    8 macports.conf - Configuration file of the MacPorts system
     8variants.conf - Global variant configuration file of the MacPorts system
    12 *macports.conf* is the configuration file used to bootstrap the MacPorts
    13 system. This file is read by the *port* command and determines how it behaves.
    14 Lines beginning with '#' are comments, empty lines are ignored. The format is
    15 that of a simple key/value space or tab separated pair.
     12*variants.conf* is the configuration file used to globally select or deselect
     13certain variants on all ports installed by MacPorts. Changes in this file will
     14affect all ports that are installed after the file was changed.
    17 The file contains entries of the form:
    18 --------
    19 <key> <value>
    20 --------
     16For a description of what variants are and how they work, see
    22 The value of any given key can be referred to by the '$\{<keyname>\}'
    23 abstraction, where '<keyname>' expands to the key in question.
    25 KEYS
     19*variants.conf* is read by the *port* command. In the file, lines beginning with
     20'#' are comments, empty lines are ignored. Each line in the file is a space- or
     21tab-delimited list of zero or more variants, where each variant is either
     22explicitly enabled or disabled using a leading '+' or '-'. In EBNF:
    27 // Set default style for second-level labeled lists in this section
    28 horizontal
    30 The following keys are used by *port* itself:
    32 prefix::
    33     Sets the directory where ports are installed. Any path may be used but those
    34     with spaces and/or non ascii characters should be avoided, as this can break
    35     some ports. This key is often referred to as '$\{prefix\}'.
    36     *Default:*;; /opt/local
    38 portdbpath::
    39     Directory where MacPorts keeps working data such as downloaded sources,
    40     installed ports' receipts and the main registry. The same path restrictions
    41     apply as for '$\{prefix\}'.
    42     *Default:*;; $\{prefix\}/var/macports
    44 portdbformat::
    45     Storage type to use for the MacPorts registry. The preferred format is
    46     "sqlite", with "flat" also available as a legacy format.
    47     *Default:*;; sqlite
    49 applications_dir::
    50     Directory containing Applications installed from ports.
    51     *Default:*;; /Applications/MacPorts
    53 frameworks_dir::
    54     Directory containing Frameworks installed from ports.
    55     *Default:*;; $\{prefix\}/Library/Frameworks
    57 sources_conf::
    58     Location of the sources file. This file enables rsync synchronization of the
    59     default ports tree with the MacPorts rsync server (through the "sync" target
    60     of the port command) and any other local tree(s) you might have.
    61     *Default:*;; $\{prefix\}/etc/macports/sources.conf
    63 variants_conf::
    64     Location of the optional global variants definition file, listing those that
    65     should be used in all installed ports if available.
    66     *Default:*;; $\{prefix\}/etc/macports/variants.conf
    68 buildfromsource::
    69     Controls whether ports are built from source or downloaded as pre-built
    70     archives. Setting to 'always' will never use archives, 'never' will always
    71     try to use an archive and fail if one is not available. 'ifneeded' will try
    72     to fetch an archive and fall back to building from source if that isn't
    73     possible.
    74     *Default:*;; ifneeded
    76 portarchivetype::
    77     Format of archives in which to store port images. This controls both the
    78     type of archive cre- ated locally after building from source, and the type
    79     to request from remote servers. Changing this will not affect the usability
    80     of already installed archives; they can be of any supported type.
    81     *Supported types:*;; tgz, tar, tbz, tbz2, tlz, txz, xar, zip, cpgz, cpio
    82     *Default:*;; tbz2
    84 configureccache::
    85     Use ccache (C/C++ compiler cache). Requires that ccache has been installed.
    86     *Default:*;; no
    88 ccache_dir::
    89     Location where ccache stores its files
    90     *Default:*;; $\{portdbpath\}/build/.ccache
    92 ccache_size::
    93     Maximum size ccache may use. Use 'G', 'M', or 'K' suffix for giga-, mega- or
    94     kilobytes.
    95     *Default:*;; 2G
    97 configuredistcc::
    98     Use distcc (distributed compiler). Requires that distcc has been installed.
    99     *Default:*;; no
    101 configurepipe::
    102     Use pipes rather than intermediate files when compiling C/C++/etc (gcc
    103     -pipe)
    104     *Default:*;; yes
    106 buildnicevalue::
    107     Lowered scheduling priority (0-20) to use for make when building ports
    108     *Default:*;; 0
    110 buildmakejobs::
    111     Number of simultaneous make jobs (commands) to use when building ports. 0 is
    112     a special value meaning "the number of CPU cores or the number of GB of
    113     physical memory plus one, whichever is less."
    114     *Default:*;; 0
    116 portautoclean::
    117     Automatic cleaning of the build directory of a given port after it has been
    118     installed.
    119     *Default:*;; yes
    121 keeplogs::
    122     Keep logs for ports.
    123     *Default:*;; no
    125 build_arch::
    126     The machine architecture to try to build for in normal use.
    127     *Regular architectures include:*;; ppc, i386, ppc64, x86_64
    128     *Default (10.6):*;; x86_64 or i386 depending on hardware
    129     *Default (10.5 and earlier):*;; i386 or ppc depending on hardware
    131 universal_archs::
    132     The machine architectures to use for +universal variant (multiple
    133     architecture entries should be space separated).
