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.

1.134   ! christos   18: 20050109:
        !            19:        Since su is using pam by default now, make sure that you have
        !            20:        /etc/pam.d populated (postinstall will do that automatically
        !            21:        for you). Otherwise su will fail open (i.e. will not require
        !            22:        a password).

1.133     christos   24: 20041229:
                     25:        Make had a path resolution bug that manifested itself as not
                     26:        being able to install openpam.3. This bug has been fixed, but
                     27:        you might need to rebuild make manually first to get through
                     28:        the build.

1.130     christos   30: 20041201:
                     31:        Userland programs have been changed to use /dev/bpf instead of
                     32:        /dev/bpfX. You need to create that device by installing a new
1.131     wiz        33:        MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*

1.129     jmc        35: 20041006:
                     36:
                     37:        A bug was introduced into /bin/sh (var.c rev 1.35) which causes
                     38:        variables to not export correctly to subshells in all cases. This
                     39:        will cause builds to break if that version of /bin/sh is installed
                     40:        on the system. The proper version of /bin/sh can be verified with:
                     41:
                     42:         ident /bin/sh | grep var
                     43:
                     44:        Any /bin/sh w. version 1.35 will not work and needs to be updated
                     45:        before attempting a build.
                     46:
1.127     christos   47: 20041001:
                     48:        The ipfilter kernel sources moved from sys/netinet to
                     49:        dist/sys/ipf/netinet. Due to the move some Makefile
                     50:        dependencies are now dangling requiring a make cleandir
1.128     he         51:        before they work again (kdump, ktruss, rescue, ipf, and
                     52:        ftp-proxy are the victims).

1.125     atatat     54: 20040715:
                     55:        The rc.d/sendmail script now uses a heuristic to determine
                     56:        if sendmail should be started at boot time.  It checks the
                     57:        contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
                     58:        owner and mode of the sendmail binary to see if any changes
                     59:        to the mail infrastructure have been made.  If no changes
                     60:        are detected, it will start an SMTP listener.
                     61:
                     62:        Setting sendmail=NO in /etc/rc.conf will override this.
                     63:
                     64:        If you are only using sendmail by default and only for
                     65:        local delivery, it is important that you also update your
                     66:        sendmail.cf so that the SMTP listener only listens on the
                     67:        loopback interface.
                     68:
                     69: 20040715:
                     70:        The method by which athhal-elf.o gets pulled into i386
                     71:        kernel builds has been changed again.  The latest version
                     72:        of bsd.files.mk is no longer required.
                     73:
1.124     jmc        74: 20040621:
                     75:        Due to the recent rototill of tools/compat it's crucial one starts
                     76:        from a clean objdir under tools/*.
                     77:
                     78:        This is mostly due to generated files (yacc and lex sources) needing
1.125     atatat     79:        to be generated with new rules from bsd.hostprog.mk.
1.124     jmc        80:
                     81:        The safest course is to rm -rf all objects under tools before building.
                     82:
1.121     lukem      83: 20040516:
                     84:        The end-user modifiable X11 configuration has been moved
                     85:        from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
                     86:        Ensure that src and xsrc is up to date, and run
                     87:        "make cleandir" in src/x11 before your next build.
                     88:
1.126     lukem      89:        postinstall currently doesn't migrate the files from
                     90:        /usr/X11R6/lib/X11/* to /etc/X11/* although it does
                     91:        detect that this needs to occur, so you'll have to
                     92:        manually move these files yourself.
                     93:
1.119     atatat     94: 20040426:
                     95:        Support for the original dynamic sysctl node structure has
                     96:        been removed in favor of the newer layout.  This affects
                     97:        consumers of the create and delete interface, as well as
                     98:        the dynamic discovery mechanism.  This is believed only to
                     99:        be the sysctl(8) binary itself, at this point in time, so
                    100:        the only effect of this should be that a sysctl binary
                    101:        built from sources dated between 2003/12/04 and 2004/03/24
                    102:        will not work on a kernel built from sources dated after
                    103:        2004/04/25.  If you need a new sysctl binary but build.sh
                    104:        does not work, make sure that your revision of
1.120     atatat    105:        src/sys/sys/sysctl.h is 1.112 (or later), and then the
                    106:        do the following:
1.119     atatat    107:
1.120     atatat    108:        cd /usr/src (or wherever your source tree is)
                    109:        make USETOOLS=no includes

1.119     atatat    113:        make USETOOLS=no dependall install
                    114:
1.122     itojun    115:        If you are using older sysctl binary, GNU autoconf would fail to
                    116:        identify your machine architecture, and tries to build binary for
                    117:        "unknown-unknown-netbsd20F" or something like that.  if that happens,
                    118:        make sure to follow the above steps.

                    121:        The ffs superblock issues listed below under 20040109 and 20030402
                    122:        are now automatically addressed by the /etc/rc.d/fixsb script or by
                    123:        sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
                    124:        invocation mentioned below will continue to work and is now
                    125:        automated by those scripts.  Note that under certain circumstances,
                    126:        affected filesystems upgraded to a -current kernel first before
                    127:        upgrading their userland with the fixsb and fsck_ffs fixes may
                    128:        encounter a 'freeing free inode' panic when writing to the affected
                    129:        filesystem, so it is a good idea to repair the filesystem as soon as
                    130:        possible.  For more details on the fixsb script, see pr install/25138.

1.117     jmc       143:        has been changed. The file is now stored as a uuencoded file in CVS
1.114     jmc       144:        and the generated Makefile will use the new .uue rules from bsd.file.mk

                    666: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123     jmc       667:     Use build.sh, but do not use its "expert mode":
1.132     jmmv      668:        This will automatically build the tools in the
1.123     jmc       669:           correct order, and it will keep the tools and the
                    670:           new build products from interfering with the running
                    671:           system.  This will allow you to ignore most of the
                    672:           other advice in this file.
1.2       mrg       673:     Build a new kernel first:
                    674:        This makes sure that any new system calls or features
                    675:           expected by the new userland will be present.  This
                    676:           helps to avoid critical errors when upgrading.
1.1       abs       677:     Use object directories:
                    678:        This helps to keep stale object

                    680:           about one.  It also makes it easier to clean up after
                    681:           a build.  It's also necessary if you want to use the
                    682:           same source tree for multiple machines.
1.123     jmc       683:           To use object directories with build.sh:
                    684:            a) invoke build.sh with the "-M" or "-O" options.
                    685:           To use object directories without using build.sh:

1.1       abs       692:     Build to a DESTDIR:
1.123     jmc       693:        This helps to keep old installed files (especially libraries)
                    694:           from interfering with the new build.
                    695:           To build to a DESTDIR with build.sh, use the "-D" option.
                    696:           To build to a DESTDIR without using build.sh, set the DESTDIR
                    697:           environment variable before running make build.  It should be
                    698:           set to the pathname of an initially empty directory.
                    699:           Problems: if you do not use build.sh, you might need to
                    700:                update critical utilities without using DESTDIR since
                    701:                nothing is executed from what is installed in DESTDIR.
