Can't find file executable in your configured search path for INTEL C++ compiler (Linux)

I want to debug my c++ code using code::blocks. I open a new project and paste my code. But there is above error. To be honest, I'm not sure what is my compiler! when I want to run my code, I write:

g++ -std=gnu++11 mycodename.cpp

in the terminal. How can I remove above error in Linux? A step by step answer is highly appreciated.
