PART I - CREATING TARBALL SOFTWARE PACKAGES


1.1- How to build a tarball software package from a program made of a single source code

Step 1) Source code development


We are going to develop a software that shows us our login name at system. Make a new directory called loginteller on your system. Change to the newly created directory. Start an instance of Geany and write the folliwing source code in C language:

/* loginteller.c
 * Based on monousuar.c at http://www.binefa.net/gnu/gcc/processos/Informacio_d_usuari.html
 * www.binefa.cat
 * 20120507
*/
#include <stdio.h>
#include <unistd.h>    // getlogin()
#include <stdlib.h>    // exit()

int main(){
    char *szLogin;
   
    if((szLogin = getlogin())==NULL){
        perror("getlogin");
        exit(EXIT_FAILURE);
    }  
    printf("Your login name at the system is : %s\n",szLogin);

    return (0);
}

In order to check if your code works properly, run the following commnads:

dacomo@inf1-dacomo:~/loginteller$ gcc  loginteller.c  -o  loginteller
dacomo@inf1-dacomo:~/loginteller$ ./loginteller

Your terminal will show you the following message:

Your login name at the system is: dacomo

Of course, the message displayed by the terminal depends on what your username is in the system.

Step 2) Creating a Makefile archive

A Makefile typically starts with some variable definitions which are then followed by a set of target entries for building specific targets (typically .o & executable files in C) or executing a set of command associated with a target label. We are going to develop a Makefile for easily:
a) Compiling and linking the source code
b) Cleaning binary files
c) Installing binary files on your system
d) Uninstalling binary files on your system

Start an instance of Geany and write the following Makefile:

############################################################################
# Makefile for building: loginteller
# 20120508 - www.binefa.cat
#############################################################################
####### Compiler, tools and options

CC              = gcc
CFLAGS          = -o
INSTALL_PROGRAM = install -m 755 -p
DEL_FILE        = rm -f
####### Files
SOURCES   = loginteller.c
DESTDIR   = /usr/local/bin
TARGET    = loginteller
####### Compilation and cleaning. Be careful, you have to write a TAB character at the beginnig of each command. Do not write whitespace characters.
loginteller:
    $(CC) $(SOURCES) $(CFLAGS) $(TARGET)
clean:
    $(DEL_FILE) $(TARGET)
####### Install and uninstall. Be careful, you have to write a TAB character at the beginnig of each command. Do not write whitespace characters.
install: $(TARGET)
    $(INSTALL_PROGRAM) $(TARGET) $(DESTDIR)
uninstall:
    $(DEL_FILE) $(DESTDIR)/$(TARGET)

 Now, you can easily:
a) Compile loginteller.c running the following command: make (or make loginteller)
b) Clean  old binaries and object files  running the following command: make clean
c) Install a binary on your system running as a sudo user the following command: make install
d) Uninstall a binary on your system running as a sudo user the following the command: make uninstall


Step3) Creating a README file

A README file is a text file that contains information for the user about the program. README files often contain instructions and additional help. Add a README file with the following content:

********************************************
*                                          *
* loginteller v1.01                        *
* Copyright (C) 2010-2021, jobima & dacomo *
*                                          *
********************************************

Welcome to the loginteller program!  This program, once installed as
/usr/local/sbin/loginteller,  tells current login name at the system.

Step 4) Creating a .tar.gz file

Run the following command:

dacomo@inf1-dacomo:~/loginteller$ tar cfz loginteller-1.01.tar.gz loginteller.c Makefile README



1.2- How to build a tarball software package from a program made of  multiple source code

Step 1) Source code development
We are going to develop a software that shows us our login name and UID at system. Make a new project directory called loginteller2 on your system. Change to the newly created directory. Start an instance of Geany and write the following source codes in C language:

// login.c
// login.c gets the user's login username
// jobima & dacomo
// 20230509

#include <stdio.h>
#include <unistd.h> // getlogin()
#include <stdlib.h> // exit()

void showLogin(){
    char *szLogin;

    if((szLogin = getlogin())==NULL){
        perror("getlogin");
        exit(EXIT_FAILURE);
    }
    printf("Your login name at the system is : %s\n",szLogin);
}

----------------------------------------------------------------------
// Program name: uid.c
// uid.c gets the user's UID number
// Authors: jobima & dacomo
// Date: 20230509

