                      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.

1.21      jmc        14:        will break as mtree aborts early.
                     15:

                     29:        get/setprogname() added. Any hostprog's that may use this will need

                     44:        introduce .if commands(target) in make(1). You need to

1.23    ! tron       46:        anything make and install in usr.bin/make, then proceed

                     54:        New share/mk files needed to support .WAIT in SUBDIR variables.
                     55:        If you get make errors,
                     56:                (cd share/mk; make install)
                     57:        Also, PRINTOBJDIR has changed and is now used more heavily.

1.6       ad         61:        major and minor numbers haven't changed, you should update your /dev

1.4       itojun     64: 20000929:
                     65:        The following make directives are obsoleted.
                     66:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     67:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        68:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun     69:        additional library libcrypto_{idea,rc5}.
                     70:
1.1       abs        71: 20000623:
                     72:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                     73:        'cd share/mk ; make install' needed before make build.
                     74:
                     75:
                     76: Hints for a more successful build:
                     77: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg        78:     Build a new kernel first:
                     79:        This makes sure that any new system calls or features
                     80:           expected by the new userland will be present.  This
                     81:           helps to avoid critical errors when upgrading.
1.1       abs        82:     Use object directories:
                     83:        This helps to keep stale object
                     84:           files from polluting the build if a Makefile "forgets"
                     85:           about one.  It also makes it easier to clean up after
                     86:           a build.  It's also necessary if you want to use the
                     87:           same source tree for multiple machines.
                     88:           To use object directories:
                     89:            a) cd /usr/src ; make cleandir
1.2       mrg        90:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                     91:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs        92:            d) cd /usr/src ; make build
1.2       mrg        93:           Note that running "make obj" in a directory will create
                     94:           in obj.$MACHINE directory.
1.1       abs        95:     Build to a DESTDIR:
                     96:        This helps to keep old
                     97:           installed files (especially libraries) from interfering
                     98:           with the new build.
                     99:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       100:           variable before running make build.  It should be set to
                    101:           the pathname of an initially empty directory.
1.1       abs       102:           Problems: you might need to update critical utilities
                    103:                without using DESTDIR since nothing is executed
                    104:                from what is installed in DESTDIR.
                    105:                (See critical utils, below)
                    106:     Build often:
                    107:        This keeps critical utilities current enough to not choke
                    108:        on any other part of the source tree that depends on up to
                    109:        date functionality.
                    110:
                    111: What to do if things don't work:
                    112: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    113: When things don't work there is usually a few things that commonly
                    114: should be done.
                    115:     1) make includes
                    116:        This should be done automatically by make build.
                    117:     2)  cd share/mk && make install
                    118:        Again, automatically done by make build.
                    119:
                    120: Failsafe rebuild of a small part of the tree:
                    121: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    122: To make sure you rebuild something correctly you want to do
                    123: something like the following:
                    124:     1)  Make sure the includes and .mk files are up to date.
                    125:     2)  Make sure any program used to build the particular
                    126:        utility is up to date.  (yacc, lex, etc...)
                    127:     3)  cd ...path/to/util...
                    128:        make cleandir
                    129:        rm ...all obj directories...
                    130:        make cleandir                   # yes, again
                    131:        make obj
                    132:        make depend && make
                    133:
                    134: Failsafe rebuild of the entire tree:
                    135: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    136: If you really want to make sure the source tree is clean and
1.2       mrg       137: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    138: (a make(1) Makefile) in this manner is not right, and will not work
                    139: for anyone who uses any make(1) features in /etc/mk.conf.
