running eclipse and getting a bunch of errors! HELP

[claudilla]

Hello,

Im making a program on eclipse(linux), and getting a bunch of errors...

type string couldn't be resolved
symbol std couldn't be resolved
unresolved inclusion <iostream>
invalid preprocessing directive #include
etc...

Does anyone know whats going on? I'm pretty sure it must be something with configuration..?? HELP!!!!!!

thanks.

Are you sure you are compiling the code as C++?

[claudilla]

Yes, i created a c++ project.

[Peter87]

I think you will have to post your real code and error message. Or does all C++ code fail to compile? Even a simple hello world program?

#include <iostream>

int main()
{
	std::cout << "Hello world!" << std::endl;
}

[claudilla]

All c++ code fail to compile..i just tried the hello world program..

Can you post the complete and exact list of errors you get? It might contain clues about what's going on.

Is GCC installed?

[claudilla]

How do i know if its installed?

[Peter87]

It depends on your distribution I guess but look for a package named g++ in the package manager. On Debian/Ubuntu I recommend you install the build-essential package if you haven't already.
