                      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.

                     12:        grep.info is now built from grep.texi using makeinfo.  Since it
                     13:        requires makeinfo v4.0, you need to install new texinfo before
                     14:        building gnu/usr.bin/grep.  To install new texinfo, please follow
                     15:        the instruction described in 20010726 entry.

                     17: 20010803:
                     18:        (i386 only): i386 kernel now uses new instructions like fxsave which
                     19:        old gas doesn't understand.  To build the kernel successfuly, you
                     20:        need to build and install new gas (gnu/usr.bin/gas.new).

                     23:        Bootloader update on ELF platforms.  DDB in kernels from before
                     24:        this will be unable to read symbol tables provided by newer
                     25:        bootloaders.

                     28:        Texinfo was updated to 4.0.  To avoid failures when trying to
1.28      assar      29:        build the included texinfo files, do:
                     30:

                     35:
                     36:        Enabled correct .init/.fini processing in crt0.  The way this
                     37:        was done was to change a -I directive to cc(1), which means
                     38:        make(1) will have a stale dependency (it will be checking the
                     39:        timestamp on the wrong "dot_init.h").
                     40:
                     41:        The symptom you will see is that new programs die with SIGSEGV
                     42:        if you have a stale dependency.
                     43:
                     44:        Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
                     45:        before starting your build.

                     48:
                     49:        A construct was added to uvm_page.h that uncovered a bug
                     50:        in lint(1).  If you get a warning/error about a non-portable
                     51:        bitfield, update your lint(1) before proceeding.

1.21      jmc        56:        will break as mtree aborts early.
                     57:

                     67:

                     71:        get/setprogname() added. Any hostprog's that may use this will need
1.20      jmc        72:         to be bootstrapped manually until the host system is current.
1.18      jmc        73:

                     85: 20010114:
                     86:        introduce .if commands(target) in make(1). You need to
                     87:        bring everything up-to-date first, then without installing
1.23      tron       88:        anything make and install in usr.bin/make, then proceed
1.10      christos   89:        with make build.

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

1.6       ad        103:        major and minor numbers haven't changed, you should update your /dev

1.4       itojun    106: 20000929:
                    107:        The following make directives are obsoleted.
                    108:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                    109:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz       110:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun    111:        additional library libcrypto_{idea,rc5}.
                    112:
1.1       abs       113: 20000623:
                    114:        MKCRYPTO and friends added to share/mk/bsd.own.mk.
                    115:        'cd share/mk ; make install' needed before make build.

                    118: Hints for a more successful build:
                    119: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg       120:     Build a new kernel first:
                    121:        This makes sure that any new system calls or features
                    122:           expected by the new userland will be present.  This
                    123:           helps to avoid critical errors when upgrading.
1.1       abs       124:     Use object directories:
                    125:        This helps to keep stale object
                    126:           files from polluting the build if a Makefile "forgets"
                    127:           about one.  It also makes it easier to clean up after
                    128:           a build.  It's also necessary if you want to use the
                    129:           same source tree for multiple machines.
                    130:           To use object directories:
                    131:            a) cd /usr/src ; make cleandir
1.2       mrg       132:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    133:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs       134:            d) cd /usr/src ; make build
1.2       mrg       135:           Note that running "make obj" in a directory will create
                    136:           in obj.$MACHINE directory.
1.1       abs       137:     Build to a DESTDIR:
                    138:        This helps to keep old
                    139:           installed files (especially libraries) from interfering
                    140:           with the new build.
                    141:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       142:           variable before running make build.  It should be set to
                    143:           the pathname of an initially empty directory.
1.1       abs       144:           Problems: you might need to update critical utilities
                    145:                without using DESTDIR since nothing is executed
                    146:                from what is installed in DESTDIR.
                    147:                (See critical utils, below)
                    148:     Build often:
                    149:        This keeps critical utilities current enough to not choke
                    150:        on any other part of the source tree that depends on up to
                    151:        date functionality.
                    152:
                    153: What to do if things don't work:
                    154: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    155: When things don't work there is usually a few things that commonly
                    156: should be done.
                    157:     1) make includes
                    158:        This should be done automatically by make build.
                    159:     2)  cd share/mk && make install
                    160:        Again, automatically done by make build.

                    164: To make sure you rebuild something correctly you want to do
                    165: something like the following:
                    166:     1)  Make sure the includes and .mk files are up to date.
                    167:     2)  Make sure any program used to build the particular
                    168:        utility is up to date.  (yacc, lex, etc...)
                    169:     3)  cd ...path/to/util...

1.2       mrg       179: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    180: (a make(1) Makefile) in this manner is not right, and will not work
