[Scilab-users] Installing Scilab under Linux (Mint / aka Ubuntu)

Hi there

I've installed Linux Mint 19 (MATE) and installing Scilab using the
Software Manager doesn't work. I cannot get the GUI to show up (CLI
works fine). There are several bug reports out there, but AFAIK no
remedy. P.S. Upon first installation I did check and see that the GUI
worked, but it never worked since and uninstalling + installing (incl.
the CLI, and BTW also including reboots) doesn't work.

Therefore I decided to download the Linux 64-bit package from scilab.org
... when unpacked, I see there's not an installer ... but as the README
says, launching ./bin/scilab gives me the GUI (yaayh!)

The question is - from unpacking the software, how am I supposed to
install this already compiled scilab in my Linux? ... Am I supposed to
leave it in my /home directory? ... Sorry for my lack of knowledge here.
I hope for some kind help.

Best regards,

Claus

Hello Claus,

I usually untar the scilab archive in a local folder in my home directory ("~/bin" for example) and I had the path to this folder in my $PATH variable.
To launch scilab, I open a terminal and just type "scilab" (or scilab-cli, or whatever version you want to use).
I don't have fancy integration with the desktop environment, but it works well that way...
Whenever I want to upgrade to a new version, I remove the folder and untar the new scilab version...

Hope it helps,

Antoine

Dear Claus!

As a temporarily fix you can read this solution on AskUbuntu -
https://askubuntu.com/a/1029164/66509 . I have tested it. Unpacking to home
folder works as expected (and as before).

Dear Scilab developers!

As long-time Scilab user I can't completely understand how this may happen.
Please take a look to the mentioned bugs in the linked answer above and
make real actions to fix these problems. Scilab is completely broken in
Ubuntu 18.04 LTS (so without real actions it will be broken until 2023) and
does not work on development version 18.10 too. Also it does not work on
Debian 10. Please contact Debian and/or Ubuntu maintainers directly.

Scilab is very often used in educational purposes. For example we use it on
Ubuntu 16.04 LTS in our university to teach students.
It will be very bad if we lose such a convenient and useful software-tool.

Hi Antoine and Nikolay

Thank you for your help. I see that the easiest way is, as Antoine
wrote, to execute a shell and execute scilab from the shell (and for
sure, keep the shell open).

I tried to create a desktop "launcher" in Linux Mint, executing a
scilab.sh script and containing 'nohup scilab.sh & disown' ... to
release scilab from the terminal, but at no luck.

I also tried to follow advice from askubuntu (below), including creating
desktop files, etc. (see near the bottom), but still no luck.

Best regards,
Claus

Hi Antoine and Nikolay
Thank you for your help. I see that the easiest way is, as Antoine
wrote, to execute a shell and execute scilab from the shell (and for
sure, keep the shell open).
Well, the best solution I found is to use a dropdown terminal (like
yakuake for example): pressing F12 the terminal appears/disappears. This
way, I never have to close it and it stays open with a bunch tabs with
the most common command line applications I use.

scilab.sh script and containing 'nohup scilab.sh & disown' ... to
release scilab from the terminal, but at no luck.
Well, I think the .desktop approach is the best one here.
You can also try to use a command launcher: with the Ubuntu I use
(16.04), I have Alt+F2 that opens a proper command launcher and I can
run any command line app. Note that it differs from pressing the Windows
key that will only launch applications that have a corresponding
*.desktop file.

I also tried to follow advice from askubuntu (below), including
creating desktop files, etc. (see near the bottom), but still no luck.
I don't see your attempt here.
If you installed scilab from the repos, you should have a *.desktop file
to tinker with in order to call your up-to-date scilab instead of the
repo one.
On my system the desktop files of the repos applications are here:

    /usr/share/app-install/desktop/scilab:scilab.desktop
    /usr/share/applications/scilab.desktop

while I put the one of the applications I installed by hand  here:

    ~/.local/share/applications/

Hope it helps,

Antoine
