To install g++ on Fedora, you can use the following steps:
- Open the terminal on your Fedora system.
- Update the package repository cache by running the command: sudo dnf update
- Install the g++ compiler by running the command: sudo dnf install gcc-c++
- Verify the installation by checking the g++ version: g++ --version
After following these steps, you should have successfully installed g++ on your Fedora system and can start compiling C++ programs.

How to compile a C++ program using g++ on Fedora?
To compile a C++ program using g++ on Fedora, follow these steps:
- Open a terminal window by pressing Ctrl+Alt+T.
- Navigate to the directory where your C++ program is located using the cd command. For example, if your program is located in the Documents folder, you can use the following command: cd ~/Documents
- Once you are in the correct directory, use the following command to compile your C++ program: g++ -o output_filename input_filename.cpp Replace "output_filename" with the desired name for the compiled executable and "input_filename.cpp" with the name of your C++ source code file.
- Press Enter to run the command and compile your C++ program. If there are no errors in your code, the compilation process should complete successfully.
- After the compilation is finished, you can run your compiled program by using the following command: ./output_filename Replace "output_filename" with the name you specified earlier for the compiled executable.
- If your program requires any input, you can provide it by typing the required input and pressing Enter.
That's it! You have successfully compiled and run a C++ program using g++ on Fedora.
How to install g++ compiler for Fedora 33?

That's it! You have successfully installed the g++ compiler on Fedora 33.
What is the difference between g++ and clang on Fedora?
g++ and clang are both compiler tools used for compiling C++ code on Fedora (and other systems). Here are some differences between the two:
- Compiler Steering: g++ is part of the GNU Compiler Collection (GCC), which is a suite of compilers developed by the GNU Project. clang is developed by LLVM Project and acts as a standalone C/C++ compiler, although it also supports other languages.
- Language Compatibility: g++ is known for its strict adherence to C++ standards and has been around for a longer time, providing solid support for older versions of C++. clang, on the other hand, is known for its fast and efficient compilation process and often provides better diagnostics for code errors.
- Toolchain Integration: g++ is tightly integrated with the GNU toolchain, which includes tools like glibc, binutils, and GNU make. clang has its own toolchain that includes Clang Static Analyzer, AddressSanitizer, and other tools for code analysis and optimization.
- Performance: clang is known for its fast compilation times and optimized code generation, making it a popular choice for large codebases and performance-critical applications. g++ is also performant but may not always match clang's level of optimization.
Ultimately, the choice between g++ and clang on Fedora (or any other system) comes down to personal preference, project requirements, and compatibility with existing codebases. Some developers may prefer one compiler over the other based on their familiarity with the tools, while others may choose based on specific features or performance considerations.
How to enable g++ in the terminal on Fedora?
To enable g++ on Fedora, you can install the gcc-c++ package. Here's how you can do it:
- Open the terminal on your Fedora system.
- Update the package list by running the following command:
1
|
sudo dnf update
|
- Install the gcc-c++ package by running the following command:
1
|
sudo dnf install gcc-c++
|
- After the installation is complete, you can use g++ in the terminal to compile C++ programs. You can test it by running the following command:
1
|
g++ --version
|
Now g++ should be enabled in the terminal on your Fedora system. You can start writing and compiling C++ programs using g++ as the compiler.
