A Toolchain is the set of Programming Tools that are used to create software. The Tools are used in a chain , so that the output of each tool becomes the input for the next tool.<\/p>\n

 <\/p>\n

Editor:<\/b><\/p>\n

Editor is program in which we can write our code and edit that code. Gedit , kwrite are the examples of editors.<\/p>\n

 <\/p>\n

File name : Demo.c<\/b><\/p>\n

#include<stdio.h><\/p>\n

#define MAX 10<\/p>\n

int Add(int No1, int No2)<\/p>\n

{<\/p>\n

Int Ans; \/\/Local Variable<\/p>\n

Ans = No1 + No2 + MAX ;<\/p>\n

printf(\u201cAddition of Two Numbers is %d\u201d,Ans);<\/p>\n

return Ans;<\/p>\n

}<\/p>\n

 <\/p>\n

Pre-processor:<\/b><\/p>\n

The Pre-processors provide the ability for the inclusion of header files, macro expantion, conditional compilation,and line control.<\/p>\n

Pre-processor takes lines beginning with ‘#’ as a directives. Because it does not know about the underlying language.<\/p>\n

After Preprocessing it will give the expanded code as a output having extension .i.<\/p>\n

 <\/p>\n

File name : Demo.i<\/b><\/p>\n

int printf( const char * format, …);<\/p>\n

int scanf( const char * format, …);<\/p>\n

int Add(int No1, int No2)<\/p>\n

{<\/p>\n

int Ans;<\/p>\n

Ans = No1 + No2 + 10 ;<\/p>\n

printf(\u201cAddition of Two Numbers is %d\u201d,Ans);<\/p>\n

return Ans;<\/p>\n

}<\/p>\n

Compiler :<\/b><\/p>\n

Compiler is the program which is used for translating source code from a high level programming language (like c,c++) to lower level programming language (like machine language).So, in this case we consider that output is in assembly language having extention .asm or .s.File name : Demo.asm<\/b>Add: PUSH ECX PUSH EDX ADD ECX,EDX ADD ECX,10 MOV EAX,ECXRETN<\/p>\n

 <\/p>\n

Assembler :<\/b><\/p>\n

Assembler is a program which translates assembly language program to an object file , which<\/p>\n

contains the code in machine language. Object file does contain the machine code but still it is non-executable.<\/p>\n

 <\/p>\n

Extention of object file is .obj.<\/p>\n

 <\/p>\n

File name : Demo.obj<\/b><\/p>\n

Linker :<\/b><\/p>\n

A Linker is a program which takes one or more object files and combines them into a single<\/p>\n

executable program having extension .exe.<\/p>\n

 <\/p>\n

File name : Demo.exe<\/b><\/p>\n

\u00a0<\/b><\/p>\n

Loader :<\/b><\/p>\n

A Loader is a program which is the part of OS i.e. operating system that is responsible for loading programs.<\/p>\n

It places program in memory (RAM) and prepares them for the execution and loading a program<\/p>\n

involves reading a contents of an executable file like text , data into the memory.<\/p>\n

 <\/p>\n

Demo.exe running in RAM<\/p>\n

Set of the Commands which will elaborate the Toolchain components :-<\/b><\/p>\n

Step 1. <\/b>Create a file name as Demo.c which contains simple C program.<\/p>\n

\u00a0<\/b><\/p>\n

Step 2. <\/b>Compile that file using command<\/p>\n

# gcc -S -o Demo.S Demo.c<\/b><\/p>\n

This command gives output file in assembly language named as Demo.S<\/p>\n

\u00a0<\/b><\/p>\n

Step 3. <\/b>Pass that Assembly file to assembler which gives output as a object file named as<\/p>\n

Demo.o<\/p>\n

# as -o Demo.o Demo.S<\/b><\/p>\n

\u00a0<\/b><\/p>\n

Step 4. <\/b>Pass that object file to Linker which gives output as a executable file.<\/p>\n

# ld -o Demo -lc -dynamic-linker \/lib\/ld-linux.so.2 Demo.o -e main<\/b><\/p>\n

\u00a0<\/b><\/p>\n

Step 5. <\/b>Run that executable using<\/p>\n
