                      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.

                     25:        Enabled correct .init/.fini processing in crt0.  The way this
                     26:        was done was to change a -I directive to cc(1), which means
                     27:        make(1) will have a stale dependency (it will be checking the
                     28:        timestamp on the wrong "dot_init.h").

                     32:
                     33:        Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so

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

1.21      jmc        45:        will break as mtree aborts early.
                     46:

1.23      tron       77:        anything make and install in usr.bin/make, then proceed

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

1.6       ad         92:        major and minor numbers haven't changed, you should update your /dev

                     97:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                     98:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz        99:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun    100:        additional library libcrypto_{idea,rc5}.
                    101:

                    103:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                    104:        'cd share/mk ; make install' needed before make build.
                    105:
                    106:
                    107: Hints for a more successful build:
                    108: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg       109:     Build a new kernel first:
                    110:        This makes sure that any new system calls or features
                    111:           expected by the new userland will be present.  This
                    112:           helps to avoid critical errors when upgrading.
1.1       abs       113:     Use object directories:
                    114:        This helps to keep stale object
                    115:           files from polluting the build if a Makefile "forgets"
                    116:           about one.  It also makes it easier to clean up after
                    117:           a build.  It's also necessary if you want to use the
                    118:           same source tree for multiple machines.
                    119:           To use object directories:
                    120:            a) cd /usr/src ; make cleandir
1.2       mrg       121:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    122:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs       123:            d) cd /usr/src ; make build
1.2       mrg       124:           Note that running "make obj" in a directory will create
                    125:           in obj.$MACHINE directory.
1.1       abs       126:     Build to a DESTDIR:
                    127:        This helps to keep old
                    128:           installed files (especially libraries) from interfering
                    129:           with the new build.
                    130:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       131:           variable before running make build.  It should be set to
                    132:           the pathname of an initially empty directory.
1.1       abs       133:           Problems: you might need to update critical utilities
                    134:                without using DESTDIR since nothing is executed
                    135:                from what is installed in DESTDIR.
                    136:                (See critical utils, below)
                    137:     Build often:
                    138:        This keeps critical utilities current enough to not choke
                    139:        on any other part of the source tree that depends on up to
                    140:        date functionality.
                    141:
                    142: What to do if things don't work:
                    143: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    144: When things don't work there is usually a few things that commonly
                    145: should be done.
                    146:     1) make includes
                    147:        This should be done automatically by make build.
                    148:     2)  cd share/mk && make install
                    149:        Again, automatically done by make build.
                    150:

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

                    166: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    167: If you really want to make sure the source tree is clean and
1.2       mrg       168: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    169: (a make(1) Makefile) in this manner is not right, and will not work
