                     36:        If you get make errors,
                     37:                (cd share/mk; make install)
                     38:        Also, PRINTOBJDIR has changed and is now used more heavily.

1.6       ad         42:        major and minor numbers haven't changed, you should update your /dev

                     46:        The following make directives are obsoleted.
                     47:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     48:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        49:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun     50:        additional library libcrypto_{idea,rc5}.

                     53:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     54:        'cd share/mk ; make install' needed before make build.
                     55:
                     56:
                     57: Hints for a more successful build:
                     58: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        59:     Build a new kernel first:
                     60:        This makes sure that any new system calls or features
                     61:           expected by the new userland will be present.  This
                     62:           helps to avoid critical errors when upgrading.
1.1       abs        63:     Use object directories:
                     64:        This helps to keep stale object
                     65:           files from polluting the build if a Makefile "forgets"
                     66:           about one.  It also makes it easier to clean up after
                     67:           a build.  It's also necessary if you want to use the
                     68:           same source tree for multiple machines.
                     69:           To use object directories:
                     70:            a) cd /usr/src ; make cleandir
1.2       mrg        71:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                     72:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs        73:            d) cd /usr/src ; make build
1.2       mrg        74:           Note that running "make obj" in a directory will create
                     75:           in obj.$MACHINE directory.
1.1       abs        76:     Build to a DESTDIR:
                     77:        This helps to keep old
                     78:           installed files (especially libraries) from interfering
                     79:           with the new build.
                     80:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg        81:           variable before running make build.  It should be set to
                     82:           the pathname of an initially empty directory.
1.1       abs        83:           Problems: you might need to update critical utilities
                     84:                without using DESTDIR since nothing is executed
                     85:                from what is installed in DESTDIR.
                     86:                (See critical utils, below)
                     87:     Build often:
                     88:        This keeps critical utilities current enough to not choke
                     89:        on any other part of the source tree that depends on up to
                     90:        date functionality.
                     91:
                     92: What to do if things don't work:
                     93: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                     94: When things don't work there is usually a few things that commonly
                     95: should be done.
                     96:     1) make includes
                     97:        This should be done automatically by make build.
                     98:     2)  cd share/mk && make install
                     99:        Again, automatically done by make build.
                    100:
                    101: Failsafe rebuild of a small part of the tree:
                    102: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    103: To make sure you rebuild something correctly you want to do
                    104: something like the following:
                    105:     1)  Make sure the includes and .mk files are up to date.
                    106:     2)  Make sure any program used to build the particular
                    107:        utility is up to date.  (yacc, lex, etc...)
                    108:     3)  cd ...path/to/util...
                    109:        make cleandir
                    110:        rm ...all obj directories...
                    111:        make cleandir                   # yes, again
                    112:        make obj
                    113:        make depend && make
                    114:
                    115: Failsafe rebuild of the entire tree:
                    116: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    117: If you really want to make sure the source tree is clean and
1.2       mrg       118: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    119: (a make(1) Makefile) in this manner is not right, and will not work
                    120: for anyone who uses any make(1) features in /etc/mk.conf.
