Dear All,

I installed the eclipse cpp Oxygen.
I followed the instruction of a Lynda.com training how to run and debug a program.

< Please be aware that according to this: we should install the eclipse, the Java environment and something from the www.equation.com, it is called GCC(not existing anymore) Instead of this I installed MiniGW>

I chose a simple program to test it.
(1) I created a Project *New Project>>C/C++ Project (NEXT) C++ Managed Build (NEXT) Project name: Training
Toolchains Cross GCC (But here I can also choose MiniGW GCC) (FINISH)*
(2) I choose now a basic script, this one:
---------------------------
#include <iostream>
using namespace std;

int main()
{
cout << "Hello, World!";
return 0;
}
-----------------------------

(3) Then I click 'Run' and it is showing this error message:
"Launch failed. Binarz not found."
index.php/fa/32006/0/

1. I tried to find the solution with several way.
'Run Configurations..'
I tried to name a file and then choose it from here.
I tried it several way.

Please help me in that because it is important for me. Thank you in advance!
Andor

You can only run executables.
You have to compile the source then link the resultant object files along with system libraries to produce an executable.
This is called "Building".
To build either
1) use the hammer icon in the upper left of the toolbar
after using the down arrow next to it to select the configuration

or 2) select Project --> Build Project from the menu
you define which configuration to build with menu Project --> Build Configurations --> Set Active

The "Debug" configuration will add debugging information during the compile that is needed by the debugger.

Note that Eclipse only creates a makefile which is used by Make to build the executable.
You should read some tutorials on using Make and GCC.
For example, https://www3.ntu.edu.sg/home/ehchua/programming/cpp/gcc_make.html
If you don't know how to build executables without Eclipse then what Eclipse does will likely remain a mystery to you.
