                      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:        The new "ubcperf" code committed by Chuck Silvers removed
        !            13:        a header file, uvm/uvm_vnode.h.  There may be stale .depend

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

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

                     32:        this will be unable to read symbol tables provided by newer
                     33:        bootloaders.

1.28      assar      37:        build the included texinfo files, do:

                     44:        Enabled correct .init/.fini processing in crt0.  The way this
                     45:        was done was to change a -I directive to cc(1), which means
                     46:        make(1) will have a stale dependency (it will be checking the
                     47:        timestamp on the wrong "dot_init.h").
                     48:
                     49:        The symptom you will see is that new programs die with SIGSEGV
                     50:        if you have a stale dependency.
                     51:
                     52:        Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
                     53:        before starting your build.

                     56:
                     57:        A construct was added to uvm_page.h that uncovered a bug
                     58:        in lint(1).  If you get a warning/error about a non-portable
                     59:        bitfield, update your lint(1) before proceeding.

1.23      tron       96:        anything make and install in usr.bin/make, then proceed

1.6       ad        111:        major and minor numbers haven't changed, you should update your /dev

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

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

                    163: When things don't work there is usually a few things that commonly
                    164: should be done.
                    165:     1) make includes
                    166:        This should be done automatically by make build.

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