7-----------------
8.. index:: Microsoft Windows Installation

10This section details how you create an RTEMS development environment on
11Windows. The installation documented here is on `Windows 7 64bit Professional`.
12
13Developing on Windows
14~~~~~~~~~~~~~~~~~~~~~
15
16RTEMS supports Windows as a development host and the tools for most
17architectures are available. The RTEMS Project relies on the GNU tools for
18compilers and debuggers and we use the simulators that come with GDB and
19QEMU. The Windows support for these tools varies and the RTEMS Project is
20committed to helping the open source community improve the Windows
21experience. If something is not working or supported please email the
22:r:list:`users`.
23
24The RTEMS Project's Windows tools are native Windows executables giving the
25user the best possible experience on Windows. Native Windows programs use the
26standard Windows DLLs and paths. Integration with standard Windows integrated
27development tools such as editors is straight forward. POSIX emulation
28environments such as Cygwin and the MSYS2 shell have special executables that
29require a POSIX emulation DLL and these emulation DLLs add an extra layer of
30complexity as well as a performance over-head. The RTEMS Project uses these
31POSIX emulation shells to run configure scripts that come with various open
32source packages such as `gcc` so they form an important and valued part of the
33environment we describe here. The output of this procedure forms the tools you
34use during your application development and they do not depend the emulation
35DLLs.
36
37The performance of the compiler is as good as you can have on Windows and the
38performance compiling a single file will be similar to that on a host like
39Linux or FreeBSD given the same hardware. Building the tools from source is
40much slower on Windows because POSIX shells and related tools are used and the
41POSIX emulation overhead it much much slower than a native POSIX operating
42system like Linux and FreeBSD. This overhead is only during the building of the
43tools and the RTEMS kernel and if you use a suitable build system that is
44native to Windows your application development should be similar to other
45operating systems.
46
47Windows path length is limited and can cause problems when building the
48tools. The standard Windows API has a ``MAX_PATH`` length of 260
49characters. This can effect some of the tools used by RTEMS. It is recommended
50you keep the top level directories as short as possible when building the RTEMS
51tools and you also keep an eye on the path length when developing your
52application. The RTEMS built tools can handle much longer path lengths however
53some of the GNU tools such as those in the ``binutils`` package cannot. The
54release packages of the RSB are too big to build RTEMS so you need to change
55that path to build.
56
57The MSYS2 GNU ``make`` has problems when using the `jobs` option. The RSB
58defaults to automatically using as many cores as the host machine has. To get a
59successful build on Windows it is recommended you add the ``--jobs=none``
60option to all RSB build set commands.
61
62POSIX Support
63~~~~~~~~~~~~~
64
65Building the RTEMS compilers, debugger, the RTEMS kernel and a number of other
663rd party packages requires a POSIX environment. On Windows you can use Cygwin
67or MSYS2. This document focuses on MSYS2. It is smaller than Cygwin and comes
68with the Arch Linux package manager ``pacman``.
69
70MSYS2 provides MinGW64 support as well as a POSIX shell called MSYS2. The
71MinGW64 compiler and related tools produce 64bit native Windows
72executables. The shell is a standard Bourne shell and the MSYS2 environment is
73a stripped Cygwin shell with enough support to run the various ``configure``
74scripts needed to build the RTEMS tools and the RTEMS kernel.
75
76MSYS2 is built around the ``pacman`` packing tool. This makes MSYS2 a
77distribution and that is a welcome feature on Windows. You get a powerful tool
78to manage your development environment on Windows.
79
80Python
81~~~~~~
82
83We need Python to build the tools as the RSB is written in Python and we need
84suitable Python libraries to link to GDB as RTEMS makes use of GDB's Python
85support. This place specific demands on the Python we need installed and
86available and MSYS2 provides suitable Python versions we can use. You need to
87make sure you have the correct type and version of Python installed.
88
89We cannot use the Python executables created by the Python project (python.org)
90as they are built by Microsoft's C (MSC) compiler. Linking the MSC Python
91libraries with the MinGW64 executables is not easy and MSYS provided us with a
92simple solution so we do not support this.
93
94MSYS2 provides two types and versions of Python executables, MinGW and MSYS and
95Python version 2 and 3. For Windows we need the MinGW executable so we have
96suitables libraries and we have to have Python vrrsion 2 because on Windows GDB
97only builds with Python2.
98
99You also need to install the MSYS version of Python along with the MinGW64
100Python2 package. The MSYS Python is version 3 and the RSB can support version 2
101and 3 of Python and it helps handle some of the long paths building GCC can
102generate.
103
104Installing MSYS2
105~~~~~~~~~~~~~~~~
106
107MSYS2 is installed on a new machine using the MSYS2 installer found on
108https://msys2.github.io/. Please select the ``x86_64`` variant for 64bit
109support. Run the installer followin the 7 steps listed on the page.
110
111MSYS2 uses the ``pacman`` package manager. The Arch Linux project has detailed
112documentation on how to use ``pacman``. What is shown here is a just few
113examples of what you can do.
114
115Open a 64bit MSYS shell from the Start Menu:

