Hi, I am fairly new to linux. I am trying to install Mplayer with the GUI. I use the following command
./configure --enable-gui

After it starts compiling, it quits and gives me the following error

Error: PNG support required for GUI compilation, please install libpng and libpng-dev packages.

So I went and downloaded the libpng and libpng-dev files and thought that I had installed them successfully. I used the make, and the make install command. It seemed like they installed successfully.
I do have a theory as to why this is still giving me this error. I really don't understand the whole concept of installing programs yet, I was logged in as my regular user account and used the "su" command through a terminal to run the make, and make install commands within the /home/scrob/libpng directory, which is where I extracted the tar file too. Do I need to log in as root in order for the make install command extract to the correct directories? Could someone please explain some basics when it comes to installing these two packages? Thank you so much!!

Hi,
In order for someone to help you, you need to be more precise..
First, which distro are you using ?
If it's Mandrake, then, I could be of some help because I've got Mplayer running well.
Cheers !

I have Redhat 9 running. Any thoughts?
