missing wiring_pulse.S from compilation

[thinkberg]

MacOS X 10.10.4
avr stuff via homebrew
Arduino IDE 1.6.5

I have tried to compile a sketch which uses pulseIn(). This in turn uses a function from wiring_pulse.S that is not linked/compiled for some reason. The Arduino IDE 1.6.5 compiles it

sources can be found here

Arduino IDE build process:

/Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin/avr-gcc -c -g -x assembler-with-cpp -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=10605 -DARDUINO_AVR_UNO -DARDUINO_ARCH_AVR -I/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/cores/arduino -I/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/variants/standard /Applications/Arduino.app/Contents/Java/hardware/arduino/avr/cores/arduino/wiring_pulse.S -o /var/folders/c5/9sqmvxp54m3cmjb6hmtw2xlm0000gn/T/build5848034434382423610.tmp/wiring_pulse.S.o 

what my make produces (countPulseASM is in wiring_pulse.S which is not mentioned during the build process):

/Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin/avr-gcc -mmcu=atmega328p -Wl,--gc-sections -Os -o build-uno/hc-sr04-led.elf build-uno/hc-sr04-led.o build-uno/libcore.a  -lc -lm
build-uno/libcore.a(wiring_pulse.o): In function `pulseIn':
wiring_pulse.c:(.text.pulseIn+0x32): undefined reference to `countPulseASM'
collect2: error: ld returned 1 exit status
make: *** [build-uno/hc-sr04-led.elf] Error 1

My makefile:

# http://hardwarefun.com/tutorials/compiling-arduino-sketches-using-makefile

#BOARD_TAG=uno
ARDUINO_PORT=/dev/cu.SLAB_USBtoUART

include /usr/local/opt/arduino-mk/Arduino.mk

From a quick look, the arduino-makefile looks at all the source types, maybe it misses on wiring_pulse because it exists as wiring_pulse.c and wiring_pulse.S?

[sej7278]

we need the full output from "make" so we can see your settings, for example is arduino-mk even finding your arduino 1.6.5 installation?

you need to specify a BOARD_TAG (uncomment it) in your Makefile or it won't do anything at all.

edit: it certainly builds on 1.0.5 for linux (with BOARD_TAG=uno uncommented) just downloading 1.6.5 now

edit 2: yes hc-sr04-led.ino doesn't seem to link properly on 1.6.5

[thinkberg]

I didn't change the BOARD_TAG in the end as it was auto-detected as uno (or default).

[sej7278]

i'm not sure, i've got a feeling they made some changes to pulsein in 1.6.5, maybe try 1.6.4 or somesuch?

edit: yes in 1.6.5 they added an assembler version pulseInASM() which seems to be broken, 1.6.4 works fine as it doesn't even have the .S file

https://github.com/arduino/Arduino/commits/master/hardware/arduino/avr/cores/arduino/wiring_pulse.S

[thinkberg]

just tested as well, yes 1.6.4 works.

[sej7278]

i can't figure out why the .S file is being ignored by our Makefile, I thought it might be that we were only building .S files in libraries not the core, but this makes no difference:

i guess its a problem with wiring_pulse.c and wiring_pulse.S becoming the same object file wiring_pulse.o

[peplin]

i guess its a problem with wiring_pulse.c and wiring_pulse.S becoming the same object file wiring_pulse.o

I ran into that problem back in #255 so it's quite possible that's also the root cause here.

[ladislas]

May be we should reconsider merging #266?

[sej7278]

I've (manually!) rebased and edited bits of @peplin's PR #266 and #256 into PR #365

This seems to fix @thinkberg's issue with wiring_pulse.S on IDE 1.6.5 and allows us to use chipKIT mpide-0023-linux64-20140821 which had a similar problem (issue #255)

[thinkberg]

Awesome, thanks!

[tschannerl]

Hi, exactily, I change version 1.6.9 to 1.6.4 and working fine.... Worse than in new version 1.8.1 is with the same problem.....

[chrisspen]

Why was this closed? I'm still getting this error with Arduino 1.8.1 and the current 1.5 release of Arduino-Makefile. Is there a workaround?

[mdasyg]

I am still getting the error on Arduino 1.8.7 . I made a temporary fix:

Append the following lines to the file /opt/arduino/hardware/arduino/avr/cores/arduino/wiring_pulse.c

      while ((*port & bit) == stateMask) {
          if (++width == maxloops)
              return 0;
      }
      return width;
 }

With this snipset of code I was able to compile my Nanpy firmware with 1.8.7 on Linux AMD64 via command line (arduino-mk) and resolved the problem of undefined reference to `countPulseASM'.

Hope that this helps you.
