The installation documented here is on `Windows 7 64bit Professional`. -Developing on Windows -~~~~~~~~~~~~~~~~~~~~~ - -RTEMS supports Windows as a development host and the tools for most -architectures are available. The RTEMS Project relies on the GNU tools for -compilers and debuggers and we use the simulators that come with GDB and -QEMU. The Windows support for these tools varies and the RTEMS Project is -committed to helping the open source community improve the Windows -experience. If something is not working or supported please email the -:r:list:`users`. - -The RTEMS Project's Windows tools are native Windows executables giving the -user the best possible experience on Windows. Native Windows programs use the -standard Windows DLLs and paths. Integration with standard Windows integrated -development tools such as editors is straight forward. POSIX emulation -environments such as Cygwin and the MSYS2 shell have special executables that -require a POSIX emulation DLL and these emulation DLLs add an extra layer of -complexity as well as a performance over-head. The RTEMS Project uses these -POSIX emulation shells to run configure scripts that come with various open -source packages such as `gcc` so they form an important and valued part of the -environment we describe here. The output of this procedure forms the tools you -use during your application development and they do not depend the emulation -DLLs. - -The performance of the compiler is as good as you can have on Windows and the -performance compiling a single file will be similar to that on a host like -Linux or FreeBSD given the same hardware. Building the tools from source is -much slower on Windows because POSIX shells and related tools are used and the -POSIX emulation overhead it much much slower than a native POSIX operating -system like Linux and FreeBSD. This overhead is only during the building of the -tools and the RTEMS kernel and if you use a suitable build system that is -native to Windows your application development should be similar to other -operating systems. - -Windows path length is limited and can cause problems when building the -tools. The standard Windows API has a ``MAX_PATH`` length of 260 -characters. This can effect some of the tools used by RTEMS. It is recommended -you keep the top level directories as short as possible when building the RTEMS -tools and you also keep an eye on the path length when developing your -application. The RTEMS built tools can handle much longer path lengths however -some of the GNU tools such as those in the ``binutils`` package cannot. The -release packages of the RSB are too big to build RTEMS so you need to change -that path to build. - -The MSYS2 GNU ``make`` has problems when using the `jobs` option. The RSB -defaults to automatically using as many cores as the host machine has. To get a -successful build on Windows it is recommended you add the ``--jobs=none`` -option to all RSB build set commands. - -POSIX Support -~~~~~~~~~~~~~ - -Building the RTEMS compilers, debugger, the RTEMS kernel and a number of other -3rd party packages requires a POSIX environment. On Windows you can use Cygwin -or MSYS2. This document focuses on MSYS2. It is smaller than Cygwin and comes -with the Arch Linux package manager ``pacman``. - -MSYS2 provides MinGW64 support as well as a POSIX shell called MSYS2. The -MinGW64 compiler and related tools produce 64bit native Windows -executables. The shell is a standard Bourne shell and the MSYS2 environment is -a stripped Cygwin shell with enough support to run the various ``configure`` -scripts needed to build the RTEMS tools and the RTEMS kernel. - -MSYS2 is built around the ``pacman`` packing tool. This makes MSYS2 a -distribution and that is a welcome feature on Windows. You get a powerful tool -to manage your development environment on Windows. - -Python -~~~~~~ - -We need Python to build the tools as the RSB is written in Python and we need -suitable Python libraries to link to GDB as RTEMS makes use of GDB's Python -support. This place specific demands on the Python we need installed and -available and MSYS2 provides suitable Python versions we can use. You need to -make sure you have the