Question

 This is a program for a simple library system.  My question is how do you get this to work on a linux machine?  Conio doesn't work and i'm pretty sure process.h doesn't either.  I've heard about the curses library but I have no idea on how to do that.   #include<fstream.h> #include<conio.h> #include<stdio.h> #include<process.h> #include<string.h> #include<iomanip.h>

Explanation / Answer

I assume you are trying to compile on Linux. <process.h> is a windows only header and I believe <conio.h> is as well. There may be Linux equivilants if you could post what functions you are trying to use. I usually use the following for cross compatability over windows and linux.

Code:

It helps with somestandard ANSI functions that are defined in different headers on Linux than they are on Windows.

Use any one of the following syntax to compile the program called demo.c:

How do I compile a C++ program that uses Xlib graphics functions?

The syntax is as follows when need pass the -lX11 option with gcc to link with the Xlib libraries:
g++ fireworks.C -o executable -lX11

  cc program-source-code.c -o executable-file-name  

OR

  gcc program-source-code.c -o executable-file-name  

OR

  ## assuming that executable-file-name.c exists ##  make executable-file-name
