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

                     25:

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

                    145: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    146: To make sure you rebuild something correctly you want to do
                    147: something like the following:
                    148:     1)  Make sure the includes and .mk files are up to date.
                    149:     2)  Make sure any program used to build the particular
                    150:        utility is up to date.  (yacc, lex, etc...)
                    151:     3)  cd ...path/to/util...

                    159: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    160: If you really want to make sure the source tree is clean and
1.2       mrg       161: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    162: (a make(1) Makefile) in this manner is not right, and will not work
