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 the following platforms no longer use -tradition-cpp:
        !            20:        - Alpha,
        !            21:        - AMD64,

        !            24:        - SPARC64.
1.218     joerg      25:        This can break the build of individual parts of the tree.  This is
                     26:        handled correctly by build.sh.  Manual builds have to update
                     27:        /usr/share/mk and re-run config(1) for any kernel configurations as
                     28:        needed.

                     31:        The tcpdump(8) program was changed to drop privileges and chroot(2)
                     32:        by default. It may be necessary to manually update passwd(5) and
                     33:        group(5) in order to make the program work with existing setups.

                     37:        variables with names that contain '='. Revision 1.18 of env.c
                     38:        assumed that this was allowed. Installing a new libc with an
                     39:        old copy of /usr/bin/env causes env x=1 printenv | grep x= to
                     40:        break which affects the autoconf tests for dependency finding,
                     41:        so building gcc will end up printing:
                     42:            checking dependency style of gcc... none
                     43:            configure: error: no usable dependency style found
                     44:        Fix it by rebuilding and re-installing env.

                     80:        from the system when upgrading.

1.206     dholland   91:        On amd64 you must rebuild tools (to get the new binutils)

                    101:        point for index(). Update build of libc.a (and libc_pic.a)
                    102:        may fail because the archive contains the unwanted index.o.

                    118:        can cause autoconf problems during the tool build for people
                    119:        who fail to clean out their tools objects properly. If you

1.207     mbalmer   129:        The __posix_fadvise50 system call changed assembly stub type. You
                    130:        need to 'rm -f __posix_fadvise50.*' in the libc build directory
                    131:        to avoid using the old assembly stub.

                    134:        pkg_install now depends on the pkgdb cache for automatic conflict
                    135:        detection.  It is recommented to rebuild the cache with
                    136:        ``pkg_admin rebuild''.

                    139:        time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
                    140:        1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188     christos  141:           This is needed even in the MODULAR kernel because there is
                    142:           conditionally compiled code in rtsock.c.
1.184     christos  143:        2. make sure build.sh completes and the binaries in a chroot work
                    144:           before installing.
                    145:        3. If you don't use build.sh and you build directly to root, and
1.187     dholland  146:           your build breaks in the middle, don't despair. Make sure headers
1.184     christos  147:           are installed properly, and start building libraries first libc
                    148:           and libutil, install them and then continue building all the
                    149:           libraries in src/lib and src/gnu/lib and install them. Once
                    150:           the new libraries are installed, you can restart the build.
                    151:        4. If you compile packages and you notice link time warnings,
1.189     hubertf   152:           rebuild the required packages to update their shared libraries.
                    153:           Any package you rebuild will require rebuilding all the packages
                    154:           that depend on it.
1.186     christos  155:        5. Next time you run pwd_mkdb with the new binary, the file
                    156:           will be upgraded and it will not be backwards compatible.
1.190     apb       157:        6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
                    158:           lastlogx(5)) have been versioned, and there is a heuristic
                    159:           for utmp. You are better off removing the old files after
                    160:           upgrading.  The automated clearing of /var/run during
                    161:           boot, and the automated rotating of files in /var/log by
                    162:           newsyslog(8), may mean that you do not have to remove the
                    163:           files manually.
                    164:        7. The optional accounting file (/var/account/acct, see
                    165:           accton(8)) has not been versioned, and will need to be
                    166:           removed.  The automatic rotation of the accounting file by
                    167:           /etc/daily limits the bad consequences of failure to remove
                    168:           the file.
1.196     dholland  169:        8. Application software that writes time_t to binary files on
                    170:           disk will break or need attention. Most notably: if you are
                    171:           using PostgreSQL < 8.4, you need to dump your databases,
                    172:           rebuild PostgreSQL with the new time_t, then restore.

                    177:        (done automatically by build.sh) and then you need to rerun
