                      3: This file is intended to be a brief introduction to the build

1.38      tron       18:        is intended to make all the upgrade issues elsewhere in UPDATING

1.37      kristerw   21:        i386 platform builds must now set TOOLDIR in mk.conf or the
1.36      tv         22:        environment in order to build the system.  This is a pathname
                     23:        where host build tools will be installed, and must NOT be
                     24:        the same as src/tools.

                     27:        wish to avoid using the separate host toolchain for building a
                     28:        subtree.  Otherwise, this will default to "yes" automatically.)

                     32:        a header file, uvm/uvm_vnode.h.  There may be stale .depend

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

                     46:        old gas doesn't understand.  To build the kernel successfuly, you
                     47:        need to build and install new gas (gnu/usr.bin/gas.new).

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

                     77:        in lint(1).  If you get a warning/error about a non-portable

                    146: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg       147:     Build a new kernel first:
                    148:        This makes sure that any new system calls or features
                    149:           expected by the new userland will be present.  This
                    150:           helps to avoid critical errors when upgrading.
1.1       abs       151:     Use object directories:
                    152:        This helps to keep stale object
                    153:           files from polluting the build if a Makefile "forgets"
                    154:           about one.  It also makes it easier to clean up after
                    155:           a build.  It's also necessary if you want to use the
                    156:           same source tree for multiple machines.
                    157:           To use object directories:
                    158:            a) cd /usr/src ; make cleandir
1.2       mrg       159:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    160:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf

1.2       mrg       162:           Note that running "make obj" in a directory will create

1.1       abs       164:     Build to a DESTDIR:
                    165:        This helps to keep old
                    166:           installed files (especially libraries) from interfering
                    167:           with the new build.
                    168:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       169:           variable before running make build.  It should be set to
                    170:           the pathname of an initially empty directory.
1.1       abs       171:           Problems: you might need to update critical utilities
                    172:                without using DESTDIR since nothing is executed
                    173:                from what is installed in DESTDIR.
                    174:                (See critical utils, below)
                    175:     Build often:

                    177:        on any other part of the source tree that depends on up to
                    178:        date functionality.

                    194:     2)  Make sure any program used to build the particular
