Re: Octave 3.8.2 install and Initial build on Fedora 21, 3.19.5-200.fc21.x86_64.

Hi,

        Has anyone got any ideas? See below for some analysis.

Hi,

         Just a quick note: gnuplot manages to plot the file OK, using the function plot.

Don't know if the helps, but it didn't make any difference re-installing 3.8.2, there is no other version able to yum, so I'm stuck with 3.8.2. Unless you know of a Tar ball somewhere (the ftp site is off line).

Thanks in advance for any help given!

Roger.

Hi, 

         I believe I have install all the packages, but it's still crashing when calling plot(). Even with a minimal

program, e.g.

ecg,txt, single column of length 1000:

-0.06

-0.065

...

load "ecg.txt"

y=ecg(1:999,1);

y

-0.06

-0.065

etc...

plot(y); 

crashed!

Would stepping back a version help, if so which version? Is there a stable Fedora Linux build?

Hi,

octave:4> graphics_toolkit

ans = fltk

$uname -r

3.19.5-200.fc21.x86_64

I'm now trying to install the packages.

$sudo yum install octave.*

Hi,

     I have just install Octave onto my Laptop "sudo yum install octave", which was successful. So, now I have >octave -v = GNU Octave 3.8.2

I have download some ecg data and created a single column file with the data, out.txt.

I can load it.

> load "out.txt";

>

>x=out(1:1000,1);

>

>x

x =

-0.06000

-0.06500 etc ...

>plot(x);

Panic: Segmentation fault -- Stopping myself...

attempting to save variables to 'octave-workspace'...

save to 'octave-workspace' complete

Segmentation fault (core dumped)

[ ]$

The plot brings up a GUI, but crashes soon after.

Any ideas?
