Here is the procedure for installing Octave from scratch on a Unix system. For instructions on how to install the binary distributions of Octave, see section Binary Distributions.

--enable-lite-kernelel
or the dynamic loading features, you will
probably want to use this option. It will make your `.oct' files
much smaller and on some systems it may be necessary to build shared
libraries in order to use dynamically linked functions.
You may also want to build a shared version of libstdc++
, if your
system doesn't already have one. Note that a patch is needed to build
shared versions of version 2.7.2 of libstdc++
on the HP-PA
architecture. You can find the patch at
@url{ftp://ftp.cygnus.com/pub/g++/libg++-2.7.2-hppa-gcc-fix}.
--enable-dl
dlopen
and friends to make Octave capable of dynamically
linking externally compiled functions. This only works on systems that
actually have these functions. If you plan on using this feature, you
should probably also use --enable-shared
to reduce the size of
your `.oct' files.
--enable-shl
shl_load
and friends to make Octave capable of dynamically
linking externally compiled functions. This only works on systems that
actually have these functions (only HP-UX systems). If you plan on
using this feature, you should probably also use --enable-shared
to reduce the size of your `.oct' files.
--enable-lite-kernel
dlopen
or shl_load
and friends so that Octave
can load functions at run time that are not loaded at compile time.
--help
g++
2.7.2 or later. Version 2.8.0 or egcs
1.0.x should work. Later versions may work, but C++ is still evolving,
so don't be too surprised if you run into some trouble.
It is no longer necessary to have libg++
, but you do need to have
the GNU implementation of libstdc++
. If you are using g++
2.7.2, libstdc++
is distributed along with libg++
, but for
later versions, libstdc++
is distributed separately. For
egcs
, libstdc++
is included with the compiler
distribution.
If you plan to modify the parser you will also need GNU bison
and
flex
. If you modify the documentation, you will need GNU
Texinfo, along with the patch for the makeinfo
program that is
distributed with Octave.
GNU Make, gcc
, and libstdc++
, gnuplot
,
bison
, flex
, and Texinfo are all available from many
anonymous ftp archives. The primary site is @url{ftp.gnu.org}, but it
is often very busy. A list of sites that mirror the software on
@url{ftp.gnu.org} is available by anonymous ftp from
@url{ftp://ftp.gnu.org/pub/gnu/GNUinfo/FTP}.
If you don't have a Fortran compiler, or if your Fortran compiler
doesn't work like the traditional Unix f77, you will need to have the
Fortran to C translator f2c
. You can get f2c
from any
number of anonymous ftp archives. The most recent version of f2c
is always available from @url{netlib.att.com}.
On an otherwise idle Pentium 133 running Linux, it will take somewhere
between 1-1/2 to 3 hours to compile everything, depending on whether you
are building shared libraries. You will need about 100 megabytes of disk
storage to work with (considerably less if you don't compile with debugging
symbols). To do that, use the command
make CFLAGS=-O CXXFLAGS=-O LDFLAGS=instead of just `make'.
This section contains a list of problems (and some apparent problems that don't really mean anything is wrong) that may show up during installation of Octave.
info
fails to compile if
HAVE_TERMIOS_H
is defined int `config.h'. Simply removing
the definition from `info/config.h' should allow it to compile.
configure
finds dlopen
, dlsym
, dlclose
,
and dlerror
, but not the header file `dlfcn.h', you need to
find the source for the header file and install it in the directory
`usr/include'. This is reportedly a problem with Slackware 3.1.
For Linux/GNU systems, the source for `dlfcn.h' is in the
ldso
package.
libstdc++
. A patch
is needed to build shared versions of version 2.7.2 of libstdc++
on the HP-PA architecture. You can find the patch at
@url{ftp://ftp.cygnus.com/pub/g++/libg++-2.7.2-hppa-gcc-fix}.
options GPL_MATH_EMULATErather than
options MATH_EMULATEin the kernel configuration files (typically found in the directory `/sys/i386/conf'. After making this change, you'll need to rebuild the kernel, install it, and reboot.
passing `void (*)()' as argument 2 of `octave_set_signal_handler(int, void (*)(int))'or
warning: ANSI C++ prohibits conversion from `(int)' to `(...)'while compiling `sighandlers.cc', you may need to edit some files in the
gcc
include subdirectory to add proper prototypes for functions
there. For example, Ultrix 4.2 needs proper declarations for the
signal
function and the SIG_IGN
macro in the file
`signal.h'.
