                      3: This file is intended to be a brief introduction to the build
                      4: process and a reference on what to do if something doesn't work.

        !            13:        code has been deprecated to COMPAT_16. Make sure that your running

                     23:        build the included texinfo files, do:

                     36:        Due to bugs in the export handling code, invalid export lines
                     37:        were accepted before and caused the kernel to panic when
                     38:        mountd got restarted because it freed memory that had already
                     39:        been freed. This has been fixed and the kernel checks
                     40:        export addresses very strictly. If you upgrade your kernel,
                     41:        make sure you also upgrade mountd, because if your export
                     42:        file contains lines with an old inet4 address syntax (i.e.
                     43:        a.b.c or a.b or a), they will get rejected by the new kernel.

                     46:        The superblock layout for FFS was changed.  If you have 1.6
                     47:        fsck binaries, they will signal a fatal superblock mismatch
                     48:        with the first alternate, because they compare too many
                     49:        fields (even ones that aren't useful).  If possible, upgrade
                     50:        your fsck_ffs binary before using a new kernel.
                     51:        None of this signals actual filesystem damage.

                     54:        sendmail version 8.12.8 was imported.  Since sendmail is
                     55:        now setgid to the smmsp group, and runs in "collection"
                     56:        mode for most common activities, there is a new config
                     57:        file called submit.cf that needs to live in /etc/mail.

                     59:        is named netbsd-msp.cf.  Upgrading your regular sendmail
                     60:        configuration file is also strongly advised.
                     61:
                     62:        See the section named "MESSAGE SUBMISSION PROGRAM" in

                     64:        information.

                     75:        "${DESTDIR}" from path names.
                     76:        This only affects people building with UNPRIVED.
                     77:        For complete safety, remove the DESTDIR entirely and
                     78:        update tools/mtree, before running make build.

                     89:        of the host system passwd(5) and group(5) databases).
                     90:
                     91:        The build system was modified to take advantage of
                     92:        this option (using ${NETBSDSRCDIR}/etc), so if you
1.83      kei        93:        use USETOOLS==no, you may have to rebuild and

                     98:        If building to DESTDIR=/, reinstall the includes
                     99:        and rebuild libc:

                    107:        including the optional "SYS_INCLUDE=symlinks" support.
                    108:        All header files, including <sys/*.h> are copied into

                    111: 20021121:
                    112:        The C run-time support files crtbegin.o and crtend.o
                    113:        (and their companions crtbeginS.o and crtendS.o) were
                    114:        split up, with new crti.o and crtn.o files resulting.
                    115:        This means that libtool needs to be rebuilt once the
                    116:        new libraries are installed.  The process of rebuilding
                    117:        libtool will cause it to automatically notice the new
                    118:        required files, but it *must* be rebuilt in order to
                    119:        do this.
                    120:
                    121:        An out-of-date libtool will result in shared libraries
                    122:        which lack _init() and _fini() routines, which means that
                    123:        their global contructors/destructors will not be invoked.
1.75      thorpej   124:

                    126:        A bug related to how ARM ELF objects were tagged has been
                    127:        corrected.
                    128:
                    129:        NetBSD ARM ELF uses the soft-VFP floating point model by
                    130:        default.  However, the assembler lacked support for marking
                    131:        objects as using the VFP floating point format, and the
1.79      wiz       132:        compiler was not properly passing the flag indicating "soft-VFP"
1.75      thorpej   133:        to the assembler.
                    134:
                    135:        Unfortunately, this means that the linker will now consider
                    136:        old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
                    137:        incompatible with new (properly marked) objects.
                    138:
                    139:        The problem will only manifest itself if you attempt to compile
                    140:        a new program using the fixed toolchain, and link that program
                    141:        against old libraries which do not have the proper "softvfp"
                    142:        markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
                    143:        WILL CONTINUE TO WORK PROPERLY.
                    144:
                    145:        The only work-around for the problem is to recompile all of
                    146:        the libraries on the system.  The easiest way to do this for
1.79      wiz       147:        system libraries is to install a binary snapshot; they are
1.93      salo      148:        generally available on releng.NetBSD.org.  Any packages you
1.75      thorpej   149:        have installed which supply libraries will have to be recompiled
                    150:        if you wish to link new programs against those libraries.
