Well heres my first post on linuxQuestions. I use debian and build the gui with xfce. I just got my laptop up running solely debian a few days ago. I remeber my last linux box i was able to use the tutorial at:

tinyminds.org/modules.php?op=modload&name=Sections&file=index&req=viewarticle&artid=39&page=1

to build gmplayer with all the right codecs (wma, reel player, quicktime, divix, and so on and so forth, but this is out of date now. I try to follow it as closely as i can, but when i do the ./configure --enable-gui, i get the error "Error: X11 Support required for gui compilation". How do i go about getting x11 support? Is there a more up to date tutorial out there that i cant find? Any good tutorials on the codecs i might need?

Thanks for your help

X11 is your actual GUI, which you very likely have (unless you're in a terminal...). Try installing the X11 development libraries. If that doesn't work, you don't actually enable any GUI support in MPlayer when you do ./configure (as far as I know). All it does is create a symlink to mplayer called gmplayer, which runs. If you compile mplayer without the GUI. but create a symlink to the binary called gmplayer and run it, you will get the GUI.

Hi you're welcome to try mine. I'm guessing all you need is the X11-devel packages (or xorg-devel). And probably gtk-devel also.

As I understand mplayer will NOT run the gui unless the --enable-gui flag was compiled into it.
