problem with installing GTK+

[vineeta7]

Hi I am trying to install GTK+2.8. for that i have installed GTK+2.8 package from site.
I have installed Glib2.8.6 and pango 1.10.4 properly/
Bur when I run configure command for atk1.10.3 library.. I am getting this error

*** 'pkg-config --modversion glib-2.0' returned 2.8.6, but GLIB (2.2.1)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
*** If pkg-config was wrong, set the environment variable PKG_CONFIG_PATH
*** to point to the correct configuration files
no

And you ran ldconfig as suggested?

[vineeta7]

hi

I havent run that ldconfig.where it is located?

[Dapper Dan]

From the command line as su, run:

/sbin/ldconfig

or,

ldconfig

...whichever works and press enter. Not saying this is your problem, but as the errors suggest, it would be the first thing I'd do...

Which distro are you using and why do you need gtk+2.8?
