Editing Octave for Microsoft Windows (outdated) (section)

=Older version instructions=
''Note that the instructions below may contain outdated links or instructions that are no longer relevant to current versions''

==Older MXE builds== 

===Octave-4.4.1===
In Octave 4.4.1, the {{Path|post_install.bat}} file was not available for the 7z/Zip archives.  After unzipping the package and creating shortcuts, the user is required to first run the {{Path|fc_update.bat}} file to rebuild the font cache and reduce first time plotting delays, and then run 'pkg rebuild' from the Octave command line to make the pre-installed packages available to the system.


===Octave-4.4.0===
In addition to the post-install instructions above for Octave 4.4.1, in Octave 4.4.0 the shortcuts start the command line interface, not the graphical user interface, by default. The user needs to add --force-gui to any manual shortcuts to start Octave with the GUI. (Right-click on the shortcut, select Properties, and add --force-gui to the end of the Target field.) Later versions reverted back to the previous behavior where graphical user interface runs by default.

===Octave-4.2.0-4.2.2===

The instructions for Octave 4.2.0 - 4.2.2 are the same as for Octave 4.4.0. However, note that version 4.2.0 has a bug that prevents it from automatically retrieving packages from the [https://octave.sourceforge.io/packages.php Octave Forge website] for installation or updates. Manual package installation is necessary with this version to update or install new packages on Windows.

To manually install a new or updated package version, the package file can be downloaded from the [https://octave.sourceforge.io/packages.php Octave Forge website] to the working directory and can be installed using:

   >> pkg install package_file_name.tar.gz

===Octave-4.0.3===

The easiest way to install GNU Octave on Microsoft Windows is using [http://hg.octave.org/mxe-octave/ MXE] builds. For the current 4.0. release installers and zip archived packages can be found at [https://ftp.gnu.org/gnu/octave/windows/ ftp.gnu.org/gnu/octave/windows/]. Unofficial 64 bit binary is available at "[http://www.tatsuromatsuoka.com/octave/Eng/Win/ File list of Octave for Windows]". 

Known issue specific to windows version 4.0
#Both cli and gui cannot handle path name of which contains non-ascii characters. (For 3.8, cli can handle non-ascii code if codepage is properly set to the machine locale)
#nan package cannot be installed by "pkg install" commands. Workaround is to execute "setenv CC gcc" before "pkg install".

Known issue of octave starup
# octave sometimes will fail to startup because of internal troubles. On such occasion, please try to delete .config\octave folder by which USERPROFILE environmental variable points. (One of the way to see value of USERPROFILE, startup command prompt and type "set") 

====Packages====
Pre-built Octave Forge packages are prepared for official release. If you installed Octave 4.0.3 using the executable installer you can confirm the package list by typing the command below from the Octave command prompt:

  >> pkg list

If you instead installed Octave from the .zip archive, you need to first rebuild the package list on your local machine. (The command above will produce a blank output.) Do this by typing the following command:

  >> pkg rebuild

Other packages can be installed by

   >> pkg install -forge <package name>

For 64 bit binary distributed from the unofficial site, pre-built package are not prepared.
Please follow the instruction on the distribution page.

====gnuplot====
Current octave for windows ships a not full featured gnuplot. Therefore you cannot use the full features of gnuplot graphics toolkit  
(e.g. cannot use cairo based devise like "-dpdfcairo"). If you want use it, please use the following instruction

Download and install gnuplot if you do not have it. You can find the windows installer in the "[https://sourceforge.net/projects/gnuplot/files/gnuplot/ gnuplot web site for Files section]" The latest version is 5.0.3.

We can find path of USERPROFILE directory by 
  >> getenv USERPROFILE
make an .octaverc file in USERPROFILE directory by your favorite text editor and set gnuplot_binary e.g.

  gnuplot_binary 'C:\Program Files (x86)\gnuplot\bin\gnuplot.exe'

Please do not forget to quote the path name by single quote (') if name of which has (a) white space(s).
gnuplot ver. 5 supports windows, wxt and qt terminal. On octave, windows terminal is default.
If you want change it to wxt terminal, execute

 >> setenv GNUTERM wxt

You can of course describe it in .octaverc.