361Building the Tools
362~~~~~~~~~~~~~~~~~~
363
364Create a workspace for RTEMS using the following shell command:
365
366.. sidebar:: *Creating Tool Archives*
367
368  Add ``--bset-tar-file`` to the ``sb-set-builder`` command line to create
369  tar files of the built package set.
370
371.. code-block:: shell
372
373   ~
374  $ mkdir -p /c/opt/rtems
375
376The ``/c`` path is an internal MSYS2 mount point of the ``C:`` drive. The
377command creates the RTEMS work space on the ``C:`` drive. If you wish to use
378another drive please subsitute ``/c`` with your drive letter.
379
380We build and install all RTEMS packages under the `prefix` we just created. Change to that
381directory and get a copy of the RSB:
382
383.. code-block:: shell
384
385   ~
386  $ cd /c/opt/rtems
387   /c/opt/rtems
388  $ git clone git://git.rtems.org/rtems-source-builder.git rsb

397   /c/opt/rtems
398  $ cd rsb
399
400We are building RTEMS 4.11 tools so select the *4.11* branch:
401
402.. code-block:: shell
403
404   /c/opt/rtems/rsb
405  $ git checkout 4.11
406  Branch 4.11 set up to track remote branch 4.11 from origin.
407  Switched to a new branch '4.11'
408   /c/opt/rtems/rsb
409  $
410
411Check the RSB has a valid environment:
412
413.. code-block:: shell
414
415   /c/opt/rtems/rsb
416  $ cd rtems
417   /c/opt/rtems/rsb/rtems
418  $ ../source-builder/sb-check
419  RTEMS Source Builder - Check, 4.11 (01ac76f2f90f)
420  Environment is ok
421   /c/opt/rtems/rsb/rtems
422  $
423
424To build a set of RTEMS tools for the Intel ``i386`` architecture:
425
426.. code-block:: shell

537Building the Kernel
538~~~~~~~~~~~~~~~~~~~
539
540We can now build the RTEMS kernel using the RTEMS tools we have just
541built. First we need to set the path to the tools:
542
543.. code-block:: shell
544
545   /c/opt/rtems
546  $ export PATH=/c/opt/rtems/4.11/bin:$PATH
547   /c/opt/rtems
548  $
549
550We currently build RTEMS from the git release branch for 4.11:
551
552.. code-block:: shell
553
554   /c/opt/rtems
555  $ mkdir kernel
556   /c/opt/rtems
557  $ cd kernel
558   /c/opt/rtems/kernel
559  $ git clone git://git.rtems.org/rtems.git rtems

573  Branch 4.11 set up to track remote branch 4.11 from origin.
574  Switched to a new branch '4.11'
575   /c/opt/rtems/kernel
576  $
577
578The kernel code cloned from git needs to be `bootstrapped`. Bootstrapping
579creates ``autoconf`` and ``automake`` generated files. To bootstrap we first
580clean away any files, then generate the pre-install header file lists and
581finally we generate the ``autoconf`` and ``automake`` files using the RSB's
582bootstrap tool.

646We will build the RTEMS kernel for the ``i386`` target and the ``pc686``
647BSP. You can check the available BSPs by running the ``rtems-bsps`` command
648found in the to directory of the RTEMS kernel source. We build the Board
649Support Package (BSP) outside the kernel source tree:

662Configure the RTEMS kernel to build ``pc686`` BSP for the ``i386`` target with
663netwoeking disabled, We will build the externel libBSD stack later:
