Portable Python build script for Linux

This is a build script that will build a portable Python distro for either 321 bit or 64 bit Linux distros. This Python is portable which means that it can be copied to any directory on any Linux install (that is not too much older than your build machine) and it will all work.

This Python distro contains Python 2.7.2 and the standard library as well as a bunch of other modules that I find useful. Many of the modules have binary shared libraries as part of them and the main challenge of building is to arrange things so that all binary shared library dependencies are included in the Python distro and are used in place of any similar system libraries. This means that you can use the lxml module even on a Linux install that does not have libxml installed.

Building binary modules is a real adventure and if you look through the script you will see many divergences from the simple ./configure;make;sudo make install that are the ideal way to do a build. Hopefully you will be able to use these as examples to add your own binary modules to the script.

Pure Python modules are a non-issue. Once you have the portable Python distro built (and PATH variable set) then just run pip install mymodule and then remake the tarball. In fact, many binary modules can be built by pip as long as you first set some environment variables and then do the binary fixups afterward.


The portable magic is all done by using the RUNPATH and RPATH headers in the Python binary and in all of the shared libraries. If you have tried using RPATH before and written it off as too complex, then have a look at the technique that I used because it manages the complexity. First of all, the magic name of $ORIGIN that is used in RUNPATH headers to direct the dynamic linking process, is a bad design choice and causes lots of issues in building code. My solution is to use XORIGIN instead, and then patch it back to $ORIGIN after the binary libraries have been built. To do the patching I use a utility called patchelf that is part of a very interesting Linux distro called Nixos.

The build process has only been tested on Ubuntu and Debian installs, and the easiest way to try it out is to install a fresh VM of Ubuntu Lucid (using VirtualBox) and then check out pybuild and run it. It should just work and will pull in (via apt-get) any OS dependencies needed. If you have local mirrors for Ubuntu or PyPi then you can set a couple of variables in and it will keep your traffic off the Internet. I have also run the build on Debian Etch.
