Scilab in Fedora GNU/Linux
Filed under: 
aving encountered problems with Octave in Fedora 14, I decided to explore scilab, which I wanted to try about a week ago anyway (and canceled the process after being warned that it was not as complete as octave, at least not for my needs). Fedora does not appear to have scilab in its repositories (Ubuntu on the other hand does have it). A yum and kpackagekit search around “scilab” yields nothing, so I went to the official scilab Web site and downloaded the latest package from that nice Web site, then uncompressed it. This was not the end of it as far as Fedora was concerned because, due to it not being available in the repositories, dependencies could not be resolved, so I needed to also install java manually, then figure out that SELinux was standing in my way. This is the type of thing which would deter new users and as much as I would love to endorse Fedora 14, it is experiences like this which leads me to saying that Kubuntu is still a better choice. Here is a self-explanatory story:

This worked the second time only because I made SELinux more permissive, but this could have many users give up. Here is what I then got:
As expected, there is no support for some fairly basic functions in scilab, which is not a complete octave replacement.
-->imshow('in')
!--error 4
Undefined variable: imshow
-->imread('in')
!--error 4
Undefined variable: imread
I do not want to install MATLAB or Fedora (although we do have an academic licence), but experiences with Fedora so far may drive me towards installing proprietary software or simply working from another box which happens to be better equipped and work perfectly well with Octave. That box runs Kubuntu.

Hello,
FYI, imshow & imread are provided by a Scilab extension
atomsInstall(‘sivp’) should do it.
There are also some work to see Scilab into Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=472639
but it still needs to have JoGL into Fedora before:

Sylvestre, thanks a lot. I’ll take another look. Some colleague of mine wants to move to Scilab.

OK, I finally got around to trying it. The command you suggested did not work even with the other quote symbol.
-->atomsInstall('sivp') atomsInstallList: The package sivp is not available. !--error 10000 at line 51 of function atomsError called by : at line 76 of function atomsInstallList called by : at line 217 of function atomsInstall called by : atomsInstall('sivp') -->atomsInstall("sivp") atomsDownload: The following file hasn't been downloaded: - URL : 'http://atoms.scilab.org/TOOLBOXES/32/linux.gz' - Local location : '/tmp/SD_21631_/.atoms/TOOLBOXES.gz' !--error 10000 at line 200 of function atomsDownload called by : at line 63 of function atomsGetTOOLBOXES called by : at line 213 of function atomsInstall called by : atomsInstall("sivp")I then tries installing it manually by downloading the package and following the instructions. That too did now have the toolbox installed (I cannot find it in the GUI). It just doesn’t seem to get me to the point where I can use im* functions.
Package opencv was not found in the pkg-config search path. error(gettext("OpenCV (version >= 1.0.0) is needed for compiling SIVP.")); !--error 10000 OpenCV (version >= 1.0.0) is needed for compiling SIVP. at line 72 of exec file called by : at line 10 of function tbx_builder_gateway_lang called by : tbx_builder_gateway_lang(languages, sci_gateway_dir); at line 6 of exec file called by : at line 8 of function devtools_run_builder called by : at line 6 of function tbx_builder_gateway called by : tbx_builder_gateway(toolbox_dir); at line 35 of exec file called by : exec('builder.sce')July 18th, 2012 at 6:48 pm
FYI, it is not atomsInstall(‘sivp’) but atomsInstall(‘SIVP’) , i.e., case-sensitive toolbox name.

I am having the same problem but I actually have loaded SIVP. I still get Undefined variable: imread .
This is what happens when I installed SIVP: atomsInstall(“SIVP”)
Scanning repository http://atoms.scilab.org/5.5 … Done
ans =
!SIVP 0.5.3.2-1 allusers SCI\contrib\SIVP.5.3.2-1 I !
included in case there is something wrong with this output. But then when I try imread command I get the undefined variable: imread.
