Development

If you'd like to know what's under the hood you are welcome to inspect UltraDefrag sources. You can either use online svn browser or download sources from SourceForge. Alternatively you can setup an SVN client (for instance TortoiseSVN) and check sources out from their base address.

Essential parts of UltraDefrag are written in four programming languages:

UltraDefrag core libraries are written in pure C for compatibility with Windows boot environment where only bare ntdll interfaces are available. Both graphical and command line tools are written in C++ on top of wxWidgets library which helps to keep things simple. For configuration purposes and reports convertion the program uses Lua scripting language. UltraDefrag installers are written in NSIS.

Compilation

To build the program install the following software:

To build 64-bit packages install also Microsoft Windows SDK v7.1.

To configure build environment follow these steps:

:: edit the main configuration file
edit setvars.cmd
:: patch the installed software
patch-tools
:: build wxWidgets using all the compilers
:: involved in development
wxbuild --use-mingw
wxbuild --use-winsdk

To build UltraDefrag use the following commands:

:: build the program using defaults
build
:: show all available options
build --help
:: use predefined build actions
build-menu

If you need an IDE for development install Code::Blocks as well. To launch it in correct environment type:

start-CodeBlocks

If you'd like to know how the build process works inspect .cmd files - they contain the complete information.
