How to install RealPlayer

For more information, see how to install RealPlayer-general Linux technology-Linux technology and application. I really don't know what to do! This is the process of installing Realplayer. Thank you for your advice!

1. I downloaded RealPlayer 11 for linux rpm (RealPlayer11GOLD. rpm) from the Internet)

2. After running the installation command, the system prompts:
Lsb> = 3.1 is needed by RealPlayer-11.0.0.4028-20080225.i586

3 good! I got an rpm package online: redhat-lsb-3.1-14.fc7.i386.rpm
Run the following command to install: # rpm-U redhat-lsb-3.1-14.fc7.i386.rpm
Error: Failed dependecies:
Libstdc ++. so.6 is needed by redhat-lsb-3.1-14.fc7

4, okay! I downloaded libstdc ++ 6-4.1.1-3mdk.i586.rpm from the rpmfind.net website.
Also prompts me to install gcc3.3;

5 no way, and can only download gcc, version for gcc3.3-debug-3.3.6-3mdk.i586.rpm,
Install gcc3.3. I was so happy that I was able to handle it. But go back and install libstdc ++
The system prompts me that gcc3.3 needs to be installed .???
I had to re-run the gcc installation command again. The strange thing is that the system prompts:
Package gcc3.3-The debug-3.3.6-3mdk.i586.rpm is already installed.
Dizzy! I really don't know why!

Supplement: The redhat installation is required by the lab. 9.
The younger brother checked the information online for a long time, so he had to bother everyone.
The younger brother, of course, not only wants to install this player, but also wants to learn a little bit about linux
The essence!
