Porting to GCC 14

+ +

+The GCC 14 release series differs from previous GCC releases in +a number of ways. Some of these are a result +of bug fixing, and some old behaviors have been intentionally changed +to support new standards, or relaxed in standards-conforming ways to +facilitate compilation or run-time performance. +

+ +

+Some of these changes are user visible and can cause grief when +porting to GCC 14. This document is an effort to identify common issues +and provide solutions. Let us know if you have suggestions for improvements! +

C++ language issues

Header dependency changes

Some C++ Standard Library headers have been changed to no longer include +other headers that were being used internally by the library. +As such, C++ programs that used standard library components without +including the right headers will no longer compile. +

+The following headers are used less widely in libstdc++ and may need to +be included explicitly when compiling with GCC 14: +

<algorithm> + (for std::copy_n, std::lower_bound, + std::remove, std::reverse, + std::sort etc.) +
