Bonjour à tous,
je rencontre un problème avec l'installation de scilab.

Chaque fois que j'essai de l'installer j'obtient cette erreur :
Code:
which: no scilab in (/usr/local/sbin:/sbin:/usr/sbin:/usr/lib/portage/bin:/usr/local/bin:/bin:/usr/bin:/opt/bin:/usr/i686-pc-linux-gnu/gcc-bin/4.1.1:/opt/blackdown-jdk-1.4.2.03/bin:/opt/blackdown-jdk-1.4.2.03/jre/bin:/usr/kde/3.5/sbin:/usr/kde/3.5/bin:/usr/qt/3/bin)
which: no g77 in (/usr/local/sbin:/sbin:/usr/sbin:/usr/lib/portage/bin:/usr/local/bin:/bin:/usr/bin:/opt/bin:/usr/i686-pc-linux-gnu/gcc-bin/4.1.1:/opt/blackdown-jdk-1.4.2.03/bin:/opt/blackdown-jdk-1.4.2.03/jre/bin:/usr/kde/3.5/sbin:/usr/kde/3.5/bin:/usr/qt/3/bin)
 * No fortran compiler found on the system!
 * Please add fortran to your USE flags and reemerge gcc!

!!! ERROR: sci-mathematics/scilab-2.7-r3 failed.
Call stack:
  ebuild.sh, line 1562:   Called dyn_setup
  ebuild.sh, line 665:   Called pkg_setup
  scilab-2.7-r3.ebuild, line 41:   Called die

!!! (no error message)
!!! If you need support, post the topmost build error, and the call stack if relevant.


La première fois je me suis dit j'ai du oublié fortran à gcc donc je vérifie et :
Code:
[ebuild   R   ] sys-devel/gcc-4.1.1  USE="fortran gtk nls (-altivec) -bootstrap -build -doc -gcj (-hardened) -ip28 -ip32r10k -mudflap (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla"


Donc gcc est bien compilé avec le USE fortran. Serait-ce un problème d'incompatibilité avec gcc 4.1 ?
Merci d'avance.

Salut, c'est effectivement possible que ça vienne de gcc 4.1
Mais je remarque aussi que tu essayes de compiler scilab 2.7 alors que le 4.0 est déjà dans portage (peut-être en ~arch). Tu devrais peut etre essayer de compiler un scilab plus récent.

Salut,

Explication (Bug #125203) :
Quote:

scilab ebuilds only checks for g77 fortran compiler, while gcc4 calls it
gfortran.

Quote:

cosidering that scilab 3 is pretty old and that's scilab 4 with a long
changelog

(http://www.scilab.org/download/features/scilab40.php)

it should be better to bump to 4 and test it.

i guess 3 series it unmainteined upstream too, so they won't help wioth gcc 4.x

bump to 4 and i'll be happy to test


Donc, oui, essaye la version 4.
