I cannot link readline and I cannot find the reason for this failure.
Any help, please!!??
This is the source code I am trying to use:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <readline/readline.h>
#include <readline/history.h>
int main()
   char * tralala;
   tralala = (char*) readline ("please >");
};     /*   main()   */
This is what "gcc try.c" returns:
/tmp/ccw45mkp.o: In function `main':
try.c:(.text+0x19): undefined reference to `readline'
collect2: ld returned 1 exit status

PLEASE NOTE: "/etc/ld.so.conf"  contains "/usr/lib" and  "/sbin/ldconfig" has been run several times.
             I also downloaded the most recent readline  version I could find, 6.2, installed it in
             my home dir and tried to link to it. Same failure.
             Never had a similar error before with any system or Unix flavor I have used. And this
             is my 12th year with Linux. And my first attempt to use readline.
This is what "ls -l  /usr/lib/libreadline*" returns:

-rw-r--r-- 1 root root 300124 Jul 12  2006 /usr/lib/libreadline.a
lrwxrwxrwx 1 root root     16 Jul 17  2011 /usr/lib/libreadline.so -> libreadline.so.5
lrwxrwxrwx 1 root root     18 Jul 17  2011 /usr/lib/libreadline.so.4 -> libreadline.so.4.3
-rwxr-xr-x 1 root root 192228 Jul 14  2006 /usr/lib/libreadline.so.4.3
lrwxrwxrwx 1 root root     18 Jul 17  2011 /usr/lib/libreadline.so.5 -> libreadline.so.5.1
-rwxr-xr-x 1 root root 210256 Jul 12  2006 /usr/lib/libreadline.so.5.1

This is what "uname -a" returns:
Linux localhost.localdomain 2.6.18-1.2798.fc6xen  \
#1 SMP Mon Oct 16 15:11:19 EDT 2006 i686 athlon i386 GNU/Linux

THIS MEANS, among other things: "Fedora 6" with the kernel "2.6.18".
This is what "gcc --version" returns:

Description :
The Readline library provides a set of functions that allow users to
edit command lines. Both Emacs and vi editing modes are available. The

lines, and for performing csh-like history expansion on previous

PLEASE NOTE: On July 17 2011 I made a mistake and I had to wipe out
             the disk and install the system anew. Having several
             disks make this a child's play.

This is what "tcsh --version" returns:

tcsh 6.14.00 (Astron) 2005-03-25 (i386-intel-linux) options wide,

PLEASE NOTE: I have been using the "C" shell for approx 25 years,
             used Unix back in the '80s.
             I also, changed to "bash" for a minute in an attempt
             to solve the problem. No success.
I have never used "gnome" only KDE, I do not know how to find
its version, I think it is KDE-3.4.
I hope I thought of everything that is or may be relevant. And now, where are the  trees that
prevent me to see the forest, please!!??  after  two days of trying to find and move the trees
aside to see the forest I am really ashamed.
Thank you!!
