During the compiling of scilab, the compile process attempts to invoke scilab several times and errors with "Gtk-WARNING **: cannot open display:" I initially tried to install scilab while logged into X as a non-root user where root didn't have access to the display. I ended up with a borked program that still ran but was unusable. I'm running gentoo-dev-sources-2.6.1 which has caused problems with some other ebuilds, but not sure if that is the case here.

apps that try to access the X display should be patched to not attempt that
Correct! I have wondered for months why I usually get a botched scilab that won't open help or demos, but occaisionally get a working one. As I normally compile such things from a script while remotely logged in / su'd, there is no X available -- recompilation with a display available cured the problem. The following is the result of opening a badly compiled scilab, then pressing the help and the demo buttons. Nothing more happens... Interestingly, the same problem exists even when installing binary or source versions from Inria; presumably it is some library that is messed up? _________________________________________________________ ========== scilab-2.7 Copyright (C) 1989-2003 INRIA/ENPC ========== Startup execution: loading initial environment load('SCI/macros/mtlb/lib') !--error 241 File SCI/macros/mtlb/lib does not exist or read access denied at line 50 of exec file called by : exec('SCI/scilab.star',-1);;quit -->help(); !--error 4 undefined variable : help -->exec('SCI/demos/alldems.dem'); num=x_choose(demolist(:,1),['Click to choose a demo'; !--error 4 undefined variable : demolist at line 16 of exec file called by : exec('SCI/demos/alldems.dem'); --> ___________________________________________________
-r3 will provide a virtual X server during build - this should fix the problem. Please test when available, re-open this bug if there are problems.
Scilab compiles flawless. Thanks!
