| Octave can be built on cygwin too !
| | #REDIRECT [[Octave for Microsoft Windows#GNU Octave on cygwin]] |
| | |
| ==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!
