Everyone is raving about how cool mplayer is so I thought Id give it a try, I use xine now with a gtk-based media player style gui so I have compiled using gtk...

When I try to "./configure --enable-gui" mplayer I get an error that states:

config log states:
Also, Im running Fedora 2 and checked the install and I DO have gtk2-devel installed...

Can someone help me out?

Thanks,
Chris

Wild guess:

gtk != gtk2

do you have gtk2-devel in the default directories?

If not, you may want to tell the config where they are. I can't remember exactly how but there's a way. If you do, you may want to try to tell it anyways. Couldn't hurt.

I think it's ./configure --libdir=/path/to/gtk2/libs
or something like that.

all else fails, ./configure --help and try try again.
good luck

Yeah, I have gtk & gtk-2.0 directories installed by the system discs when I built the machine in /usr/lib

I guess thats the default place..

-edit-
I guess /usr/lib is incorrect.
After looking through the directories it seems as though the only thing in those dirs is some RedHat specific stuff...

Can anyone tell me where gtk and glib are usually installed?

It's in /usr/lib
in slack ... if you compiled from source, and didn't change
the prefix, it's in /usr/local/lib
If you installed from rpm, use rpm -q<x> to find out where
they are ...
Or a
locate libgtk

Tinkster nailed it.

Well... I got it to work... I guess by default, Fedora2/KDE does not come with GLIB or GTK installed.

I had to install GLIB 1.2 first then GTK 1.2 from source ( http://www.gtk.org/download/ ) ...
after that, "./configure --enable-gui" worked fine.. make & make install went ok and im now watching a video from command line...

Now for thr GUI!

Thanks for your help!

That's how to solve this troubleshooting "Can't find GTK devel" from mplayer.

Error message is
You can't find gtk-config on your system [locate gtk-config will help to check this]

Then you have to urpmi *libgtk+1.2-devel*

Therefore mplayer will compile without complaining about "Can't find GTK devel"

Hope this helps.

Well, I've spent a couple of hours fooling around with mplayer and I finally got it to work. Since I ran into the same issues, I thought I'd write how I made it work, maybe that helps someone.

I use Suse 10.0 Evaluation and this mplayer file "MPlayer v1.0pre7try2 source":
The first step consists in deinstalling the gtk and gtklib which are too recent, for instance via the "Software management" tool in Yast. This will solve the "GTK devel" problem.
Then download a few rpms or the source, whatever you like and install them onto your system. For me, following files worked perfectly:
a)glib-1.2.10-586.i586.rpm
b)glib-devel-1.2.10-595.i586.rpm
c)gtk-devel-1.2.10.885.i586.rpm

That solved the problem I was having while running configure with disabled gcc version check, that is the "GTK devel needed" problem.

Now to the gcc version issue:
At first, I tried to configure mplayer with the "--disable-gcc-checking" option because I figured out that my version of gcc would do and I wasn't thrilled at the thought of downgrading a working program. Well, I was wrong and ran into problems with the compilation of the libacodecs during make. To make a long story short, take the warning concerning the required version of gcc seriously.
So deinstall your gcc, libgcc and cpp using, for instance, the "software management" tool in Yast. Then install the museum version, for me, following files worked perfectly:
a)cpp-3.3.3-1.i586.rpm
b)libgcc-3.3.3-1.i586.rpm
c)gcc-3.3.3-1.i586.rpm

After installing all these files in this version, I had no problem whatsoever configuring and making mplayer with gui support.

Hope this helps anyone. Oh, and you still can reupdate gtk and gcc when you're done compiling mplayer.
