(ReactOS Wiki) Building Modules

There are many applications, tests, and extra subsystems in the ReactOS SVN. Most are not included by default and require a few easy steps.

== Technical Information ==

In "reactos/modules" or "reactos\modules", depending on whether you're on a UNIX or Windows system, are two files, ''empty.rbuild'' and ''directory.rbuild''. The Build system will read the ''directory.rbuild'' file and look if the subfolders named in this file exist.

If a folder exists, the Build System will process its ''directory.rbuild'' file. Otherwise it will fall back to the ''empty.rbuild'' file.

== Integrating a module ==

If you want to integrate a module into the build, it's the easiest to copy the appropriate folder into the "modules" directory.

If you already downloaded a module into another directory and want to keep it there (e.g. for updating it via SVN), you can also create a symbolic link to that directory. This also saves disk space.

On Windows, a symbolic link can be created on NTFS partitions with the [http://www.microsoft.com/technet/sysinternals/FileAndDisk/Junction.mspx Junction] utility. After you installed this utility, open a Command Prompt, jump to the "modules" directory and execute the following command:

junction rosapps X:\reactos\rosapps

In this case, I assume that you want to create a symbolic link to the "rosapps" module, which is located at X:\reactos\rosapps.

Under Unix-based operating systems such as Linux, you can use the following command to create a symbolic link:

ln -s /home/user/reactos/rosapps rosapps

This example assumes that you want to create a symbolic link to the "rosapps" module, which is located at /home/user/reactos/rosapps.

== Modules ==

We currently have the following modules in the SVN Tree:

* rosapps - Various non-core applications, like additional screensavers

* rostests - Various tests, including ReactOS specific tests and the Wine test suite
