Reproduce this error by running: ==> cd /home/dinesh/ws/underlay_isolated/build_isolated/rtt && /home/dinesh/ws/underlay_isolated/install_isolated/env.sh make -j4 -l4

Command failed, exiting.

AFtr i enter command "catkin_make_isolated --install -DENABLE_CORBA=ON -DCORBA_IMPLEMENTATION=TAO" i'm getting above error. I'm using ubuntu 16.04.

Try to change CorbaType* result; to const CorbaType* result; on line 259 of rtt/rtt/transports/corba/CorbaConversion.hpp
