cannot compile simple hello world C++ program in Emacs
Hi there!
Please help me figure out what's stopping the compiler to complete its task!
1.#include <iostream>
2.using namespace std;
3.
4.int main()
5.{
6. cout << "hello world" << endl;
7. return 0;
9.}
I used Emacs makefile: gcc –o hello –g hello.cpp
After compiling! Please see below error message
cd /c++/hello/
gcc -o hello -g hello.cpp
