DISCUSSION: Building C++ programs on Linux

The book is outdated. Throw it out.

in vi editor:

for c:
in shell :
step 1:type vi <your_program_name>.c
step 2: type gcc <your_program_name>.c -o <your_program_name>.out
or
type gcc <your_program_name>.c -o a.out
step 3:type ./<your_program_name>.out
or
./a.out

for c++:
in shell :
step 1:type vi <your_program_name>.cpp
step 2: type g++ <your_program_name>.cpp -o <your_program_name>.out
or
type g++ <your_program_name>.cpp -o a.out
step 3:type ./<your_program_name>.out
or
./a.out

USING EMACS EDITOR: 1.type emacs<file name> on terminal. 3. then type " i" ( i= insert) 4. then write source code . for details www.howstuffworks.com how to works "C" programming? 5. then press esc : wq it is save now. 6. now for comile the programme type, cc <filename> 7. then for execute type (dot)/a.out ( dot = . ) 8. then it will see your screen. USING KWRITE IN ( GNOME OR KDE DESKTOP) 1. Open terminal & type kwrite 2. then write source code 3. then click file . 4. then clck save as 5. save the file wtth extension .c/.cpp now for comile the programme type, cc <filename> 7. then for execute type (dot)/a.out ( dot = . ) I hope it will helpful .

I know this is old... But the EMACS help is strange... It describes VI syntax NOT emacs !!

I have a C++ program called estsert.cpp, that estimates the parameters of an AR(p), MA(q) or ARMA(p,q) time series.

The command

g++ estsert.cpp -o estsert

makes the LINUX executable program estsert, and the execution is as we know,


./estsert

If I want to make the executable file on Windows, I need to create using Visual C++ a
new project with the same name (estsert.dsw), and the code

#include <stdio.h>
#include "sertimp.h"

is copied from the LINUX file copied on memory stick after

// estsert.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

After this I make it executable, and I can run the program on computers that has only Windows as operating system.

My question is if I can make an Windows executable program from a C++ program on LINUX, without accesing a computer with Windows.

Sincerely,
Daniel Ciuiu
