0x09. C - Static libraries

Resources

Read or watch:

Learning Objectives

General

  • What is a static library, how does it work, how to create one, and how to use it
  • Basic usage of ar, ranlib, nm

Tasks

0. A library is not a luxury but one of the necessities of life

Create the static library libholberton.a containing all the functions listed below:

int _putchar(char c);
int _islower(int c);
int _isalpha(int c);
int _abs(int n);
int _isupper(int c);
int _isdigit(int c);
int _strlen(char *s);
void _puts(char *s);
char *_strcpy(char *dest, char *src);
int _atoi(char *s);
char *_strcat(char *dest, char *src);
char *_strncat(char *dest, char *src, int n);
char *_strncpy(char *dest, char *src, int n);
int _strcmp(char *s1, char *s2);
char *_memset(char *s, char b, unsigned int n);
char *_memcpy(char *dest, char *src, unsigned int n);
char *_strchr(char *s, char c);
unsigned int _strspn(char *s, char *accept);
char *_strpbrk(char *s, char *accept);
char *_strstr(char *haystack, char *needle);

Mode: mandatory


File: libmy.a, main.h

1. Without libraries what have we? We have no past and no future

  • Create a script called create_static_lib.sh that creates a static library called liball.a from all the .c files that are in the current directory.

Mode: mandatory

File: create_static_lib.sh
