Arduino.mk insists on building way too many unnecessary libraries

kenrestivo opened this issue 12 years ago · 7 comments

I have this simple makefile

ARDUINO_DIR   = /usr/share/arduino
ARDMK_DIR     = /home/localkens/embed/src/Arduino-Makefile
AVR_TOOLS_DIR = /usr

BOARD_TAG    = diecimila
ARDUINO_PORT = /dev/ttyUSB4

ARDUINO_LIBS= SoftwareSerial

ARDUINO_USER_LIBS = ModbusMaster

USER_LIB_PATH=../../../

include /home/localkens/embed/src/Arduino-Makefile/arduino-mk/Arduino.mk

And make seems to insist on building all kinds of insane stuff, like HID and USB, and IPAddress???!, when I did not tell it to do that.

/usr/bin/avr-gcc -c -mmcu=atmega168 -DF_CPU=16000000L -DARDUINO=100 -I. -I/usr/share/arduino/hardware/arduino/cores/arduino -I/usr/share/arduino/hardware/arduino/variants/standard -I/usr/share/arduino/libraries/SoftwareSerial -I../../..//ModbusMaster -g -Os -w -Wall -DUSB_VID= -DUSB_PID= -ffunction-sections -fdata-sections -std=gnu99 ../../..//ModbusMaster/ModbusMaster.cpp -o build-diecimila/libs/ModbusMaster/ModbusMaster.o
/usr/bin/avr-ar rcs build-diecimila/libcore.a  build-diecimila/WInterrupts.o  build-diecimila/wiring_analog.o  build-diecimila/wiring.o  build-diecimila/wiring_digital.o  build-diecimila/wiring_pulse.o  build-diecimila/wiring_shift.o  build-diecimila/CDC.o  build-diecimila/HardwareSerial.o  build-diecimila/HID.o  build-diecimila/IPAddress.o  build-diecimila/main.o  build-diecimila/new.o  build-diecimila/Print.o  build-diecimila/Stream.o  build-diecimila/Tone.o  build-diecimila/USBCore.o  build-diecimila/WMath.o  build-diecimila/WString.o  build-diecimila/libs/SoftwareSerial/SoftwareSerial.o build-diecimila/libs/ModbusMaster/ModbusMaster.o 
/usr/bin/avr-gcc -mmcu=atmega168 -Wl,--gc-sections -Os -o build-diecimila/Basic.elf build-diecimila/Basic.o build-diecimila/libcore.a  -lc -lm
/usr/bin/avr-objcopy -O ihex -R .eeprom build-diecimila/Basic.elf build-diecimila/Basic.hex

Why does it think that a diecimilla is a Leonardo? It isn't. I've been looking around in the makefile to try to find out where this mistake is coming from, and can't seem to find it anywhere.

Answer 1 · 2012-12-05T11:53:35.000Z

Hmm, I see. It's just grabbing everything in ARDUINO_CORE_PATH, and not making any decisions as to which core files make any sense for the target device.

Answer 2 · 2013-02-22T17:50:08.000Z

It's doing the same thing to me, building all of the core libraries.

Answer 3 · 2013-06-14T18:09:12.000Z

yup, i just noticed this too - Stream, WMath, Tone, HardwareSerial, USBCore etc.even for Blink.

they're not getting put into the hex though (800k of libs, 4k hex!) so its just a waste of compile time rather than arduino memory.

Answer 4 · 2013-06-15T01:50:00.000Z

I just enabled verbose logs in Arduino IDE to see how Arduino handles it. It seems even Arduino IDE tries to compile everything, but link only the necessary stuff as @sej7278 found out.

I am thinking of marking it as wontfix. What do you guys think?

Here is the (rather long) output from Arduino IDE

I noticed that, forgot to update the issue, sorry. It is irritating but not a huge problem; as the linker filters all that stuff out. Your call if you want to keep it open or not.

Answer 6 · 2013-06-15T03:46:55.000Z

I am marking this issue as enhancement and not closing it.

The fix for this issue will be "nice to have", and that's why I am not marking it as wontfix.

Would be happy to merge, if someone can implement it. But I am not sure, if it can be implemented.

yeah thats fine as the IDE does it that way too, also upon a 2nd pass of make it doesn't rebuild everything
