If you are a programmer working on the Windows platform and using GCC as your compiler, you may need to link object files and libraries to build your final executable. Here's a step-by-step guide on how to do this.

Step 1: Compile your source files

First, compile your source files using GCC. For example, if you have a source file named 'main.c', you can compile it using the following command:

gcc -c main.c

This will generate 'main.o', the object file for your source code.

Step 2: Compile external libraries

If you are using external libraries in your project, you need to compile them as well. For example, if you have a library named 'libmath', you can compile it using the following command:

gcc -c libmath.c

This will generate 'libmath.o', the object file for the library.

Step 3: Link object files

Once you have all the necessary object files, you can link them together to build your final executable. Use the following command to link the object files:

gcc -o myprogram main.o libmath.o

This will create an executable file named 'myprogram' using the object files 'main.o' and 'libmath.o'.

Step 4: Link external libraries

If your project depends on external libraries, you need to link them as well. Use the following command to link the external library:

gcc -o myprogram main.o libmath.o -lm

The '-lm' flag tells GCC to link the math library to your program.

Step 5: Run your program

Finally, you can run your program by simply typing its name in the command prompt:

myprogram

This will execute your program and produce the expected output.

By following these steps, you can effectively use GCC to link object files and libraries on the Windows platform. This process allows you to compile and build complex programs with dependencies, enabling you to create powerful software solutions for your projects.
