1.123     jmc         3: This file (UPDATING) is intended to be a brief reference to recent
                      4: changes that might cause problems in the build process, and a guide for
                      5: what to do if something doesn't work.
1.1       abs         6:
1.123     jmc         7: For a more detailed description of the recommended way to build NetBSD
                      8: using build.sh, see the BUILDING file.

                     10: Note that much of the advice in this UPDATING file was written before
                     11: build.sh existed.  Nevertheless, the advice here may be useful for
                     12: working around specific problems with build.sh.

                     20:        The way OS emulations lookup filenames inside the emulation root
                     21:        has been changed.  Rather than modify the pathname (and copy back
                     22:        to userspace) namei() and lookup() directly check the emulation
                     23:        root. One side effect is that absolute symlinks inside the emulated
                     24:        root filesytem will be relative to that filesystem - unless they
                     25:        start /../ this is useful when the emulated root is a real install
                     26:        that has such links.
                     27:        This might affect symlinks that have been added to reference outside
                     28:        the emulated root.

                     32:        instead. See the GENERIC32_IP3x kernel configuration for an
                     33:        example.

                     37:         on many platforms due to incorrect flags settings.  If you
                     38:         updated and built after about 20070315, do "nbmake-$arch
                     39:        cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
                     40:        rebuild of object files that might have been built
                     41:        incorrectly, and ensure that you have at least
                     42:        src/lib/libc/Makefile 1.130.

                     51:         The threading model was changed when the newlock2 branch
                     52:         was merged to NetBSD-current.  If you boot with a new
                     53:         kernel (version 4.99.10), then you also need a new pthread
                     54:         library (/usr/lib/libpthread.so.0.7).  If you boot with
                     55:         an old kernel, then you need the old pthread library
                     56:         (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
                     57:         the pthread library in sync, old threaded applications should
                     58:         continue to work with an old or new kernel.  Note that named(8)
                     59:        is the only threaded application in the base system.

                     74:        changed to indicate that our libc has ssp support built-in and
                     75:        does not depend on -lssp and -lssp-nonshared. You'll need to
                     76:        make clean in src/tools/gcc first to rebuild the compiler.

                     84:        withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
                     85:        kernel configuration for an example.  X servers from the last

                     89:        MPACPI is no more. We always configure PCI interrupts using ACPI
                     90:        if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
                     91:        to ACPI_SCANPCI. Thanks to work from fvdl.

                     95:        For userlands with the old version of socket(2), make sure that
                     96:        your kernel has 'options COMPAT_30' set, or else 'bad system call'
                     97:        errors will result.

1.1       abs        99: Hints for a more successful build:
                    100: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123     jmc       101:     Use build.sh, but do not use its "expert mode":
1.132     jmmv      102:        This will automatically build the tools in the
1.123     jmc       103:           correct order, and it will keep the tools and the
                    104:           new build products from interfering with the running
                    105:           system.  This will allow you to ignore most of the
                    106:           other advice in this file.
1.2       mrg       107:     Build a new kernel first:
                    108:        This makes sure that any new system calls or features
                    109:           expected by the new userland will be present.  This
                    110:           helps to avoid critical errors when upgrading.
1.1       abs       111:     Use object directories:
                    112:        This helps to keep stale object
                    113:           files from polluting the build if a Makefile "forgets"
                    114:           about one.  It also makes it easier to clean up after
                    115:           a build.  It's also necessary if you want to use the
                    116:           same source tree for multiple machines.
1.123     jmc       117:           To use object directories with build.sh:
                    118:            a) invoke build.sh with the "-M" or "-O" options.
                    119:           To use object directories without using build.sh:
1.1       abs       120:            a) cd /usr/src ; make cleandir
1.2       mrg       121:            b) Add "OBJMACHINE=yes" to /etc/mk.conf
                    122:            c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1       abs       123:            d) cd /usr/src ; make build
1.2       mrg       124:           Note that running "make obj" in a directory will create
                    125:           in obj.$MACHINE directory.
1.1       abs       126:     Build to a DESTDIR:
1.123     jmc       127:        This helps to keep old installed files (especially libraries)
                    128:           from interfering with the new build.
                    129:           To build to a DESTDIR with build.sh, use the "-D" option.
                    130:           To build to a DESTDIR without using build.sh, set the DESTDIR
                    131:           environment variable before running make build.  It should be
                    132:           set to the pathname of an initially empty directory.
                    133:           Problems: if you do not use build.sh, you might need to
                    134:                update critical utilities without using DESTDIR since
                    135:                nothing is executed from what is installed in DESTDIR.
                    136:                (See critical utils, below.)
1.1       abs       137:     Build often:
                    138:        This keeps critical utilities current enough to not choke
                    139:        on any other part of the source tree that depends on up to
1.123     jmc       140:        date functionality.  If you use build.sh, you should not have
                    141:        this problem.
1.1       abs       142:
                    143: What to do if things don't work:
                    144: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    145: When things don't work there is usually a few things that commonly
                    146: should be done.
                    147:     1) make includes
                    148:        This should be done automatically by make build.
                    149:     2)  cd share/mk && make install
                    150:        Again, automatically done by make build.

                    153: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    154: To make sure you rebuild something correctly you want to do
                    155: something like the following:
                    156:     1)  Make sure the includes and .mk files are up to date.
                    157:     2)  Make sure any program used to build the particular
                    158:        utility is up to date.  (yacc, lex, etc...)
                    159:     3)  cd ...path/to/util...
                    160:        make cleandir
                    161:        rm ...all obj directories...
                    162:        make cleandir                   # yes, again

1.2       mrg       169: ready for a build try the following.  Note that sourcing /etc/mk.conf
