1、git clone https://github.com/StefanoDeVuono/steghide.git
2、autoreconf -i
3、./configure
4、make
编译完成后再src目录下又steghide执行下程序
报错：configure: error: cannot find required auxiliary files: compile时需要执行autoreconf
如果往jpg文件里写入是提示没有支持libjpeg，则先安装libjpeg-dev libjpeg8-dev，debian系统上使用sudo apt install libjpeg-dev libjpeg8-dev,再执行./configure后make