correct type and version of Python installed. - -We cannot use the Python executables created by the Python project (python.org) -as they are built by Microsoft's C (MSC) compiler. Linking the MSC Python -libraries with the MinGW64 executables is not easy and MSYS provided us with a -simple solution so we do not support this. - -MSYS2 provides two types and versions of Python executables, MinGW and MSYS and -Python version 2 and 3. For Windows we need the MinGW executable so we have -suitables libraries and we have to have Python vrrsion 2 because on Windows GDB -only builds with Python2. - -You also need to install the MSYS version of Python along with the MinGW64 -Python2 package. The MSYS Python is version 3 and the RSB can support version 2 -and 3 of Python and it helps handle some of the long paths building GCC can -generate. - -Installing MSYS2 -~~~~~~~~~~~~~~~~ - -MSYS2 is installed on a new machine using the MSYS2 installer found on -https://msys2.github.io/. Please select the ``x86_64`` variant for 64bit -support. Run the installer followin the 7 steps listed on the page. - -MSYS2 uses the ``pacman`` package manager. The Arch Linux project has detailed -documentation on how to use ``pacman``. What is shown here is a just few -examples of what you can do. - -Open a 64bit MSYS shell from the Start Menu: - -.. figure:: msys2-minw64-start-menu.png - :width: 50% - :align: center - :alt: MSYS2 64bit Shell Start Menu - -The packages we require are: - - * python - * mingw-w64-x86_64-python2 - * mingw-w64-x86_64-gcc - * git - * bison - * cvs - * diffutils - * make - * patch - * tar - * texinfo - * unzip - -.. note:: - - The actual output provided may vary due to changes in the dependent packages - or newer package versions. - -Install the packages using ``pacman``: +Please see :ref:`microsoft-windows` before continuing. -.. code-block:: shell - - ~ - $ pacman -S python mingw-w64-x86_64-python2 mingw-w64-x86_64-gcc \ - > bison cvs diffutils git make patch tar texinfo unzip - resolving dependencies... - looking for conflicting packages... - - Packages (74) db-5.3.28-2 expat-2.1.0-2 gdbm-1.11-3 heimdal-1.5.3-8 - libgdbm-1.11-3 mingw-w64-x86_64-binutils-2.26-21 - mingw-w64-x86_64-bzip2-1.0.6-5 - mingw-w64-x86_64-ca-certificates-20150426-2 - mingw-w64-x86_64-crt-git-5.0.0.4627.03684c4-1 - mingw-w64-x86_64-expat-2.1.0-6 mingw-w64-x86_64-gcc-libs-5.3.0-2 - mingw-w64-x86_64-gdbm-1.11-3 mingw-w64-x86_64-gettext-0.19.6-2 - mingw-w64-x86_64-gmp-6.1.0-1 - mingw-w64-x86_64-headers-git-5.0.0.4627.53be55d-1 - mingw-w64-x86_64-isl-0.15-1 mingw-w64-x86_64-libffi-3.2.1-3 - mingw-w64-x86_64-libiconv-1.14-5 - mingw-w64-x86_64-libsystre-1.0.1-2 - mingw-w64-x86_64-libtasn1-4.7-1 - mingw-w64-x86_64-libtre-git-r122.c2f5d13-4 - mingw-w64-x86_64-libwinpthread-git-5.0.0.4573.628fdbf-1 - mingw-w64-x86_64-mpc-1.0.3-2 mingw-w64-x86_64-mpfr-3.1.3.p0-2 - mingw-w64-x86_64-ncurses-6.0.20160220-2 - mingw-w64-x86_64-openssl-1.0.2.g-1 - mingw-w64-x86_64-p11-kit-0.23.1-3 - mingw-w64-x86_64-readline-6.3.008-1 mingw-w64-x86_64-tcl-8.6.5-1 - mingw-w64-x86_64-termcap-1.3.1-2 mingw-w64-x86_64-tk-8.6.5-1 - mingw-w64-x86_64-windows-default-manifest-6.4-2 - mingw-w64-x86_64-winpthreads-git-5.0.0.4573.628fdbf-1 - mingw-w64-x86_64-zlib-1.2.8-9 openssh-7.1p2-1 perl-5.22.0-2 - perl-Authen-SASL-2.16-2 perl-Convert-BinHex-1.123-2 - perl-Encode-Locale-1.04-1 perl-Error-0.17024-1 - perl-File-Listing-6.04-2 perl-HTML-Parser-3.71-3 - perl-HTML-Tagset-3.20-2 perl-HTTP-Cookies-6.01-2 - perl-HTTP-Daemon-6.01-2 perl-HTTP-Date-6.02-2 - perl-HTTP-Message-6.06-2 perl-HTTP-Negotiate-6.01-2 - perl-IO-Socket-SSL-2.016-1 perl-IO-stringy-2.111-1 - perl-LWP-MediaTypes-6.02-2 perl-MIME-tools-5.506-1 - perl-MailTools-2.14-1 perl-Net-HTTP-6.09-1 - perl-Net-SMTP-SSL-1.02-1 perl-Net-SSLeay-1.70-1 - perl-TermReadKey-2.33-1 perl-TimeDate-2.30-2 perl-URI-1.68-1 - perl-WWW-RobotRules-6.02-2 perl-libwww-6.13-1 vim-7.4.1468-1 - bison-3.0.4-1 cvs-1.11.23-2 diffutils-3.3-3 git-2.7.2-1 - make-4.1-4 mingw-w64-x86_64-gcc-5.3.0-2 - mingw-w64-x86_64-python2-2.7.11-4 patch-2.7.5-1 python-3.4.3-3 - tar-1.28-3 texinfo-6.0-1 unzip-6.0-2 - - Total Download Size: 114.10 MiB - Total Installed Size: 689.61 MiB - - :: Proceed with installation?
