 STATUS  
      This document is a work-in-progress.  As such, the information described  
      here may not match the reality of the build system as of this writing.  
      Once this document is completely in sync with reality, this paragraph  
      will be removed.  
   
      Discrepancies between this documentation and the current reality of im-  
      plementation are noted specially, as with the note below:  
   
      Note: This document applies only to platforms which use the new toolchain  
      as indicated by the default setting of TOOLCHAIN_MISSING in <bsd.own.mk>.  
      Platforms which have not yet been switched to the new toolchain should  
      continue building traditionally, using the notes specified in the file  
      UPDATING.

            Note: A couple of host toolchain components are not yet available  
            in the tools directory.  Also, some tools use non-POSIX, non-ANSI C  
            extensions and need to be standardized.  As a result, cross-compil-  
            ing from systems other than NetBSD is not currently supported.

    Environment variables     Environment variables
      Several environment variables control the behaviour of NetBSD builds.       Several environment variables control the behaviour of NetBSD builds.
   
      MACHINE           Machine type.       HOST_SH           Path name to a shell available on the host system and
                          suitable for use during the build.  The NetBSD build
                          system requires a modern Bourne-like shell with POSIX-
                          compliant features, and also requires support for the
                          ``local'' keyword to declare local variables in shell
                          functions (which is a widely-implemented but non-stan-
                          dardised feature).
   
                          Depending on the host system, a suitable shell may be
                          /bin/sh, /usr/xpg4/bin/sh, /bin/ksh (provided it is a
                          variant of ksh that supports the ``local'' keyword,
                          such as ksh88, but not ksh93), or /usr/local/bin/bash.
   
                          Most parts of the build require HOST_SH to be an abso-
                          lute path; however, build.sh allows it to be a simple
                          command name, which will be converted to an absolute
                          path by searching the PATH.
   
      MACHINE_ARCH      Machine architecture.       HOST_CC           Path name to C compiler used to create the toolchain.
   
        HOST_CXX          Path name to C++ compiler used to create the toolchain.
   
        MACHINE           Machine type, e.g., ``macppc''.
   
        MACHINE_ARCH      Machine architecture, e.g., ``powerpc''.

                          build.sh will create the ${MAKEOBJDIRPREFIX} directory
                          if necessary, but if make(1) is used without build.sh,
                          then rules in <bsd.obj.mk> will abort the build if the
                          ${MAKEOBJDIRPREFIX} directory does not exist.  If the

                      RELEASEDIR/RELEASEMACHINEDIR/installation/installimage
                      directory.  The installation disk image is suitable for
                      copying to bootable USB flash memory sticks, etc., for
                      machines which are able to boot from such devices.  The
                      file system in the bootable disk image will have a layout
                      as described in release(7).
   
                      The installation image is bootable, and will automatically

                      can be used to install or upgrade a NetBSD system.  The
                      image also contains tools that may be useful in repairing a
                      damaged NetBSD installation.
   
                      Before ``make install-image'' is attempted, RELEASEDIR must
                      be populated by ``make release'' or equivalent.  The build
                      must have been performed with MKUNPRIVED=yes because ``make
                      install-image'' relies on information in DESTDIR/METALOG.
   
        live-image    Create NetBSD live images in the
                      RELEASEDIR/RELEASEMACHINEDIR/installation/liveimage direc-

                      NetBSD up to multi-user mode, including all files which
                      should be extracted during installation, NetBSD disklabel,
                      bootloaders, etc.
   
                      The live image is suitable for use as a disk image in vir-
                      tual machine environments such as QEMU, and also useful to
                      boot NetBSD from a USB flash memory stick on a real
                      machine, without the need for installation.
   
                      Before ``make live-image'' is attempted, RELEASEDIR must be
                      populated by ``make release'' or equivalent.  The build
                      must have been performed with MKUNPRIVED=yes because ``make

        If a host system's default shell does support the required features, then
        we suggest that you explicitly specify a suitable shell using a command
        like
   
              /path/to/suitable/shell build.sh [options]
   
        The above command will usually enable build.sh to automatically set
        HOST_SH=/path/to/suitable/shell, but if that fails, then the following
        set of commands may be used instead:
   
              HOST_SH=/path/to/suitable/shell
              export HOST_SH
              ${HOST_SH} build.sh [options]
   
        If build.sh detects that it is being executed under an unsuitable shell,
        it attempts to exec a suitable shell instead, or prints an error message.
        If HOST_SH is not set explicitly, then build.sh sets a default using
        heuristics dependent on the host platform, or from the shell under which
        build.sh is executed (if that can be determined), or using the first copy
        of sh found in PATH.

