                     21:        was done was to change a -I directive to cc(1), which means
                     22:        make(1) will have a stale dependency (it will be checking the
                     23:        timestamp on the wrong "dot_init.h").

                     26:        if you have a stale dependency.
                     27:

                     33:        A construct was added to uvm_page.h that uncovered a bug
                     34:        in lint(1).  If you get a warning/error about a non-portable
                     35:        bitfield, update your lint(1) before proceeding.

1.23      tron       72:        anything make and install in usr.bin/make, then proceed

                     81:        If you get make errors,

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

1.6       ad         87:        major and minor numbers haven't changed, you should update your /dev

                     93:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        94:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build

                     99:        'cd share/mk ; make install' needed before make build.
                    100:
                    101:
                    102: Hints for a more successful build:
                    103: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg       104:     Build a new kernel first:
                    105:        This makes sure that any new system calls or features
                    106:           expected by the new userland will be present.  This
                    107:           helps to avoid critical errors when upgrading.
1.1       abs       108:     Use object directories:
                    109:        This helps to keep stale object
                    110:           files from polluting the build if a Makefile "forgets"
                    111:           about one.  It also makes it easier to clean up after
                    112:           a build.  It's also necessary if you want to use the
                    113:           same source tree for multiple machines.
                    114:           To use object directories:
                    115:            a) cd /usr/src ; make cleandir
1.2       mrg       116:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    117:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs       118:            d) cd /usr/src ; make build
1.2       mrg       119:           Note that running "make obj" in a directory will create
                    120:           in obj.$MACHINE directory.
1.1       abs       121:     Build to a DESTDIR:
                    122:        This helps to keep old
                    123:           installed files (especially libraries) from interfering
                    124:           with the new build.
                    125:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       126:           variable before running make build.  It should be set to
                    127:           the pathname of an initially empty directory.
1.1       abs       128:           Problems: you might need to update critical utilities
                    129:                without using DESTDIR since nothing is executed
                    130:                from what is installed in DESTDIR.
                    131:                (See critical utils, below)
                    132:     Build often:
                    133:        This keeps critical utilities current enough to not choke
                    134:        on any other part of the source tree that depends on up to
                    135:        date functionality.
                    136:
                    137: What to do if things don't work:
                    138: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    139: When things don't work there is usually a few things that commonly
                    140: should be done.
                    141:     1) make includes
                    142:        This should be done automatically by make build.
                    143:     2)  cd share/mk && make install
                    144:        Again, automatically done by make build.

                    147: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    148: To make sure you rebuild something correctly you want to do
                    149: something like the following:
                    150:     1)  Make sure the includes and .mk files are up to date.
                    151:     2)  Make sure any program used to build the particular
                    152:        utility is up to date.  (yacc, lex, etc...)
                    153:     3)  cd ...path/to/util...
                    154:        make cleandir
                    155:        rm ...all obj directories...
                    156:        make cleandir                   # yes, again

                    161: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    162: If you really want to make sure the source tree is clean and
1.2       mrg       163: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    164: (a make(1) Makefile) in this manner is not right, and will not work

                    228: Fix:   Try the following sequence of commands in the directory in question.
                    229:        make cleandir; rm `make print-objdir`; make cleandir; make obj
                    230:        (If you built the tree without "make obj" in the past, obsolete files
                    231:        may remain.  The command tries to clean everything up)
