-==Pre-requisites==
-Setup your system the same way as described on the page [[Octave for Debian systems]]. The next step, required to generate the documentation, is to tweak a bit the texlive configuration file: (remember cygwin has no sudo command)
-    vi /usr/share/texmf-dist/web2c
-Change
-    TEXMFLOCAL = $TEXMFROOT/texmf-site
-into
-    TEXMFLOCAL = $TEXMFROOT/texmf-site:$TEXMFROOT/texmf
-Then run
-    mktexlsr
-==Configure==
-Proceed the same way as on a Unix platform. In this case, the procedure requires a kind of bootstrapping, so it is better to put Octave outside the main directory tree; like f.i.
-    ./bootstrap
-    mkdir compile; cd compile
-    ../configure --prefix=${HOME}/usr
-This configuration supposes ${HOME}/usr/bin exists and is in your $PATH.
-==Build==
-The procedure is a bit more tricky. Start the build as usual:
-    make -j 2
-It will fail after a looong time, while trying to launch ./run-octave. This is a well-known problem, partly caused by issues with the fork() call under Windows platforms. At this time, change run-octave to something simpler:
-    #! /bin/sh
-    octave_executable="${PREFIX}/usr/bin/octave"
-    "$octave_executable" "$@"
-Where ${PREFIX} matches the form previously used during the configure stage. In fact, we will use the new Octave, which is not yet operationnal. But never mind. Restart the process as follows:
-    make install
-This way:
-# The Octave libs and binaries have been generated, they will be copied into their final destination directory.
-# the doc has still to be built. With the modified "run-octave", the executable which will be called is the version just installed during the previous step. Now the doc generation will succeed, and so will its installation.
-Enjoy!
