### Application-specific constants

APP_NAME := util_pkt_logger

### Environment constants 

LGW_PATH := ../libloragw
CROSS_COMPILE :=

### External constant definitions
# must get library build option to know if mpsse must be linked or not

include $(LGW_PATH)/library.cfg

### Constant symbols

CC := $(CROSS_COMPILE)gcc
AR := $(CROSS_COMPILE)ar

CFLAGS=-O2 -Wall -Wextra -std=c99 -Iinc -I.

### Constants for LoRa concentrator HAL library
# List the library sub-modules that are used by the application

LGW_INC = $(LGW_PATH)/inc/config.h

### Linking options

ifeq ($(CFG_SPI),native)

else ifeq ($(CFG_SPI),ftdi)
  LIBS := -lloragw -lrt -lmpsse
endif

### General build targets

all: $(APP_NAME) global_conf.json

clean:
	rm -f obj/*.o
	rm -f $(APP_NAME)

### HAL library (do no force multiple library rebuild even with 'make -B')

### Sub-modules compilation

obj/parson.o: src/parson.c inc/parson.h
	$(CC) -c $(CFLAGS) $< -o $@

### Select the proper configuration JSON for the program

ifeq ($(CFG_BAND),eu868)
