- This article is about how to make the Microsoft Windows installer; if you'd like just to use the installer, see Octave for Microsoft Windows.
GNU Octave is primarily developed on GNU/Linux and other POSIX compliant systems. There have been many efforts in the past to build ports of GNU Octave for Microsoft Windows. This page contains instructions about creating a MS Windows installer using mxe-octave (a fork of MXE). This means, the MS Windows installer is cross-compiled using a GNU/Linux system.
Creating the MS Windows Installer
- Install the MXE build requirements.
hg clone https://hg.octave.org/mxe-octave
make all nsis-installer
The current Microsoft Windows installers are build in three "flavors": for common 64- and 32-bit systems ("w64" and "w32") and for 64-bit systems exceeding 32 GB of main memory to store large data structures ("w64-64").
./configure \ --enable-devel-tools \ --enable-binary-packages \ --with-ccache \ --enable-octave=<octave version>
./configure \ --enable-devel-tools \ --enable-binary-packages \ --with-ccache \ --enable-octave=<octave version> \ --enable-fortran-int64
./configure \ --enable-devel-tools \ --enable-binary-packages \ --with-ccache \ --enable-octave=<octave version> \ --disable-windows-64
The individual options have the following meaning (see also
--enable-devel-tools: Include gdb and an MSYS shell in the binary.
- If you seriously want to work with gdb, you need
--disable-strip-dist-filesas configure option to keep debug symbols in the installed binaries for debugging on MS Windows. Beware as the total Octave distribution will be > 2 GB, the max. size for an NSIS installer. Your only options are to make 7z-dist, zip-dist or tar-dist installers.
- If you seriously want to work with gdb, you need
--enable-binary-packages: Cross-compile binary modules in Octave Forge packages. This saves time when installing them once the installation runs on Microsoft Windows. Furthermore, some packages require patches to cross-compile successfully (or with current Octave versions). Those additional patches would be missing when compiling the original packages from Octave Forge on Windows later on. Some Octave Forge packages require a working Octave during compilation. Therefore, the correct version(!) of Octave must be installed on the host system.
--with-ccache: The usage of ccache may speed up repetitive compilation drastically.
--enable-octave=<octave version>: Build a specific version of GNU Octave, which can be one of:
releaseuse src/release-octave.mk, download and build the latest GNU Octave release.
defaultuses src/stable-octave.mk or src/default-octave.mk, respectively. This builds from a self-created distribution tarball from the "stable" or "default" development branch of GNU Octave. See below for details.
--disable-windows-64: Build for 32-bit MS Windows.
--enable-fortran-int64: Use 64-bit integers in Fortran code and especially in numerical library code. This option only affects the size of integers used in Fortran code like the BLAS and LAPACK libraries. On 64-bit systems, Octave always uses 64-bit integers for indexing and basic array operations. See Enable large arrays for details.
--disable-system-opengl: Include software OpenGL libraries. This might help when working with buggy graphics card drivers, but might be slower than hardware accelerated rendering.
--with-pkg-dir=../mxe-octave-pkg: If you are working with several build trees, you can share a common package directory.
make all 7z-dist,
make all tar-distor
make all zip-distinstead of
make all nsis-installerif you want to build just an archive of the files to install on MS Windows instead of an installer wizard.
- By default, packages will be built one at a time, but you may use
make JOBS=4(choose a number other than 4 that is appropriate for your system) to build each package in parallel. You may also combine this with the
-joption for Make to build more than one package at a time, but be careful as using
make -j4 JOBS=4can result in as many as 16 jobs running at once.
- Include gdb in the installer by running
make gdbbefore making the
Build installers for Octave development versions
- Build the "stable" or "default" Octave development branch on Linux (in separate source and build trees) including your favorite modifications and patches. Octave must be configured with Java support. How to do this depends on your Linux distribution, see Octave for GNU/Linux.
- Verify that Octave runs fine in Linux (for example using
make checkand by trying to run your build
- Create a distribution archive called "octave-<version>.tar.lz" in the top build directory with
make dist-lzip DIST_IGNORE_HG_STATE=1.
- Move or copy "octave-<version>.tar.lz" to the <mxe-octave build>/pkg folder (or create a symbolic link to it).
- Follow the general steps and ensure the configuration with either of
- Move the final installer in <mxe-octave build>/dist to some Microsoft Windows machine (USB thumb drive, LAN copy, whatever) and install it "as usual". If you created an archive, using
make all 7z-distfor example, you'll have to manually create the desktop and start menu shortcuts (for GNU Octave and the MSYS-shell).
