Getting errors / failing tests when installing Python3.4.3 on Lubuntu 14.04

Tags:

python

installation

ubuntu-14.04

python-3.4

I use VMplayer and my OS is Lubuntu 14.04. It comes with a pre-installed python3.4.0 but I want to install python3.4.3. I downloaded the .tar.xz file from here.

I then extracted the file and followed the instructions in the README:

./configure
make
make test

When I initially ran

make test

it said "3 tests failed, 3 altered execution environment and 25 skipped". I posted the question on SO here: Installing Python3.4.3: 3 tests failed, 3 altered execution environment and 25 skipped

I then did

sudo apt-get install libssl-dev

and did

./configure
make

again and it said:

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses               _curses_panel      
_dbm                  _gdbm                 _lzma              
_sqlite3              _tkinter              readline           
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

Now when I tried

make test

it said 

1 test failed:
    test_ssl
2 tests altered the execution environment:
    test___all__ test_warnings
21 tests skipped:
    test_bz2 test_curses test_dbm_gnu test_dbm_ndbm test_devpoll
    test_gdb test_idle test_kqueue test_lzma test_msilib
    test_ossaudiodev test_readline test_sqlite test_startfile test_tcl

make: *** [test] Error 1

There was a bit more code in the middle but I deleted it because it would exceed the body limit. Nonetheless, the main thing is, 1 test failed, 2 tests altered the execution environment and 21 tests skipped.

Any idea why I'm getting failed and skipped tests even though I followed the exact steps on the Python downloads page? Is there an easier way to install Python3.4.3 on my OS?

Resolving OP Question

From the test Python has built OK. "Python build finished successfully!" The missing modules are there because you don't have the relevant software installed on your computer.

This is no different to using apt-get so for example your missing _tkinter this is because you don't have the packages necessary to run it. So if you were using apt-get you would have to use apt-get install python-tk so that apt-get would pull in the relevant dependencies. The logic being if you don't have the software installed your not going to need the modules to program it.

The only concern that I can see with the make tests is the failure of ssl.

1 test failed:
    test_ssl

looking down the test results you will see :-

test_ssl: testing with 'OpenSSL 1.0.1f 6 Jan 2014' (1, 0, 1, 6, 15)
      under Linux ('debian', 'jessie/sid', '')
      HAS_SNI = True
      OP_ALL = 0x-7ffffc01
      OP_NO_TLSv1_1 = 0x10000000

This version of OpenSSL contains the SSL protocol vulnerability that was discover last year and was fixed in OpenSSL 1.0.1j [15 Oct 2014]. You can find this information here.

I am not really up on Ubuntu as I use Fedora but you could try :-

apt-get update
apt-get dist-upgrade

And see if this fixes the SSL vulnerability that your computer has.

Installing From Source

On a side note if your looking to develop Python apps for systems other than the one your using, installing from source is the only way to go.

There are many good reasons to compile from tar.gz.

  1. most Linux distros use Python internally so are linked to a version.

  2. you can get conflicts between modules that you import.

  3. you can test your code against different versions of python.

  4. you don't need root permissions set up your own versions so what you do is independent of anything the operating systems needs.

So for this example my home is /home/paul and I have created to directories in the root of my home. One call src which I will use as the source directory and one called opt that will hold my Python versions.

The trick is to tell Python where the install is to go. So put the tar.gz file in the src directory and expand it. Open the terminal and ...

cd ~/src/Python-X.X.X
./configure --prefix=/home/paul/opt/python.x.x.x
make
make test <optional>
make install

Note at no time did I use sudo as I have rights to my home directory and I am not effecting anything else on the system.

Now to test ...

~/opt/python.3.4.2/bin/python3
Python 3.4.2 (default, Mar 28 2015, 19:36:24) 
[GCC 4.9.2 20150212 (Red Hat 4.9.2-6)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

And you can just keep adding test versions as new versions come along just remember to start your code by pointing to the version you want to use.
