Hi
I have installed Eclipse and I am trying to run C++ programs using the cdt tool which I installed it from the update manager present in the eclipse itself.
But whenever I am trying to run a C++ program I am getting this error.

Error starting process
java.io.IOException: Exec_tty error:Cannot run /home/raghu/c/eclipse/workspace/first/Debug/first.o
