                      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:        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.

1.21      jmc        27:        will break as mtree aborts early.
                     28:

                     38:
                     39:        Now a make build should progress.

                     42:        get/setprogname() added. Any hostprog's that may use this will need
1.20      jmc        43:         to be bootstrapped manually until the host system is current.
1.18      jmc        44:

1.23      tron       59:        anything make and install in usr.bin/make, then proceed

1.8       sommerfe   65:
                     66: 20001230:
                     67:        New share/mk files needed to support .WAIT in SUBDIR variables.
                     68:        If you get make errors,
                     69:                (cd share/mk; make install)
                     70:        Also, PRINTOBJDIR has changed and is now used more heavily.

1.6       ad         74:        major and minor numbers haven't changed, you should update your /dev

1.1       abs        76:
1.4       itojun     77: 20000929:
                     78:        The following make directives are obsoleted.
                     79:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     80:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        81:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun     82:        additional library libcrypto_{idea,rc5}.
                     83:
1.1       abs        84: 20000623:
                     85:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     86:        'cd share/mk ; make install' needed before make build.

                     88:
                     89: Hints for a more successful build:
                     90: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        91:     Build a new kernel first:
                     92:        This makes sure that any new system calls or features
                     93:           expected by the new userland will be present.  This
                     94:           helps to avoid critical errors when upgrading.
1.1       abs        95:     Use object directories:
                     96:        This helps to keep stale object
                     97:           files from polluting the build if a Makefile "forgets"
                     98:           about one.  It also makes it easier to clean up after
                     99:           a build.  It's also necessary if you want to use the
                    100:           same source tree for multiple machines.
                    101:           To use object directories:
                    102:            a) cd /usr/src ; make cleandir
1.2       mrg       103:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    104:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs       105:            d) cd /usr/src ; make build
1.2       mrg       106:           Note that running "make obj" in a directory will create
                    107:           in obj.$MACHINE directory.
1.1       abs       108:     Build to a DESTDIR:
                    109:        This helps to keep old
                    110:           installed files (especially libraries) from interfering
                    111:           with the new build.
                    112:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       113:           variable before running make build.  It should be set to
                    114:           the pathname of an initially empty directory.
1.1       abs       115:           Problems: you might need to update critical utilities
                    116:                without using DESTDIR since nothing is executed
                    117:                from what is installed in DESTDIR.
                    118:                (See critical utils, below)
                    119:     Build often:
                    120:        This keeps critical utilities current enough to not choke
                    121:        on any other part of the source tree that depends on up to
                    122:        date functionality.
                    123:
                    124: What to do if things don't work:
                    125: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    126: When things don't work there is usually a few things that commonly
                    127: should be done.
                    128:     1) make includes
                    129:        This should be done automatically by make build.
                    130:     2)  cd share/mk && make install
                    131:        Again, automatically done by make build.
                    132:
                    133: Failsafe rebuild of a small part of the tree:
                    134: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    135: To make sure you rebuild something correctly you want to do
                    136: something like the following:
                    137:     1)  Make sure the includes and .mk files are up to date.
                    138:     2)  Make sure any program used to build the particular
                    139:        utility is up to date.  (yacc, lex, etc...)
                    140:     3)  cd ...path/to/util...
                    141:        make cleandir
                    142:        rm ...all obj directories...
                    143:        make cleandir                   # yes, again
                    144:        make obj
                    145:        make depend && make
                    146:
                    147: Failsafe rebuild of the entire tree:
                    148: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    149: If you really want to make sure the source tree is clean and
1.2       mrg       150: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    151: (a make(1) Makefile) in this manner is not right, and will not work
                    152: for anyone who uses any make(1) features in /etc/mk.conf.
