MXE-Octave is really intended to be used to cross compile Octave along with all dependencies for Windows systems.  It may also be used to do native builds on Windows if you have a minimal set of MinGW tools installed, or to do native builds on Linux systems.  However, it was really only intended as a way to build Octave on systems that lack sufficiently recent versions of tools and libraries to build Octave.

MXE-Octave is based on the MXE project and is useful for the following scenarios:

  1. Cross-compilation for MS Windows (see also Windows_Installer) and other platforms.
  2. Building Octave on outdated Linux systems (e.g. only an old GCC version is available).
  3. Building Octave without root permission.

MXE-Octave is not the best choice for building Octave, if your system already provides recent versions of GCC and other required build dependencies.

Examples of compiling Octave for different platforms

  • Compiling for your Linux system
  1. Download MXE-Octave as a compressed file.
  2. Unpack it in ~ or somewhere suitable.
  3. Check you have all the requirements, gfortran and libgl2ps-dev.
  4. cd into the directory (called ~/mxe-octave-123456789 or similiar).
  5. Type: ./bootstrap
  6. Type: ./configure --enable-64 --enable-native-build --enable-pic-flag host_alias=gnu-linux --enable-openblas --enable-jit
  7. Type: make
  8. Type: make openblas
  9. cd usr/lib
  10. mv libblas.so libblas.so.reference
  11. ln -s libopenblas.so libblas.so
  12. Octave will exist in ~/mxe-octave-123456789/usr/bin
  13. Add to your .bashrc file: alias octave=~/mxe-octave-123456789/usr/bin/octave

It's that easy...

  • Compiling for your Ubuntu Desktop x64 Linux (tested for 14.xx)
  1. In Ubuntu Desktop Linux 14.10 the above recipe fails during building BLAS library ...
  2. I have found a working solution how to build Octave 3.8.2 with ---enable-64 in Ubuntu Desktop Linux - see:
  3. BLOG: http://calaba.tumblr.com/post/107087607479/octave-64
  4. GitHub: https://github.com/calaba/octave-3.8.2-enable-64-ubuntu-14.04


Note for gnuplot

The gnuplot built by mxe-octave does not support cairo based terminals and lua/tikz terminals. If you want uses those feature, prepare gnuplot with those features and points its location setting to "gnuplot_binary" like

 >> gnuplot_binary /usr/bin/gnuplot
