                      4: changes that might cause problems in the build process, and a guide for
                      5: what to do if something doesn't work.

1.123     jmc         7: For a more detailed description of the recommended way to build NetBSD
                      8: using build.sh, see the BUILDING file.

                     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.

        !            20:         The threading model was changed when the newlock2 branch
        !            21:         was merged to NetBSD-current.  If you boot with a new
        !            22:         kernel (version 4.99.10), then you also need a new pthread
        !            23:         library (/usr/lib/libpthread.so.0.7).  If you boot with
        !            24:         an old kernel, then you need the old pthread library
        !            25:         (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
        !            26:         the pthread library in sync, old threaded applications should
        !            27:         continue to work with an old or new kernel.  Note that named(8)
        !            28:        is the only threaded application in the base system.

                     43:        changed to indicate that our libc has ssp support built-in and
                     44:        does not depend on -lssp and -lssp-nonshared. You'll need to

                     59:        if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed

                     72:        (like Grub). If you use a linker (ld) older than from 2006/04/17, it
1.147     christos   73:        will be unable to link the kernel because of a bug and ld will fail
                     74:        with an error like:

                     77:        You need to update at least src/gnu/dist/binutils/ld and recompile
                     78:        and install the linker. If using the build.sh script, the easiest
                     79:        way is with a "build.sh tools" command, with any other options
                     80:        that you use normally. When using build.sh, the linker binary is
                     81:        installed as ${TOOLDIR}/bin/i386--netbsdelf-ld.

                     86:        you need to update ofwboot. After a full build, just copy
                     87:        /usr/mdec/ofwboot to /, or do a rebuild of
