# Configuration Options for Qt

This page gives a brief description of the different options available when building Qt using the `configure` script or `configure.exe` binary. To build Qt using the default options, just call configure from the command line as shown below.

When building on Linux, Mac OS X and Unix platforms:

`./configure`

On Windows, run the corresponding executable:

`.\configure.exe`

If you would like to customize your build, please use the options listed in the following tables. To see the full list of options, invoke the configure tool with the `-help` command line option.