==Older MinGW ports==

===Octave-4.0.0 ===

The easiest way to install GNU Octave on Microsoft Windows is using [http://hg.octave.org/mxe-octave/ MXE] builds. For the current 4.0.0 release installers can be found at [https://ftp.gnu.org/gnu/octave/windows/ ftp.gnu.org].

Known issues specific to windows version 4.0.0.
#Both cli and gui cannot handle path name of which contains non-ascii characters. (For 3.8, cli can handle non-ascii code if codepage is properly set to the machine locale)

====Packages====
Pre-build octave-forge packages are not prepared from octave-3.8 or later for windows. You can install some octave-forge packages using archived sources and build script. However, small flaws exist in current octave-4.0.0_0 distribution. Before install, correct version number of general and signal packages version to 2.0.0 and 1.3.2, respectively and comment out install io package as "#try_install io-2.2.7.tar.gz" in C:\octave\octave-4.0.0\src\build_packages.m". Then execute

    >> cd C:\octave\octave-4.0.0\src
    >> build_packages
    >> pkg install -forge io

Other octave-forge packages may be installed by

   >> pkg install -forge (package name)

For detailed instruction of installing Octave-Forge packages is shown at [http://wiki.octave.org/Octave-Forge Octave-Forge]

===Octave-3.8.2 ===
The site that provide previous version of octave for windows of ver. 3.8.2 (unofficial build using mxe-octave) is closed.
A mirrored binary can be downloaded at [http://www.tatsuromatsuoka.com/octave/Eng/Win/ File list of Octave for Windows]  

If you got any problems while running Windows 8 or libstdc++-6.dll errors, try this octave-gui.bat file and place it into your Octave folder (e.g. `C:/octave/octave-3.8.2`).

    @echo off
    set PATH=%CD%\bin\
    start octave --force-gui -i --line-editing
    exit

===Octave-3.6.4-mingw + octaveforge pkgs===

For build instructions before octave-3.8 see [[Octave_for_MinGW]] or the Octave-Forge repository [http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/].

====Manual installation instructions====
#Create an installation directory of which doesn't have space chars (i.e. C:\Octave\Octave3.6.4_gcc4.6.2\). This directory is referred hereafter as <your_install_dir>.
#Extract the complete directories tree from Octave3.6.4_gcc4.6.2_20130329.7z to the installation directory  keeping the original directory structure as in the archive (you can use 7-zip tool from http://www.7-zip.org/).  Note that the archive contains Octave3.6.4_gcc4.6.2 folder, so you want to extract to the *parent* of <your_install_dir>.
#Copy octave3.6.4_gcc4.6.2.lnk to any convenient location and edit its properties respectively to point to <your_install_dir>\bin\octave.exe and <your_install_dir>\doc\octave\icons\octave-logo.ico as an icon
#:Note for windows 8 users: As a workaround for a gnulib windows 8 compatibility bug, add command line switches ' -i --line-editing' to the octave.exe shortcut (i.e. <octave-dir>\bin\octave.exe -i --line-editing)
#Copy octave3.6.4_gcc4.6.2_docs.lnk to any convenient location and edit its properties respectively to point to <your_install_dir>\doc\octave and <your_install_dir>\doc\octave\icons\octave-logo.ico as an icon.
#:At this point you can:
#: a. Launch and use octave by double-clicking the copied octave3.6.4_gcc4.6.2.lnk
#: b. Access and browse the documentation files by double-clicking the copied octave3.6.4_gcc4.6.2_docs.lnk
#Optional libblas dll replacement for optimizing the linear algebra subroutines for your CPU:
#:* The default configuration should automatically detect your cpu architecture and select an appropriately tuned library. 
#:* In case the default library is not properly functioning on the actual cpu, or you wish to explore the performance with another library, you can manually replace the default one by performing the following procedures (where libblas.dll.<libblas_source> should be replaced with the full name of the desired library from the list below these instructions):
#:*# Exit octave
#:*# Delete <your_install_dir>\bin\libblas.dll
#:*# Make a copy of the desired <your_install_dir>\bin\libblas.dll.<libblas_source>
#:*# Rename the copy of the desired <your_install_dir>\bin\libblas.dll.<libblas_source> to libblas.dll
#:*  The following is a list of the available libblas.dll.<libblas_source> options:
#:*# libblas.dll.ref - reference blas implementation, very slow but most stable
#:*# libblas.dll.OpenBLAS-v2.6.0-0-54e7b37_dynamicarch_nt4 - Openblas based, up to 4 threads, detects cpu architecture and selects respective lib
#:*# libblas.dll.OpenBLAS-v2.6.0-0-54e7b37_nehalem_nt4 - Openblas based, up to 4 threads, tuned for nehalem cpu architecture
#:*# libblas.dll.OpenBLAS-v2.6.0-0-54e7b37_core2_nt4 - Openblas based, up to 4 threads, tuned for core2 cpu architecture
#:*# libblas.dll.OpenBLAS-v2.6.0-0-54e7b37_sandybridge_nt4 - Openblas based, up to 4 threads, tuned for sandybridge cpu architecture
#:*# libblas.dll.OpenBLAS-v2.6.0-0-54e7b37_atom_nt4 - Openblas based, up to 4 threads, tuned for atom cpu architecture
#:*# libblas.dll.altas-3.8.4_ht-pentium - ATLAS based libblass, tuned for older ht-pentium (compiled by Tatsuro Matsuka)
#:*# libblas.dll.altas-3.8.4_corei5 - ATLAS based libblass, tuned for older core i5 cpu (compiled by Tatsuro Matsuka)

