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.

        !            19:        Assembler files on amd64 and i386 no longer use -traditional-cpp.
        !            20:        This can break the build of individual parts of the tree.  This is
        !            21:        handled correctly by build.sh.  Manual builds have to update
        !            22:        /usr/share/mk and re-run config(1) for any kernel configurations as
        !            23:        needed.

1.217     jruoho     25: 20101217:
                     26:        The tcpdump(8) program was changed to drop privileges and chroot(2)
                     27:        by default. It may be necessary to manually update passwd(5) and
                     28:        group(5) in order to make the program work with existing setups.

                     31:        The latest changes to setenv(3) dissallow setting environment
                     32:        variables with names that contain '='. Revision 1.18 of env.c
                     33:        assumed that this was allowed. Installing a new libc with an
                     34:        old copy of /usr/bin/env causes env x=1 printenv | grep x= to
                     35:        break which affects the autoconf tests for dependency finding,
                     36:        so building gcc will end up printing:
                     37:            checking dependency style of gcc... none
                     38:            configure: error: no usable dependency style found
                     39:        Fix it by rebuilding and re-installing env.

                     49:        unless they are rebuilt.  If you are building with MKUPDATE=yes,
                     50:        you need to clean the src/external/bsd/atf/tests/ and the src/tests/

1.214     dholland   60:        include ctype_local.h, so you have to make cleandir in tools/mklocale.

                     69:        libXX.so.  All now stale regular .so files can be removed from

                     74:        but has not been marked obsolete so it is not removed
                     75:        from the system when upgrading.
                     76:        As such, you will need to remove them from your object
                     77:        and destination directories.

1.202     mrg        85: 20091001:
1.206     dholland   86:        On amd64 you must rebuild tools (to get the new binutils)
                     87:        before building a kernel, or the build fails on cpufunc.S.

                     95:        libc build changed so that strchr() provides the extra entry
                     96:        point for index(). Update build of libc.a (and libc_pic.a)
                     97:        may fail because the archive contains the unwanted index.o.

                    102:        without a clean objdir, at least for src/external/mit/xorg.

                    106:        src/external/mit/xorg.  Upgrading a system from sets will not
                    107:        work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
                    108:        subdirectory has been changed into a file, and this needs to
                    109:        be manually "rm -r"'ed before installing xbase.tgz.

                    112:        Several new functions were added to string.h/libc, and this
                    113:        can cause autoconf problems during the tool build for people
                    114:        who fail to clean out their tools objects properly. If you
                    115:        note messages about stpcpy, stpncpy or strnlen accompanying a
                    116:        failure during the tool build, clean out all your tools
                    117:        objects and start again.

                    120:        The i386 port was switched to i486 default toolchain.  This requires
                    121:        cleaning your src/tools directory and $TOOLDIR and rebuilding them.
                    122:
1.192     skrll     123: 20090126:
1.207     mbalmer   124:        The __posix_fadvise50 system call changed assembly stub type. You
                    125:        need to 'rm -f __posix_fadvise50.*' in the libc build directory
                    126:        to avoid using the old assembly stub.
1.192     skrll     127:
1.191     joerg     128: 20090202:
                    129:        pkg_install now depends on the pkgdb cache for automatic conflict
                    130:        detection.  It is recommented to rebuild the cache with
                    131:        ``pkg_admin rebuild''.

1.184     christos  133: 20090110:
                    134:        time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
                    135:        1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188     christos  136:           This is needed even in the MODULAR kernel because there is
                    137:           conditionally compiled code in rtsock.c.
1.184     christos  138:        2. make sure build.sh completes and the binaries in a chroot work
                    139:           before installing.
                    140:        3. If you don't use build.sh and you build directly to root, and
1.187     dholland  141:           your build breaks in the middle, don't despair. Make sure headers
1.184     christos  142:           are installed properly, and start building libraries first libc
                    143:           and libutil, install them and then continue building all the
                    144:           libraries in src/lib and src/gnu/lib and install them. Once
                    145:           the new libraries are installed, you can restart the build.
                    146:        4. If you compile packages and you notice link time warnings,
1.189     hubertf   147:           rebuild the required packages to update their shared libraries.
                    148:           Any package you rebuild will require rebuilding all the packages
                    149:           that depend on it.
1.186     christos  150:        5. Next time you run pwd_mkdb with the new binary, the file
                    151:           will be upgraded and it will not be backwards compatible.
1.190     apb       152:        6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
                    153:           lastlogx(5)) have been versioned, and there is a heuristic
                    154:           for utmp. You are better off removing the old files after
                    155:           upgrading.  The automated clearing of /var/run during
                    156:           boot, and the automated rotating of files in /var/log by
                    157:           newsyslog(8), may mean that you do not have to remove the
                    158:           files manually.
                    159:        7. The optional accounting file (/var/account/acct, see
                    160:           accton(8)) has not been versioned, and will need to be
                    161:           removed.  The automatic rotation of the accounting file by
                    162:           /etc/daily limits the bad consequences of failure to remove
                    163:           the file.
1.196     dholland  164:        8. Application software that writes time_t to binary files on
                    165:           disk will break or need attention. Most notably: if you are
                    166:           using PostgreSQL < 8.4, you need to dump your databases,
                    167:           rebuild PostgreSQL with the new time_t, then restore.

                    172:        (done automatically by build.sh) and then you need to rerun
                    173:        config on all kernel configuration files before rebuilding those
