Can anyone help me with this error?
I've been trying to install devhelp for Anjuta. I cd'd to the source directory
and typed in ./configure. Lots of messages get printed to the screen then I get
this error:

Checking for pkg-config.
Could not run GLIB program.
GLIB may not be correctly installed.
Package gtk+-2.0 not found.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable.

First, my PKG_CONFIG_PATH was empty. I don't have any file called
'gtk+-2.0.pc', but I do have one called 'gtk+.pc' in 'usr/lib/pkgconfig/'. I set
PKG_CONFIG_PATH="usr/lib/pkgconfig" and renamed 'gtk+.pc' to 'gtk+-2.0.pc', but
it still gave the same error. I checked to see if I had the gtk+ package and
found that "The package 'gtk+2.-2.0.6-8mdk' is installed".

How can I get past this error?

look at your config.log and check for the bit where it trys to run the glib program. It looks like it gets past pkg-config and trys to compile & run a glib program which doesn't work for whatever reason.

I think this is the relevent part of config.log.
There is a check for 'GLIB - version >= 2.0.0' with 'result: no'. So I checked my packages and found I had 'glibc-devel-2.2.5-16mdk'. Does that mean that my glib version is 2.2.5? If so, then why did I get a fail result? Am I short of a path to the glib library? Any other comments? I'm not too sure how to use this config.log info.

"glib" is different from "glibc"

look for glib-devel

>>"glib" is different from "glibc"
Is that why it's not working?

The 'glib' packages I have installed are;
glibc-devel-2.2.5-16mdk
glibc-i18ndata-2.2.5-16mdk
libglib1.2-devel-1.2.10-16mdk

The packages I can install are;
glib-gettextize-2.0.6-2mdk
glibc-doc-2.2.5-16mdk
glibc-doc-pdf-2.2.5-16mdk
glibc-static-devel-2.2.5-16mdk
glibc-utils-2.2.5-16mdk
libglib2.0_0-devel-2.0.6-2mdk
libglibwww1-0.2-3mdk
libglibwww1-devel-0.2-3mdk

I don't have any glib-devel packages though. What do I install?

Ive just downloaded 'glib-1.2.10-8.src.rpm'. Should I install that? What switches/options should I use?

it's checking for...
configure:7726: checking for GLIB - version >= 2.0.0

so install these 2...

glib-gettextize-2.0.6-2mdk
libglib2.0_0-devel-2.0.6-2mdk

I installed them both. libglib2.0***** needed 'pkgconfig-0.12.0-2mdk' as a dependency and had to be installed first. However, after installing the packages, plus dependency, I ran ./configure again, but I got the exact same error messages at the exact same point!
Should I install something else? I don't need to reboot do I?

if in your config.log, if you see that it can't find glib.h again, search for glib.h, rpm -q -l libglib2.0-devel
./configure --help may give you some options to tell it where to look for glib include files and set it to where you found the glib.h or there may even be a --disable-glib-test option.

basically you got to be able to compile a simple glib program to get rid of the message.

Sorry, I missed off a bit in my earlier post - glib compiled, thanks - I simply didn't notice it - but I was still getting gtk+ error messages. Here is the same part of config.log.

Now the configure script is lookling for a file called gtk+-2.0.pc (see my first post). But I don't have that file. I have gtk+.pc only. I renamed gtk+.pc to gtk+-2.0.pc and set PKG_CONFIG_PATH to point to it, but still the same error (can't find gtk+-2.0 package) came up.

look for a package similar to... gtk+2-devel.-2.0.6-8mdk

don't rename gtk+.pc, that's the pkgconfig for gtk1 I think.
