Firstly, I saw topics such as 'How to install manually a software...' but it did not solve my problem. I've downloaded Scilab 5.4.1 from the official website and I extracted the .tar.gz file into:


I then tried the commands below, but they gave several errors:

$ cd scalib-5.4.1
$ configure        @1
$ make             @2
$ make install     @3

these gave the following messages in the terminal:

@1: configure: command not found
@2: make: *** No targets specified and no makefile found.  Stop.
@3: make: *** No rule to make target `install'.  Stop.

I tried following commands:

$ cd scilab-5.4.1
$ cd bin
$ scilab

which gave the message:

The program 'scilab' is currently not installed.  You can install it
by typing: sudo apt-get install scilab

Ok, I just tried installing it, an it worked OK. Here what I did: To install, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo apt-get install scilab

After the installation was done, I searched for scilab in dash, and clicked on it

After I clicked on it, it opened, and I checked the version, and it was 5.4.1

Hope that helps.

You can also just download the version for linux and simply click the binary in scilab/bin/scilab. It should work.

Your terminal command should work, but with the following change:

$ cd scilab-5.4.1
$ cd bin
$ ./scilab

Note the "dot-slash" before "scilab". "Dot" is the current working directory. Your shell was looking for scilab in all of the directories in your PATH environment variable, and not finding it, suggested that you needed to install the package. Do:

echo $PATH

on the command line and you will see which directories are searched.

This is a really common mistake - after a while, including the dot-slash will be second nature. Note you can also include the path structure in the command line launch:

$ cd scilab-5.4.1
$ ./bin/scilab

Hope this helps.
