# Chapter 1. Introduction

The eCosTM Configuration Tool offers Windows users a graphical user interface with which they can select an eCos configuration.

If you"re working in UNIX, see Chapter 7 for information on using the eCos command line tools.

With the Configuration Tool you can construct a configuration and save it in the form of a build tree containing header files. These header files can be used both for constructing a library to which user applications can be linked, and for compiling user code. See Chapter 4 for a discussion of the component repository and the other directory trees.

The Configuration Tool is installed together with the source to the eCos kernel and the other packages. A step-by-step walk through the Configuration Tool is given in Getting Started with eCos.

# Invoking the Configuration Tool

There are two ways to invoke the Configuration Tool:

- Open it in the desktop explorer or program group set up at install time (by default Start -> Programs -> Cygnus eCos -> Configuration Tool).

- Type (at the command prompt or in the Start menu"s Run item) <directoryname>\ConfigTool.exe where `<directoryname>` is the full path of the directory in which you installed the Configuration Tool.

When invoked by typing the command, the Configuration Tool accepts a build tree as parameter; for example:

    C:\> ConfigTool.exe c:\ecos-work\build-1

This instructs the Configuration Tool to open the named build tree rather than starting with a default configuration. One useful application of this feature is to create Configuration Tool shortcuts that include build tree arguments in their command lines.

Once the Configuration Tool is running, you can also open a build tree by dragging and dropping a folder into the tool window.
