2.2.7. Example: Building a C program with the GCC (compiling and linking in one step)

Procedure

1. Create a directory hello-c:

   $ mkdir hello-c

2. Change to the created directory:

   $ cd hello-c

3. Create file hello.c with the following contents:

   #include <stdio.h>
   
   int main() {
     printf("Hello, World!\n");
     return 0;
   }

4. Compile and link the code with GCC:

   $ gcc hello.c -o helloworld

   This compiles the code, creates the object file hello.o, and links the executable file helloworld from the object file.

5. Run the resulting executable file:

   $ ./helloworld

   Hello, World!
