No source file info in elf file #679

Copy link

When built with DEBUG defined, the generated elf file does not contain source file info, as verified with avr-objdump -S ..., at least with the AVR Mega328P target. This makes debugging using the elf file restricted to assembly only.

This is because the linker is not supplied with the -g flag. A fix could be as simple as adding -g to LDFLAGS if DEBUG is defined, but I'm not sure of the consequences for other targets.

Arduino.mk Configuration:

  • [AUTODETECTED] CURRENT_OS = LINUX
  • [AUTODETECTED] ARDUINO_DIR = /usr/share/arduino
  • [AUTODETECTED] PYTHON_CMD = /usr/bin/python3
  • [USER] ARDMK_DIR = /home/tomh/git/pico/ropemaker/fw/Arduino-Makefile

  • [COMPUTED] ARDMK_VERSION = 1.6
  • [COMPUTED] CC_VERSION = 5.4.0 (avr-gcc)

Makefile:

Want latest version so use submodule from git.

ARDMK_DIR := $(realpath ../Arduino-Makefile)

BOARD_TAG = nano
BOARD_SUB = atmega328old

The makefile gets this wrong.

AVRDUDE_CONF = /etc/avrdude.conf

MONITOR_PORT = /dev/ttyUSB1

ISP_PROG = atmelice_isp

CXXFLAGS += -Wextra -Wno-unused-parameter -Wno-pragmas -Wshadow -Wdouble-promotion -fno-common -funsigned-char -funsigned-bitfields
CXXFLAGS += -fpack-struct -fshort-enums -Wundef

Debug switch, if not defined DEBUG_FLAGS ignored and optimisation set to 's'.

DEBUG = 1
DEBUG_FLAGS = -DDEBUG -g3 -Og

include $(ARDMK_DIR)/Arduino.mk
