                      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 toolchain is enabled on i386.  This new build method
1.38    ! tron       13:        is intended to make all the upgrade issues elsewhere in UPDATING
1.36      tv         14:        obsolete (stay tuned...).
                     15:
1.37      kristerw   16:        i386 platform builds must now set TOOLDIR in mk.conf or the
1.36      tv         17:        environment in order to build the system.  This is a pathname
                     18:        where host build tools will be installed, and must NOT be
                     19:        the same as src/tools.
                     20:
                     21:        (Optionally, USETOOLS=no can be set in the environment if you
                     22:        wish to avoid using the separate host toolchain for building a
                     23:        subtree.  Otherwise, this will default to "yes" automatically.)

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

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

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

                     46:        this will be unable to read symbol tables provided by newer
                     47:        bootloaders.

1.28      assar      51:        build the included texinfo files, do:
                     52:

                     58:        Enabled correct .init/.fini processing in crt0.  The way this
                     59:        was done was to change a -I directive to cc(1), which means
                     60:        make(1) will have a stale dependency (it will be checking the
                     61:        timestamp on the wrong "dot_init.h").
                     62:
                     63:        The symptom you will see is that new programs die with SIGSEGV
                     64:        if you have a stale dependency.
                     65:

                     67:        before starting your build.

                     71:        A construct was added to uvm_page.h that uncovered a bug
                     72:        in lint(1).  If you get a warning/error about a non-portable

                    141: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2       mrg       142:     Build a new kernel first:
                    143:        This makes sure that any new system calls or features
                    144:           expected by the new userland will be present.  This
                    145:           helps to avoid critical errors when upgrading.
1.1       abs       146:     Use object directories:
                    147:        This helps to keep stale object

                    150:           a build.  It's also necessary if you want to use the
                    151:           same source tree for multiple machines.
                    152:           To use object directories:

1.2       mrg       154:            b) Add "OBJMACHINE=yes" to /etc/mk.conf

1.1       abs       159:     Build to a DESTDIR:
                    160:        This helps to keep old
                    161:           installed files (especially libraries) from interfering
                    162:           with the new build.
                    163:           To build to a DESTDIR, set the DESTDIR environment
1.2       mrg       164:           variable before running make build.  It should be set to
