I wrote a wrapper to ignore --gui hardcoded option but also if it starts, it then fails to slice and / or place objects on the plate. Is there any planned release? This is my code, if you want to try
#!/bin/bash
command=""
for i in "$@"
do
case "$i" in
--gui)
;;
*)
command+="$i "
;;
esac
done
DIR=$(readlink -f "$0" | xargs dirname)
export LD_LIBRARY_PATH="$DIR/bin"
$DIR/bin/slic3r $command