====Manual installation instructions for the Octave-forge packages====
#Extract the complete directories tree from Octave3.6.4_gcc4.6.2_pkgs_20130331.7z to the installation directory (<your_install_dir>) keeping the original directory structure as in the archive (you can use 7zip tool from http://www.7-zip.org/).
#In order to update octave_packages database with your installation tree and auto-load most packages (excluding 'ad' and 'windows' which may crash octave when loaded and 'clear all' is executed), launch Octave and execute the following five rebuild commands from the octave console:
    pkg rebuild -auto
    pkg rebuild -noauto ad % may crash octave when loaded and 'clear all' is executed
    pkg rebuild -noauto nan % shadows many statistics functions
    pkg rebuild -noauto gsl % shadows some core functions
    pkg rebuild -auto java
#: Last pkg rebuild command is required in order for the java pkg entry to be moved to the top of <your_install_dir>\share\octave\octave_packages db file - thus java pkg is loaded before io pkg is loaded, and io pkg related jars are added to java class path.
#You can optionally adjust your installed packages status per your specific needs and usage by executing  the following commands:
: a. To interactively load or unload a package
 pkg load <pkg_name>
: or
 pkg unload <pkg_name>
: b. To disable auto-load for specific pkg <pkg_name>
 pkg rebuild -noauto <pkg_name>
: c. To enable auto-load for specific pkg <pkg_name>
 pkg rebuild -auto <pkg_name>
: d. To completely uninstall a package
 pkg uninstall <pkg_name>

====Optional installation of Notepad++ as an editor (recommended)====
#Download recent Notepad++ installation package from http://notepad-plus-plus.org/ and install it on your system.
#Edit <your_install_dir>\share\octave\site\m\startup\octaverc and un-comment the line which sets octave default editor:
 EDITOR('C:\Program Files\Notepad++\notepad++.exe');
 edit ("editor", sprintf ("%s %%s", EDITOR ()))
 edit mode async
: Note: win64 users may use the w32 programs directory:
 EDITOR('C:\Program Files (x86)\Notepad++\notepad++.exe');
: Note: You may adjust the above line for the location of notepad++.exe as installed on your system.

