Programming From The Ground Up

This book teaches programming using Linux Assembly Language.

The Exercises are written in 32-bit x86 assembler. This is kind of obsolete but does the purpose of teaching how the machine works.

Table of Exercises

Program	Purpose
chap3ex1	exit system call
chap3ex2	find max value
chap4ex1	function for power
chap4ex2	recursive factorial function
chap5ex1	toUpper function with file args
chap06	reading and writing records
chap07	records with error handling for add-year
chap08/hello	hello world linking libc.so
chap08/librecord	creating a dynamic library
chap09/memory-1.0	memory manager like malloc
chap09/memory-64-bit	64-bit malloc and free
chap09/records	read-records using memory manager
chap10	converting numbers to strings

Install 32 bit version libc

$ apt-get install libc6:i386 libc6-dev-i386

Assemble the source to an object file

$ as --32 chap3ex1.s -o exit.o

Link the object file to an executable

$ ld -m elf_i386 exit.o -o exit

Do all and run

$ as --32 chap3ex1.s -o object.o && ld -m elf_i386 object.o -o prog && ./prog
