I just installed Eclipse and the first piece of code I've written the #include <iostream> command is marked for syntax error.

OS: Win7
toolchain: Unsure, the dropdown in the properties window is blank and greyed out.

It seems to me that you have not built the executable (hammer icon on top bar). See attached image.

index.php/fa/19006/0/

If it does not work, check from the MinGW console (another attached image) that the C++ compiler (g++) exists. There is also a run of your code on the console capture.
