Vim compilation with --enable-pythoninterp on Ubuntu

[Senthil Kumaran]

This one seems tricky, because I tried every suggestion on www. I could do any experiment which could be helpful to compile vim with python interpreter support.

I am trying to compile vim from source with python interpreter on Ubuntu. I have installed the dependencies for vim, installed python2.7-devel and python2.7-dbg packages on Ubuntu and do the configure step like this

./configure --enable-pythoninterp --with-python-config-dir=/usr/lib/python2.7/config

The config directory does contain the config.c file. The make step fails with the following error.

...

objects/py_config.o:(.data+0xcc): undefined reference to `initcStringIO'
objects/py_config.o:(.data+0xd4): undefined reference to `initcPickle'
objects/py_config.o:(.data+0xdc): undefined reference to `initzlib'
collect2: ld returned 1 exit status
make: *** [vim] Error 1

I have tried stable builds, tweaked around configure etc. But do not find a definitive answer. Also vim builds without the python-interpreter.

Here the complete

output - http://paste.pocoo.org/show/577749/

error - http://paste.pocoo.org/show/577752/

Makefile - http://paste.pocoo.org/show/577751/

I am experimenting with this at the moment so the following is
based on floundering around, not actual knowledge, however I
have recently built Vim 7.3.494 on Fedora 16 with Python 2.7.

I used following, then make:

./configure --with-features=huge --prefix=$HOME/opt \
--enable-pythoninterp \
--with-python-config-dir=/usr/lib/python2.7/config

src/Makefile includes:
objects/py_config.o: $(PYTHON_CONFDIR)/config.c

The file /usr/lib/python2.7/config/config.c does not contain any
of the identifiers that give the errors above, so my guess is
that you have a mixture of files from Python 2.7 and some
earlier version.

That's a useful clue. I have the source of Python and I see that those modules defined Module/config.c in the Python source. Instead of pointing to source, I pointed to default install of Python from Ubuntu. Perhaps some problem lies there, let me try in to source or a local prefixed install of Python from source and then try to compile vim against it.

Thanks,

That was it. I compiled Python from Source location and did an alternate installl and then pointed to it. The vim compile was successful. The problem then seems to be python installed via Ubuntu.

However, I am facing another problem, the compilation seems to make the path my system python instead of local installed python. I get this error when I try to start vim

Hello,

How can I make vim compilation to take a custom PYTHON_CFLAGS value.
I tried,

PYTHON_CLAGS=-I/home/senthil/localpython/include/python2.7

in the shell before compilation and then tried to change that value in Makefile. but it python linker still points to system python ( Ubuntu one does not seem to help vim python configure).

After setting the PYTHON_CFLAGS, I would like to run:

./configure --enable-pythoninterp --with-features=huge --with-python-config-dir=/home/senthil/localpython/lib/python2.7/config

Thanks,
Senthil
