Thanks a lot for replying. i did what u asked me to do. following is the result After doing make wipe and make, i get the following output You have OGRE 1.6 locally, making a soft link to the system version. I had ogre3d installed on the system before but i did make clean in my previously ogre3d installation and then manually deleted the files/folder which were still there after make clean. I think my inode still has ogre3d in it and that is why it is not letting ROS to build ogre on its own.
