安装完minigui1.6.8出现问题，请高手指点

1. 从网站上下载了minigui-dev-1.6.8-linux.i386.rpm，然后安装
   rpm -ivh minigui-dev-1.6.8-linux.i386.rpm

2. 编译edit.c文件，gcc -o edit edit.c -lminigui -lpthread -lpng -ljpeg
   发现找不到库png和jpeg

3. 安装png库，从http://www.libpng.org/pub/png/libpng.html下载libpng1-1.2.8.tar.gz和zlib-1.2.3.tar.gz并解压到libpng和zlib中，
   先安装zlib，
   ./configure
   make
   make install
   再安装png
   cp script/makefile.linux makefile
   make
   make install

4. 重新编译edit.c, gcc -o edit edit.c -lminigui -lpthread -lpng -ljpeg
   出现错误

自己分析了一下，libpng.so里面的undefined reference 好像都是引用zlib中的东东，
libminigui.so不知道引用了什么库里面的东东有问题

请高手指点

自己来回答吧，在编译libpng时，需要加上-lz,-lm两个库，现在可以成功编译过去了
