Octave can be built on cygwin too ! | |||
==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! | |||
