Installation¶

Obtaining the Source Code¶

Release Tarballs¶

Release source tarballs are available on the 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.

SCM¶

The Disorder source code is hosted in a Bazaar 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 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):

bzr co --lightweight bzr://bzr.squalllinesoftware.com/disorder

To clone the repository including the full history (suitable for Disorder development):

bzr branch bzr://bzr.squalllinesoftware.com/disorder

Prerequisites¶

Give the assumption that a somewhat sane build environment for C++ already exists on the build machine, the following third party things are required to build Disorder:

• Boost >= 1.49.0
• Eigen >= 3.0.5
• C++ version of the SEDRIS SRM >= 4.4.0 (optional but you will need some kind of sophisticated geospatial library)
• A Python interpreter (needed to use the 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.

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:

sudo apt-get install libboost-dev libboost-system-dev libboost-thread-dev libboost-date-time-dev libeigen3-dev

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

sudo apt-get install python

Sabayon Linux¶

Pat yourself on the back for using a good operating system. To install boost via the entropy package system:

sudo equo install boost

As of 2/22/2013, the Eigen verison in entropy is a bit outdated (3.0.6). You can use it, but you probably should download the latest version from Eigen which doesn't require any compilation. Just extract the content of the archive somewhere and remember to tell Disorder where to find it with --eigen-root=<put actual path to eigen root here> during the configuration step.

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

sudo equo install python

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.

Linux¶

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

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

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

./waf configure --sedris-srm-root=/opt/sedris/srm

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

'configure' finished successfully (25.518s)

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.

Clang++¶

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

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

For example:

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

Windows¶

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

The easiest way to configure Disorder on Windows is to use a modified version of the provided batch file to tell Disorder where your prerequisites live. Copy the template from tools/windows/configure.bat to the root of the Disorder tree.

This file contains some variables near the middle that must be set according to your system configuration. An example is provided in the template for guidance.

Once you are finished editing configure.bat, it's time to execute it. From the command line:

configure.bat

If everything is successful, you should get something that looks like this:

'configure' finished successfully (31.262s)

If you don't see that last line that says 'configure' finished successfully, then something is screwed up and it needs to be fixed. Fix it and try again.

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.

Linux¶

On Linux, to build the Disorder debug variant:

./waf build_debug

Windows¶

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

python.exe waf build_optimized

Building Against the Disorder Library¶

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.

Linking¶

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