编译运行

环境配置:

// 我们人脸识别开门模块调用了阿里云的sdk,请确保arm设上已经安装了对应SDK,和阿里云服务配置,请去这里安装指示配置(按照指示下载SDK,添加阿里云AccessKey)

人脸识别_身份验证识别_客流分析系统_人脸门禁闸机-阿里云 (aliyun.com)

编译

由于文件众多,我们采用Makefile,来编译

Makefile

cpp 复制代码
CC := aarch64-linux-gnu-gcc

SRC := $(shell find src -name "*.c")

INC :=  ./inc \
		./3rd/usr/local/include \
		./3rd/usr/include \
		./3rd/usr/include/python3.10 \
		./3rd/usr/include/aarch64-linux-gnu/python3.10 \
		./3rd/usr/include/aarch64-linux-gnu

OBJ := $(subst src/,obj/,$(SRC:.c=.o))

TARGET=obj/smarthome

CFLAGS := $(foreach item, $(INC),-I$(item)) # -I./inc -I./3rd/usr/local/include

LIBS_PATH := ./3rd/usr/local/lib \
		 ./3rd/lib/aarch64-linux-gnu \
		 ./3rd/usr/lib/aarch64-linux-gnu \
		 ./3rd/usr/lib/python3.10 \
#L
LDFLAGS := $(foreach item, $(LIBS_PATH),-L$(item)) # -L./3rd/usr/local/libs

LIBS := -lwiringPi -lpython3.10 -pthread -lexpat -lz -lcrypt

obj/%.o:src/%.c
	mkdir -p obj
	$(CC) -o $@ -c $< $(CFLAGS)

$(TARGET) :$(OBJ)
	$(CC) -o $@ $^ $(CFLAGS) $(LDFLAGS) $(LIBS)
	scp obj/smarthome ini/gdevice.ini orangepi@192.168.1.18:/home/orangepi


compile : $(TARGET)

clean:
	rm $(TARGET) obj $(OBJ) -rf
debug:
	echo $(CC)
	echo $(SRC)
	echo $(INC)
	echo $(OBJ)
	echo $(TARGET)
	echo $(CFLAGS)
	echo $(LDFLAGS)
	echo $(LIBS)



.PHONY: clean compile debug

可以看到我的Makefile 里面添加了scp传送,请根据自己的派的ip进行修改

运行:

sudo -E ./smarthome

sudo -- 因为我们调用了wiringpi库来调节电平,需要访问到系统文件

-E 保持环境,即我们可以使用root用户里面配置的AccessKey,来访问阿里云的接口
