Mercurial (hg) Installation Without Being Root

Solutions for installing mercurial from a package repository or via a self-extracting or any other installer for all operating system distribution can easily be found. So this is not the topic of thise Wiki entry. Here we cover the installation of a mercurial versioning system without root access. It is a necessary step for the creation of our synergetic hard and software development system that at a later point shall be mirrored by the Wiki to keep it up to date and to keep development efforts bundled in our versioning system (mercurial, git, svn, bzr, ...).

With a Python installation readily available or with rights to install a python environment:

If a python installation is available or you have a server where you have adminsitrative rights for installing the python and still want to have a local installation of mercurial into your home directory, this also is no problem by using the Mercurial script: make install-home (to include documentation) or make install-home-bin (for the executable only). If you used a custom python location for the script it is required to add the following to the command to communicate it to hg:

$ PYTHON=/path/to/python2.4-or-newer

$ make install-home

Without Root access and no Python available:

To install mercurial without being root, needs us to bundle Python 2.x (as Python 3 is not yet supported as there is only one advantage in favour of upgrading, so it's not worth the effort currently).

Windows

For Windows there currently is PortablePython as a ready made option.

UNIX

For UNIX systems (Mac OS, GNU/Linux, Android, ...) or FreeBSD there are some packages floating around in the net, but it's sometimes hard to find the correct one for a certain architecture and operating system (what is needed to match the server's arch and os).

So if you have a system similar to the web server available where you have root access, the following is an option of how to get a working mercurial and python.

Virtual / bundled installation of Python

To create a virtual/bundled installation of Python and Mercurial there are two or more quite similar ways.

We will proceed in adapting this splendid blog entry of Fabrizio: https://weblogs.java.net/blog/fabriziogiudici/archive/2009/07/installing_merc.html .

For now it turned out that the blog post is no longer up to date as there will not be a binary for mercurial, namely 'python2/bin/hg' is missing.

To fix this:

$ tar -xvf mercurial_bundled_python.tar.gz

$ cd mercurial_bundled_python/

either

$ make install-home-bin

$ hg # should show version

or

$ make local # build for inplace usage

$ ./hg --version # should show the latest version

Problems that might occur (and occurred for me)

If a 'dependency unmet' error occurs when trying to install python2.7-dev then follow the solution I proposed in this thread:

1. sudo apt-get install aptitude
2. sudo aptitude install python2.7-dev
3. skip first proposed solution [Not installed] and wait for the next solution to be proposed:
4. take the solution to downgrade the dependencies.

Also a bunch of i386 programms will propably be removed during the process. (just trust Linux!) http://stackoverflow.com/questions/19738218/error-processing- python2-7-minimal/21080087#21080087
