Hello! Since scilab 5 is not yet in main and the ebuild in science overlay does not work for everyone (bug #237572), I try to use the binary provided by scilab.org. There are several packages with versions for 32- or 64-bit systems.

  • 4.1.2 (runs smoothly everywhere BUT it has an aging tcl/tk look, a keyboard-challenged input interface, reaches amazing high scores in powertop and has tendency to let zombie process eat 100 % cpu when not terminated properly),
  • 5.2.2 (current stable),
  • 5.3.0 beta 1.

Install procedure is the following:
Code:

~/ $ tar xfz scilab-5.2.2.bin.linux-x86_64.tar.gz # for example this version
~/ $ export LD_LIBRARY_PATH="~/scilab-5.2.2/bin"
~/ $ export SCI="~/scilab-5.2.2/share/scilab"
 
~/ $ ./scilab-5.2.2/bin/scilab
  or
~/ $ linux32 ./scilab-5.2.2/bin/scilab # running the i686 version on an amd64 arch through 32-bit emulation

Then happens the following:

  • scilab 4 works fine;
  • scilab 5, whichever version, crashes on almost anything, for example on displaying non integer numbers.

[Scilab prompt]
Code:

--> 1.0   // this works
--> 1.1 ; // this also works (no display after semicolon)
--> 1.1   // scilab crashes


When scilab crashes, the console from where it was launched reports
Code:
At line 27 of file src/fortran/formatnumber.f
Internal error: printf is broken

(Line number changes depending on scilab version, it is line 27 for 5.2.2, line 43 for the version 5.3.0 beta 1.)

I downloaded OpenSuse 11.2 livecds, 32 bits and 64 bits. Following the same install procedure, I am able to run all aforementioned versions of scilab and run complete calculations and graphs without problem. This means, somehow the problem comes from my gentoo box. Has anybody succeeded in using scilab 5 on gentoo from the binary packages (specially on amd64)?

Thanks for your time and suggestions.

Ecko

Hi ecko,

Scilab 5.2.0 works fine on my laptop (gentoo ~amd64) - I've just tested with some demos and they work, although you can get is the occasional null pointer exception in the terminal. Your tests also work, 1.0, 1.1 display fine.

Thanks, although this is a bit frustrating. I'll wait for the ebuild for scilab 5.3 so I can compile with debug output.

ecko, this is not a Scilab bug but a gcc one. Please see:

and

Hello Sylvestre,

Code:

$ LC_ALL="C" scilab


This solves the issue, thanks a lot for pointing that this is a localization problem! What about mentioning the solution in the release notes or somewhere else?
