About rpm (easy question)
 

I installed fc7 .But
#rpm -ivh --aid packagename.rpm
seems does not work.
It can not resolve the dependency automatically.How to deal with it?

Have you tried using yum instead?

yum install packagename

Yum sorts dependencies for you

Otherwise, install the rpm(s) for the required dependencies

billymayday is correct. Please use yum to install and resolve dependencies. At the least if for some reason it can not download the dependencies (which has happened to me before when installing a local rpm) then it will give you the package names which contain the dependencies.
