Linker

Basic Introduction to the Linker

Begin Segment1
   Begin Procedure A
      Code For Procedure A
   End Procedure A
  End Segment

How the Linker Interacts with Other Computer Programming Components

• The compiler transforms source code into object code.
• The linker then takes this object code and combines it into an executable code.
• Finally, the loader loads this executable into memory for the computer to run.

Discussing the Linker's Role in Software Development

• Resolving Symbol References: Linker resolves external symbols from other object files or libraries.
• Combining Segments: It gathers similar segments into one for simplicity and optimal program functionality.
• Establishing the Program's Starting Address: It sets the entry point for the program, informing the operating system where to start executing the program.

 
Object File 1                           Object File 2
  
public:                                 public:  
   X(g)                                     Y(h)   
private:                               private: 
  int g                                  int h

Executable File
  
public: 
  X(g)
  Y(h)
private:
  int g
  int h

Delving into the Operation of a Linker

Understanding the Linker Working Mechanism

Detailed Explanation of Linker Technique in Programming

• Resolving references between the object files.
• Combining alike data sections into one.
• Resolving standard library calls.
• Calculating addresses and updating code with absolute addresses.

Exploring Practical Linker Examples

// functions.cpp
int add(int a, int b) {
    return a + b;
}

// main.cpp
#include

int add(int a, int b); // Forward declaration

int main() {
    std::cout << add(10, 5) <<  '\n';
    return 0;
}

Breakdown of the Linker Process in Software Development

Source File 1                  Source File 2

int sharedVariable; 	    void function() {
    sharedVariable = 5;	    printf("%d", sharedVariable);
}

Executable File

int sharedVariable;
void function() {
    sharedVariable = 5;
    printf("%d", sharedVariable);
}

Real-World Linker Examples in Computer Programming

// Functions.c
int add(int x, int y) {
  return x + y;
}

// Main.c
#include 
extern int add(int x, int y);
  
int main() {
  printf("Sum is: %d", add(10, 20));
  return 0;
}
