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. | ||

They should reside in {{Path|<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. | ||

In particular, if you have not installed all of the packages that mxe-octave installs, then your configuration will be different.

* | * 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 90 days of testing https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/. While 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 to just MS-Edge. 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 {{Path|octave.vbs}} in the {{Path|<mxe-octave build dir>/dist/octave}} subdirectory on the Linux side. | |||
Some advantages: | |||
* | * No dedicated MS Windows machine or rebooting from Linux is needed; | ||
* | * The <strike>latest</strike> MS 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. | |||
Hints: | Hints: | ||
* | * When adapting {{Path|mxe-octave/binary-dist-rules.mk}} to have a consistent name for the {{Path|<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 {{Path|mxe-octave/binary-dist-rules.mk}} has a rule to create a symlink {{Path|<mxe-octave build dir>/dist/octave}} pointing to the latest cross-build. | ||
