  • GCC 14 Build Failure

    Has anyone seen this on 16-CURRENT?

    I suspect, though haven't fully followed the trail, that gmp.h (from math/gmp) is
    not included by some header file. Or possibly not detected properly during ./configure.

    See https://bugs.freebsd.org/297562, this is a problem after base
    cd0727ec709b, causing gmp to fail to detect the inclusion of stdio.h.