====Troubleshooting====
Upon launching, some warnings may be displayed. These warnings can be ignored.
*Following warnings are about missing external tools which may reduce some of the functions of some packages. These external tools are not provided by the 7z archives in sourceforge. 
 warning: gmsh does not seem to be present some functionalities will be disabled 
 warning: dx does not seem to be present some functionalities will be disabled 
*Following warning is about fstat function of the statistics package that overloads the old (to be deprecated) fstat function of octave-3.6.4 
 warning: function C:\Octave\3.6.4_gcc-4.6.2\share\octave\packages\statistics-1.2.0\fstat.m shadows a core library function

====Manual installation instructions for the Octave-forge packages====
#Extract the complete directories tree from Octave3.6.1_gcc4.6.2_pkgs_20120303.7z to the installation directory (<your_install_dir>) keeping the original directory structure as in the archive (you can use 7zip tool from http://www.7-zip.org/).
#In order to update octave_packages database with your installation tree and auto-load most packages (excluding 'ad' and 'windows' which may crash octave when loaded and 'clear all' is executed), launch Octave and execute the following 3 rebuild commands from the octave console:
    pkg rebuild -auto
    pkg rebuild -noauto ad windows
    pkg rebuild -noauto nan % shadows many statistics functions
    pkg rebuild -noauto gsl % shadows some core functions
    pkg rebuild -auto java
#: Last pkg rebuild command is required in order for the java pkg entry to be moved to the top of <your_install_dir>\share\octave\octave_packages db file - thus java pkg is loaded before io pkg is loaded, and io pkg related jars are added to java class path.
#You can optionally adjust your installed packages status per your specific needs and usage by executing  the following commands:
: a. To interactively load or unload a package
 pkg load <pkg_name>
: or
 pkg unload <pkg_name>
: b. To disable auto-load for specific pkg <pkg_name>
 pkg rebuild -noauto <pkg_name>
: c. To enable auto-load for specific pkg <pkg_name>
 pkg rebuild -auto <pkg_name>
: d. To completely uninstall a package
 pkg uninstall <pkg_name>
====Optional installation of Notepad++ as an editor (recommended)====
#Download recent Notepad++ installation package from http://notepad-plus-plus.org/ and install it on your system.
#Edit <your_install_dir>\share\octave\site\m\startup\octaverc and un-comment the line which sets octave default editor:
 EDITOR('C:\Program Files\Notepad++\notepad++.exe');
 edit ("editor", sprintf ("%s %%s", EDITOR ()))
 edit mode async
: Note: You may adjust the above line for the location of notepad++.exe as installed on your system.

====Troubleshooting====
Upon launching, some warnings may be displayed. These warnings can be ignored.
*Following warnings are about missing external tools which may reduce some of the functions of some packages. These external tools are not provided by the 7z archives in sourceforge. 
 warning: gmsh does not seem to be present some functionalities will be disabled 
 warning: dx does not seem to be present some functionalities will be disabled 
*Following warning is about fstat function of the statistics package that overloads the old (to be deprecated) fstat function of octave-3.6.1 
 warning: function C:\Octave\3.6.1_gcc-4.6.2\share\octave\packages\statistics-1.1.0\fstat.m shadows a core library function

====Notes====
*Although there are some remaining known issues, some bugs reported to the octave-3.2.3 have been corrected. In addition, useful octave-forge packages are added (Java, Jhandles, ....). Please see [http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.2.4%20for%20Windows%20MinGW32%20Installer/RELEASE_NOTES-3.2.4.txt/download RELEASE_NOTES.txt] for details:  
*Default Octave install folder changed to e.g. <code>C:\Octave\3.2.4_gcc-4.4.0\</code>. 
*:If you have installed octave in a folder where the path name has whitespace, for example, <code>C:\Program Files\</code>, 'pkg install (package name)' command '''will fail''': See http://sourceforge.net/mailarchive/message.php?msg_name=4A1AF9EF.1000005@hotmail.com for details

