Development Environment Setup on Windows
########################################

This section describes how to configure your development environment and
to build Zephyr applications in a Microsoft Windows environment.

This guide was tested by compiling and running the Zephyr's sample
applications on Windows version 8.1 (and should work with Windows 10 as well).

Update Your Operating System
****************************

Before proceeding with the build, ensure that you are running your
Windows system with the latest updates installed.

Installing Requirements and Dependencies
****************************************

To install the software components required to build Zephyr applications on
Windows, you will need to build or install a toolchain:

1. Install :program:`GIT`. Go to `GIT Download`_ to obtain the latest copy of
   the software (2.12.0).  Install into the :file:`C:\\Git` folder and use the
   default configuration options for the rest.

2. Install :program:`Python 2.7`. Go to `Python Download`_ to obtain the
   software (version 2.7.13) and use the default installation options.

3. Install :program:`MinGW`. MinGW is the minimalist GNU development environment
   for native Windows applications. The Zephyr build system will execute on top
   of this tool set.  Visit the site `MinGW Home`_ and install the
   following packages with their installer `mingw-get-setup.exe` (you'll need
   to open the "All Packages" tab to enable installing the msys packages listed
   here):

   * mingw-developer-toolkit
   * mingw32-base
   * msys-base
   * msys-binutils
   * msys-console
   * msys-w32api

4. Launch the `MSYS console` from a cmd window. The installer does not create
   shortcuts for you so you'll need to run the script
   in :file:`C:\\MinGW\\msys\\1.0\\msys.bat.`

5. The Zephyr build process has a dependency on the Pthread and GNU regex
   libraries.  Msys provides its own GNU library implementation that can be
   downloaded from the MinGW and Msys official repository:
   `MinGW Repository`_ with the following commands:

   .. code-block:: console

      mingw-get update
      mingw-get install libpthread msys-libregex-dev --all-related


   When done, move libregex files (``libregex.a``, ``libregex.dll.a``,
   ``libregex.la``)
   from ``C:\Git\mingw32\msys\1.0\lib`` to ``C:\Git\mingw32\lib``

6. We need to edit :file:`/etc/fstab` to create an entry mapping from the Win32
   path ``c:/mingw`` to the mount point ``/mingw``
   The easiest way to do this is just copy the file :file:`fstab.sample` as
   :file:`fstab` and ``cat /etc/fstab`` to confirm that the mapping was added.


7. The build system should be able to work with any toolchain installed in your
   system. For instance, the Zephyr build system was tested using the mingw
   MSYS console (as described below) with the toolchain
   provided with the ISSM 2016 (Intel System Studio for Microcontrollers)
   installation.  Install ISSM from the Intel Developer Zone:
   `ISSM 2016 Download`_

   .. note::

      The ISSM toolset only supports development for Intel® Quark™
      Microcontrollers, for example, the Arduino 101 board.  (Check out the
      "Zephyr Development Environment
      Setup" in this `Getting Started on Arduino 101 with ISSM`_ document.)
      Also, additional setup is required to use the ISSM GUI for
      development.

8. From within the MSYS console, clone a copy of the Zephyr source into your
   home directory using Git:

   .. code-block:: console

      cd ~
      git clone https://gerrit.zephyrproject.org/r/zephyr

9. Also within the MSYS console, set up environment variables for installed
   tools and for the Zephyr environment (using the provided shell script):

   .. code-block:: console

      export PATH=$PATH:/c/python27/
      export MINGW_DIR=/c/mingw
      export ZEPHYR_GCC_VARIANT=issm
      export ISSM_INSTALLATION_PATH=C:/IntelSWTools/ISSM_2016.1.067
      unset ZEPHYR_SDK_INSTALL_DIR
      source ~/zephyr/zephyr-env.sh

10. Finally, you can try building the :ref:`hello_world` sample to check things
    out.  In this example, we'll build the hello_world sample for the Arduino
    101 board:

    .. code-block:: console

       cd $ZEPHYR_BASE/samples/hello_world
       make board=arduino_101

    This should check that all the tools and toolchain are setup correctly for
    your own Zephyr development.