    134     *Regular architectures include:*;; ppc, i386, ppc64, x86_64
    135     *Default (10.6):*;; x86_64 i386
    136     *Default (10.5 and earlier):*;; i386 ppc
    138 startupitem_type::
    139     Set the default type of startupitems to be generated, overridable by
    140     Portfiles that explicitly state a startupitem.type key. If set to "default",
    141     then a type will be selected that's appropriate to the OS.
    142     *Supported types:*;; none, SystemStarter, launchd, default, rcNG.
    143     *Default:*;; default
    145 destroot_umask::
    146     Umask value to use during the destrooting of a port.
    147     *Default:*;; 022
    149 rsync_server::
    150     Default rsync server to connect to when running "selfupdate" through the
    151     port com- mand to update your base MacPorts infrastructure. While selfupdate
    152     also syncs the ports tree, it uses the settings from $\{sources_conf\} to do
    153     so.
    154     *Default:*;;
    156 rsync_dir::
    157     Rsync directory from which to pull MacPorts sources from the rsync server.
    158     *Default:*;; release/base/ (which pulls sources for the currently shipping
    159     MacPorts release)
    161 rsync_options::
    162     Default rsync options to use when connecting to the rsync server.
    163     *Default:*;; -rtzv --delete-after
    165 binpath::
    166     Sets the directory search path for locating system executables used by
    167     MacPorts. This variable should contain the paths for locating utilities such
    168     as rsync, tar, cvs and others. Don't change this unless you understand and
    169     accept the consequences.
    170     *Default:*;; $\{prefix\}/bin:$\{prefix\}/sbin:/bin:/sbin:/usr/bin:/usr/sbin
    172 extra_env::
    173     List of extra environment variables MacPorts should keep in the user's
    174     environment when sanitizing it. Changing this is unsupported.
    176 proxy_override_env::
    177     Proxy support. Precedence is: env, macports.conf, System Preferences. That
    178     is, if it's set in the environment, that will be used instead of anything
    179     here or in System Preferences. Setting proxy_override_env to yes will cause
    180     any proxies set here (or in System Preferences if set there but not here) to
    181     override what's in the environment. Note that System Preferences doesn't
    182     have an rsync proxy definition. Also note, on 10.5, sudo will clear many
    183     environment variables including those for proxy support. Equivalent
    184     environment variables: http_proxy, HTTPS_PROXY, FTP_PROXY, RSYNC_PROXY,
    185     NO_PROXY
    186     *Default:*;; yes
    188 proxy_http::
    189     HTTP proxy
    190     *Default:*;; none
    192 proxy_https::
    193     HTTPS proxy
    194     *Default:*;; none
    196 proxy_ftp::
    197     FTP proxy
    198     *Default:*;; none
    200 proxy_rsync::
    201     rsync proxy
    202     *Default:*;; none
    204 proxy_skip::
    205     Hosts not to go through the proxy (comma-separated, applies to HTTP, HTTPS
    206     and FTP, but not rsync).
    207     *Default:*;; none
    209 host_blacklist::
    210     Space separated list of download hosts that should not be used.
    211     *Default:*;; none
    213 preferred_hosts::
    214     Space separated list of download hosts that should be used preferentially.
    215     *Default:*;; none
    217 revupgrade_autorun::
    218     Controls whether the rev-upgrade action will be run automatically after
    219     upgrading ports.
    220     *Default:*;; yes
    222 revupgrade_mode::
    223     Controls the rev-upgrade functionality which checks for broken linking and
    224     can rebuild ports to fix it. 'rebuild' means ports will automatically be
    225     rebuilt when broken linking is detected in their files, while 'report' means
    226     broken files will be scanned for and reported but the ports will not be
    227     rebuilt.
    228     *Default:*;; rebuild
    230 default_compilers::
    231     Default value for configure.compiler. This can be a space-separated list.
    232     Later entries will be used if earlier entries are unavailable or blacklisted
    233     by a port. Setting this is unsupported.
    234     *Default:*;; none (internal list based on Xcode version is normally used)
     24line    = variant, { space, variant }
     25space   = ' ' | '\t'
     26variant = ( '+' | '-' ), name
     28where 'name' is the name of the variant. Variants that are not provided by
     29a port (or no port at all) are silently ignored.
     33The path of the 'variants.conf' file is specified in the *variants_conf* option
     34of man:macports.conf[5]. It defaults to
     35'$\{prefix\}/etc/macports/variants.conf'. There is no user-specific
     36'variants.conf' file, but support for this can be emulated by setting
     37'variants.conf' in the user-specific man:macports.conf[5] file.
    239 $\{prefix\}/etc/macports/macports.conf::
    240     Standard system-wide MacPorts configuration file.
     41To prefer the '+quartz' variant over '+x11', you can add the following line to
     42your variants.conf:
     44-x11 +quartz
     46This will disable all x11 variants and enable the quartz variant, when it
    242 ~/.macports/macports.conf::
    243     User-specific configuration override. This file, if found, will be used
    244     instead of the default file at $\{prefix\}/etc/macports/macports.conf.
     49Similarly, if you want all your ports to support multiple architectures, you can
     50enable the universal variant by default:
