(On Ubuntu Hardy, but I don't see any reason why this would make a difference.)

After following all of those instructions precisely, when I attempt to configure Gimp's makefile, it tells me that I need gegl, even though I already have gegl installed.

Here's the output of the configure script:

configure: error: Test for GEGL failed. Please get it from http://gegl.org/

Before anyone complains, I did check that topic, and grepping couldn't help me. Or, at least, I had no idea what I was supossed to do with the results that it returned.

Help?

There are several possibilities:

* Did you install Gegl yourself and forgot to call "ldconfig" afterwards?

* Did you install Gegl somewhere strange? Than add the path where gegl.pc (the pkgconfig file) is put into to PKG_CONFIG_PATH and run configure again.

1. Huh? Forgive me for being a newbie, but I can't seem to locate the file "ldconfig" anywhere, nor did I ever read of any mention of it anywhere in any of the guides I read, mind explaining that in greater detail? That may be the problem then.

2. gegl.pc is in /opt/gimp-2.5/lib/pkgconfig, is it supposed to be somewhere else?

"ldconfig" is a program which is called after you installed new libaries - it updates an important library cache so to speak.

Yes, your Gegl is in a strange place and this is what's happening:

* You call "configure".
* Configure checks wether or not libs 'n' stuff is available
* Configure calls a tool called "pkgconfig" for that
* Pkgconfig checks in certain places for its files - in your case "gegl.pc"

Now it fails, because the standard path where pkgconfig looks for pc files is in /usr/lib/pkgconfig - you'll have to add EVERY other place by hand.

Cut and paste this:

export PKG_CONFIG_PATH=/opt/gimp-2.5/lib/pkgconfig:$PKG_CONFIG_PATH

and re-do configure.

I _think_ you probably have called gegl's configure also with --prefix=/opt/gimp2.5 and that's why gegl throw its stuff and libs and pkconfig files into this directory.

Another typical place for pkgconfig pc files is in /usr/local/lib/pkgconfig, so to be on the safe side, you better also add this directory to PKG_CONFIG_PATH:

export PKG_CONFIG_PATH=/opt/gimp-2.5/lib/pkgconfig:/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

That did it. ty
