What does your launch file look like? Sounds like an environment or installation issue

This definitely looks like a workspace setup issue. The packages hector_mapping, hector_trajectory_server and hector_geotiff cannot be found by ROS's package utilities. You can verify this by trying

roscd hector_mapping

This command will very likely also fail. You'll have to make sure all packages can be found and are in one of the subfolders specified by the ROS_PACKAGE_PATHenvironment variable.

hi stefan I actually downloaded the source code from github and then copy pasted it in src folder of my ros wrkspace.Maybe thats the reason its not wrking. Shud i try this then sudo apt-get install ros-indigo-hector-slam

That definitely is the easier option (and should be working).
