Odd, works for me. Exactly what version of kobuki and ecl are you compiling against?

for me:

same. But remember I compile without calling catkin nor yujin tools

cd ~/kobuki_ws/build KOBUKI_DRIVER_LOCATION=../install KOBUKI_DRIVER_PACKAGES="sed -n -e ":a" -e "$ s/\n/;/gp;N;b a" ../src/kobuki/kobuki_driver/catkin_whitelist" cmake ../src -DCATKIN_WHITELIST_PACKAGES=$KOBUKI_DRIVER_PACKAGES -DCMAKE_INSTALL_PREFIX=$KOBUKI_DRIVER_LOCATION make

Somehow I was linking against groovy installed libraries instead of against the newly compiled. Removing ros-groovy-ecl-xxxx clean-make again fixed the problem.
