Re: interactive terminal in Ubuntu Linux : libreadline5-dev works only in Python 2.6 not 3.1
The python 3 version in the 9.10 repo is 3.1.1 Actually, if I/O is important, I'd recommend a full install of 9.10 so that you can get the ext4 file system. I have found it offers some very impressive speedups with the disk -- especially for deleting files. Thanks casevh and Lee. I intend to remove all versions python 3, update Ubuntu to 9.10 and then do a clean installation of python 3.1.1 via Synaptic. Dave WB3DWE -- http://mail.python.org/mailman/listinfo/python-list
Re: interactive terminal in Ubuntu Linux : libreadline5-dev works only in Python 2.6 not 3.1
When you first had this problem, was python3 installed from source, or was it from the Ubuntu repository? Over a month ago I downloaded the tarball Python-3.1.1 from the python website. Then the Synaptic Package Manager did not contain this ( latest ) version. There is already python 2.x on my Ubuntu 9.04 ( think its 2.6 ). Think I saw 3.0 on Synaptic but not 3.1 Supposedly 3.1 has faster i/o . If you are mostly using your Ubuntu system to work with Python 3.1, I recommend upgrading to 9.10 if that is not a big problem.

Re: interactive terminal in Ubuntu Linux : libreadline5-dev works only in Python 2.6 not 3.1
And my original problem still there : fouled up keys in interactive terminal. When you first had this problem, was python3 installed from source, or was it from the Ubuntu repository? (ie, did you install using apt-get or synaptic or did you just start out building from source?) I have python 3 on Ubuntu 9.10 installed using synaptic and readline works fine. If yours was from the repo, it's possible that the problem is not python, but your terminal emulator. Which terminal program are you using (xterm, konsole, gnome-terminal, etc)? _ Windows Live: Make it easier for your friends to see what you’re up to on Facebook. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_2:092009 -- http://mail.python.org/mailman/listinfo/python-list

I struggled with Linux for several weeks. On Jan 2 I attempted installation ( in dir containing Python-3.1.1 ) with : $ ./configure $ make $ make test $ sudo make install Did not seem to work ( didn't record exactly what happened, perhaps I didn't put in sudo ), so I ran above again. Did not use altinstall. Did not get the tarball with apt-get or from Synaptic. Just downloaded it from python site. The readme gave the build instructions above. I've exclusively used gnome. Quite happy with gedit's handling of python code. I shouldn't have been greedy and should have settled for 3.0 from Synaptic. Now I have problems with three versions on my machine. Please see my exchanges with casevh for details. Perhaps the best solution would be to wipe off all 3.1 versions and simply install 3.0 from Synaptic. This whole thing with the Python interactive interpreter keys actually started with my sons, who are Mac enthusiasts. One gave me a MacBook. Alas the Python interpreter keys were fouled up, as well as it having a simplified keyboard. Apple took it back, but it was disconcerting when I found the same key problem in Ubuntu python 3.1 Apple must change their software as I retried a new MacBook yesterday. To my great surprise the python 2.6 interpreter worked fine, while on at least two MacBooks last month it did not.

On Jan 6 I inquired how to fix the 3.1.1 interactive terminal in Ubuntu Linux. Left arrow yields ^[[D , etc. casevh helped by suggesting libreadline5-dev be installed. Did so with Synaptic Package Manager. The behavior of the Python 3.3.1 terminal is unchanged but the 2.6.2 terminal is corrected. Is there any way to fix the 3.1.1 terminal command line ?

Python recompiled and the system appears to be in same path/dir as before : /home/dave/python31/Python-3.1.1 Called up interactive prompt with $ python3 , as before. It looks like you now have two copies of Python 3.1.1 installed. That's probably a side-effect of my instructions. I'll got through each instruction individually. It looks like your Python source code is in /home/dave/python31/ Python-3.1.1. The commnad make distclean should remove the results of the prior configuration so to won't need to extract the source code again. The command ./configure accepts several options that control how the source code is configured. To see all the available options, use the command ./configure --help. The first option - --prefix=/usr/local - identifies the location where Python 3.1.1 will be installed. The / usr/local directory is a common location for user-compiled programs. If no location is specified, many applications assume /usr/local. The option - --with-computed-gotos - is just a compiler options that produces a slightly faster interpreter. The final option - --with- wide-unicode - identifies the proper Unicode format to use. (I looks like this option may have been split via line wrapping on my earlier email. I think it is causing the UCS4 error.) The command make compiles Python 3.1.1. The command sudo make altinstall installs Python 3.1.1 under the / usr/local directory. The option altinstall installs Python 3.1.1 and leaves its name as python3.1. It should be located in /usr/ local/bin/python3.1. Your own programs (Ackermann.py) should be kept somewhere in your home directory, for example /home/dave/code. Typing python3.1 will look in the current directory first, and then search the path where it should find /usr/local/bin/python3.1. What will you need to do fix this? 1) Try the commands again. Make sure all the ./configure options are on one line. Make sure to do sudo make altinstall. (Don't use sudo make install; it will give your version of Python the name python and that can cause confusion on your system.) 2) Move your applications to another directory. 3) Try running python3.1 while you are in that directory.