'''Additional important topics found after the release:'''
*It is reported that the oct2mat octave-forge package affects plot related commands. The purpose of the package is to convert m-file into matlab-compatible coding style. Please see the documentation of the octave-forge (oct2mat - freetb4matlab) from http://octave.sourceforge.net/functions_by_package.php) 
**Report for this problem: http://old.nabble.com/Re:-Octave-3.2.4-mingw32-available-p28053703.html 
**Explanation of the problem: http://old.nabble.com/Re:-Octave-3.2.4-mingw32-available-p28090303.html 
**Realistic solution at this moment, do not install the oct2mat package when you install octave with octave-forge packages if you do not use this package. Another solution is to execute
      pkg rebuild -noauto oct2mat
::at the octave prompt and then restart octave. The operation results in the oct2mat package not to be auto-loaded in startup. When you want to use oct2mat, execute 
      pkg load oct2mat 
*The plot octave-forge package still have ginput code although the ginput function is now merge into octave itself. Therefore conflict occur if the plot package is installed. To avoid this problem, rename 'ginput.m' in the folder <code>..\Octave\3.2.4_gcc-4.4.0\share\octave\packages\plot-1.0.7</code>, for example ginput.ob.m. In some computers which has one core CPU, response of ginput is very slow. In the case, modify '__gnuplot_ginput__.m' according to the following thread. http://old.nabble.com/ginput-on-Octave-3.2.4-mingw32-to28093888.html 
*From gnuplot-4.4.0, the default terminal of gnuplot for windows is the wxt terminal. Some users may set the GNUTERM environmental variable for the windows terminal being default. The gnuplot for windows allows to set GNUTERM to 'win' (abbreviated form) but octave does not recognize the abbreviated form for terminal name. If one would like set GNUTERM to windows terminal, one should specify it as 'windows' (full form) but not 'win' (abbreviated form). In detail see the following thread: http://old.nabble.com/flicking-problem-again-Octave-3.2.4-mingw32-td28038688.html

==Older Octave versions with Visual Studio==

Octave binaries compiled with Microsoft Visual Studio are available for download from [http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.4%20for%20Windows%20Microsoft%20Visual%20Studio/ Octave-Forge site]. These binaries come in the form of an easy-to-use installer (created with [http://nsis.sourceforge.net/ NSIS]) and are provided in 2 flavors: pre-compiled version for Visual Studio 2008 and for Visual Studio 2010.

These binaries do not include the Microsoft Visual C++ compiler. This must be installed separately, but is only required if you plan to compile and link source code against the pre-compiled octave release. If the Visual C++ compiler is not present on the target system, then the Visual C++ runtime libraries must be installed prior the installation of these binaries. These runtime libraries are support libraries that are required by any code compiled with the Visual C++ compiler. They can be downloaded for free from the Microsoft download site:
* [http://www.microsoft.com/download/en/details.aspx?id=5582 Visual C++ 2008 runtime libraries]
* [http://www.microsoft.com/download/en/details.aspx?id=8328 Visual C++ 2010 runtime libraries]
Note that if you already installed other software on your system, there is a possibility that these runtime libraries are already present. Search for a files named msvcr90.dll (Visual Studio 2008) or msvcr100.dll (Visual Studio 2010) in the %WINDIR% directory (usually C:\WINDOWS).

===Installation===

The pre-compiled versions for Visual Studio come in the form of a self-installing executable. Simply download the executable, run it and follow the installer instructions. To avoid possible problems with white spaces in the octave paths, it is '''strongly recommended''' to install octave in a directory that do not contain any white spaces.

Octave-Forge packages are not installed by default. To install packages, expand the section "Octave Forge" in the component selection page of the installer and select the packages you wish to install. Note that installed packages are not loaded by default. To use the packages, you still need to load them into octave.

===Printing (installing Ghostscript)===

In order to use the {{Codeline|print}} command ghostscript must be installed.
The installer may be obtained at
[http://sourceforge.net/projects/ghostscript/ sourceforge].

The instructions below assume the GLP version of Ghostscript is installed with
the Destination directory {{Codeline|<nowiki>C:\Program Files (x86)\GPLGS\</nowiki>}}.
The Destination directory may be different for 32 bit and 64 bit windows and can also
change for different versions of Ghostscript.  Therefore, it is important that the user 
make note of the Destination directory used to install Ghostscript and use it in place of
the Destination directory used in these instructions.

