                      4: process and a reference on what to do if something doesn't work.

                     12:        introduce .if commands(target) in make(1). You need to
                     13:        bring everything up-to-date first, then without installing
                     14:        anything make and install in /usr/bin/make, then proceed
                     15:        with make build.

                     17: 20010101:
                     18:        bsd.subdir.mk committed 20001230 had a bug which caused
                     19:        afterinstall targets to run too soon; update again.
1.8       sommerfe   20:
                     21: 20001230:
                     22:        New share/mk files needed to support .WAIT in SUBDIR variables.
                     23:        If you get make errors,
                     24:                (cd share/mk; make install)
                     25:        Also, PRINTOBJDIR has changed and is now used more heavily.

                     27: 20001019:
1.7       ad         28:        The `ca' device driver has been replaced by `ld'; although the
1.6       ad         29:        major and minor numbers haven't changed, you should update your /dev
                     30:        directory.

1.4       itojun     32: 20000929:
                     33:        The following make directives are obsoleted.
                     34:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     35:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
                     36:        bulit into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
                     37:        additional library libcrypto_{idea,rc5}.
                     38:
1.1       abs        39: 20000623:
                     40:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     41:        'cd share/mk ; make install' needed before make build.
                     42:
                     43:
                     44: Hints for a more successful build:
                     45: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        46:     Build a new kernel first:
                     47:        This makes sure that any new system calls or features
                     48:           expected by the new userland will be present.  This
                     49:           helps to avoid critical errors when upgrading.
1.1       abs        50:     Use object directories:
                     51:        This helps to keep stale object
                     52:           files from polluting the build if a Makefile "forgets"
                     53:           about one.  It also makes it easier to clean up after
                     54:           a build.  It's also necessary if you want to use the
                     55:           same source tree for multiple machines.
                     56:           To use object directories:
                     57:            a) cd /usr/src ; make cleandir
1.2       mrg        58:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                     59:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs        60:            d) cd /usr/src ; make build
1.2       mrg        61:           Note that running "make obj" in a directory will create
                     62:           in obj.$MACHINE directory.
1.1       abs        63:     Build to a DESTDIR:
                     64:        This helps to keep old
                     65:           installed files (especially libraries) from interfering
                     66:           with the new build.
                     67:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg        68:           variable before running make build.  It should be set to
                     69:           the pathname of an initially empty directory.
1.1       abs        70:           Problems: you might need to update critical utilities
                     71:                without using DESTDIR since nothing is executed
                     72:                from what is installed in DESTDIR.
                     73:                (See critical utils, below)
                     74:     Build often:
                     75:        This keeps critical utilities current enough to not choke
                     76:        on any other part of the source tree that depends on up to
                     77:        date functionality.
                     78:
                     79: What to do if things don't work:
                     80: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                     81: When things don't work there is usually a few things that commonly
                     82: should be done.
                     83:     1) make includes
                     84:        This should be done automatically by make build.
                     85:     2)  cd share/mk && make install
                     86:        Again, automatically done by make build.
                     87:
                     88: Failsafe rebuild of a small part of the tree:
                     89: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                     90: To make sure you rebuild something correctly you want to do
                     91: something like the following:
                     92:     1)  Make sure the includes and .mk files are up to date.
                     93:     2)  Make sure any program used to build the particular
                     94:        utility is up to date.  (yacc, lex, etc...)
                     95:     3)  cd ...path/to/util...
                     96:        make cleandir
                     97:        rm ...all obj directories...
                     98:        make cleandir                   # yes, again
                     99:        make obj
                    100:        make depend && make
                    101:
                    102: Failsafe rebuild of the entire tree:
                    103: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    104: If you really want to make sure the source tree is clean and
1.2       mrg       105: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    106: (a make(1) Makefile) in this manner is not right, and will not work
                    107: for anyone who uses any make(1) features in /etc/mk.conf.
