Octave and Scilab.

Status
Not open for further replies.
yup got them emerged atm

Octave is just as good, it lacks some of the specific commands (stats stuff in detail) but I dont need that kind of stuff

The main use for me of Matlab/Octave is data manipulation (filtering,RMSing of recorded data)

I tried Scilab and unfortunatly SimuLink is far too advance for it to be of any use
 
trouble with cygwin.

I downloaded octave and am running it in windows using cygwin.

I tried the ./compile and got a few warning which were non fatal.

When I ran ./make, I got an error saying something about "could not stat octave-bug"

it is stat not start.. ??? :?:

Styx, how did you manage to install?

Please help.

Thank you in advance.
 
Well I run Linux:Gentoo as my primary operating system and it has the best package managment system called PORTAGE

Rather then installing BINARY programs (via RPM files or DEB files) Gentoo users download the source-code from the net and compile locally

most of the time it involves a

wget http:\\\URL-to_src.tar.gz
targ -uzt the-src.tar.gz
./configure
make
make install

this is automated in Gentoo so all we have to do is go emerge octave and it runs all those command to automatically install octave.

Saying that I have issued abt a dozen ebuilds myself to Portage so I know how they work

Here is the context of the ebuild for octage

from this it seems all that is needed are these 3 steps

./configure
make
make install

all done in the directory where the cource-code is.
what the ./configure does is checks yr setup to ensure all the libaries needed are present as well as a working compiler. This creates abt a dozen files that tell "make" what to do.
 
./configure took about 5 minutes and went on fine.

make took half an hour and ended up as gcc : fork forbidden or something simsilar and the wholw thing went into the recycle bin. :( :cry:

I shall try extracting the source from my saved ZIP file again and try it all over again... Hope it works...

Initially I had to run the cygwin setup several times to get each of the package it kept asking for...

yer there are a few dependacies with Octave

from the EBUILD file (this list all the deps)
DEPEND="virtual/libc
>=sys-libs/ncurses-5.2-r3
>=media-gfx/gnuplot-3.7.1-r3
>=sci-libs/fftw-2.1.3
>=dev-util/gperf-2.7.2
zlib? ( sys-libs/zlib )
hdf5? ( sci-libs/hdf5 )
tetex? ( virtual/tetex )
x86? ( ifc? ( dev-lang/ifc ) )
blas? ( virtual/blas )
!=app-text/texi2html-1.70"

not to mention GCC
