(Be aware that this might take some time.) It is also possible to build Octave on Windows machines using virtual machines or Microsoft's Windows Subsystem for Linux. The latter is the preferred way to build Octave. | ||
Building Octave natively on Windows is experimental! The only supported way of creating Windows binaries of Octave is cross-building with MXE Octave ([[Windows Installer]]). | |||
