1.123     jmc         3: This file (UPDATING) is intended to be a brief reference to recent
                      4: changes that might cause problems in the build process, and a guide for
                      5: what to do if something doesn't work.
1.1       abs         6:
1.123     jmc         7: For a more detailed description of the recommended way to build NetBSD
                      8: using build.sh, see the BUILDING file.
                      9:
                     10: Note that much of the advice in this UPDATING file was written before
                     11: build.sh existed.  Nevertheless, the advice here may be useful for
                     12: working around specific problems with build.sh.

                     23:        For a while, unprivileged UPDATE builds would fail to
                     24:        succeed at the checkflist stage, complaining that
                     25:        ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
                     26:        problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
                     27:        If you already hit this problem, update the .mk file,
                     28:        remove ${DESTDIR}/stand/<arch>, and re-run the build.

                     32:        stub, to a c file that calls an assembly stub. You need to
                     33:        'rm -f posix_fadvise.* .depend' in the libc build directory to
                     34:        avoid using the old assembly stub.

                     38:        get ACPI errors before the attachment, please update your kernel

                     44:        anymore. The itesio(4) driver now uses the Super I/O address port

                     50:        You need to update any custom kernel configuration file you have
                     51:        to remove any references to pccons (which includes removing the
                     52:        now useless XSERVER option) and replace them with the correct
                     53:        entries for the wscons driver.  See the GENERIC configuration file

                     58:        enumerate interfaces was fixed.  The bug began to cause
                     59:        problems after 20070911 when the kernel's SIOCGIFCONF
                     60:        implementation was repaired.  From 20070529 to 20070911 racoon
                     61:        could not enumerate interfaces.  (These are noted because
                     62:        normal kernel/userspace version matching hygiene is not
                     63:        sufficient to avoid this problem.)  Ensure that both kernel
                     64:        and userland are from after 20070913.

                     68:        the logic to pass down STRIP from mk been removed.  This forces
                     69:        a re-installation of tools.

                     73:        has been changed.  Rather than modify the pathname (and copy back
                     74:        to userspace) namei() and lookup() directly check the emulation
                     75:        root. One side effect is that absolute symlinks inside the emulated
