For # example, quite a few packages have optional X, gtk or GNOME functionality # that can only be enabled or disabled at compile-time. Gentoo Linux has a # very extensive set of USE variables described in our USE variable HOWTO at # https://wiki.gentoo.org/wiki/Handbook:X86/Working/USE # # The available list of use flags with descriptions is in your portage tree. # Use 'less' to view them: --> less /usr/portage/profiles/use.desc <-- # # 'ufed' is an ncurses/dialog interface available in portage to make handling # useflags for you. 'emerge app-portage/ufed' # # Example: #USE="X gtk gnome -alsa" # Host and optimization settings # ============================== # # For optimal performance, enable a CFLAGS setting appropriate for your CPU. # # Please note that if you experience strange issues with a package, it may be # due to gcc's optimizations interacting in a strange way. Please test the # package (and in some cases the libraries it uses) at default optimizations # before reporting errors to developers. # # If your gcc supports it, you can add -frecord-gcc-switches to all of the # following *FLAGS in order to enable *FLAGS ignorance checking for ebuilds: # CFLAGS, CXXFLAGS, FFLAGS, and FCFLAGS. # Note that this check is only enabled if every one of these variables contains # -frecord-gcc-switches, since otherwise the check could result in false # positive results. # # Please refer to the GCC manual for a list of possible values. # #CFLAGS="-O2 -pipe" # # If you set a CFLAGS above, then this line will set your default C++ flags to # the same settings. #CXXFLAGS="${CFLAGS}" # # If you set a CFLAGS above, then this line will set your default FORTRAN 77 # flags to the same settings. #FFLAGS="${CFLAGS}" # # If you set a FFLAGS above, then this line will set your default FORTRAN # flags to the same settings for modern build systems #FCFLAGS="${FFLAGS}" # Advanced Masking # ================ # # Gentoo is using a new masking system to allow for easier stability testing # on packages. KEYWORDS are used in ebuilds to mask and unmask packages based # on the platform they are set for. A special form has been added that # indicates packages and revisions that are expected to work, but have not yet # been approved for the stable set. '~arch' is a superset of 'arch' which # includes the unstable, in testing, packages. Users of the 'x86' architecture # would add '~x86' to ACCEPT_KEYWORDS to enable unstable/testing packages. # '~ppc', '~sparc' are the unstable KEYWORDS for their respective platforms. # # Please note that this is not for development, alpha, beta, nor cvs release # packages. "Broken" packages will not be added to testing and should not be # requested to be added. Alternative routes are available to developers # for experimental packages, and it is at their discretion to use them. # # DO NOT PUT ANYTHING BUT YOUR SPECIFIC ~ARCHITECTURE IN THE LIST. # IF YOU ARE UNSURE OF YOUR ARCH, OR THE IMPLICATIONS, DO NOT MODIFY THIS. # #ACCEPT_KEYWORDS="~arch" # ACCEPT_LICENSE is used to mask packages based on licensing restrictions. # It may contain both license and group names, where group names are # prefixed with the '@' symbol. License groups are defined in the # license_groups file (see portage(5) man page). In addition to license # and group names, the * and -* wildcard tokens are also supported. # # Accept any license except those in the EULA license group (default). #ACCEPT_LICENSE="* -@EULA" # # Only accept licenses in the FREE license group (i.e. Free Software). #ACCEPT_LICENSE="-* @FREE" # Portage Directories # =================== # # Each of these settings controls an aspect of portage's storage and file # system usage. If you change any of these, be sure it is available when # you try to use portage. *** DO NOT INCLUDE A TRAILING "/" *** # # PORTAGE_TMPDIR is the location portage will use for compilations and # temporary storage of data. This can get VERY large depending upon # the application being installed. #PORTAGE_TMPDIR=/var/tmp # # PORTDIR is the location of the portage tree.

