C++ compiling error: unrecognized command line option "-std=c++11"

Question

I am using g++ version 4.8.5. I am trying to compile my project using it. It compiles without a problem, when compiling directly from the terminal. But, when using a make file, it gives me following error, even though I am using the same option.

cc1plus: error: unrecognized command line option "-std=c++11"

What am I doing wrong here ?

Edit: as requested, here's my makefile line:

main: main.cc
    @g++ -std=c++11 main.cpp -o run

@solti Ah, I didn't know about that. Why do I need to have two dashes ? — ThisaruG

You don't, -std=c++11 is a correct compiler switch for C++11 — krzaq

Hmm, have you tried specifying g++'s absolute path? Something like this: @/usr/bin/g++-4.8 -std=c++11 main.cpp -o run — Martin Jungblut Schreiner

@MartinJungblutSchreiner Thanks buddy. It worked. Problem was the path. When using absolute path, it compiled correctly. Thanks again. Can you put it as an answer ? I can accept that then. — ThisaruG

Try using g++'s absolute path:

main: main.cc
    @/usr/bin/g++-4.8 -std=c++11 main.cpp -o run
