0.交叉编译工具安装和卸载
sudo apt-get install gcc-arm-linux-gnueabihf
sudo apt-get install g++-arm-linux-gnueabihf
sudo apt-get remove gcc-arm-linux-gnueabihf
sudo apt-get remove g++-arm-linux-gnueabihf
 
1.libuuid编译
https://sourceforge.net/projects/libuuid/
tar xzvf libuuid-1.0.3.tar.gz
cd libuuid-1.0.3/
 ./configure CC=/usr/bin/arm-linux-gnueabihf-gcc --host=arm-linux --prefix=/home/name/arm/lib/libuuid/
make
make install
拷贝相关的lib和include
在lib和include目录

2.openssl编译
wget https://www.openssl.org/source/old/1.0.2/openssl-1.0.2e.tar.gz
tar -zxvf openssl-1.0.2e.tar.gz
./config  no-asm -shared --prefix=/home/name/arm/lib/libopenssl
rm -m64 from Makefile
将其修改为CC=arm-linux-gnueabihf-gcc(你自己所用到的交叉编译器)
将SHLIB_VERSION_NUMBER=1.0.0改为1.0.2
将SHLIB_MINOR=0.0修改为0.2，保存退出
make
make install
拷贝相关的lib和include
在lib和include目录

3.交叉编译libmosquitto及mosquitto
wget https://mosquitto.org/files/source/mosquitto-1.5.5.tar.gz
tar -zxvf   mosquitto-1.5.5.tar.gz
新建目录dependon把前面的include和lib放进去
修改config.mk
添加
CROSS_COMPILE=arm-linux-gnueabihf-
CC=gcc -I../dependon/include  -L../dependon/lib -lssl -lcrypto -luuid
CXX=g++
最后
make
修改prefix?=/usr/local为 prefix?=/home/name/arm/mosquitto
make install
