Debian系统apt-get build-dep命令
apt-get build-dep 包名,这条命令用于在编译安装软件时,自动安装相关的编译环境。比如我要编译nginx,当然可以从网上找到需安装哪些库,用apt-get install XXXX XXXX XXXX ... 来进行安装。但是有时候装了一堆库,可能有几个是用不到的。而是用apt-get build-dep命令可以更好的管理这些库文件和编译环境。
先更新软件源列表:
apt-get update
以编译nginx为例,安装所需的编译环境:
apt-get build-dep nginx

由于关系包有很多,如果想卸载可以在安装前先记录下build-dep安装的包:
apt-get build-dep nginx | tee nginx-build-dep.txt
Debian系统可以用Deborphan清理没有被依赖的软件包:
apt-get install deborphan
查找没有被依赖的软件包:
deborphan -sPz
删除找到的包:
apt-get autoremove `deborphan`
