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:/ # 

   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.

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:

(There are symbolic links from libreadline.so to libreadline.so.6.0)

   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'
