I have installed Python 2.5 on my new Intel Mac but I can't for the life
of me get readline to work. I have libreadline installed, I've tried
copying readline.so from my Python 2.3 installation into 2.5, I've
searched the web, and no joy. Could someone please give me a clue?

Where have you installed libreadline? Is LD_LIBRARY_PATH pointing to the
directory libreadline.dylib? Did you install libreadline with fink? If
so, try

setenv LD_LIBRARY_PATH /sw/lib

before compiling (csh).

Bash (OSX default) and similar shells use this silly 2 part syntax:

LD_LIBRARY_PATH=/sw/lib
export LD_LIBRARY_PATH

Do a "locate libreadline.dylib" and set the LD_LIBRARY_PATH to the
containing directory and then

make clean
./configure
make
make install

or similar.

Does the info in a blog article that I wrote help?

http://www.razorvine.net/frog/user/i.../2006-05-08/87

I used this when I compiled my Python 2.5 on my mac, and
it seemed to work

I'm now using the python.org binary distribution though and that seems to
contain a working readline as well.... ?

No, because I'm not using Fink. But maybe I can adapt your solution.

I'll try that too.

/usr/local/lib

It wasn't, but changing it so it did didn't fix the problem. (I didn't
try recompiling Python, just running it. I'll try rebuilding later.)

No, I just got the source from the FSF and did ./configure ; make install

Actually you can do it in one line: export LD_LIBRARY_PATH=whatever

I'll give that a whirl. Thanks.

You must re-compile python, starting with configure so that configure
can identify the readline libraries. Otherwise it will compile with no
readline, which is your current situation

Ok. Now I'll switch to bash.

That did the trick. Thanks!

Hi James, hi Ron,

That would probably make no difference since on Mac OS X that variable
is called DYLD_LIBRARY_PATH (contrary to SysV Unices).

It's just your way of using it that makes it a 2 part syntax:

export DYLD_LIBRARY_PATH=/sw/lib

does the trick. And by the way: the bash construct is far less error
prone regarding quoting when used in shell scripts.
