GCC (GNU Compiler Collection) is a widely-used, open-source compiler system that supports multiple programming languages, including C, C++, Fortran, Ada, Go, and Objective-C. Developed by the GNU Project, GCC is the standard compiler for Linux systems, including Debian 12, and is essential for building and compiling software across various domains.

Key Features of GCC on Debian 12

1. Multi-Language Support
   • GCC includes compilers for C (gcc), C++ (g++), Fortran (gfortran), Ada (gnat), Go (gccgo), and Objective-C (gobjc).
2. Cross-Platform Compilation
   • Supports cross-compilation, allowing developers to build code for different architectures, including x86, ARM, and RISC-V.
3. Optimization Levels for Performance
   • Offers multiple optimization levels from -O0 (no optimization) to -O3 (maximum optimization), improving execution speed and efficiency.
4. Standards Compliance
   • Fully supports modern programming standards such as C11, C++20, and Fortran 2018, ensuring compatibility and performance.
5. Debugging and Profiling Tools
   • Generates debugging information for tools like GDB (GNU Debugger) and supports performance profiling with tools like gprof.
6. Built-in Diagnostics and Warnings
   • Provides comprehensive warnings and error messages with flags like -Wall, -Wextra, and -pedantic, helping developers write cleaner and safer code.
7. Parallel and Distributed Compilation
   • Supports multi-threaded compilation using make -jN, significantly reducing build times for large projects.
8. Linking and Assembly Integration
   • Integrates with the GNU linker (ld) and assembler (as) for efficient compilation and linking of object files.

Step 1: Set Up a Server Instance

To begin, you need a Debian 12 server instance. Follow these steps to create one:

Access Shape.Host Dashboard: Log into your Shape.Host account and navigate to the Dashboard.

Click “Create”: Locate and click the “Create” button in the top-right corner of your dashboard.

Select Server Type: Choose “Instances” to configure your server environment.

Choose a Data Center Location: Select a data center closest to your target audience for optimal performance.

Pick a Hosting Plan: Choose a plan that suits your project, such as Standard or CPU-Optimized.

Set Up the Operating System: Select Debian 12 as your OS.

Finalize Configuration: Choose your preferred authentication method (SSH keys or password) and click Create Instance to deploy the server.

Find your instance’s IP address under the Resources section and use it to access your server.

---

Step 2: Connect to Your Instance

Connect to your server using SSH:

• Linux/macOS: ssh root@<your_server_ip>
• Windows: Use PuTTY. Enter your server’s IP address, select SSH, and log in using your credentials.
