This was very helpful! Thank you for posting these instructions. They’re useful for me as a beginner with Python (trying to start out on the latest version).

What Matt says! Thanks for posting!

Good tip. I posted a similar recipe that uses readline from MacPorts, which may be convenient for some people. http://chrismiles.livejournal.com/25648.html

I follow the instructions, but with my 10.5.5 I had to compile and install readline with command

6. ./configure
make static && sudo make install-static

It gave me some error “-compatibility_version only allowed with -dynamiclib”

How would I get readline support if I already have Python 3.0 installed? Thanks.

Will this work with ox 10.5.6?

When I tried it I got this:

patch unexpectedly ends in middle of line
patch: **** Only garbage was found in the patch input.

help?

Great! That really helped as there is no easy .pkg as there is for 2.6
One small question: I also have 2.6 installed and want to keep it that way. Will I run into any conflicts?

Excellent tips, thank you.
Everything seemed to go smoothly with the readline and subsequent Python install, and I can run Python3.0. Great!

Trouble is I can’t run IDLE because of some Tk version conflict. I likely caused this myself with some Tcl/Tk install a while back … but how to fix? Error message at end.

The only Tk 8.5 I can find on the machine is in /Library/Frameworks… while /System/Library/Frameworks… has 8.4

Can IDLE3.0 be made to run in this situation? What to do?

Thanks very much!

patch readline-012 doesn’t seem to work – ‘patch’ comes back with a prompt
saying “What file do you want me to patch?”

All of the other patch files seem to include the file to patch…

Skipping patch readline-012 and moving on to 013, 013 works, but a subsequently build fails due to some conflict between -compatibility-with and the -dynamiclib option.

I’m guessing this is fixed by 012, which didn’t get applied.

I also had problems trying to apply patch 12. Then I tried the -p option with every file and it worked; something like…

patch -p0 < readline52-001

It compiled just fine

Cheers!

Wow! Thanks! I’ve been wanting 3.0 on my Mac, but the Python site just referred me to the Wiki site. Said nothing about “if you want to go to a little effort, here are the ingredients.” I found your article and now all is well with the world.

@Arkham: Thank you!

I just have a few doubts. Do we need to compile against readline(3)? From the Python manual included in Leopard I read it works with editline(3). I did a:

$ ls -l /usr/lib | grep readline

and I can see there’s a link from libreadline to libedit:

lrwxr-xr-x 1 root wheel – 15B Feb 2 02:35 libreadline.dylib@ -> libedit.2.dylib

If we compile Python 3.0 with no –with-readline-dir, do we get a Python with editline support?

Man, but readline is so wicked already!

And, is the –with-readline-dir a common configure option in GNU software? Is it documented in Python?

Cheers,

P.D.: Everybody, please excuse my english, I try my best

@Arkham: Thanks for the info. That’s what I thought (about the command line functionality). I read something about the BSD license in the default Python manual, I think. All in all it’s just burocracy.

I’ll stay with readline support, which goes pretty well with my bash setup. I even got history-search-backward (and forward) and other stuff through bindings in my .inputrc. Very nice indeed. I guess you can configure that sort of thing with editrc but didn’t want to learn another set of functions for now (I’m a Unix newbie and already studying enough subjects).

It’s a shame Python docs do not mention the readline configure option. I’m glad you posted this

Cheers!

Does this work on PPC as well as x86? My poor PowerBook seems to hang every time I get to:

gcc Python.framework/Versions/3.0/Python -o python.exe \
Modules/python.o \
-ldl

Far and away too difficult for me. I have used macs 20 years but have no Terminal experience.
I guess Python is not so simple after all.

@Alan Williams

You don’t need to install Python 3.0 to explore the language. Why don’t your try the default python installation (version 2.5.1).
Just open terminal, type python and press enter. To exit type Ctrl-D or type these lines (followed by enter):

import sys
sys.exit()

Happy hacking

well.. it’s like I said!

Readline seemed to install nicely, but…

gcc Python.framework/Versions/3.0/Python -o python.exe \
Modules/python.o \
-ldl
ld: warning: in Python.framework/Versions/3.0/Python, file is not of required architecture

This seems to be getting me further than any other website that talks about installing the latest Python. I seem to still be having trouble though. In the terminal, I get the correct file directory for the patch, however I get this error message

“patch unexpectedly ends in the middle of line
patch: **** Only garbage was found in the patch input.”

What do you think I am doing incorrectly?
