* ''This article addresses the [[:Category:Installation|installation]] and [[Building]] of GNU Octave on Debian, and Debian-based distributions such as Ubuntu.''
+
For Debian, and Debian based distributions such as Ubuntu, specific solutions.
  
Binary packages for GNU Octave and many [[Octave Forge]] packages are provided by all versions of Debian and Ubuntu. These are the most well-tested binaries available and should work best for most users. To install them, run:
+
== Pre-compiled binaries ==

 +
Binary packages for Octave and many Octave-Forge packages are provided by all versions of Debian and Ubuntu. These are the most well-tested binaries available and should work best for most users.
  
 
  sudo apt-get install octave
 
  sudo apt-get install octave
  
In Debian and Ubuntu the "complete" GNU Octave software is split over multiple packages. To obtain the complete features of Octave, install additionally
+
Aside the {{codeline|octave}} package that installs GNU Octave, other pieces of it are split over multiple packages. These are {{codeline|octave-doc}}, {{codeline|octave-info}}, and {{codeline|octave-htmldoc}} for the documentation; {{codeline|liboctave-dev}} for the octave development header files and mkoctfile (required to install Octave Forge packages); and {{codeline|octave-dbg}} for the debugging symbols.
  
* {{codeline|octave-doc}}, {{codeline|octave-info}}, and {{codeline|octave-htmldoc}} for the documentation;
+
For Debian stable users, there may also be newer packages available in backports, so don't forget to check there.
* {{codeline|liboctave-dev}} for the octave development header files and mkoctfile (required to install Octave Forge packages); and
 
* {{codeline|octave-dbg}} for the debugging symbols.
 
  
Many Octave packages are also distributed by Debian and Ubuntu.  These are tested to work the best with the respective Octave version.  Install them via:
+
=== Octave packages ===
 +
 
 +
Many Octave packages are also distributed by your Linux distribution.  These are tested to work the best with your Octave version.  For example:
  
 
  sudo apt-get install octave-control octave-image octave-io octave-optim octave-signal octave-statistics
 
  sudo apt-get install octave-control octave-image octave-io octave-optim octave-signal octave-statistics
  
Up to 2018, the [https://launchpad.net/~octave GNU Octave Team] on Launchpad actively maintained a PPA providing more up to date packages of Octave. These are backported from Debian unstable and are still useful for older Ubuntu installations. To set up your system to install these packages, run:
+
=== Octave's Personal Package Archive (PPA) for Ubuntu ===
 +
 
 +
For some Ubuntu releases the octave packages are too old (Ubuntu 12.04 only has Octave version 3.2).  The [https://launchpad.net/~octave GNU Octave Team] on Launchpad maintains a PPA providing more up to date packages of Octave for all versions of Ubuntu. These are backported from Debian unstable (the Ubuntu Octave Team needs help testing and preparing the packages so if you can help with this, contact [[User:Mtmiller|Mike Miller]]). To set up your system to install these packages:
  
 
  sudo apt-add-repository ppa:octave/stable
 
  sudo apt-add-repository ppa:octave/stable
Line 21: Line 25:
 
  sudo apt-get install octave
 
  sudo apt-get install octave
  
== Building Octave ==

== Compiling from source ==
  
: ''For general build instructions, see [[Building]].''
+
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 [http://www.gnu.org/software/octave/doc/interpreter/Running-Configure-and-Make.html configure options] and [[Octave_for_Debian_systems#Configuration|below]] for some common examples.
 
 
The ''only'' tricky part is to install the Octave build dependencies. Once that is solved, one can easily follow the [[Building|general build instructions]].  See [[#Configuration|below]] for some Debian and Ubuntu specific configuration options.

==== The even easier way (but experimental) ====
  
The right way is to install all the dependencies listed on the [[Building#Dependencies|Building]] wiki page. One can either search for the respective packages manually on

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

or, for the sake of convenience, use some "one-liner" to install them:
+
The right 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 manager 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. Install the dependencies by typing

As mentioned above, Octave can be compiled with the default settings using {{Codeline|./configure && make && make install}}. You can also tweak the setup using configure options. Some examples are given below for a Linux system.

To get [https://www.gnu.org/software/octave/doc/interpreter/Compiling-Octave-with-64_002dbit-Indexing.html 64-bit] requires all linked libraries to support 64-bit variables. You can omit most of these except BLAS which gives a fatal error. This is remedied by compiling [http://www.openblas.net/ OpenBLAS] with edits to its Makefile.rule so that BINARY=64 INTERFACE64=1.

==== Java JIT ====
  
 +
To get the just-in-time compiler, you should specify the location of the java compiler since the autodetection script often fails.
  
{{Warning|<ul><li>The Debian repositoriy 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.</li>
+
<code>./configure JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64" --enable-jit</code>
<li>The GraphicsMagick++ library (libgraphicsmagick++1-dev) on the Debian repositories was compiled with quantum 8 which limits reading images to 8 bit. The solution is to recompile [[GraphicsMagick]] with quantum 16 or 32 before building Octave.</li>
 
<li>For debian9 using openjdk-9-jdk (even providing  {{Codeline|JAVA_HOME}}) could *not* be used for the java interface! Use openjdk-8-jdk instead.</li>
 
<li>When configure decides to use QT5 instead of QT4, make might fail because lrelease is missing (see [https://savannah.gnu.org/bugs/?50580 bug 50580]).  It can be fixed by installing {{Codeline|qttools5-dev-tools}}</li>
 
</ul>}}
 
 
 
=== Configuration ===
 
 
 
Some Debian and Ubuntu specific configure tweaks are listed below:
 
 
 
==== Java ====
 
 
 
Autodetection for Java should work well on Debian-based systems. A specific Java version can be specified by passing {{codeline|JAVA_HOME}} to configure, for example
 
 
 
./configure JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
 
  
 
==== HDF5 ====

On older versions of Debian and Ubuntu, you may get the following warning when building an older version of Octave from source:

  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 may be required to specify the location of the libraries.  See bug {{bug|38928}} for details (starting with comment #19) but basically, use the following when running configure:

./configure --with-hdf5-includedir=/usr/include/hdf5/serial --with-hdf5-libdir=/usr/lib/x86_64-linux-gnu/hdf5/serial
 
 
 
On older versions of Debian and Ubuntu, where only one flavor of the HDF5 library could be installed at a time, you may need to build Octave against one of the MPI-enabled flavors. On these older systems, configuring Octave like this may work:
 
  
  ./configure CPPFLAGS="-I/usr/include/mpi -DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX"
+
  ./configure CPPFLAGS=-I/usr/include/hdf5/serial LDFLAGS=-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)/hdf5/serial
  
==== Sundials ====

Another issue you may have on Debian systems, even when using the correct hdf5 libraries, is that they are installed in a non-standard location which is not found by configure. This will result in the following warning after running configure:
  
On recent Debian and Ubuntu releases whose Sundials version (in {{codeline|libsundials-dev}}) is 3.1, a configure flag needs to be passed for {{codeline|ode15i}} and {{codeline|ode15s}} to be compiled with support for sparse Jacobians (bug {{bug|55937}}), as follows:
+
  WARNING: HDF5 library not found. Octave will not be able to save or load HDF5 data files.
  
./configure CPPFLAGS="-I/usr/include/suitesparse"
+
To avoid this you can manually specify the hdf5 locations in the following way:
  
== See also ==
+
  ./configure --with-hdf5-includedir=/usr/include/hdf5/serial --with-hdf5-libdir=/usr/lib/x86_64-linux-gnu/hdf5/serial
