==== Preparation ==== | |||

# <code>hg clone https://hg.octave.org/mxe-octave | # Decide for an installation directory (e.g. {{path|~/mxe-octave}}). | ||

==== Configuration ==== | |||
For a comprehensive list of configuration options with a short explanation, type <code>./configure --help</code>. See also the [[#Known issues|known issues]] below. | |||
<syntaxhighlight lang="text"> | |||
./configure \ | |||
--prefix=$HOME/mxe-octave \ | |||
--enable-native-build \ | |||
--enable-octave=release \ | |||
--enable-64 \ | |||
--enable-binary-packages \ | |||
--enable-devel-tools \ | |||
--enable-fortran-int64 \ | |||
--enable-lib64-directory \ | |||
--enable-openblas \ | |||
--enable-pic-flag \ | |||

</syntaxhighlight> | |||
==== Build ==== | |||
<code>make -j3 JOBS=2 all openblas</code> Adapt the values of the variables <code>-j</code> (parallel package builds) and <code>JOBS</code> (parallel build jobs) to your needs. | |||
==== Replace reference BLAS by OpenBLAS ==== | |||
In general using the [https://www.openblas.net/ OpenBLAS] library results in faster matrix-vector operations compared to the reference BLAS library. | |||
# <code>cd ~/mxe-octave/usr/lib</code> | # <code>cd ~/mxe-octave/usr/lib</code> | ||
# <code>mv libblas.so libblas.so.reference</code> | # <code>mv libblas.so libblas.so.reference</code> | ||
# <code>ln -s libopenblas.so libblas.so</code> | # <code>ln -s libopenblas.so libblas.so</code> | ||
==== Run ==== | |||
# MXE-Octave will exist in {{path|~/mxe-octave/usr/bin}} | # MXE-Octave will exist in {{path|~/mxe-octave/usr/bin}} | ||
# Add to your {{path|.bashrc}} file: <code>alias octave=~/mxe-octave | # Add the command <code>octave</code> as alias to your {{path|.bashrc}} file: <code>alias octave=~/mxe-octave/usr/bin/octave</code> | ||
# Start MXE-Octave by typing <code>octave</code>. | |||
=== | === Known issues === | ||
The gnuplot built by | ==== gnuplot ==== | ||
If you want uses those | |||
The gnuplot built by MXE-Octave does not support cairo based terminals and lua/tikz terminals. | |||
If you want uses those features, prepare gnuplot with those features and type in the Octave command prompt | |||
>> gnuplot_binary /usr/bin/gnuplot | >> gnuplot_binary /usr/bin/gnuplot | ||
==== Build errors on older systems ==== | |||
On some older systems, it might be useful to consider adding the configuration options | |||
* <code>--disable-docs</code> | |||
* <code>--disable-java</code> | |||
in case of building errors. | |||