If you change # this, you must update your /etc/portage/make.profile symlink accordingly. # ***Warning*** # Data stored inside PORTDIR is in peril of being overwritten or deleted by # the emerge --sync command. The default value of PORTAGE_RSYNC_OPTS # will protect the default locations of DISTDIR and PKGDIR, but users are # warned that any other locations inside PORTDIR are not necessarily safe # for data storage. #PORTDIR=/usr/portage # # DISTDIR is where all of the source code tarballs will be placed for # emerges. After packages are built, it is safe to remove any and # all files from this directory since they will be automatically # fetched on demand for a given build. If you would like to # selectively prune obsolete files from this directory, see # eclean from the gentoolkit package. Note that locations under # /usr/portage are not necessarily safe for data storage. See the # PORTDIR documentation for more information. #DISTDIR=/usr/portage/distfiles # # PKGDIR is the location of binary packages that you can have created # with '--buildpkg' or '-b' while emerging a package. This can get # up to several hundred megs, or even a few gigs. Note that # locations under /usr/portage are not necessarily safe for data # storage. See the PORTDIR documentation for more information. #PKGDIR=/usr/portage/packages # # PORT_LOGDIR is the location where portage will store all the logs it # creates from each individual merge. They are stored as # ${CATEGORY}:${PF}:YYYYMMDD-HHMMSS.log in the directory specified. # If the directory does not exist, it will be created automatically and # group permissions will be applied to it. If the directory already # exists, portage will not modify it's permissions. #PORT_LOGDIR="" # # PORTDIR_OVERLAY is a directory where local ebuilds may be stored without # concern that they will be deleted by rsync updates.

If you use # another mirror we highly recommend leaving the default mirror at the end of # the list so that portage will fall back to it if the files cannot be found # on your specified mirror. We _HIGHLY_ recommend that you change this setting # to a nearby mirror by merging and using the 'mirrorselect' tool. #GENTOO_MIRRORS=" http://distfiles.gentoo.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" # # Portage uses PORTAGE_BINHOST to specify mirrors for prebuilt-binary packages. # The list is a single entry specifying the full address of the directory # serving the tbz2's for your system. Running emerge with either '--getbinpkg' # or '--getbinpkgonly' will cause portage to retrieve the metadata from all # packages in the directory specified, and use that data to determine what will # be downloaded and merged. '-g' or '-gK' are the recommend parameters. Please # consult the man pages and 'emerge --help' for more information.

This allows you to select servers that are geographically # close to you, yet still distribute the load over a number of servers. # Please do not single out specific rsync mirrors. Doing so places undue # stress on particular mirrors. Instead you may use one of the following # continent specific rotations: # # Default: "rsync://rsync.gentoo.org/gentoo-portage" # North America: "rsync://rsync.namerica.gentoo.org/gentoo-portage" # South America: "rsync://rsync.samerica.gentoo.org/gentoo-portage" # Europe: "rsync://rsync.europe.gentoo.org/gentoo-portage" # Asia: "rsync://rsync.asia.gentoo.org/gentoo-portage" # Australia: "rsync://rsync.au.gentoo.org/gentoo-portage" # # If you have multiple Gentoo boxes, it is probably a good idea to have only # one of them sync from the rotations above. The other boxes can then rsync # from the local rsync server, reducing the load on the mirrors. # Instructions for setting up a local rsync server are available here: # http://www.gentoo.org/doc/en/rsync.xml # #SYNC="rsync://rsync.gentoo.org/gentoo-portage" # # PORTAGE_RSYNC_RETRIES sets the number of times portage will attempt to retrieve # a current portage tree before it exits with an error. This allows # for a more successful retrieval without user intervention most times. # If set to a negative number, then retry until all possible addresses are # exhausted. #PORTAGE_RSYNC_RETRIES="-1" # # PORTAGE_RSYNC_EXTRA_OPTS can be used to feed additional options to the rsync # command used by `emerge --sync`. This will not change the default options # which are set by PORTAGE_RSYNC_OPTS (don't change those unless you know # exactly what you're doing). #PORTAGE_RSYNC_EXTRA_OPTS="" # # Advanced Features # ================= # # EMERGE_DEFAULT_OPTS allows emerge to act as if certain options are # specified on every run. Useful options include --ask, --verbose, # --usepkg and many others. Options that are not useful, such as --help, # are not filtered. #EMERGE_DEFAULT_OPTS="" # # INSTALL_MASK allows certain files to not be installed into your file system. # This is useful when you wish to filter out a certain set of files from # ever being installed, such as INSTALL.gz or TODO.gz #INSTALL_MASK="" # # MAKEOPTS provides extra options that may be passed to 'make' when a # program is compiled.
