I am trying to build vim on Ubuntu 12.04 with python3 support as the default install only has python2 support. I pull the source code from https://vim.googlecode.com/hg/ and configure like so:

./configure --disable-pythoninterp --enable-python3interp --with-features huge

I tried with the --enable-pythoninterp option also.

When I run vim --version on this install I still get -python3 like so:

$ ./src/vim --version

As can be seen in the above, python3 support is not included in the binary.

I also have python3-dev installed too, although I'm sure if that's required.

sudo apt-get install python3-dev

Any help would be much appreciated!

Thanks

You also need to specify the python config dir with

--with-python3-config-dir=

when running configure since it appears that configure wasn't able to automatically find the directory.

The other way to make configure find that python3-config-dir automatically is make sure that python points to a python 3 executable instead of a python 2 one (which most systems default to)

I would also recommend running configure with --enable-fail-if-missing so that the configure script will fail instead of quietly warning that it didn't find a python3 config directory or executable.

Building Vim from source

  • First, install all the prerequisite libraries, including Mercurial. For a Debian-like Linux distribution like Ubuntu, that would be the following:

bash sudo apt-get install libncurses5-dev libgnome2-dev libgnomeui-dev \ libgtk2.0-dev libatk1.0-dev libbonoboui2-dev \ libcairo2-dev libx11-dev libxpm-dev libxt-dev python-dev \ ruby-dev mercurial For Fedora 20, that would be the following:

bash sudo yum install -y ruby ruby-devel lua lua-devel luajit \ luajit-devel ctags mercurial python python-devel \ python3 python3-devel tcl-devel \ perl perl-devel perl-ExtUtils-ParseXS \ perl-ExtUtils-XSpp perl-ExtUtils-CBuilder \ perl-ExtUtils-Embed

  • Remove vim if you have it already.

bash sudo apt-get remove vim vim-runtime gvim vim-tiny vim-common vim-gui-common

  • Once everything is installed, getting the source is easy. If you're not using vim 7.4, make sure to set the VIMRUNTIMEDIR variable correctly below (for instance, with vim 7.4a, use /usr/share/vim/vim74a):

bash cd ~ hg clone https://code.google.com/p/vim/ cd vim ./configure --with-features=huge \ --enable-multibyte \ --enable-rubyinterp \ --enable-python3interp vi_cv_path_python3=/usr/bin/python3.4 \ --with-python-config-dir=/usr/lib/python3.4/config-3.4m-x86_64-linux-gnu \ --enable-perlinterp \ --enable-luainterp \ --enable-gui=gtk2 --enable-cscope --prefix=/usr make VIMRUNTIMEDIR=/usr/share/vim/vim74 sudo apt-get install checkinstall sudo checkinstall

  • Set vim as your default editor with update-alternatives

bash sudo update-alternatives --install /usr/bin/editor editor /usr/bin/vim 1 sudo update-alternatives --set editor /usr/bin/vim sudo update-alternatives --install /usr/bin/vi vi /usr/bin/vim 1 sudo update-alternatives --set vi /usr/bin/vim

Done
