Disorder

h1. Installation

h2. Obtaining the Source Code

h3. Release Tarballs

Release source tarballs are available on the "Files":http://oss.squalllinesoftware.com/projects/disorder/files page.  This is what you want if you are looking for stability and something ready for production use.  You'll probably want to use the most recent version found on that page.

h3. SCM

The Disorder source code is hosted in a "Bazaar":http://bazaar.canonical.com repository.  This is what you want if you are looking for the very latest bleeding edge of the code for contributing to Disorder or whatever other reason you may have.

Read the "Bazaar Documentation":http://doc.bazaar.canonical.com/en/ if you aren't familiar with that and you want to go this route.

To get a lightweight checkout of the latest version without all the history (not suitable for Disorder development):

<pre>bzr co --lightweight bzr://bzr.squalllinesoftware.com/disorder</pre>

To clone the repository including the full history:

<pre>bzr branch bzr://bzr.squalllinesoftware.com/disorder</pre>

h2. Prerequisites

The following third party things are required to use Disorder:

* "Boost":http://www.boost.org >= 1.49.0

* "Eigen":http://eigen.tuxfamily.org >= 3.0.5

* C++ version of the "SEDRIS SRM":http://www.sedris.org/srm_4.4/srm_c_cpp.htm >= 4.4.0 (optional but you will need some kind of sophisticated geospatial library)

* A "Python":http://www.python.org interpreter (needed to use the "waf":https://code.google.com/p/waf/ build system)

Build and install these things in accordance with the instructions for your operating system provided by each vendor.  Some hints for certain platforms follow.

h3. Debian Linux and Derivatives

Pat yourself on the back for using a good operating system.  All the dependencies are available via the package system.  To install the Boost and Eigen build dependencies on Debian and maybe other derivatives:

<pre>sudo apt-get install libboost-dev libboost-system-dev libboost-thread-dev libboost-date-time-dev libeigen3-dev</pre>

If you don't already have python, this will get the required bits of that:

<pre>sudo apt-get install python</pre>

h2. Configuration

If everything is setup properly, this step will be a breeze, but it is important to resolve any errors produced by the configuration step prior to attempting to compile Disorder.

h3. Linux

From inside the root of the Disorder tree do this in your favorite terminal emulator:

<pre>./waf configure --sedris-srm-root=<put the path to the SEDRIS SRM root here></pre>

For example, if your SEDRIS SRM is in /opt/sedris/srm:

<pre>./waf configure --sedris-srm-root=/opt/sedris/srm</pre>

That command will take several seconds and print a bunch of hopefully green stuff.  The output should end up looking something like this:

<pre>

'configure' finished successfully (25.518s)

</pre>

If you get an error instead of that last line saying that 'configure' finished successfully, you must fix whatever is making it unhappy and try again.

h4. Clang++

To use the Clang C++ compiler instead of GCC, assuming clang++ is installed on the build system:

<pre>CXX=<put the path to clang++ here> ./waf configure --sedris-srm-root=<put the path to the SEDRIS SRM root here></pre>

For example:

<pre>CXX=/usr/bin/clang++ ./waf configure --sedris-srm-root=/opt/sedris/srm</pre>

h3. Windows

On windows, your $PATH environment variable needs to include the path to the Python interpreter.

Next, you'll probably want to modify the provided batch file to tell Disorder where your prerequisites live.  From inside the root of the disorder tree:

<pre>copy tools/configure.bat configure.bat</pre>

This file contains some stuff at the top you'll want to edit to match your system configuration.

h2. Compiling

The basic strategy for building Disorder is to invoke the waf build system with the desired build variant.

Disorder has two build variants:

* debug: produces a library that contains debugging symbols and disables most compiler optimizations

* optimized: produces a library stripped of debugging symbols and enables compiler optimizations for performance

It might be reasonable to use the @debug@ variant in a development environment and the @optimized@ variant in a production environment.

The @debug@ variant is produced by the @build_debug@ build target and the @optimized@ variant is produced by the @build_optimized@ build target.

The results of the build are put in the @bin@ subdirectory under the name of the variant.  

Both variants can coexist peacefully in the tree at the same time.

h3. Linux

On Linux, to build the Disorder @debug@ variant:

<pre>./waf build_debug</pre>

h3. Windows

On Windows, the waf script is invoked indirectly.  To build the @optimized@ variant:

<pre>python.exe waf build_optimized</pre>

h2. Building Against the Disorder Library

h3. Compiling

In order to compile your goodness against the Disorder library, you'll need to have the header files from the @src@ directory in the Disorder tree and Eigen's include directory in your compiler's include path.  You do not need anything from SEDRIS SRM in your include path.

h3. Linking

Just link your program against Disorder's static library that you can find in the @bin/<build variant>@ directory.
