octave: Build Tools

 
 E.1.2 Build Tools
 -----------------
 
 The following tools are required:
 
 C++, C, and Fortran compilers
      The Octave sources are primarily written in C++, but some portions
      are also written in C and Fortran.  The Octave sources are intended
      to be portable.  Recent versions of the GNU compiler collection
      (GCC) should work (<http://gcc.gnu.org>).  If you use GCC, you
      should avoid mixing versions.  For example, be sure that you are
      not using the obsolete ‘g77’ Fortran compiler with modern versions
      of ‘gcc’ and ‘g++’.
 
 GNU Make
      Tool for building software (<http://www.gnu.org/software/make>).
      Octave’s build system requires GNU Make.  Other versions of Make
      will not work.  Fortunately, GNU Make is highly portable and easy
      to install.
 
 AWK, sed, and other Unix utilities
      Basic Unix system utilities are required for building Octave.  All
      will be available with any modern Unix system and also on Windows
      with either Cygwin or MinGW and MSYS.
 
    Additionally, the following tools may be needed:
 
 Bison
      Parser generator (<http://www.gnu.org/software/bison>).  You will
      need Bison if you modify the ‘oct-parse.yy’ source file or if you
      delete the files that are generated from it.
 
 Flex
      Lexer analyzer (<http://www.gnu.org/software/flex>).  You will need
      Flex if you modify the ‘lex.ll’ source file or if you delete the
      files that are generated from it.
 
 Autoconf
      Package for software configuration
      (<http://www.gnu.org/software/autoconf>).  Autoconf is required if
      you modify Octave’s ‘configure.ac’ file or other files that it
      requires.
 
 Automake
      Package for Makefile generation
      (<http://www.gnu.org/software/automake>).  Automake is required if
      you modify Octave’s ‘Makefile.am’ files or other files that they
      depend on.
 
 Libtool
      Package for building software libraries
      (<http://www.gnu.org/software/libtool>).  Libtool is required by
      Automake.
 
 gperf
      Perfect hash function generator
      (<http://www.gnu.org/software/gperf>).  You will need gperf if you
      modify the ‘octave.gperf’ file or if you delete the file that is
      generated from it.
 
 Texinfo
      Package for generating online and print documentation
      (<http://www.gnu.org/software/texinfo>).  You will need Texinfo to
      build Octave’s documentation or if you modify the documentation
      source files or the docstring of any Octave function.