On some systems the SIG_IGN
macro is defined to be something like
this:
#define SIG_IGN (void (*)())1when it should really be something like:
#define SIG_IGN (void (*)(int))1to match the prototype declaration for the
signal
function. This
change should also be made for the SIG_DFL
and SIG_ERR
symbols. It may be necessary to change the definitions in
`sys/signal.h' as well.
The gcc
fixincludes
and fixproto
scripts should
probably fix these problems when gcc
installs its modified set of
header files, but I don't think that's been done yet.
You should not change the files in `/usr/include'. You
can find the gcc
include directory tree by running the command
gcc -print-libgcc-file-nameThe directory of
gcc
include files normally begins in the same directory
that contains the file `libgcc.a'.
makeinfo
program that is distributed with
Texinfo (through version 3.9) that causes the indices in Octave's
on-line manual to be generated incorrectly. If you need to recreate the
on-line documentation, you should get the makeinfo
program that
is distributed with texinfo-3.9 and apply the patch for makeinfo
that is distributed with Octave. See the file `MAKEINFO.PATCH' for
more details.

_tcgetattr _tcsetattr _tcflowwhich are part of `libposix.a'. Unfortunately, linking Octave with
-posix
results in the following undefined symbols.
.destructors_used .constructors_used _objc_msgSend _NXGetDefaultValue _NXRegisterDefaults .objc_class_name_NXStringTable .objc_class_name_NXBundleOne kluge around this problem is to extract `termios.o' from `libposix.a', put it in Octave's `src' directory, and add it to the list of files to link together in the makefile. Suggestions for better ways to solve this problem are welcome!
octave_ieee_init
in
the file `lo-ieee.cc' to correctly initialize Octave's internal
infinity and NaN variables.
If your system does not support IEEE arithmetic but Octave's configure
script incorrectly determined that it does, you can work around the
problem by editing the file `config.h' to not define
HAVE_ISINF
, HAVE_FINITE
, and HAVE_ISNAN
.
In any case, please report this as a bug since it might be possible to
modify Octave's configuration script to automatically determine the
proper thing to do.
run-octave
doesn't work. Emacs
hangs in accept-process-output
in inferior-octave-startup
.
This seems to be a problem with executing a shell script using the
comint package. You can avoid the problem by changing the way Octave is
installed to eliminate the need for the shell script. You can either
compile and install Octave using the source distribution, reinstall the
binary distribution in the default directory, or copy the commands in
the octave shell script wrapper to your shell startup files (and the
shell startup files for anyone else who is using Octave) and then
rename the file `octave.bin' to be `octave'.
Although Octave is not very difficult to build from its sources, it is a relatively large program that does require a significant amount of time and disk space to compile and install. Because of this, many people want to be able to obtain binary distributions so they can start using Octave immediately, without having to bother with the details of compiling it first. This is understandable, so I try to maintain a current collection of binary distributions at @url{ftp://ftp.che.wisc.edu/pub/octave/BINARIES}.
Please understand, however, that there is only a limited amount of time available to devote to making binaries, so binaries may not be immediately available for some platforms. (Please contact @email{bug-octave@bevo.che.wisc.edu} if you are interested in helping make a binary distribution available for your system.)
To install Octave from a binary distribution, execute the command
sh ./install-octave
in the top level directory of the distribution.
Binary distributions are normally compiled assuming that Octave will be installed in the following subdirectories of `/usr/local'.
where version stands for the current version number of the interpreter, and arch is the type of computer on which Octave is installed (for example, `i586-pc-linux-gnu').
If these directories don't exist, the script install-octave
will
create them for you. The installation script also creates the following
subdirectories of `/usr/local' that are intended for locally
installed functions:
If it is not possible for you to install Octave in `/usr/local', or if you would prefer to install it in a different directory, you can specify the name of the top level directory as an argument to the `install-octave' script. For example:
sh ./install-octave /some/other/directory
will install Octave in subdirectories of the directory `/some/other/directory'.
Here is how to build a binary distribution for others to use. If you want to make a binary distribution for your system available along with the Octave sources and binaries on @url{ftp.che.wisc.edu}, please follow this procedure. For directions explaining how to make the binary available on the ftp site, please contact @email{bug-octave@bevo.che.wisc.edu}.
gunzip -c octave-2.0.13.tar.gz | tar xf -
cd octave-2.0.13
make binary-distThis will create a compressed tar file ready for distribution. It will have a name like `octave-2.0.13-i586-pc-linux-gnu.tar.gz'