#include <stdio.h>
#include <unistd.h> // getuid()

void showUID(){
    int iUID;

    iUID = getuid();
    printf("Your UID number at the system is : %i\n",iUID);
}

----------------------------------------------------------------------

// Header name: loginteller2.h
// Header required for loginteller2.c
// Authors: jobima & dacomo
// Date: 20230509

#ifndef LOGINTELLER2_H
#define LOGINTELLER2_H
void showLogin();
void showUID();
#endif

------------------------------------------------------------------------

// Program name: loginteller2.c
// Authors: jobima & dacomo
// loginteller shows the user's login name and UID number
// Date: 20230509

#include "loginteller2.h"

int main(){
    showLogin();
    showUID();

    return 0;
}

Step 2) Creating a Makefile archive

Start an instance of Geany and write the following Makefile:

############################################################################
# Makefile for building: loginteller2
# jobima and dacomo
# 20230509
############################################################################
#
####### Compiler
CC              = gcc
####### Compiler options
CFLAGS          = -Wall -c
LFLAGS          = -Wall -o
####### Installing and uninstalling programs and options
INSTALL_PROGRAM = install -p -m 755
DEL_PROGRAM     = rm -f
####### Files and directories
SOURCES   = loginteller2.c login.c uid.c
DEPS      = loginteller2.h
OBJECTS   = loginteller2.o login.o uid.o
DESTDIR   = /usr/bin
TARGET    = loginteller2
####### Compilation, linking and installing. Be careful, you have to write a TAB character at the beginnig of each command. Do not write whitespace characters.
%.o: %.c $(DEPS) $(SOURCES)
        $(CC) $(CFLAGS) $(SOURCES)
loginteller2:$(OBJECTS)
        $(CC) $(OBJECTS) $(LFLAGS) $(TARGET)
install:$(TARGET)
        $(INSTALL_PROGRAM) $(TARGET) $(DESTDIR)
####### Uninstalling and cleaning. Be careful, you have to write a TAB character at the beginnig of each command. Do not write whitespace characters.clean:
clean:$(TARGET) $(OBJECTS)
        $(DEL_PROGRAM) $(TARGET) $(OBJECTS)
uninstall:
        $(DEL_PROGRAM) $(DESTDIR)/$(TARGET)

Now, you can easily:
a) Compile and link your source codes running the following command: make loginteller2
c) Install a binary on your system running as a sudo user the following command: sudo make install
b) Clean  old binaries files  running the following command: make clean
d) Uninstall a binary on your system running as a sudo user the following the command: sudo make uninstall


Step3) Creating a README file

A README file is a text file that contains information for the user about the program. README files often contain instructions and additional help. Add a README file with the following content:

PART II - CREATING .DEB PACKAGES


2.1- Installing checkinstall

In order to build a .deb package you need an application called checkintall installed on your system. In ordre to install checkintall run the following commands:

dacomo@inf1-dacomo:~$ sudo aptitude update
dacomo@inf1-dacomo:~$ sudo aptitude install checkinstall

But If  If your system tells you that it couldn't find a package called checkinstall then add the following line to /etc/apt/sources.list:

deb http://deb.debian.org/debian buster-backports main

and run again:

dacomo@inf1-dacomo:~$ sudo aptitude update
dacomo@inf1-dacomo:~$ sudo aptitude install checkinstall


2.2- How to build a .deb software package from a program made of a single source code

We are going to create a .deb software package for the programa called loginteller.c that we developed in section 1.1 following these steps:

a) Check if Makefile exists. If it does not exist then you have to create it. Remember: Makefile and loginteller.c have to be stored in the same directory.

b) If you had installed a previous version of loginteller from a tarball package then,  remove any  binary running make clean and uninstall the software running make uninstall.

c) Run checkinstall:

dacomo@inf1-dacomo:~/loginteller$ checkinstall --install=no --deldesc=yes --backup=no

checkinstall 1.6.3, Copyright 2010 Felipe Eduardo Sanchez Diaz Duran
           This software is released under the GNU GPL.


The package documentation directory ./doc-pak does not exist.
Should I create a default set of package docs?  [y]: n

Please write a description for the package.
End your description with an empty line or EOF.
>> It tells current login name at the system
