下载编译源文件mosquitto-auth-plug-0.1.3.tar.gz
tar解压，进入目录，修改config.mk文件
内容如下

修改地方注解：
GCC和G++的路径
CC =/home/forlinx/work/edgeOS/build/toolchain/gcc-linaro-11.2.1-2022.02-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc
CXX=/home/forlinx/work/edgeOS/build/toolchain/gcc-linaro-11.2.1-2022.02-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++
交叉编译的mosquitto-1.5.8源码路径
MOSQUITTO_SRC = /home/forlinx/work/tool/mosquitto/mosquitto-1.5.8
交叉编译openssl的输出路径
OPENSSLDIR = /home/forlinx/work/tool/openssl/out
openssl、mosquitto、hiredis的交叉编译的lib和includ路径
CFG_LDFLAGS = -L/home/forlinx/work/tool/openssl/out/lib -L/home/forlinx/work/tool/mosquitto/out/lib -L/home/forlinx/work/tool/hiredis/out/lib
CFG_CFLAGS = -I/home/forlinx/work/tool/openssl/out/include -I/home/forlinx/work/tool/mosquitto/out/include -I/home/forlinx/work/tool/hiredis/out/include
最后make，生成auth-plug.so
