Scilab

Scilab is a programming language associated with a rich collection of numeric algorithms for covering most aspects of computational and scientific problems.

Cloning

Cloning the Scilab repository. It is a large project - you will be downloading over 300MB of code.

Git

$ git clone git://git.scilab.org/scilab

Compiling

After cloning the git repository, a good approach for installing the required dependencies is:

$ sudo apt-get build-dep scilab

or

$ sudo aptitude build-dep scilab

After that,

$ ./configure

Probably there will be a couple of dependencies which are required to be more recent than the installed one. Look around the internet for them.

For the master branch, I had problems with libjgraphx (latest one was not available in Ubuntu 11.10).

• Download it from official site.
• Extract and enter jgraphx/lib/

$ sudo cp jgraphx.jar /usr/share/java/jgraphx-1.9.2.5.jar
$ sudo ln -sf /usr/share/java/jgraphx-1.9.2.5.jar /usr/share/java/jgraphx.jar

The master branch also asked for updated flexdock >= 0.5.3, jrosetta and jlatexmath. The graphic branch asked for scirenderer:

• Download them from
  • http://java.net/projects/flexdock/downloads
  • http://dev.artenum.com/projects/JRosetta
  • http://forge.scilab.org/index.php/p/jlatexmath
  • http://forge.scilab.org/index.php/p/scirenderer
• The remaining steps are like those given above for jgraphx.

If configure complains of missing arpack, download from the link shown by configure, then compile and install it as usual. Type 'ldconfig' and then get back to compiling Scilab. If there is still any problems related to arpack/arpack-ng, try the dirty fixes in these bug reports:

• http://bugzilla.scilab.org/show_bug.cgi?id=10646
• http://forge.scilab.org/index.php/p/arpack-ng/issues/689/ (comment 1)

If configure complains of missing jogl2, this is a recently introduced problem in Scilab master branch. See

• http://bugzilla.scilab.org/show_bug.cgi?id=11030

Finally,

$ make 
$ sudo make install

Build the documentation

$ make doc 

Warning: this takes a long time! go sip a cup of acerola juice while you wait.

If the run scilab this error appears on the screen:

"Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap","

To fix, do this:

$ sudo apt-get install gtk2-engines-pixbuf

Warning!

If you switch branches, e.g. from 5.3 and master (6.0), and then type 'make', you will obtain some crazy random errors; do not forget to type 'make distclean' after every branch switch ans start it *all* again.

Examples

• The Scilab package Chaos
  • site da distribuição.
• SIP image processing toolbox

Hacking

Navigating the souce code

• See the code organization at: http://doxygen.scilab.org/master_wg/

Branches

• We work at the master branch (future 5.4), but you can try YaSp (future 6.x)
• See a description of the branches [1]

Debugging e Profiling

See Debugging Scilab 5 at the Scilab wiki

They suggest KDbg as a graphical debugger, but it doesn't seem to be in synaptic. Therefore, ddd continues to be the best graphical debugger in our opinion.

Also see some useful kcachegrind tips in User:v1z's blog.
