Step 3 – Verify GCC Installation on Rocky Linux 8

At this point, you can verify your GCC installation on Rocky Linux 8 by checking its version:

gcc --version

Output
gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-15)
Copyright (C) 2018 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

To see the installation path of GCC, you can use the command below:

whereis gcc

Output
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz /usr/share/info/gcc.info.gz

Step 3 – Create a Sample project with GCC Compiler

At this point, you can test your GCC compiler by creating a sample project.

First, create a file called “hello.c” in your home directory with your favorite text editor, here we use the vi editor:

cd && sudo vi hello.c

Add the following content to the file:

#include <stdio.h>

int main() {
  printf("OrcaCore, Hello world!\n");
  return 0;
}

When you are done, save and close the file.

Next, compile the “hello.c” source code with the GCC compiler on Rocky Linux 8 by using the following command:

gcc hello.c -o helloworld

Then, run the executable hello word file:

./helloworld

In your output you should see:

Output
OrcaCore, Hello world!

Conclusion

At this point, you have learned to Install GCC Compiler on Rocky Linux 8 and create a test program with it. GCC is a great compiler tool that includes many programming languages that you can use to compile and build your programs.
