We have compile python 3.4.1 in Suse Linux Enterprise Server 11 SP2

We have compiled it using --prefix as args :

./configure --prefix=/soft/pyt341


make install

We check python has been properly installed:

/soft/pyt341/bin/python3 --version
Python 3.4.1

We try to import sqlite3 lib and we get this error:

/soft/pyt341/bin/python3 -c "import sqlite3"

Traceback (most recent call last):

Did you install sqlite3-devel?
msg222659 - (view) Author: Alejandro (alexganwd) Date: 2014-07-10 12:19
Yes. We have these packages installed:

rpm -qa | grep sqlite

The output from running `make` could help by pointing out either a compilation error or lack thereof to deduce that did not find the headers.

Hi, I've the same problem. 
I've already tested (from source, Python-3.4.1.tgz) under OpenSUSE 12.3 and Debian 7.5 with the same issue. I've compiled it in standard way (./configure; make; make install) although the output (error) is the same, after import sqlite3:

#python3 -c "import sqlite3"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3.4/sqlite3/", line 23, in <module>
    from sqlite3.dbapi2 import *
  File "/usr/lib/python3.4/sqlite3/", line 26, in <module>
    from _sqlite3 import *
ImportError: No module named '_sqlite3'

However, if I install it using specific distro packages it works properly.

Works for me on Ubuntu 12.04 LTS:

   $ sudo apt-get install sqlite3 libsqlite3-dev
   $ ./configure
   $ make -j3
   $ sudo make install
   $ sqlite3 -version
   3.7.9 2011-11-01 00:52:41 c7c6050ef060877ebe77b41d959e9df13f8c9b5e
   $ python3.4 -V
   $ python3.4 -c "import sqlite3; print(sqlite3.sqlite_version)"

I've downloaded UBUNTU 12.04. I've compiled python3 and I got the same error.

Chiming in here as a SUSE guy;

Can you make sure 


does exist. If yes run ldd on it

ldd /usr/local/lib/python3.4/lib-dynload/

And also give output of "which python3.4" to make sure you are running the right python instance.
msg222744 - (view) Author: Alejandro (alexganwd) Date: 2014-07-11 14:12
we have  /usr/local/lib/python3.4/lib-dynload/ but we didn't have it in /soft/pyt341/lib/python3.4/lib-dynload/

After copying it into /sofy/pyt341.... the problem was solved!! ;)

/soft/pyt341/bin/python3 -c "import sqlite3;print(sqlite3.sqlite_version)"

In my opinion running ./configure should check if sqlite libs are properly satisfied and break compilation if they aren't installed. 

I don't know if this issue could be considered a bug. So I will close it as "works for me"

Thanks for all!

You're absolute right that file is not in path. 
However, in my view this a  bug, due to the fact libsqlite3-dev package must be installed before Python3.4.1 is compiled (or install it and recompile python) because there is no errors, no warnings... nothing.

In any case, thanks a lot for your help. This solution works for me.

If the headers are missing, you will get a complaint at the end of the make process that it couldn't build the _sqlite module.  It should also have tried to import the sqlite3 module and complained if there was an error.  So, pre-install, everything looked fine to the build process.

Can you attach your 'make install' log?

(Berker: a key difference in your test is that OP specified an alternate --prefix)
msg223400 - (view) Author: Alejandro (alexganwd) Date: 2014-07-18 07:05
Here you have make_install.log

msg223415 - (view) Author: R. David Murray (r.david.murray) * (Python committer) Date: 2014-07-18 15:44
The install log shows the file being copied into place:

copying build/lib.linux-x86_64-3.4/ -> /soft/pyt341/lib/python3.4/lib-dynload

This does not line up with the fact that you said the file did not exist after the install.  Something would have to be deleting the file after it got copied into place.  After you run make install, is there anything at all in lib-dynload?
msg223416 - (view) Author: R. David Murray (r.david.murray) * (Python committer) Date: 2014-07-18 15:47
configure with a prefix followed by make/make install works fine for me, by the way (on a Gentoo system).

Closing this for now since we couldn't reproduce the problem and haven't heard back from the OP in a while.
