    C++23 Support in GCC

    + +

    GCC has experimental support for the next revision of the C++ + standard, which is expected to be published in 2023.

    + +

    C++23 features are available since GCC 11. To enable C++23 + support, add the command-line parameter -std=c++2b + to your g++ command line. Or, to enable GNU + extensions in addition to C++23 features, + add -std=gnu++2b.

    + +

    Important: Because the ISO C++23 standard is still + evolving, GCC's support is experimental. No attempt will + be made to maintain backward compatibility with implementations of C++23 + features that do not reflect the final standard.

    + +
