make: Nothing to be done for `tolua++'.

when I binding the custom class using the tolua*+ tool. It show this.
my cocos2dx version is 2.2.1
build.sh file:
#!/bin/bash
#
# Invoked build.xml, overriding the lolua*+ property

SCRIPT_DIR=$(cd “$(dirname”${BASH_SOURCE[0]}“)” && pwd)
TOLUA=/Users/cgw/cocos2d-x/tools/tolua**/tolua**
if [ ~~z “${TOLUA}” ]; then
TOLUA=`which tolua5.1`
fi
if [ -z “${TOLUA}” ]; then
echo "Unable to find tolua
in your PATH."
exit 1
fi
cd ${SCRIPT_DIR}
${TOLUA}~~L basic.lua -o …/…/scripting/lua/cocos2dx_support/LuaCocos2d.cpp Cocos2d.pkg

makefile
…/…/scripting/lua/cocos2dx_support/LuaCocos2d.cpp: basic.lua *.pkg
./build.sh

command:
bogon:~ cgw$ cd /Users/cgw/cocos2d-x/tools/tolua*+
bogon:tolua*+ cgw$ make tolua*+
make: Nothing to be done for `tolua*+’.

using sudo ./build.sh instead of make tolua++。
