The only ''tricky'' part is to install the dependencies. Once that is solved, installing from source should be as easy as {{Codeline|./configure && make && make install}}. See the manual for the [http://www.gnu.org/software/octave/doc/interpreter/Running-Configure-and-Make.html configure options].

=== HDF5 issue ===
=== Install dependencies ===
With new Debian versions you may get the following when building from source:


{{warning|HDF5 library not found.  Octave will not be able to save or load HDF5 data files.}}
Note that different Debian and Ubuntu versions may have slightly different package names but their differences should be pretty small, mostly limited to version numbers.


The problem is that there are multiple versions of the hdf5 package.  Octave was written with the serial version in mind but it is likely to work with the others (OpenMPI and Mpich). Due to the naming scheme done in Debian, it is required to specify the location of the libraries.  See bug {{bug|38928}} for details but basically, use the following when running configure:
==== The easy way (but possibly incomplete) ====
 
./configure CPPFLAGS=-I/usr/include/hdf5/serial LDFLAGS=-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)/hdf5/serial
 
=== Dependencies ===
{{Note|different Debian and Ubuntu versions may have slightly different package names but their differences should be pretty small, mostly limited to version numbers.}}


==== The easy way (but possibly incomplete) ====
The easy way to install ''most'' of the necessary dependencies is to {{Codeline|sudo apt-get build-dep octave}}. This will install all packages necessary to build and prepare a Debian package for the octave version available on your system repositories. However:

The [http://wiki.octave.org/MXE MXE-octave] package provides a way to compile Octave for different platforms. Dependencies and certain flags are handled automatically.

The best way is to select and install all the dependencies as listed in the {{Path|INSTALL.OCTAVE}} file. The following are their package names in Debian repositories (they will have their own dependencies which your package maintainer will solve automatically).


{{Warning|Debian repositories has several libraries for dealing with HDF data files. The recommended is {{Codeline|libhdf5-serial-dev}}. However, the {{Forge|msh|msh package}} requires [http://www.geuz.org/gmsh/ gmsh] which is incompatible with it.}}

The following are their package names in Debian repositories (they will have their own dependencies which your package maintainer will solve automatically). If you are building development versions, you'll require some more packages as listed on {{Path|etc/HACKING}} and {{Path|INSTALL}}. Many of them will already be installed on your system.

===== Development tools =====
=== Configuration ===


<pre>autoconf automake bison flex gperf gzip icoutils librsvg2-bin libtool perl rsync tar</pre>
==== HDF5 issue ====


===== Extra dependencies for the development version =====
With current Debian versions you may get the following when building from source:


At the moment, thereare no extra dependencies to build the development version.
HDF5 library not found.  Octave will not be able to save or load HDF5 data files.

The problem is that there are multiple versions of the hdf5 package.  Octave was written with the serial version in mind but it is likely to work with the others (OpenMPI and Mpich). Due to the naming scheme done in Debian, it is required to specify the location of the libraries.  See bug {{bug|38928}} for details but basically, use the following when running configure:
