The following external packages are required:
Basic Linear Algebra Subroutine library. Accelerated BLAS libraries such as OpenBLAS (https://www.openblas.net/) or ATLAS (http://math-atlas.sourceforge.net) are recommended for best performance. The reference implementation (http://www.netlib.org/blas) is slow, unmaintained, and suffers from certain bugs in corner case inputs.
Linear Algebra Package (http://www.netlib.org/lapack).
The Perl Compatible Regular Expression library (https://www.pcre.org).
The following external package is optional but strongly recommended:
Command-line editing library (https://www.gnu.org/s/readline).
If you wish to build Octave without GNU readline installed, you must use the --disable-readline option when running the configure script.
The following external software packages are optional but recommended:
Library for the solution of large-scale eigenvalue problems
(https://forge.scilab.org/index.php/p/arpack-ng). ARPACK is
required to provide the functions
Library for transferring data with URL syntax
(https://curl.haxx.se). cURL is required to provide the
urlwrite functions and the
Library for computing discrete Fourier transforms
(http://www.fftw.org). FFTW3 is used to provide better
performance for functions that compute discrete Fourier transforms
Portable GUI toolkit (http://www.fltk.org). FLTK can be used to provide windows for Octave’s OpenGL-based graphics functions.
Library for configuring and customizing font access (https://www.freedesktop.org/wiki/Software/fontconfig). Fontconfig is used to manage fonts for Octave’s OpenGL-based graphics functions.
Portable font engine (https://www.freetype.org). FreeType is used to perform font rendering for Octave’s OpenGL-based graphics functions.
GNU Linear Programming Kit (https://www.gnu.org/software/glpk).
GPLK is required for the function
OpenGL to PostScript printing library (https://www.geuz.org/gl2ps/). gl2ps is required for printing when using OpenGL-based graphics toolkits (currently either FLTK or Qt).
Interactive graphics program (http://www.gnuplot.info). gnuplot can be used as a graphics renderer for Octave; prior to Octave 4.0, gnuplot was the default graphics renderer.
Image processing library (http://www.graphicsmagick.org).
GraphicsMagick++ is used to provide the
Library for manipulating portable data files
(https://www.hdfgroup.org/HDF5). HDF5 is required for Octave’s
save commands to read and write HDF data files.
Java programming language compiler and libraries. The OpenJDK free software implementation is recommended (http://openjdk.java.net/), although other JDK implementations may work. Java is required to be able to call Java functions from within Octave.
Compiler framework, (https://www.llvm.org). LLVM is required for Octave’s experimental just-in-time (JIT) compilation for speeding up the interpreter.
API for portable 2-D and 3-D graphics (https://www.opengl.org). An
OpenGL implementation can be used to provide a renderer for Octave’s
graphics functions. Octave’s OpenGL-based graphics functions usually
outperform the gnuplot-based graphics functions because plot data can be
rendered directly instead of sending data and commands to gnuplot for
interpretation and rendering. Since Octave 4.0, the default graphics
"qt") has been OpenGL-based.
PortAudio (http://www.portaudio.com/) provides a very simple API
for recording and/or playing sound using a simple callback function or
a blocking read/write interface. It is required for the audio processing
Computational geometry library (http://www.qhull.org). Qhull is
required to provide the functions
QR factorization updating library
(https://sourceforge.net/projects/qrupdate). QRUPDATE is used to
provide improved performance for the functions
Source code highlighter and manipulator; a Qt port of Scintilla (http://www.riverbankcomputing.co.uk/software/qscintilla). QScintilla is used for syntax highlighting and code completion in the GUI.
GUI and utility libraries (https://www.qt.io). Qt is required for
building the GUI. It is a large framework, but the only components
required are the GUI, core, and network modules. Since Octave 4.0, the
default graphics renderer (
"qt") has been Qt-based, which has
Sparse matrix factorization library (http://faculty.cse.tamu.edu/davis/suitesparse.html). SuiteSparse is required to provide sparse matrix factorizations and solution of linear equations for sparse systems.
The SUite of Nonlinear and DIfferential/ALgebraic Equation Solvers
(https://computation.llnl.gov/projects/sundials) is required for
the Ordinary Differential Equations (ODE) solvers
Data compression library (https://zlib.net). The zlib library is
required for Octave’s
save commands to handle
compressed data, including MATLAB v5 MAT files.
