CentOS Fortran开发工具推荐

1. GNU Fortran (gfortran)
gfortran is the most widely used open-source Fortran compiler in the Linux ecosystem, fully integrated with the GNU Compiler Collection (GCC). It supports Fortran 95 and later standards (including Fortran 2003/2008/2018), making it suitable for both legacy code maintenance and modern development. gfortran is highly optimized for general-purpose computing and works seamlessly with CentOS’ native package manager. Installation is straightforward: sudo yum install gcc-gfortran, and verification can be done with gfortran --version. For large projects, combining gfortran with make (install via sudo yum install make) enables efficient build automation.

2. Intel Fortran Compiler (ifort)
Intel Fortran Compiler is a proprietary, high-performance compiler optimized for Intel processors. It delivers superior performance for numerical and scientific computing tasks (e.g., HPC, simulations) by leveraging Intel’s architecture-specific optimizations. ifort supports the latest Fortran standards (Fortran 2018+) and integrates with Intel oneAPI tools. On CentOS, you can install ifort via Intel’s oneAPI base toolkit (download from Intel’s website), then configure environment variables by adding source /opt/intel/oneapi/setvars.sh to your ~/.bashrc. This compiler is ideal for users needing maximum performance on Intel hardware.

3. Code::Blocks
Code::Blocks is a free, open-source IDE that supports Fortran development through plugins. It offers essential features like syntax highlighting, code folding, smart indentation, and project management, making it beginner-friendly. To install on CentOS, run sudo yum groupinstall "Development Tools" followed by sudo yum install codeblocks. While it lacks advanced debugging tools out of the box, its lightweight design and extensibility (via plugins) make it a good choice for small to medium-sized projects.

4. Visual Studio Code (VS Code)
VS Code is a lightweight but powerful cross-platform editor that supports Fortran via extensions. Key extensions include Modern Fortran (for syntax highlighting and IntelliSense), fortran-language-server (for code navigation and diagnostics), and C/C++ (for debugging). Installation involves downloading VS Code from its official website, then adding these extensions via the Extensions Marketplace. VS Code is highly customizable and integrates with version control systems (e.g., Git), making it a flexible choice for developers who work across multiple languages.

5. Eclipse CDT (C/C++ Development Tooling)
Eclipse CDT is an open-source IDE primarily for C/C++, but it can be extended to support Fortran via plugins like Photran (a Fortran development plugin for Eclipse). It provides advanced features such as project management, code refactoring, and debugging. To install, download Eclipse from its official site, then add the CDT and Photran plugins via the Eclipse Marketplace. While setup is more complex than other tools, Eclipse CDT is suitable for large-scale, team-based Fortran projects.

6. Open Watcom Fortran Compiler (WFortran)
Open Watcom is a free, open-source compiler suite that includes a Fortran 77/90 compiler (WFortran). It is designed for compatibility with legacy systems and supports older Fortran standards (Fortran 77/90). Installation on CentOS may require downloading binaries from third-party repositories or building from source. WFortran is a good option for maintaining legacy Fortran 77 code, but it lacks support for newer Fortran standards.

7. NAG Fortran Compiler (NAGFortran)
NAG Fortran Compiler is a commercial compiler known for its strict adherence to Fortran standards (Fortran 95/2003/2008/2018) and high-quality code optimization. It is often used in academic and industrial environments where standard compliance is critical. NAGFortran is available for CentOS via NAG’s official website, and installation requires a license. While it is not free, its robustness and compliance make it a top choice for mission-critical applications.

8. Flang (LLVM Fortran Compiler)
Flang is an emerging Fortran compiler developed as part of the LLVM project. It supports modern Fortran standards (Fortran 2008+) and integrates with LLVM’s optimization and code generation framework. Flang is still in active development, so it may lack some advanced features of mature compilers. However, it is a good choice for developers interested in experimenting with the latest Fortran features or integrating with LLVM-based tools. Installation on CentOS may require building from source or using pre-built binaries from LLVM’s repository.
