Re: Problems while installing Octave 4.2

[S. Swayamjyoti]

Hi, I am able to install the latest version of octave 4.4, in my system.

However, some of the packages are probably still not there in Octave 4.4. For example, when I call the function trainAutoEncoder, I get the following error. In MATLAB, this could be due to an older version. However, what can I do in Octave for that?

error: 'trainAutoencoder' undefined near line 25 column 7
error: called from
    ae at line 25 column 5

Hi,

Based on your suggestions, I installed Octave 4.4 in my system, I am able to install the dependancies, configure. But while building it with 'make', I get the following errors,

Hi,

I am trying to install an octave package for scientific computations. I could easily install Octave 4.0, but I am facing great difficulty, with Octave 4.2. After running the 'configure' command, successfully, I am still not able to find a make file to build Octave.

Can someone please help me with this? The issue is a bit urgent. Please find attached the error screenshot.

Best,

Swayam

You got an answer from Andreas Weber. Why you don't follow his advice?

I have a problem installing or upgrading to Octave 4.2.0. Could you help me on it?

GNU Octave 4.4.1 is the current stable version.

Inside, the Octave 4.2 folder, I just can't do a 'make' after, 'configuration'.

I guess you are trying to build Octave 4.2 from source on a GNU/Linux system which you shouldn't do unless you have good reasons.

Instead use the packages of your used distribution:
https://www.gnu.org/software/octave/download.html

or even Flatpak if your distribution doesn't ship Octave >=4.2

Hope that helps, Andy

Hi Swayan,

here again the advice of Andreas:

I think it is clear what he meant. Do not try to build Octave from source, but use a package from your distribution or Flatpack.

Why do you not follow his advice? You tried again to build it from source.
