How to Check GCC Version on a Linux Server ?

There are several reasons why you might need to check the GCC version installed on your Linux system:

  1. Compatibility: Some software packages, libraries, or frameworks require a specific version of GCC to compile or run correctly. By checking the GCC version, you can ensure that your system meets the requirements for building or running the desired software.
  2. Troubleshooting: When facing issues while compiling or building software, checking the GCC version can help you identify whether the problem is related to the compiler version. In some cases, upgrading or downgrading the GCC version might resolve the issue.
  3. Performance improvements: Newer versions of GCC often include optimizations, bug fixes, and performance enhancements. By checking your current GCC version, you can determine if it’s worth upgrading to a more recent version to benefit from these improvements.
  4. Security: Staying up-to-date with the latest GCC version is essential for maintaining the security of your system. Newer versions may contain security patches and fixes for known vulnerabilities. Checking the GCC version helps ensure you are using a secure version of the compiler.
  5. Language features: GCC supports multiple programming languages such as C, C++, Objective-C, Fortran, Ada, D, and others. Newer GCC versions often introduce support for new language features and standards. By checking the GCC version, you can verify if your compiler supports specific language features or standards required for your project.
  6. Collaboration: When working in a team, it’s essential to have a consistent development environment across all team members. Checking the GCC version ensures that all team members are using the same compiler version, which helps avoid issues related to different compiler behaviors or features.
