- This article is about how to make the 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 conformal systems. There have been many efforts in the past to build ports of GNU Octave for Windows. Take a look at the various ports of Octave available for Windows here.
Recently some work has been done in maintaining a unified build system mxe-octave (a fork of MXE) which anyone can use to produce cross as well as native builds of GNU Octave for Windows and Mac OS X platforms. This page contains instructions about creating a Windows installer using mxe-octave.
Steps to create Windows Installer
- Install all requirements of MXE Octave.
hg clone http://hg.octave.org/mxe-octave/
make zip-distinstead of
nsis-installerif you want to build just an archive of the files to install on 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.
./configure --disable-strip-dist-filesif you want to keep debug symbols in the installed binaries for debugging on Windows. Beware as the total Octave distribution will be > 2 GB, the max. size for an NSIS installer.Your only options are to make zip-dist or tar-dist installers.
- Include gdb in the installer by running
make gdbbefore making the
Creating Octave development versions for Windows with mxe-octave
To roll your own octave for windows version with your favorite mods and patches, you can do as follows:
- Make the cross-build environment for Octave (=mxe-octave; see above)
- Build an Octave dist archive in Linux
- Move that into mxe-octave and cross-build Octave + windows installer.
For ensuing builds after a first build, you'll only need to follow steps 2 + a little amended step 3 (see below)
Step 1: Prepare mxe-octave
Clone the mxe-octave reop to some directory of your choice:
http://hg/octave.org/mxe-octave <name of mxe-octave build dir>
where <name of mxe-octave build dir> is some other name than just the default "mxe-octave". Once downloaded, go into the <name of mxe-octave build dir> subdir and do:
.autoconf ./configure <options you want> make nsis-installer JOBS=<some number>
Your author usually has "--enable-devel-tools --enable-windows-64 --enable-octave=default --enable-binary-packages" as configure options and use JOBS=7 on my core i5 system.
- the first configure option also includes gdb and an MSYS shell in the binary
- the second avoids the ~700 MB max. array size limit for 32-bit executables but Octave will only run on 64-bit Windows (most Windows systems are 64 bit anyway these days). Note: this option does NOT imply 64-bit indexing
- the third option is just for a placeholder; it'll invoke src/default-octave.mk (one of the three octave .mk files in mxe: src/stable-octave.mk and src/octave.mk, corresponding to the "--enable-octave=" configure option), I found that octave.mk lags a bit behind
- the fourth option cross-compiles the binary modules in Octave-Forge packages, which wil save time when installing them once in Windows.
If you seriously want to work with gdb, also have --disable-strip-dist-files as configure option. However, in that case chances are that you cannot build an .exe installer anymore as it becomes too big for NSIS (that has a 2 GB installer file size limit) so instead of "make nsis-installer" you'll need to invoke
make zip-dist <options>
....and this results in all Octave dependencies being built in mxe-octave, plus (stable) Octave, plus an initial version of a binary Octave-Windows installer in the <mxe-octave build>/dist/ subdirectoy.
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. IOW, the javac (Java compiler) and jar (Java archiver) executables should be in the PATH.
- Java include files for windows (win32, even for w64 builds). They should reside in "<mxe-octave build dir>/usr/x86_64-w64-mingw32/include/java/win32". If not present, mxe-octave downloads them but this can occasionally go wrong. On a multi-boot system a solution (note: dirty hack warning!) is symlinking to the Windows include files on the Windows partition from the mxe-octave location.
Step 2: To build your first Octave-for Windows development version:
- build Octave on Linux (in separate source and build trees) including your favorite mods and patches.
- once Octave runs fine in Linux (using make check and trying your mods using ./run-octave & from the build dir, all of this still on the Linux side), do:
make all dist
- This will produce a dist archive called "octave-<version>.tar.gz" in the top directory. Move or copy this dist archive to the <mxe-octave build>/pkg folder (or symlink to it from there)
Note that this step requires the Octave be configured with Java (i.e., you need javac and jar on your system).
Step 3: Building the Octave installer
- be sure to adapt <mxe-octave build>/src/default-octave.mk to read "## No Checksum" at the $(PKG)_CHECKSUM line and check octave version and archive type (tar.gz rather than tar.bz2). The checksum is only needed when you download a dist archive from the Internet, not so much when you copy it within your own home network, let alone your own computer.
- check if in the top of the main Makefile "default-octave" is mentioned for OCTAVE_TARGET rather than "stable-octave" of just "octave" (that name refers to the .mk filename in the src folder).
- ... and then run (in the <mxe-octave build> folder)
make nsis-installer <options> -or- make zip-dist <options>
Step 3A (second and later builds)
For next builds, mxe-octave is already configured and all dependencies have been built so the only thing to do is having a new Octave version + installer built:
- move/copy the dist archive from step 2 into mxe-octave's pkg subdir
- in <mxe-octave build> root dir do:
(to be sure mxe-octave picks up the new Octave archive). If you've renamed the dist archive, be sure it matches with the package name in src/default-octave.mk. Then do:
make nsis-installer -or- make zip-dist
Step 4: Install on Windows
- move the installer in <mxe-octave build>/dist/ to the Windows side (USB thumb drive, LAN copy, whatever).
- install it there.
If you've made a zip-dist you'll have to manually create the desktop and Start Menu shortcuts (for octave and the MSYS-shell).
- If you have several mxe-octave build dirs (for e.g., stable and several development versions) it is handy to have a separate pkg subdir symlinked to from all mxe-octave build dirs. That will save a lot of downloading bandwidth.
- As of late Dec 2015, mxe-octave allows out-of-tree builds, which makes it a lot easier to build separate Octave versions with the same mxe-octave tree. (See http://hg.octave.org/mxe-octave/rev/0962acdde3be)
- 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 a la Step 1.
- Sometimes, when using the "--enable-binary-packages" flag, it happens that Octave-Forge packages with binary modules don't work well on the Windows side. Usually the cause is that the Octave dev version has changed too much since the last cross-build of the OF packages. Solution: just do in <mxe-octave>/:
touch src/of*.mk make <OPTIONS>
mxe-octave will rebuild all OF packages then incl. the offending binary modules.
- In the mean time, regularly clean up <mxe-octave build>/log to save disk space. After a first successful build there's no more use for the log subdirs for each package, so you can wipe them all.
If things go wrong
It is possible that, for example, the build of Octave in step 2 works but that if fails in step 3. Here are some troubleshooting tips.
- The error message displayed by make is simply the last 10 lines of the log file. This may truncate the actual error message.
- Sometimes running "make" a second time without changing anything will fix the problem. In particular, autotools rebuilds some files in the first make which may cause the second make to succeed.
- 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.
- (philip, confirmed by oheim) On my core i5 desktop system with a fast SSD, mxe-octave builds usually fails at libmng, suspectedly because of a race condition related to disk I/O. 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 Dec. 2015 it is only libmng that has this issue.
