                      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.

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

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

                     28:        this will be unable to read symbol tables provided by newer
                     29:        bootloaders.

1.28      assar      33:        build the included texinfo files, do:

                     40:        Enabled correct .init/.fini processing in crt0.  The way this
                     41:        was done was to change a -I directive to cc(1), which means
                     42:        make(1) will have a stale dependency (it will be checking the
                     43:        timestamp on the wrong "dot_init.h").
                     44:
                     45:        The symptom you will see is that new programs die with SIGSEGV
                     46:        if you have a stale dependency.
                     47:
                     48:        Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
                     49:        before starting your build.

                     52:
                     53:        A construct was added to uvm_page.h that uncovered a bug
                     54:        in lint(1).  If you get a warning/error about a non-portable
                     55:        bitfield, update your lint(1) before proceeding.

                     61:

1.20      jmc        76:         to be bootstrapped manually until the host system is current.

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

1.23      tron       92:        anything make and install in usr.bin/make, then proceed

                    101:        If you get make errors,

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

1.6       ad        107:        major and minor numbers haven't changed, you should update your /dev
                    108:        directory.
1.1       abs       109:
1.4       itojun    110: 20000929:
                    111:        The following make directives are obsoleted.
                    112:        MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
                    113:        By default, RSA is built into libcrypto.  IDEA and RC5 will not be
1.16      wiz       114:        built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build
1.4       itojun    115:        additional library libcrypto_{idea,rc5}.

                    119:        'cd share/mk ; make install' needed before make build.

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

                    157: What to do if things don't work:
                    158: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    159: When things don't work there is usually a few things that commonly
                    160: should be done.
                    161:     1) make includes
                    162:        This should be done automatically by make build.
                    163:     2)  cd share/mk && make install
                    164:        Again, automatically done by make build.

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

1.2       mrg       183: ready for a build try the following.  Note that sourcing /etc/mk.conf
                    184: (a make(1) Makefile) in this manner is not right, and will not work