In order for Octave to find Ghostscript, the directory containing Ghostscript's command line
program must be in the command shell's path.  The name of Ghostscript's command
line program may vary.  Some examples are {{Codeline|gswin32c.exe}}, {{Codeline|gswin64c.exe}}, 
{{Codeline|gs.exe}}, and {{Codeline|mgs.exe}}.
To directory containing Ghostscript's command line program may either be added to the command
shell's using Windows Control Panel, or by having Octave modify the {{Codeline|path}} variable to
include the directory where Ghostscript's command line programs resides.

For the latter, to following lines may be placed in the {{Codeline|<nowiki>~/.octaverc</nowiki>}}
file (where {{Codeline|~}} indicates the user's home folder).
The variable {{Codeline|<nowiki>gs_path</nowiki>}} should be set to the Destination
directory where Ghostscript was installed.

  cmd_path = getenv ("path");
  gs_path = 'C:\Program Files (x86)\GPLGS\';
  if (isempty (strfind (cmd_path, gs_path)))
    setenv ('path', strcat (cmd_path, pathsep (), gs_path));

In this case, the value of {{Codeline|gs_path}} has been set to the location of Ghostscript's command
line program for the GPL's 8.15 version of Ghostscript.  The location for other versions may differ.
Please determine the location of the installed Ghostscript command line program and make the needed
adjustments to these instructions.

To set the path via the Control Panel,

* Go to '''Control Panel''' --> '''System and Security''' --> '''System'''
* Click '''Advanced System Settings'''
* Click '''Environment Variables'''
* In the '''System Variables''' area, locate the Path variable, highlight it and click '''Edit'''.
* Add the Destination directory where Ghostscript is installed and confirm the change by clickiing '''OK''', '''OK''', '''OK'''.

If the 64 bit version of Ghostscript is installed, Octave will not automatically detect it.  To use the 64 bit version an
option telling Octave about it must be passed to the {{Codeline|print}} command.  For example to produce PDF
output for a figure, using the 64 bit version of Ghostscript, the command below may be used.

  print -Ggswin64c.exe figure.pdf

At this point most of Octave's printing functionality should work.  When output is
produced using the {{Codeline|print}} command the warnings below will be given.

  warning: print.m: epstool binary is not available.
  Some output formats are not available.
  warning: print.m: fig2dev binary is not available.
  Some output formats are not available.
  warning: print.m: pstoedit binary is not available.
  Some output formats are not available.

For the {{Codeline|print}} command to be fully functional, each of these utilities will also need to be installed,
and their locations added to the Path variable via either the Control Panel
or Octave's {{Codeline|<nowiki>~/.octaverc</nowiki>}} file.

===Using the Visual C++ compiler with Octave===

As of version 3.6.1, the Microsoft Visual C++ compiler is not automatically detected. If you need to use it from octave (for instance to compile a MEX, OCT file, and building packages), then you must configure your system by updating the appropriate environment variables: '''%PATH%''', '''%INCLUDE%''' and '''%LIB%'''. One way to achieve this easily is to call the vcvarsall.bat script (from the Visual C++ installation directory) prior executing octave. You can for instance automate this by creating a batch script with the following content (adapt paths to your actual installation):

 call "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat"
 "C:\Octave-3.6.1\bin\octave.exe"

===Alternative===
In addition to the instructions provided in the Octave manual and Octave-Forge repository, a basic toolkit for building Octave in windows using the MSVC compiler has been produced by Michael Goffioul. It consists of a set of scripts that can be used to compile Octave and its dependencies. 

A pre-compiled (with VS2010) version of everything has also been provided, so it is not necessary to recompile everything from scratch. The files can be found at: http://dl.dropbox.com/u/45539519/octave-build2.zip and http://dl.dropbox.com/u/45539519/VC10Libs.zip

Note that this is not a enterprise-level SDK, so don't try to start an enterprise with it.
