How Can I Check for C 11 Support During Compilation?

Determining C 11 Support at Compile-Time

C programmers often need to determine if their compiler supports specific features of C 11 to ensure compatibility with their code. Here's how to achieve this:

Utilizing the __cplusplus Constant

Some compilers provide a constant named __cplusplus, which indicates the supported C standard version. The following example checks for C 11 support:

#if __cplusplus <h3 id="Leveraging-Boost-Macros">Leveraging Boost Macros</h3><p>Another option is to use macros from the Boost library, which provides defines for specific C  11 features, such as:</p>

• BOOST_CXX11_VARIADIC_MACROS
• BOOST_CXX11_THREADS

#ifndef BOOST_CXX11_VARIADIC_MACROS

#error "Your compiler doesn't support variadic templates."

#else

template <typename... datatypelist>
class Tuple
{
    // ...
}

#endif</typename...>
