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.

1.123     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.

                     40:         The threading model was changed when the newlock2 branch
                     41:         was merged to NetBSD-current.  If you boot with a new
                     42:         kernel (version 4.99.10), then you also need a new pthread
                     43:         library (/usr/lib/libpthread.so.0.7).  If you boot with
                     44:         an old kernel, then you need the old pthread library
                     45:         (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
                     46:         the pthread library in sync, old threaded applications should
                     47:         continue to work with an old or new kernel.  Note that named(8)
                     48:        is the only threaded application in the base system.

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

                     73:        withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC

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

                     97:        You need to update at least src/gnu/dist/binutils/ld and recompile
                     98:        and install the linker. If using the build.sh script, the easiest
                     99:        way is with a "build.sh tools" command, with any other options
                    100:        that you use normally. When using build.sh, the linker binary is
