# Installing Qt on Windows CE

Note: Qt for Windows CE has some requirements that are given in more detail in the Qt for Windows CE Requirements document.

1. Uncompress the files into the directory you want to install Qt into; e.g., `C:\Qt\4.5.1`.

   Note: The install path must not contain any spaces.

2. Environment variables

   In order to build and use Qt, the `PATH` environment variable needs to be extended:

        PATH               - to locate qmake, moc and other Qt tools

   This is done by adding `c:\Qt\4.5.1\bin` to the `PATH` variable.

   For newer versions of Windows, `PATH` can be extended through "Control Panel->System->Advanced->Environment variables" and for older versions by editing `c:\autoexec.bat`.

   Make sure the enviroment variables for your compiler are set. Visual Studio includes `vcvars32.bat` for that purpose - or simply use the "Visual Studio Command Prompt" from the Start menu.

3. Configuring Qt

   To configure Qt for Windows Mobile 5.0 for Pocket PC, type the following:

        C:
        cd \Qt\4.5.1
        configure -platform win32-msvc2005 -xplatform wincewm50pocket-msvc2005

   If you want to configure Qt for another platform or with other options, type `configure -help` to get a list of all available options. See the `README` file for the list of supported platforms.

4. Building Qt

   Now, to build Qt you first have to update your `PATH`, `INCLUDE` and `LIB` paths to point to the correct resources for your target platforms. For a default installation of the Windows Mobile 5.0 Pocket PC SDK, this is done with the following commands:

        set INCLUDE=C:\Program Files\Microsoft Visual Studio 8\VC\ce\include;C:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Include\Armv4i
        set LIB=C:\Program Files\Microsoft Visual Studio 8\VC\ce\lib\armv4i;C:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Lib\ARMV4I
        set PATH=C:\Program Files\Microsoft Visual Studio 8\VC\ce\bin\x86_arm;%PATH%

   We provide a convenience script for this purpose, called `setcepaths`. Simply type:

        setcepaths wincewm50pocket-msvc2005

   Then to build Qt type:

        nmake

5. That's all. Qt is now installed.

   To get started with Qt, you can check out the examples found in the `examples` directory of your Qt installation. The documentation can be found in `doc\html`.

   Remember: If you reconfigure Qt for a different platform, make sure you start with a new clean console to get rid of the platform dependent include directories.
