    NAME

    
    
    build
    
     - information on how to build the system
    
     
    

    DESCRIPTION

    The sources for the Fx system and its applications are contained in three different directories, normally /usr/src /usr/doc and /usr/ports Directory /usr/src contains the ``base system'' sources, which is loosely defined as the things required to rebuild the system to a useful state. Directory /usr/doc contains the source for the system documentation, excluding the manual pages. Directory /usr/ports contains a tree that provides a consistent interface for building and installing third party applications. For more information about the ports build process, see ports(7).

    The make(1) command is used in each of these directories to build and install the things in that directory. Issuing the make(1) command in any directory or subdirectory of those directories has the same effect as issuing the same command in all subdirectories of that directory. With no target specified, the things in that directory are just built.

    A source tree is allowed to be read-only. As described in make(1), objects are usually built in a separate object directory hierarchy specified by the environment variable MAKEOBJDIRPREFIX or under /usr/obj if variable MAKEOBJDIRPREFIX is not set. For a given source directory, its canonical object directory would be ${MAKEOBJDIRPREFIX}${.CURDIR} if make(1) variable MAKEOBJDIRPREFIX is set, or /usr/obj${.CURDIR} if this variable is not set. Cross-builds set the object directory as described in the documentation for the buildworld target below.

    The build may be controlled by defining make(1) variables described in the Sx ENVIRONMENT section below, and by the variables documented in make.conf5.

    The following list provides the names and actions for the targets supported by the build system:

    clean
    Remove any files created during the build process.
    cleandepend
    Remove the file ${.OBJDIR}/${DEPENDFILE} generated by a prior ``make depend '' step.
    cleandir
    Remove the canonical object directory if it exists, or perform actions equivalent to ``make clean cleandepend '' if it does not. This target will also remove an obj link in ${.CURDIR} if that exists.

    It is advisable to run ``make cleandir '' twice: the first invocation will remove the canonical object directory and the second one will clean up ${.CURDIR}

    depend
    Generate a list of build dependencies in file ${.OBJDIR}/${DEPENDFILE}
    install
    Install the results of the build to the appropriate location in the installation directory hierarchy specified in variable DESTDIR
    obj
    Create the canonical object directory associated with the current directory.
    objlink
    Create a symbolic link to the canonical object directory in ${.CURDIR}
    tags
    Generate a tags file using the program specified in the make(1) variable CTAGS The build system supports ctags(1) and GNU Global

    The other supported targets under directory /usr/src are:

    buildenv
    Spawn an interactive shell with environment variables set up for cross-building the system. The target architecture needs to be specified with make(1) variables TARGET_ARCH and TARGET

    This target is only useful after a complete cross-toolchain including the compiler, linker, assembler, headers and libraries has been built; see the toolchain target below.

    buildworld
    Build everything but the kernel, configure files in etc and release The actual build location prefix used is ${MAKEOBJDIRPREFIX}${.CURDIR} for native builds, and ${MAKEOBJDIRPREFIX}/${TARGET}${.CURDIR} for cross builds and native builds with variable CROSS_BUILD_TESTING set.
    cleanworld
    Attempt to clean up targets built by a preceding buildworld step.
    distributeworld
    Distribute everything compiled by a preceding buildworld step. Files are placed in the directory hierarchy specified by make(1) variable DISTDIR This target is used while building a release; see release(7).
    installworld
    Install everything built by a preceding buildworld step into the directory hierarchy pointed to by make(1) variable DESTDIR

    If installing onto an NFS file system and running make(1) with the -j option, make sure that rpc.lockd8 is running on both client and server. See rc.conf5 on how to make it start at boot time.

    toolchain
    Create the build toolchain needed to build the rest of the system. For cross-architecture builds, this step creates a cross-toolchain.
    universe
    Execute a buildworld and buildkernel for all kernels including LINT for each architecture supported by the build system. This command takes a long time.
    update
    Get updated sources as configured in make.conf5.

    Kernel specific build targets in /usr/src are:

    buildkernel
    Rebuild the kernel and the kernel modules.
    installkernel
    Install the kernel and the kernel modules to directory ${DESTDIR}/boot/kernel renaming any pre-existing directory with this name to kernel.old if it contained the currently running kernel. The target directory under ${DESTDIR} may be modified using the INSTKERNNAME and KODIR make(1) variables.
    kernel
    Equivalent to buildkernel followed by installkernel
    kernel-toolchain
    Rebuild the tools needed for kernel compilation. Use this if you did not do a buildworld first.
    reinstallkernel
    Reinstall the kernel and the kernel modules, overwriting the contents of the target directory. As with the installkernel target, the target directory can be specified using the make(1) variable INSTKERNNAME

    Convenience targets for cleaning up the install destination directory denoted by variable DESTDIR include:

    check-old
    Print a list of old files and directories in the system.
    delete-old
    Delete obsolete base system files and directories interactively. When -DBATCH_DELETE_OLD_FILES is specified at the command line, the delete operation will be non-interactive. The variables DESTDIR TARGET_ARCH and TARGET should be set as with ``make installworld ''
    delete-old-libs
    Delete obsolete base system libraries interactively. This target should only be used if no 3rd party software uses these libraries. When -DBATCH_DELETE_OLD_FILES is specified at the command line, the delete operation will be non-interactive. The variables DESTDIR TARGET_ARCH and TARGET should be set as with ``make installworld ''

     

    ENVIRONMENT

    Variables that influence all builds include:

    DESTDIR
    The directory hierarchy prefix where built objects will be installed. If not set, DESTDIR defaults to the empty string.
    MAKEOBJDIRPREFIX
    Defines the prefix for directory names in the tree of built objects. Defaults to /usr/obj if not defined. This variable should only be set in the environment and not via /etc/make.conf or the command line.
    NO_WERROR
    If defined, compiler warnings will not cause the build to halt, even if the makefile says otherwise.

    Additionally, builds in /usr/src are influenced by the following make(1) variables:

    LOCAL_DIRS
    If set, this variable supplies a list of additional directories to build, relative to the root of the source tree.
    SUBDIR_OVERRIDE
    Override the default list of sub-directories and only build the sub-directory named in this variable. This variable is useful when debugging failed builds.
    make some-target SUBDIR_OVERRIDE=foo/bar
    
    TARGET
    The target hardware platform. This is analogous to the ``uname -m '' output. This is necessary to cross-build some target architectures. For example, cross-building for PC98 machines requires TARGET_ARCH = i386 and TARGET = pc98 If not set, TARGET defaults to the current hardware platform.
    TARGET_ARCH
    The target machine processor architecture. This is analogous to the ``uname -p '' output. Set this to cross-build for a different architecture. If not set, TARGET_ARCH defaults to the current machine architecture.

    Builds under directory /usr/doc are influenced by the following make(1) variables:

    DOC_LANG
    If set, restricts the documentation build to the language subdirectories specified as its content. The default action is to build documentation for all languages.

     

    FILES

    /usr/doc/Makefile
    /usr/doc/share/mk/doc.project.mk
    /usr/ports/Mk/bsd.port.mk
    /usr/ports/Mk/bsd.sites.mk
    /usr/share/examples/etc/make.conf
    /usr/src/Makefile
    /usr/src/Makefile.inc1

     

    EXAMPLES

    For an ``approved'' method of updating your system from the latest sources, please see the Sx COMMON ITEMS section in src/UPDATING

    The following sequence of commands can be used to cross-build the system for the sparc64 architecture on an i386 host:

    cd /usr/src
    make TARGET_ARCH=sparc64 buildworld
    make TARGET_ARCH=sparc64 DESTDIR=/clients/sparc64 installworld
