Shared installation (file access and permissions)

[coppelia]

Hello,

this is unfortunately not possible (for now). Best would be to adjust the settings for each user locally, then copy the system/usrset.txt file just before V-REP launch, in order to have differentiated settings depending on the users.

Cheers

Okay I did this now. Here is my Start Script:

#!/bin/sh

arch="`uname -m`"

system="/opt/vrep/shared/system"
tmpfolder="/tmp/vrep"
localsettings="$HOME/.vrep"
usrset="usrset.txt"
settings="settings.dat"
instances="instances"
usrsetdefault="$system/userset_default.txt"
settingsdefault="$system/settings_default.dat"



if [ "x86_64" = "$arch" ]; then
dirname="/opt/vrep/64"
elif [ "i686" = "$arch" ]; then
dirname="/opt/vrep/32"
else
dirname=""
fi


if [ "$dirname" != "" ]; then
if [ ! -e "$localsettings" ]; then
mkdir "$localsettings"
fi
if [ ! -e "$localsettings/$usrset" ]; then
cp "$usrsetdefault" "$localsettings/$usrset"
fi
if [ ! -e "$localsettings/$settings" ]; then
cp "$settingsdefault" "$localsettings/$settings"
fi
if [ ! -e "$tmpfolder" ]; then
mkdir "$tmpfolder"
cp "$localsettings/$usrset" "$tmpfolder/"
cp "$localsettings/$settings" "$tmpfolder/"
echo "1" > "$tmpfolder/$instances"
else
echo "One Instance of v-rep is already running on this machine. Do you want to use the same config?"
echo "Y/n"
read answer
if [ "n" = "$answer" ]; then
exit 0
fi
echo "$((`cat $tmpfolder/$instances` + 1))" > "$tmpfolder/$instances"
fi
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$dirname
export LD_LIBRARY_PATH
cd "$dirname"
"$dirname/vrep" "$@"
cp "$tmpfolder/$usrset" "$localsettings/$usrset"
cp "$tmpfolder/$settings" "$localsettings/$settings"
if [ "`cat $tmpfolder/$instances`" = "1" ]; then
rm -rf "$tmpfolder"
else
echo "$((`cat $tmpfolder/$instances` - 1))" > "$tmpfolder/$instances"
fi

else
echo "A not supported plattform is used. Please use a x86_64 or i686 Linux system."
fi

It includes also a switch for 32 and 64bit system because in our IT configuration both architectures are used with same opt mount. The 32 bit version of v-rep is placed in /opt/vrep/32 and the 64bit in /opt/vrep/64. I moved the system directory otuside of the architecture directories (/opt/shared/system) and linked it into the directories of both versions. Additionally, the setting files has to be moved to default versions and symlinks to the tmp directory has to be created.
