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  (For building from out-of-date systems or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
                     37:                     build of an updated source tree.
                     39:      build.sh       Bourne-compatible shell script used for building the host

                     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.

                     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

                     96:                        such as ksh88, but not ksh93), or /usr/local/bin/bash.
