(libraries) Installing gtk, help please

[Arturo Tena <arturotena linuxccm ccm itesm mx>]

Hello !!

I have accessed
http://www.redhat.com/linux-info/gtk/gtk-list/
to search for the answer, but the search link is broken =(

Although I considering me such as a beginner in the Linux world, may be
you wish to help me, please.

I've just downloaded gtk...
1) I run configure...... all OK
2) I run make........... all OK
3) I run make install... all OK expect for the next message appeared
some times:

...
chmod 644 /usr/local/lib/libgdk.a
PATH="/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/bin/mh:/home/arturo/bin:/sbin"
ldconfig -n /usr/local/lib
------------------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

To link against installed libraries in a given directory, LIBDIR,
you must use the `-LLIBDIR' flag during linking.

 You will also need to do one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
------------------------------------------------------------------------------
/bin/sh ../mkinstalldirs /usr/local/bin
/bin/sh ../mkinstalldirs /usr/local/include/gdk
...
...

OK, let's add /usr/local/lib to /etc/ld.so.conf

4) Tried to compile hello.c example (from Info pages):

[arturo@localhost gtk]$ cat /etc/ld.so.conf
/usr/i486-linuxaout/lib
/usr/X11R6/lib
/usr/i486-linux-libc5/lib
/usr/local/lib
[arturo@localhost gtk]$ su
Password: 
[root@localhost gtk]# /sbin/ldconfig
[root@localhost gtk]# exit
[arturo@localhost gtk]$ gcc hello.c -o hello

[arturo@localhost gtk]$ 


What's missing?


NOTE: I know gcc can't find gtk lib, why? If I run:

[arturo@localhost gtk]$ gcc hello.c -o hello -L/usr/local/lib
-L/usr/X11R6/lib -lgtk -lgdk -lglib -lXext -lX11 -lm

or

[arturo@localhost gtk]$ gcc hello.c -o hello -L/usr/X11R6/lib -lgtk
-lgdk -lglib -lXext -lX11 -lm

'hello' runs pretty well, but if i run:

[arturo@localhost gtk]$ gcc hello.c -o hello -L/usr/X11R6/lib -lgdk
-lglib -lXext -lX11 -lm

the error message:

/tmp/cca280621.o: In function `main':
/tmp/cca280621.o(.text+0xf): undefined reference to `gtk_init'
/tmp/cca280621.o(.text+0x19): undefined reference to `gtk_window_new'
/tmp/cca280621.o(.text+0x28): undefined reference to
`gtk_container_get_type'
and so on...

appears again.


Please, help me...

THANK YOU IN ADVANCE for your time and your answer !! =) =)
