Where is the PKG_CONFIG_PATH environment variable?

Where is the PKG_CONFIG_PATH environment variable and what is the proper proceedure to set it?

What does this variable do for package config program (pkg-config)?

How does pkg-config work?

I am getting all kinds of error trying to install gtk+ and its underlying compnents to get Xwindows to work again. I think I need to under stand pkg-config better because some of the components wont install saying pkg-config cannot find dependencies.

pkg-config looks for .pc files telling it where other packages are installed.
eache directory is separated by a :
if installing gnome in prefix=/usr/gnome2 you whould add
:/usr/gnome2/lib/pkgconfig, to the example below

If you are using Mandrake or redhat you can set it in /etc/profile by adding these two lines:

PKG_CONFIG_PATH=/usr/lib/pkgconfig
export PKG_CONFIG_PATH

just run

export PKG_CONFIG_PATH=whatever

from the command line before running configure.

However, your system must be pretty broke if you need to install GTK. Red Hat comes with it as standard.

So is PKG_CONFIG_PATH the path where pkg-config is installed or where the .pc files are installed?

Hence the name PKG_CONFIG_PATH, the "path" to "package config"
