Installation problem - System environment

Hello,

I also have a Gutsy on my laptop and have successfully installed open cascade. I don't have csh and ksh, but bash. So I wrote an equivalent initialisation script of open cascade in bash, here it is :

#!/bin/bash
export CASROOT=/opt/lib/occ6.2.0/ros
OS_NAME=`uname`
export PATH="$CASROOT/../3rdparty/$OS_NAME/tcltk/bin:$CASROOT/$OS_NAME/bin:$PATH"
export LD_LIBRARY_PATH="$CASROOT/../3rdparty/$OS_NAME/tcltk/lib:$CASROOT/$OS_NAME/lib:$LD_LIBRARY_PATH"

export CSF_MDTVFontDirectory=$CASROOT/src/FontMFT
export CSF_LANGUAGE=us
export MMGT_CLEAR=1
export CSF_EXCEPTION_PROMPT=1
export CSF_SHMessage=$CASROOT/src/SHMessage
export CSF_MDTVTexturesDirectory=$CASROOT/src/Textures
export CSF_XSMessage=$CASROOT/src/XSMessage
export CSF_StandardDefaults=$CASROOT/src/StdResource
export CSF_PluginDefaults=$CASROOT/src/StdResource
export CSF_XCAFDefaults=$CASROOT/src/StdResource
export CSF_StandardLiteDefaults=$CASROOT/src/StdResource
export CSF_GraphicShr=$CASROOT/$OS_NAME/lib/libTKOpenGl.so
export CSF_UnitsLexicon=$CASROOT/src/UnitsAPI/Lexi_Expr.dat
export CSF_UnitsDefinition=$CASROOT/src/UnitsAPI/Units.dat
export CSF_IGESDefaults=$CASROOT/src/XSTEPResource
export CSF_STEPDefaults=$CASROOT/src/XSTEPResource
export CSF_XmlOcafResource=$CASROOT/src/XmlOcafResource

export TCLHOME=$CASROOT/../3rdparty/$OS_NAME/tcltk
export TCLLIBPATH=$TCLHOME/lib
case $OS_NAME in
"SunOS")
export TIX_LIBRARY=$TCLLIBPATH/tix8.1;;
esac

export ITK_LIBRARY=$TCLLIBPATH/itk3.2
export ITCL_LIBRARY=$TCLLIBPATH/itcl3.2
export TK_LIBRARY=$TCLLIBPATH/tk8.4
export TCL_LIBRARY=$TCLLIBPATH/tcl8.4

Replace the value of the variable CASROOT with the right folder for your case.
Once done, open a terminal and type "source /yourfolder/env.bsh" then you can use open cascade for your development.
Note : add "source /yourfolder/env.bsh" to ~/.bashrc (this is your shell rc file) so open cascade is fully configured on startup.
