Apparent gcc error when building pysqlite


Dear all,

I'm something of a n00b, so please be gentle.

I'm running Ubuntu 8.04

I've got sqlite3 installed, but I keep getting errors when trying trying to install pysqlite (2.4.1 or 2.5.1).

If I run
$ python setup.py build
things look like they're going ok for a while, but then I soon start getting errors:

running build
running build_py
running build_ext
building 'pysqlite2._sqlite' extension
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -DMODULE_NAME="pysqlite2.dbapi2" -I/usr/local/include /usr/bin -I/usr/include/python2.5 -c src/module.c -o build/temp.linux-i686-2.5/src/module.o
In file included from src/module.c:24:
src/connection.h:26:20: error: Python.h: No such file or directory
[snip]
There's a whole load more stuff, ending up with:

src/module.c:303: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘init_sqlite’
error: command 'gcc' failed with exit status 1


gcc -v tells me that gcc exists so I think that last error must be a red herring. However, after searching the web and trying lots of things, I've not managed to build pysqlite.

In case it's relevant, setup.cfg contains the following (after attempts at various things having tried following up on some suggestions I found posted elsewhere):

[build_ext]
#define=
#include_dirs=/usr/local/include
#library_dirs=/usr/local/lib
libraries=sqlite3

I'd be very grateful to anyone who has any suggestions. Again, I'm a newbie so please keep that in mind.

Many thanks,
TolstoyTheCat

You are missing the Python development files
Code:
src/connection.h:26:20: error: Python.h: No such file or directory
. On a binary distro like Ubuntu, they are named something like Python-dev or Python-devel. Use your pacakge manager to find the right package.

python-dev

I've now build and installed pysqlite just fine.

Many many thanks. I'm very happy now!

Ugh! Ok, so it built and installed, but now I'm getting a new problem when I try to run a simple Python script that uses pysqlite:

Traceback (most recent call last):
File "firstGo.py", line 1, in <module>
from pysqlite2 import dbapi2 as sqlite
File "/usr/lib/python2.5/site-packages/pysqlite2/dbapi2.py", line 27, in <module>
from pysqlite2._sqlite import *
ImportError: /usr/lib/python2.5/site-packages/pysqlite2/_sqlite.so: undefined symbol: sqlite3_enable_load_extension

So I guess I'm missing something else from my Python installation. Once more, any help will be appreciated. Please let me know if I should be asking this sort of stuff elsewhere.

Ta,
TolstoyTheCat
