i'm trying to compile the code of a program(Gaim), since there are no newer rpms for SuSE 9.2 (i never compiled a program before). When i do ./configure it shows me:

...
...
checking for GLIB - version >= 2.0.0... 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 2.0 is required to build Gaim; please make sure you have the GLib
*** development headers installed. The latest version of GLib is
*** always available at .....(gtk url)

I have GLIB 2.4.6-5 installed and i also installed GLIB
2.4.7.

How do i compile this?

You need to have the development headers installed, for SuSE I believe these are named using a -devel suffix. So for glib you need to install the glib-devel package. There are other development packages that will be required as well...
