                      3: This file is intended to be a brief introduction to the build

                     13:        Enabled correct .init/.fini processing in crt0.  The way this
                     14:        was done was to change a -I directive to cc(1), which means
                     15:        make(1) will have a stale dependency (it will be checking the
                     16:        timestamp on the wrong "dot_init.h").
                     17:
                     18:        The symptom you will see is that new programs die with SIGSEGV
                     19:        if you have a stale dependency.
                     20:
                     21:        Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
                     22:        before starting your build.

        !            26:        A construct was added to uvm_page.h that uncovered a bug
        !            27:        in lint(1).  If you get a warning/error about a non-portable
        !            28:        bitfield, update your lint(1) before proceeding.

                     34:

1.20      jmc        49:         to be bootstrapped manually until the host system is current.
1.18      jmc        50:

1.23      tron       65:        anything make and install in usr.bin/make, then proceed

1.8       sommerfe   71:
                     72: 20001230:
                     73:        New share/mk files needed to support .WAIT in SUBDIR variables.
                     74:        If you get make errors,
                     75:                (cd share/mk; make install)
                     76:        Also, PRINTOBJDIR has changed and is now used more heavily.

                     78: 20001019:
1.7       ad         79:        The `ca' device driver has been replaced by `ld'; although the
1.6       ad         80:        major and minor numbers haven't changed, you should update your /dev
                     81:        directory.
1.1       abs        82:
1.4       itojun     83: 20000929:
                     84:        The following make directives are obsoleted.
                     85:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     86:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        87:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun     88:        additional library libcrypto_{idea,rc5}.
                     89:
1.1       abs        90: 20000623:
                     91:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     92:        'cd share/mk ; make install' needed before make build.
                     93:
                     94:
                     95: Hints for a more successful build:
                     96: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        97:     Build a new kernel first:
                     98:        This makes sure that any new system calls or features
                     99:           expected by the new userland will be present.  This
                    100:           helps to avoid critical errors when upgrading.
1.1       abs       101:     Use object directories:
                    102:        This helps to keep stale object
                    103:           files from polluting the build if a Makefile "forgets"
                    104:           about one.  It also makes it easier to clean up after
                    105:           a build.  It's also necessary if you want to use the
                    106:           same source tree for multiple machines.
                    107:           To use object directories:
                    108:            a) cd /usr/src ; make cleandir
1.2       mrg       109:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    110:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs       111:            d) cd /usr/src ; make build
1.2       mrg       112:           Note that running "make obj" in a directory will create
                    113:           in obj.$MACHINE directory.
1.1       abs       114:     Build to a DESTDIR:
                    115:        This helps to keep old
                    116:           installed files (especially libraries) from interfering
                    117:           with the new build.
                    118:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       119:           variable before running make build.  It should be set to
                    120:           the pathname of an initially empty directory.
1.1       abs       121:           Problems: you might need to update critical utilities
                    122:                without using DESTDIR since nothing is executed
                    123:                from what is installed in DESTDIR.
                    124:                (See critical utils, below)
                    125:     Build often:
                    126:        This keeps critical utilities current enough to not choke
                    127:        on any other part of the source tree that depends on up to
                    128:        date functionality.
                    129:
                    130: What to do if things don't work:
                    131: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    132: When things don't work there is usually a few things that commonly
                    133: should be done.
                    134:     1) make includes
                    135:        This should be done automatically by make build.
                    136:     2)  cd share/mk && make install
                    137:        Again, automatically done by make build.
                    138:
                    139: Failsafe rebuild of a small part of the tree:
                    140: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    141: To make sure you rebuild something correctly you want to do
                    142: something like the following:
                    143:     1)  Make sure the includes and .mk files are up to date.
                    144:     2)  Make sure any program used to build the particular
                    145:        utility is up to date.  (yacc, lex, etc...)
                    146:     3)  cd ...path/to/util...
                    147:        make cleandir
                    148:        rm ...all obj directories...
                    149:        make cleandir                   # yes, again
                    150:        make obj
                    151:        make depend && make
                    152:
                    153: Failsafe rebuild of the entire tree:
                    154: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    155: If you really want to make sure the source tree is clean and
1.2       mrg       156: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    157: (a make(1) Makefile) in this manner is not right, and will not work
                    158: for anyone who uses any make(1) features in /etc/mk.conf.
