

SIZEDUMMY += \

AVRDUDEDUMMY += \

# All Target

The all target above is the one starting the first console paste. I haven't seen anything on this, but I'm sure if I can do it, someone else can also.

Thanks again...

Jack

I'm using the AVR plugin (for the ATmega 328p micro controller.) Not really interested in the Arduino, although it's kind of fun to toy with via their interface. Never tried the Eclipse version, I need more than the Arduino software usually does.

I have added a post since your's was posted about the macro's not expanding properly, I think. I have other code that was modified from the Arduino and had it compile and load properly. I don't know why this one won't pass the proper extension when it calls avr-objcopy.

Thanks for the assistance.
