Ok, I am trying to compile a program called Gwyddion, which uses GTK+, as well as GtkGLExt. I need to compile and install GtkGLExt, but it gives me this error when I run configure:

checking for GTK+ - version >= 2.0.0... no
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK+ is incorrectly installed.
configure: error: GTK+ 2.0 not found

Once this happened, I attempted to compile and install GTK+ 2.6.x. I was able to compile GLib and install it. But then I tried to compile Pango, and confgure gave me this error:

checking for GLIB - version >= 2.5.7... no
*** Could not run GLIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.
configure: error:
*** Glib 2.5.7 or better is required. The latest version of
*** Glib is always available from ftp://ftp.gtk.org/.

This is odd, because I just compiled and installed the latest version of GLIB! Is there some environment variables I need to set? How do I deal with old versions that may or may not be installed? I'm a Linux newbie, so this is all very confusing to me. I am using Fedora Core 3, and I have used Yum to update everything. Help!

Did you run ldconfig as root after make install? You probaby should, and make sure the directory where the libs got installed to is included in /etc/ld.so.conf.

What distrobution do you use? Chances are it'll have glib, gtk and pango packages for you already.

I'm using Fedora Core 3. I tried running 'ldconfig', to no avail. Is there some command line options I need? I don't know if the built-in packages for GTK would have worked, because I started screwing with GTK before I tried to compile my program. So I may have messed it up. I wouldn't mind trying to restore those original packages. I thought of doing 'yum remove gtk' or something, and then re-installing it. But that would also uninstall gimp, and everything else depending on it. Ooooof.

Not necesarily, I don't use Fedora but try yum --hlep at a console and see what you get. Surely there will be an option to force remove and leave everything else there. They won't work without GTK obviously but it won't be an issue since you'l just be reinstalling it straight away

this should get you going:

Hi there. Ok, so I typed in the wrong thing with yum and totally wiped out gtk as well as all dependencies. Whoops! So I decided to dump Fedora, and installed Mandrake 2005 instead. I then used urpmi to get all the gtk and gtkglext devel packages, and then everything compiled just fine! Go figure. Thanks for your help all.
