I am new to Eclipse. Having worked with XCode in C++, I believe all necessary developer tools are installed. I downloaded the MacOSX 64 bit version of Eclipse. I have tested gcc in terminal. I cannot get the canned hello world project to compile. cout and std are not resolved. However if I comment out the std & cout lines, a program in which variable i is incremented will run. The compile error is given as:
Symbol 'cout' could not be resolved
Symbol 'std' could not be resolved
Any help would be appreciated. Details are given below.
Thanks.

I faced the same problem today and I think it could be related with C++ Compiler. So, I downloaded Dev-C++ and created the same .cpp project. After compile and execute, the problem has been solved. You can try.
Afterwards, I consider how to linked Dev-C++ compiler with Eclipse together, may add preferences.
Let's discuss!
