It is very recommended that you build Octave in a separate directory tree from the sources. | |||
For convenience we recommend a subdirectory to the main octave directory. | |||
For example, after you finished running the bootstrap script (takes a few secondds), run the | |||
following commands to create a build tree, configure, and build Octave: | |||
$ mkdir octave_build_directory | |||
$ cd octave_build_directory | |||
$ ../configure | |||
Running configure will take about half a minute. After it's finished, and if you are satisfied with | |||
the result, just run make | |||
$ make | |||
Building octave will take something on the scale of hours, | |||
the exact ammount depending on if the programmers or cpu engineers are ahead in the eternal race of performance versus cruft. | |||
The best thing to do is to leave it over lunch, or possibly overnight if it's late. You probably should sleep more anyway Jonathan. | |||

The [http://www.gnu.org/software/octave/doc/interpreter/External-Packages.html manual] lists the following as required packages: | |||
BLAS | |||
Basic Linear Algebra Subroutine library (http://www.netlib.org/blas). Accelerated BLAS libraries such as ATLAS (http://math-atlas.sourceforge.net) are recommeded for better performance. | |||
LAPACK | |||
Linear Algebra Package (http://www.netlib.org/lapack). | |||
PCRE | |||
The Perl Compatible Regular Expression library (http://www.pcre.org). | |||
The following external package is optional but strongly recommended: | |||
GNU Readline | |||
Command-line editing library (www.gnu.org/s/readline). | |||
