How do I get octave & PDFLatex to work for the Sage virtual machine?

[Brenton]

Hi,

I am new to VirtualBox but I have Sage running running now through it but I haven't a clue how to get octave & pdflatex installed on this virtual machine. The OS of the virtual machine on which Sage is running is Ubuntu 32 bit. My PC is Windows 7 64 bit. I have Octave installed on my host OS (i.e., the Win 7 64 bit) and it is in my PATH environment variable. 

Thanks for your time,

Brenton

Hello,

First of all none of your windows program can be used from the virtual
machine.

To install any software inside the virtual machine:
- make internet available to the virtual machine
- use the package manager to install new packages, in your cases the
packages are: "octave" and "texlive" (look over internet on how to do or
use "apt-get install octave texlive" in a console)

I can't seem to open up anything but Chromium (through which I am viewing the sage notebook). How do I open up a terminal? I've tried Ctrl+Alt+T, Alt+T, Shift+Alt+T with no effect. 

[Vincent Delecroix]

Ho, I see. You are using the virtual box from sagemath.org. Then you can try

(not sure it will work though)

I managed to install both pieces of software, although oddly now Sage notebook is having trouble starting octave & doesn't recognize that PDFLatex has been installed. I ran these commands through the terminal: 

sudo "yum install octave texlive"

as Sage 6.6 seems to run through Cent OS even though I set the OS for the virtual machine (VM) to Ubuntu (32 bit). I then closed the VM and re-opened & re-ran these commands. Attached is a screenshot showing my exact errors in sage notebook relating to PDFLatex & Octave.

Could you click on the left where the error message appear and
copy/paste here the full traceback of the error.

Here it is:

In a sage worksheet what happens if you evaluate a cell with

octave(1)

It seems that octave is not installed in your virtual machine. Did you
install it? If it is so, try in a console

octave --version

Vincent

[Brenton]

Gives

-bash: octave: command not found.

[Vincent Delecroix]

Then octave is not installed... how did you try to install it?

[Brenton]

I've tried installing it twice now. The basic procedure is I go into shell (Ctrl+F1), then login as either sage or root (1st time I used sage, 2nd as root), then run:

yum install octave texlive

clicking "Y" (for yes) when prompted. 

[Brenton]

I re-ran octave --version after my 2nd installation attempt and it gave the error in the attached screenshot.

Seems to be a known issue with CentOS

https://bugzilla.redhat.com/show_bug.cgi?id=872781

but solvable though. You should have a look on google "CentOS octave".

If you do solve the issue, please post your solution here! That would be
helpful!

Vincent

[Volker Braun]

did you try "yum install hdf5"?

[Brenton]

I have now. Octave still isn't working inside Sage.