For next builds, mxe-octave is already configured and all dependencies have been built so the only thing to do is to create a new "octave-<version>.tar.lz" and repeating the steps above. This should be much faster than the first run. If the new "octave-<version>.tar.lz" is not build and ignored, try the following:
If you've renamed "octave-<version>.tar.lz", be sure it matches with the package name in src/default-octave.mk.
- If you have several mxe-octave build dirs (for e.g., stable and several development versions) it is handy to have a separate pkg subdirectory where all mxe-octave build directories link to via an symbolic link, for example. That saves a lot of downloading bandwidth.
- As of late December 2015, mxe-octave allows out-of-tree builds. This makes it easier to build separate Octave versions with the same mxe-octave tree.
- To keep mxe-octave up-to-date, from time to time do:
hg -v pull hg -v update
- However, do not keep mxe-octave build dirs for too long. I'd suggest to wipe a build dir after at most two or three months and start over with a fresh clone, see [#General steps|general steps].
- In the mean time, regularly clean up <mxe-octave build>/log to save disk space. After a first successful build there is no more use for the log subdirectories for each package. One can safely wipe them all.
- It can happen that you meet problems with Java. To build Octave with Java support built-in, mxe-octave needs:
- A Java JDK (Java Development Kit) on the host system. In other words, the javac (Java compiler) and jar (Java archiver) executables should be in the PATH-system-variable.
- Java include files for MS Windows ("w32", even for "w64" builds). They should reside in <mxe-octave build dir>/usr/x86_64-w64-mingw32/include/java/win32. If they are not present, mxe-octave downloads them automatically, but this can occasionally go wrong. On a multi-boot system a solution (note: dirty hack warning!) is symlinking to the MS Windows include files on the MS Windows partition from the mxe-octave location.
- The error message displayed by
makeis simply the last lines of the log file. This may truncate the actual error message. Find the full error messages in the <mxe-octave build>/log directory.
- Sometimes running
makea second time without changing anything will fix the problem. In particular,
autotoolsrebuilds some files in the first call
make, which may cause the second call of
- If it is building Octave that failed, the source will be left in <mxe-octave build>/tmp-default-octave and it is possible to run "configure && make" in that directory.
- The configuration will be for the target system, not your own. In particular, if you have not installed all of the packages that mxe-octave installs, then your configuration will be different. However, some configuration variables will differ even if you have the same packages, and some compiler features may be available on the host system that are not available in cross-compile mode.
- A possible causes for build failure is having files in your local source or build directory that are not listed in the module.mk files; these are not copied into the dist archive.
- Sometimes mxe-octave builds fail at "libmng". This may be due to a race condition related to disk I/O when using a fast SSD harddisk. A way to get past this is by specifying "make nsis-installer JOBS=1", if required repeatedly (sometimes 5 or 6 times), interrupting the build in the next step/dependency once "libmng" has been built fine, and restarting with "make nsis-installer JOBS=<higher number>". As of December 2015 it is only libmng that has this issue.
Testing using virtual machines
Microsoft provides several virtual machine (e.g. VirtualBox) disk images of MS Windows for about one month of testing
- https://developer.microsoft.com/en-us/microsoft-edge/tools/vms (primarily meant for testing the MS-Edge browser)
The license (given on that page) for these images does not limit the use of these images. So it is perfectly possible to also test GNU Octave.
The key idea is to create a shared folder inside the virtual machine to the mxe-octave build directory. It is advised to make it read-only. Either install (or unpack) Octave into MS Windows 10, or create a shortcut to octave.vbs in the <mxe-octave build dir>/dist/octave subdirectory on the Linux side.
- No dedicated MS Windows machine or rebooting from Linux is needed;
latestMS Windows 10 version is always available;
- Building the installer archives (zip, 7z, ...) isn't needed. One can interrupt the build process after the local installation of Octave has been made in the dist/octave subdirectory of mxe-octave, i.e., when the message "generating installer" (or "zip...") is shown. This saves about 10-15 minutes. Of course one can also use the common distribution formats for the virtual MS Windows machine.
- When adapting mxe-octave/binary-dist-rules.mk to have a consistent name for the <mxe-octave build dir>/dist/octave subdirectory (i.e., without time/date/bitwidth suffixes) so that in MS Windows the shortcut doesn't need adaptation after each cross-build action. Maybe it is better if mxe-octave/binary-dist-rules.mk has a rule to create a symlink <mxe-octave build dir>/dist/octave pointing to the latest cross-build.
- The image expires after 90 days. But if you make a VirtualBox snapshot it will last longer, and you don't need to uninstall Octave each time before installing a new build.
- The requirements for each system are listed in the repository https://hg.octave.org/mxe-octave/file/tip/index.html. Start with the second step to read the index.html file on your local machine.
hg clone https://hg.octave.org/mxe-octave <name of mxe-octave build dir>to choose another directory.
