                      3: NAME
1.52      jmc         4:      BUILDING -- Procedure for building NetBSD from source code.
1.1       tv          5:
                      6: REQUIREMENTS
                      7:      NetBSD is designed to be buildable on most POSIX-compliant host systems.
                      8:      The basic build procedure is the same whether compiling natively (on the
                      9:      same NetBSD architecture) or cross compiling (on another architecture or
                     10:      OS).
                     12:      This source tree contains a special subtree, ``tools'', which uses the
                     13:      host system to create a build toolchain for the target architecture.  The
                     14:      host system must have at least C and C++ compilers in order to create the
                     15:      toolchain (make is not required); all other tools are created as part of
1.53      reed       16:      the NetBSD build process.  (See the environment variables section below
                     17:      if you need to override or manually select your compilers.)

1.44      lukem      30:      Makefile       The main Makefile for NetBSD; should only be run for

1.1       tv         32:                     NetBSD make(1).  (For building from out-of-date systems or
                     33:                     on a non-native host, see the build.sh shell script.)
                     35:      UPDATING       Special notes for updating from an earlier revision of
                     36:                     NetBSD.  It is important to read this file before every

                     41:                     used for both native and cross builds, and should be used
                     42:                     instead of make(1) for any source tree that is updated and
                     43:                     recompiled regularly.

                     78:      The NetBSD build tree is described in hier(7), and the release layout is
                     79:      described in release(7).

1.8       lukem      82:    Environment variables
                     83:      Several environment variables control the behaviour of NetBSD builds.
1.96      apb        85:      HOST_SH           Path name to a shell available on the host system and
                     86:                        suitable for use during the build.  The NetBSD build
                     87:                        system requires a modern Bourne-like shell with POSIX-
                     88:                        compliant features, and also requires support for the
                     89:                        ``local'' keyword to declare local variables in shell
                     90:                        functions (which is a widely-implemented but non-stan-
                     91:                        dardised feature).
                     93:                        Depending on the host system, a suitable shell may be
                     94:                        /bin/sh, /usr/xpg4/bin/sh, /bin/ksh (provided it is a
                     95:                        variant of ksh that supports the ``local'' keyword,
                     96:                        such as ksh88, but not ksh93), or /usr/local/bin/bash.
                     98:                        Most parts of the build require HOST_SH to be an abso-
                     99:                        lute path; however, build.sh allows it to be a simple
                    100:                        command name, which will be converted to an absolute
                    101:                        path by searching the PATH.
1.58      apb       102:
1.53      reed      103:      HOST_CC           Path name to C compiler used to create the toolchain.
                    105:      HOST_CXX          Path name to C++ compiler used to create the toolchain.
1.70      dholland  107:      MACHINE           Machine type, e.g., ``macppc''.
1.8       lukem     108:
1.70      dholland  109:      MACHINE_ARCH      Machine architecture, e.g., ``powerpc''.
1.8       lukem     110:
                    111:      MAKE              Path name to invoke make(1) as.
1.94      apb       113:      MAKEFLAGS         Flags to invoke make(1) with.  Note that build.sh
                    114:                        ignores the value of MAKEFLAGS passed in the environ-
                    115:                        ment, but allows MAKEFLAGS to be set via the -V option.
1.8       lukem     116:

1.59      apb       118:                        tory.  The value is subjected to variable expansion by
1.73      apb       119:                        make(1).  Typical usage is to set this variable to a
                    120:                        value involving the use of `${.CURDIR:S...}' or
                    121:                        `${.CURDIR:C...}', to derive the value of .OBJDIR from
                    122:                        the value of .CURDIR.  Used only if MAKEOBJDIRPREFIX is
                    123:                        not defined.  MAKEOBJDIR can be provided only in the

1.8       lukem     127:

                    130:                        build.sh will create the ${MAKEOBJDIRPREFIX} directory
                    131:                        if necessary, but if make(1) is used without build.sh,
                    132:                        then rules in <bsd.obj.mk> will abort the build if the
                    133:                        ${MAKEOBJDIRPREFIX} directory does not exist.  If the
                    134:                        value is defined and valid, then ${MAKEOBJDIRPRE-
                    135:                        FIX}/${.CURDIR} is used as the .OBJDIR for the current
                    136:                        directory.  The current directory may be read only.
                    137:                        MAKEOBJDIRPREFIX can be provided only in the environ-
                    138:                        ment or via the -M flag of build.sh; it cannot usefully
                    139:                        be set inside a Makefile, including mk.conf or
