Installation

This tutorial will walk you through the process of installing Pylo. To follow, you really only need three basic things:

• A UNIX-like machine with web access.
• A C++ compiler, preferably a Version 4.x gcc.
• A working Python installation, Version 2.4 or newer.

You may adapt the file and directory names in this tutorial to suit your liking, just be sure to be consistent in your changes.

Note

Whenever you see the “$” dollar sign in this tutorial, this means you should enter the subsequent text at your shell prompt. You don’t have to be root. A few spots are marked with “sudo” to show that these do require root privileges if you are using a Python interpreter that is installed globally.

Step 1: Install pyublas

Note

If you have already installed hedge, then you automatically also already have pyublas, and you can skip this step.

The first step in this installation is to install PyUblas. To achieve this, please follow PyUblas’s installation instructions.

Step 2: Download and build libsilo

Download the Silo source code, version 4.6.1 or newer. Then unpack, build and install it:

$ tar xfz ~/download/silo-N.N.N.tar.gz
$ cd silo-N.N.N
$ ./configure.py --prefix=$HOME/pool --enable-shared=yes --enable-static=no
$ make install

Step 3: Update your build configuration file

During prior steps of this installation, you will have created a file called .aksetup-defaults.py in your home directory. Now add the following lines to this file:

SILO_INC_DIR = ['${HOME}/pool/include']
SILO_LIB_DIR = ['${HOME}/pool/lib']

You will need to adapt the above path names to the location where you installed the Silo software, of course.

Note

Make sure not to miss the initial dot in the configuration file name, it’s important.

Note

The order of the entries in the build configuration file does not matter.

Step 4: Download and unpack PyVisfile

Download PyVisfile and unpack it:

$ tar xfz pyvisfile-VERSION.tar.gz

Step 5: Build pyvisfile

Just type:

$ cd pyvisfile-VERSION # if you're not there already
$ sudo python setup.py install

Once that works, congratulations! You’ve successfully built pyvisfile.
