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: | |||
<syntaxhighlight lang="bash">make install | <syntaxhighlight lang="bash">echo 'makeinfo_program (sprintf ("%s && cd %s/../usr/bin && perl makeinfo", OCTAVE_HOME ()(1:2), OCTAVE_HOME ()));' >> "${MINGW_PREFIX}/share/octave/site/m/startup/octaverc"</syntaxhighlight> | ||
ln -sf /mingw64/libexec/octave/7.0.0/exec/x86_64-w64-mingw32/octave-gui.exe /mingw64/bin/octave-gui.exe | This has to be done only once. | ||
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: | |||
<syntaxhighlight lang="bash">make install</syntaxhighlight> | |||
Windows' library lookup mechanism requires that the following executables are installed in the same folder like the libraries they depend on. That can be achieved by creating symlinks to these executables in the "correct" location: | |||
<syntaxhighlight lang="bash">ln -sf /mingw64/libexec/octave/7.0.0/exec/x86_64-w64-mingw32/octave-gui.exe /mingw64/bin/octave-gui.exe | |||
ln -sf /mingw64/libexec/octave/7.0.0/exec/x86_64-w64-mingw32/octave-svgconvert.exe /mingw64/bin/octave-svgconvert.exe</syntaxhighlight> | ln -sf /mingw64/libexec/octave/7.0.0/exec/x86_64-w64-mingw32/octave-svgconvert.exe /mingw64/bin/octave-svgconvert.exe</syntaxhighlight> | ||
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. | |||
At this point, Octave's GUI can be started with the command <code>octave --gui</code> at the MSYS2/MINGW64 shell. | |||
If you'd like to start Octave from a CMD shell (or with a batch script), the following commands could be used (assuming MSYS2 was installed in its default location): | |||
<syntaxhighlight lang="batch">set PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH% | <syntaxhighlight lang="batch">set PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH% | ||
set MSYSTEM=MINGW64 | set MSYSTEM=MINGW64 | ||
