build\core.a: No such file or directory

[inseo-oh]

When I try scons ARDUINO_PORT=COM5 ARDUINO_BOARD=atmega328 ARDUINO_VER=1.0.1 ARDUINO_HOME=C:\Arduino upload

I get these messages;;; fnCompressCore(["build\core.a"], ["build\core\WInterrupts.o", "build\core\wiring .o", "build\core\wiring_analog.o", "build\core\wiring_digital.o", "build\core\wi ring_pulse.o", "build\core\wiring_shift.o", "build\core\CDC.o", "build\core\Hard wareSerial.o", "build\core\HID.o", "build\core\IPAddress.o", "build\core\new.o", "build\core\Print.o", "build\core\Stream.o", "build\core\Tone.o", "build\core\U SBCore.o", "build\core\WMath.o", "build\core\WString.o"]) C:\Arduino\hardware/tools/avr/bin\avr-gcc -mmcu=atmega328p -Os -Wl,--gc-sections -o sketch.elf build\sketch.o build\lib_00\LiquidCrystal\LiquidCrystal.o build\l ib_00\NS_LCD_01\NS_LCD.o build\core.a -lm avr-gcc: build\core.a: No such file or directory scons: *\ [sketch.elf] Error 1 scons: building terminated because of errors.

why build\core.a dosen't exists?

Have you installed the Arduino IDE? Is it located at "C:\Arduino"? If so, is it version 1.0.1?

[inseo-oh]

It was 1.0.5;;;; I will try it later... It also works on 1.0.5?

I'm on Ubuntu 13.10 and unfortunately get the same error with recent builds of Arscons. It happens with Arduino 1.0.1 and 1.0.5. It would appear that the entry on line 404 might be to blame

I tried on windows... but it failed because "build/core.a" not exists. But on my Raspberry Pi(OS: Raspbian).. It works well..(I tried on /dev/ttyS0)

HI! Just experienced the same. Installed scons, then changed AVR_HOME to /usr/bin. That solved a previous error message, however I am now stuck with this. scons: *\ [build/core.a] No such file or directory Can you please advise what to correct? I am using Arduino 1.0.5 @ ARCH Linux

[roylines]

I have the same issue. Installed on 64 arch, set AVR_HOME to /usr/bin, then I get: scons: *\ [build/core.a] No such file or directory

[MadnessASAP]

I had the same issue, resolved it by adding a trailing forward slash to AVR_HOME option, i.e. AVR_HOME="/usr/bin/" not AVR_HOME="/usr/bin".

In case anyone is still looking here: This problem was caused by commit bb20696. To go back to a working version you need to checkout v1.0.0 (ca36aee).

Not sure if this is still an issue (although I did get the same error just now), but I think the source of the problem is that SConstruct is unable to locate the arduino "ar" utility. I found I could correct it by replacing this line:

   run([AVR_BIN_PREFIX + 'ar', 'rcs', str(target[0]), file])

with this:

   run([AVR_BIN_PREFIX + 'avr/bin/avr-ar', 'rcs', str(target[0]), file])

+1 ^ great fix @furious-luke thanks
