1.6       ad         55:        major and minor numbers haven't changed, you should update your /dev

1.4       itojun     58: 20000929:
                     59:        The following make directives are obsoleted.
                     60:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     61:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        62:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun     63:        additional library libcrypto_{idea,rc5}.
                     64:
1.1       abs        65: 20000623:
                     66:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     67:        'cd share/mk ; make install' needed before make build.
                     68:
                     69:
                     70: Hints for a more successful build:
                     71: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        72:     Build a new kernel first:
                     73:        This makes sure that any new system calls or features
                     74:           expected by the new userland will be present.  This
                     75:           helps to avoid critical errors when upgrading.
1.1       abs        76:     Use object directories:
                     77:        This helps to keep stale object
                     78:           files from polluting the build if a Makefile "forgets"
                     79:           about one.  It also makes it easier to clean up after
                     80:           a build.  It's also necessary if you want to use the
                     81:           same source tree for multiple machines.
                     82:           To use object directories:
                     83:            a) cd /usr/src ; make cleandir
1.2       mrg        84:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                     85:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs        86:            d) cd /usr/src ; make build
1.2       mrg        87:           Note that running "make obj" in a directory will create
                     88:           in obj.$MACHINE directory.
1.1       abs        89:     Build to a DESTDIR:
                     90:        This helps to keep old
                     91:           installed files (especially libraries) from interfering
                     92:           with the new build.
                     93:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg        94:           variable before running make build.  It should be set to
                     95:           the pathname of an initially empty directory.
1.1       abs        96:           Problems: you might need to update critical utilities
                     97:                without using DESTDIR since nothing is executed
                     98:                from what is installed in DESTDIR.
                     99:                (See critical utils, below)
                    100:     Build often:
                    101:        This keeps critical utilities current enough to not choke
                    102:        on any other part of the source tree that depends on up to
                    103:        date functionality.
                    104:
                    105: What to do if things don't work:
                    106: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    107: When things don't work there is usually a few things that commonly
                    108: should be done.
                    109:     1) make includes
                    110:        This should be done automatically by make build.
                    111:     2)  cd share/mk && make install
                    112:        Again, automatically done by make build.
                    113:
                    114: Failsafe rebuild of a small part of the tree:
                    115: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    116: To make sure you rebuild something correctly you want to do
                    117: something like the following:
                    118:     1)  Make sure the includes and .mk files are up to date.
                    119:     2)  Make sure any program used to build the particular
                    120:        utility is up to date.  (yacc, lex, etc...)
                    121:     3)  cd ...path/to/util...
                    122:        make cleandir
                    123:        rm ...all obj directories...
                    124:        make cleandir                   # yes, again
                    125:        make obj
                    126:        make depend && make
                    127:
                    128: Failsafe rebuild of the entire tree:
                    129: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    130: If you really want to make sure the source tree is clean and
1.2       mrg       131: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    132: (a make(1) Makefile) in this manner is not right, and will not work
                    133: for anyone who uses any make(1) features in /etc/mk.conf.