                  Note: It is highly recommended that you know what you are doing
                  when you use this option.
   
        -h        Print a help message.
   
        -j njob   Run up to njob make(1) subjobs in parallel; passed through to
                  make(1).  If you see failures for reasons other than running
                  out of memory while using build.sh with -j, please save com-
                  plete build logs so the failures can be analyzed.
   
                  To achieve the fastest builds, -j values between (1 + the num-
                  ber of CPUs) and (2 * the number of CPUs) are recommended.  Use
                  lower values on machines with limited memory or I/O bandwidth.
   
        -M obj    Set MAKEOBJDIRPREFIX to obj.  Unsets MAKEOBJDIR.  See ``-O
                  -obj'' for more information.
   
                  For instance, if the source directory is /usr/src, a setting of
                  ``-M /usr/obj'' will place build-time files under
                  /usr/obj/usr/src/bin, /usr/obj/usr/src/lib,
                  /usr/obj/usr/src/usr.bin, and so forth.
   
                  If a relative path is specified, it will be converted to an
                  absolute path before being used.  build.sh imposes the restric-
                  tion that the argument to the -M option must not begin with a
                  ``$'' (dollar sign) character; otherwise it would be too diffi-
                  cult to determine whether the value is an absolute or a rela-
                  tive path.  If the directory does not already exist, build.sh
                  will create it.
   
        -m mach   Set the value of MACHINE to mach, except in some special cases
                  listed below.  This will also override any value of
                  MACHINE_ARCH in the process environment with a value deduced
                  from mach, unless -a is specified.  All cross builds require
                  -m, but if unset on a NetBSD host, the host's value of MACHINE
                  will be detected and used automatically.
   
                  Some machines support multiple values for MACHINE_ARCH.  The
                  following special cases for the mach argument are defined to
                  set the listed values of MACHINE and MACHINE_ARCH:
   
                        mach          MACHINE    MACHINE_ARCH
                        evbarm        evbarm     (not set)

                        sbmips-el     sbmips     mipsel
   
        -N noiselevel
                  Set the ``noisyness'' level of the build, by setting
                  MAKEVERBOSE to noiselevel.
   
      -n        Show the commands that would be executed by build.sh, but do       -n        Show the commands that would be executed by build.sh, but do

                place the built object files under obj.  For instance, a set-                 place the built object files under obj.  Unsets

                /usr/obj/bin, /usr/obj/lib, and so forth.  
   
      -o        Set the value of MKOBJDIRS to ``no''.  
   
      -R rel    Set the value of RELEASEDIR to rel.                 For instance, a setting of ``-O /usr/obj'' will place build-
                  time files under /usr/obj/bin, /usr/obj/lib, /usr/obj/usr.bin,
                  and so forth.
   
                  If a relative path is specified, it will be converted to an
                  absolute path before being used.  build.sh imposes the restric-
                  tion that the argument to the -O option must not contain a
                  ``$'' (dollar sign) character.  If the directory does not
                  already exist, build.sh will create it.
   
                  In normal use, exactly one of the -M or -O options should be
                  specified.  If neither -M nor -O is specified, then a default
                  object directory will be chosen according to rules in
                  <bsd.obj.mk>.  Relying on this default is not recommended
                  because it is determined by complex rules that are influenced
                  by the values of several variables and by the location of the
                  source directory.
   
        -o        Set the value of MKOBJDIRS to ``no''.  Otherwise, it will be
                  automatically set to ``yes''.  This default is opposite to the
                  behaviour when not using build.sh.
   
        -R rel    Set the value of RELEASEDIR to rel.  If a relative path is
                  specified, it will be converted to an absolute path before
                  being used.
   
      -r        Remove the contents of DESTDIR and TOOLDIR before building       -r        Remove the contents of DESTDIR and TOOLDIR before building

                  ified, it will be converted to an absolute path before being
                  used.  If set, the bootstrap ``make'' will only be rebuilt if
