                     27:        New share/mk files needed to support .WAIT in SUBDIR variables.
                     28:        If you get make errors,

                     30:        Also, PRINTOBJDIR has changed and is now used more heavily.

1.6       ad         34:        major and minor numbers haven't changed, you should update your /dev

1.4       itojun     37: 20000929:
                     38:        The following make directives are obsoleted.
                     39:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA

1.16      wiz        41:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun     42:        additional library libcrypto_{idea,rc5}.
                     43:
1.1       abs        44: 20000623:
                     45:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     46:        'cd share/mk ; make install' needed before make build.
                     47:
                     48:
                     49: Hints for a more successful build:
                     50: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        51:     Build a new kernel first:
                     52:        This makes sure that any new system calls or features
                     53:           expected by the new userland will be present.  This
                     54:           helps to avoid critical errors when upgrading.
1.1       abs        55:     Use object directories:
                     56:        This helps to keep stale object
                     57:           files from polluting the build if a Makefile "forgets"
                     58:           about one.  It also makes it easier to clean up after
                     59:           a build.  It's also necessary if you want to use the
                     60:           same source tree for multiple machines.
                     61:           To use object directories:
                     62:            a) cd /usr/src ; make cleandir
1.2       mrg        63:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                     64:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs        65:            d) cd /usr/src ; make build
1.2       mrg        66:           Note that running "make obj" in a directory will create
                     67:           in obj.$MACHINE directory.
1.1       abs        68:     Build to a DESTDIR:
                     69:        This helps to keep old
                     70:           installed files (especially libraries) from interfering
                     71:           with the new build.
                     72:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg        73:           variable before running make build.  It should be set to
                     74:           the pathname of an initially empty directory.
1.1       abs        75:           Problems: you might need to update critical utilities
                     76:                without using DESTDIR since nothing is executed
                     77:                from what is installed in DESTDIR.
                     78:                (See critical utils, below)
                     79:     Build often:
                     80:        This keeps critical utilities current enough to not choke
                     81:        on any other part of the source tree that depends on up to
                     82:        date functionality.
                     83:
                     84: What to do if things don't work:
                     85: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                     86: When things don't work there is usually a few things that commonly
                     87: should be done.
                     88:     1) make includes
                     89:        This should be done automatically by make build.
                     90:     2)  cd share/mk && make install
                     91:        Again, automatically done by make build.
                     92:
                     93: Failsafe rebuild of a small part of the tree:
                     94: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                     95: To make sure you rebuild something correctly you want to do
                     96: something like the following:
                     97:     1)  Make sure the includes and .mk files are up to date.
                     98:     2)  Make sure any program used to build the particular
                     99:        utility is up to date.  (yacc, lex, etc...)
                    100:     3)  cd ...path/to/util...
                    101:        make cleandir
                    102:        rm ...all obj directories...
                    103:        make cleandir                   # yes, again
                    104:        make obj
                    105:        make depend && make
                    106:
                    107: Failsafe rebuild of the entire tree:
                    108: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    109: If you really want to make sure the source tree is clean and
1.2       mrg       110: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    111: (a make(1) Makefile) in this manner is not right, and will not work
                    112: for anyone who uses any make(1) features in /etc/mk.conf.
