Configure fails to find readline libraries

I'm attempting to install 8.2x postgresql, and configure fails to find the
realine libraries.
Here's my configure:

./configure --with-includes=/usr/local/include:/usr/local/include/readline
--with-libraries=/usr/local/lib

Before running configure, try

export CFLAGS="-I/usr/local/include -I/usr/local/include/readline"
export LDFLAGS="-L/usr/local/lib"

Thanks, but that didn't work. Here's the complete error result from
that:

checking for -lreadline... no
checking for -ledit... no
configure: error: readline library not found
If you have readline already installed, see config.log for details on
the
failure. It is possible the compiler isn't looking in the proper
directory.
Use --without-readline to disable readline support.

Are you *sure* that readline is installed in those directories

Have you checked config.log to see the actual error message from the
linker?

Hi.. thanks.

Here's a printout from my find command:

/usr/local/include/readline
/usr/local/include/readline/readline.h

And the plot thickens. Here is where it errors out and then loops
endlessly until it quits:

What happens if you run

ldd /usr/local/lib/libreadline.so ?

It looks like you've got either multiple versions of readline
installed and you're linking to the wrong one, or something is really wonky
with your readline build. A quick google is showing that all of those
symbols are in ncurses, which means that you should probably have ncurses in
your linker cache or linker runtime path.

By the way, if you don't want readline functionality in psql (or care),
just build '--without-readline'

Hi...Here's the output of that one:

ldd /usr/local/lib/libreadline.so
linux-gate.so.1 => (0xffffe000)
libc.so.6 => /lib/libc.so.6 (0xb7e9c000)
/lib/ld-linux.so.2 (0xb8055000)
ddev:/ #

There are two versions of readline. REadline 5.2 and Readline 6.0
Readline 5.2 was installed during
the suse linux installation but it never installed the readline.h
file. Go figure.

Not really sure what the problem is then, it's probably obvious but I'm
jet-lagged and running on low blood sugar /caffeine right now.

There are two versions of readline. REadline 5.2 and Readline 6.0 Readline

5.2 was installed during
the suse linux installation but it never installed the readline.h file. Go
figure.

The easiest way to deal with that is just to install the 'readline-devel'
package via YaST. That may help.

You should keep reading past that point ...

The missing symbols here can come from termcap or ncurses. There
is code in our configure script to try linking readline with those
additional libraries. What's not clear is why those attempts failed,
but you didn't show us the trace of them failing.
