Windows doesn't have a shebang mechanism to execute scripts with an arbitrary interpreter. But the <code>makeinfo</code> program in MSYS2 is implemented as a perl script. As a work-around, tell Octave to interpret that file with the <code>perl</code> interpreter. You could do that, e.g., by running the following command to append to the global startup file: | Windows doesn't have a shebang mechanism to execute scripts with an arbitrary interpreter.

A relocation issue with the graphicsmagick library in MSYS2 might cause Octave to crash on certain commands unless it is installed to the default location. To avoid these possible crashes, install Octave (from the MSYS2 shell in {{Path|.build}}) before using it: | A relocation issue with the graphicsmagick library in MSYS2 might cause Octave to crash on certain commands unless it is installed to the default location.

These symlinks are only needed when building the GUI (i.e., Qt is not disabled). This step is no longer necessary with Octave 7 or newer. | These symlinks are only needed when building the GUI (i.e., Qt is not disabled). This step is no longer necessary with Octave 7 or newer. | ||
