# 章 13. A Sample `Makefile`

Here is a sample `Makefile` that you can use to create a new port. Make sure you remove all the extra comments (ones between brackets)!

It is recommended that you follow this format (ordering of variables, empty lines between sections, etc.). This format is designed so that the most important information is easy to locate. We recommend that you use portlint to check the `Makefile`.

    [the header...just to make it easier for us to identify the ports.]
    # New ports collection makefile for:   xdvi
    [the "version required" line is only needed when the PORTVERSION
     variable is not specific enough to describe the port.]
    # Date created:                26 May 1995
    [this is the person who did the original port to FreeBSD, in particular, the
    person who wrote the first version of this Makefile.  Remember, this should
    not be changed when upgrading the port later.]
    # Whom:                        Satoshi Asami <asami@FreeBSD.org>
    #
    # $FreeBSD$
    [ ^^^^^^^^^ This will be automatically replaced with RCS ID string by CVS
    when it is committed to our repository.  If upgrading a port, do not alter
    this line back to "$FreeBSD$".  CVS deals with it automatically.]
    #

    [section to describe the port itself and the master site - PORTNAME
     and PORTVERSION are always first, followed by CATEGORIES,
     and then MASTER_SITES, which can be followed by MASTER_SITE_SUBDIR.
     PKGNAMEPREFIX and PKGNAMESUFFIX, if needed, will be after that.
     Then comes DISTNAME, EXTRACT_SUFX and/or DISTFILES, and then
     EXTRACT_ONLY, as necessary.]
    PORTNAME=      xdvi
    PORTVERSION=   18.2
    CATEGORIES=    print
    [do not forget the trailing slash ("/")!
     if you are not using MASTER_SITE_* macros]
    MASTER_SITES=  ${MASTER_SITE_XCONTRIB}
    MASTER_SITE_SUBDIR= applications
    PKGNAMEPREFIX= ja-
    DISTNAME=      xdvi-pl18
    [set this if the source is not in the standard ".tar.gz" form]
    EXTRACT_SUFX=  .tar.Z

    [section for distributed patches -- can be empty]
    PATCH_SITES=   ftp://ftp.sra.co.jp/pub/X11/japanese/
    PATCHFILES=    xdvi-18.patch1.gz xdvi-18.patch2.gz

    [maintainer; *mandatory*!  This is the person who is volunteering to
     handle port updates, build breakages, and to whom a users can direct
     questions and bug reports.  To keep the quality of the Ports Collection
     as high as possible, we no longer accept new ports that are assigned to
     "ports@FreeBSD.org".]
    MAINTAINER=    asami@FreeBSD.org
    COMMENT=       A DVI Previewer for the X Window System

    [dependencies -- can be empty]
    RUN_DEPENDS=   gs:${PORTSDIR}/print/ghostscript
    LIB_DEPENDS=   Xpm.5:${PORTSDIR}/graphics/xpm

    [this section is for other standard bsd.port.mk variables that do not
     belong to any of the above]
    [If it asks questions during configure, build, install...]
    IS_INTERACTIVE=        yes
    [If it extracts to a directory other than ${DISTNAME}...]
    WRKSRC=                ${WRKDIR}/xdvi-new
    [If the distributed patches were not made relative to ${WRKSRC}, you
     may need to tweak this]
    PATCH_DIST_STRIP=      -p1
    [If it requires a "configure" script generated by GNU autoconf to be run]
    GNU_CONFIGURE= yes
    [If it requires GNU make, not /usr/bin/make, to build...]
    USE_GMAKE=     yes
    [If it is an X application and requires "xmkmf -a" to be run...]
    USE_IMAKE=     yes
    [et cetera.]

    [non-standard variables to be used in the rules below]
    MY_FAVORITE_RESPONSE=  "yeah, right"

    [then the special rules, in the order they are called]
    pre-fetch:
    	i go fetch something, yeah

    post-patch:
    	i need to do something after patch, great

    pre-install:
    	and then some more stuff before installing, wow

    [and then the epilogue]
    .include <bsd.port.mk>
