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 13: <cstdint> (for std::int8_t, std::int32_t etc.) // This case So, likely with GCC 12 and older cstdint has been included as implementation detail by one of the libstdc++ headers VTK includes but isn't included anymore.
