How Do I Compile C 11 Code with g Using Compiler Flags?

Compiling C 11 with g Using Flags

To update your C compiler to C 11, you need to specify appropriate flags. Flags are command-line arguments passed to the compiler that affect the compilation process.

Understanding Flags

When you specify a flag, it instructs the compiler how to interpret and process the source code. Flags can control various aspects of compilation, such as language version, optimization settings, and library inclusion.

Compiling with C 11 Support

To compile your C code with C 11 support, you need to use the following flags:

• -std=c 11: This flag tells the compiler to adhere to the C 11 language standard.
• -std=c 0x: This flag is a deprecated alias for -std=c 11. It was used in earlier versions of C .

If you are encountering the error message indicating lack of compiler support for C 11 features, you can resolve it by specifying either of these flags in the compilation command.

Example:

To compile your source file your_file.cpp with C 11 support, use the following command:

$ g++ -std=c++11 your_file.cpp -o your_program

Note:

If -std=c 11 does not work, you can try using -std=c 0x. The latter flag is deprecated but may still be supported in some environments.
