Hi,
I'm having trouble installing glChess. I'm running RedHat 9, Gnome 2.2, and I've installed GTK+-2.2.1 and I want to install gtkglext. But everytime I try to install it, I get the following error:

checking for gtk+-2.0 >= 2.0.0 gdk-2.0 >= 2.0.0 pango >= 1.0.0 gmodule-2.0 >= 2.0.0 ... Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found

configure: error: Library requirements (gtk+-2.0 >= 2.0.0 gdk-2.0 >= 2.0.0 pango >= 1.0.0 gmodule-2.0 >= 2.0.0 ) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.

I've installed pkgconfig-0.14.0 with both "./configure" and "./configure --prefix=/usr/bin" and as you can see above, I still get the same error. Any suggestions? Do I need to set the PKG_CONFIG_PATH? Shouldn't GTK+-2.2.1 install in a dir that is already recognized? Thanks. --jeremy.

These two commands can help you debug you PKG_CONFIG_PATH problem.

You can find out what your PKG_CONFIG_PATH is set to with the following command:

echo $PKG_CONFIG_PATH

Then if all else fails you can set PKG_CONFIG_PATH with the following command:

export PKG_CONFIG_PATH=/where/it/should/really/be

Install the gnome development libraries from the package manager

All I get from echo $PKG_CONFIG_PATH is a blank line:
"
$echo PKG_CONIG_PATH

$
"
That's it. And I have installed the gnome development libraries from the RPM packages that came with Redhat 9, so they should be the newest anyway. I'll try the export PKG_CONFIG_PATH, but I'm not sure that's going to work since (and I'm assuming here) I've installed gtkmm without problems (which required GTK+-2.0. Anyway, thanks for the help. Oh and another question, I heard somewhere that RH9 uses a modified version of Gnome, does anyone know what these modifications involved? Thanks.

Are you sure you have the gnome development libs? If so, you should have some files in /usr/lib/pkgconfig

RH9 do some custom artwork on both KDE and GNOME, and alter the default desktop layout of GNOME to be more like Windows/KDE (kde can't do the gnome default, not flexible enough, but RH want them both the same so gnome has to change).

When you do an install your distribution sets up PKG_CONFIG_PATH. I don't think that it is done by any of the development packages when they install. The last time I installed SuSE I did not install the Gnome development group of packages so SuSE did not set up PKG_CONFIG_PATH for me. Later when I installed the Gnome development packages by hand I had to set PKG_CONFIG_PATH by placing the following command in /etc/profile.local

export PKG_CONFIG_PATH=/usr/lib/pkgconfig

Since your PKG_CONFIG_PATH is blank I think that you need to do something similar depending on where your distribution places global export commands.
