8 # Build-time functionality
9 # ========================
11 # The USE variable is used to enable optional build-time functionality. For
12 # example, quite a few packages have optional X, gtk or GNOME functionality
13 # that can only be enabled or disabled at compile-time. Gentoo Linux has a
14 # very extensive set of USE variables described in our USE variable HOWTO at
15 # http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1
17 # The available list of use flags with descriptions is in your portage tree.
18 # Use 'less' to view them: --> less /usr/portage/profiles/use.desc <--
20 # 'ufed' is an ncurses/dialog interface available in portage to make handling
21 # useflags for you. 'emerge app-portage/ufed'

26 # Host and optimization settings
27 # ==============================
29 # For optimal performance, enable a CFLAGS setting appropriate for your CPU.
31 # Please note that if you experience strange issues with a package, it may be
32 # due to gcc's optimizations interacting in a strange way. Please test the
33 # package (and in some cases the libraries it uses) at default optimizations
34 # before reporting errors to developers.
36 # Please refer to the GCC manual for a list of possible values.
40 # If you set a CFLAGS above, then this line will set your default C++ flags to
47 # Gentoo is using a new masking system to allow for easier stability testing
48 # on packages. KEYWORDS are used in ebuilds to mask and unmask packages based
49 # on the platform they are set for. A special form has been added that
50 # indicates packages and revisions that are expected to work, but have not yet
51 # been approved for the stable set. '~arch' is a superset of 'arch' which
52 # includes the unstable, in testing, packages. Users of the 'x86' architecture
53 # would add '~x86' to ACCEPT_KEYWORDS to enable unstable/testing packages.
54 # '~ppc', '~sparc' are the unstable KEYWORDS for their respective platforms.
56 # Please note that this is not for development, alpha, beta, nor cvs release
57 # packages. "Broken" packages will not be added to testing and should not be
58 # requested to be added. Alternative routes are available to developers
59 # for experimental packages, and it is at their discretion to use them.
61 # DO NOT PUT ANYTHING BUT YOUR SPECIFIC ~ARCHITECTURE IN THE LIST.
62 # IF YOU ARE UNSURE OF YOUR ARCH, OR THE IMPLICATIONS, DO NOT MODIFY THIS.

149 # Portage uses PORTAGE_BINHOST to specify mirrors for prebuilt-binary packages.
150 # The list is a single entry specifying the full address of the directory
151 # serving the tbz2's for your system. Running emerge with either '--getbinpkg'
152 # or '--getbinpkgonly' will cause portage to retrieve the metadata from all
153 # packages in the directory specified, and use that data to determine what will
154 # be downloaded and merged. '-g' or '-gK' are the recommend parameters. Please
155 # consult the man pages and 'emerge --help' for more information. For FTP, the

164 # Synchronizing Portage
165 # =====================
167 # Each of these settings affects how Gentoo synchronizes your Portage tree.
168 # Synchronization is handled by rsync and these settings allow some control
169 # over how it is done.
171 # SYNC is the server used by rsync to retrieve a localized rsync mirror
172 # rotation. This allows you to select servers that are geographically
173 # close to you, yet still distribute the load over a number of servers.
174 # Please do not single out specific rsync mirrors. Doing so places undue
175 # stress on particular mirrors. Instead you may use one of the following
176 # continent specific rotations:
178 # Default: "rsync://rsync.gentoo.org/gentoo-portage"
179 # North America: "rsync://rsync.namerica.gentoo.org/gentoo-portage"
180 # South America: "rsync://rsync.samerica.gentoo.org/gentoo-portage"
181 # Europe: "rsync://rsync.europe.gentoo.org/gentoo-portage"
182 # Asia: "rsync://rsync.asia.gentoo.org/gentoo-portage"
183 # Australia: "rsync://rsync.au.gentoo.org/gentoo-portage"
185 # If you have multiple Gentoo boxes, it is probably a good idea to have only
186 # one of them sync from the rotations above. The other boxes can then rsync
187 # from the local rsync server, reducing the load on the mirrors.
188 # Instructions for setting up a local rsync server are available here:
189 # http://www.gentoo.org/doc/en/rsync.xml
191 #SYNC="rsync://rsync.gentoo.org/gentoo-portage"
193 # PORTAGE_RSYNC_RETRIES sets the number of times portage will attempt to retrieve
194 # a current portage tree before it exits with an error. This allows
195 # for a more successful retrieval without user intervention most times.
196 #PORTAGE_RSYNC_RETRIES="3"
198 # PORTAGE_RSYNC_EXTRA_OPTS can be used to feed additional options to the rsync
199 # command used by `emerge --sync`. This will not change the default options
200 # which are set by PORTAGE_RSYNC_OPTS (don't change those unless you know
201 # exactly what you're doing).
202 #PORTAGE_RSYNC_EXTRA_OPTS=""
207 # EMERGE_DEFAULT_OPTS allows emerge to act as if certain options are
208 # specified on every run. Useful options include --ask, --verbose,
209 # --usepkg and many others. Options that are not useful, such as --help,
211 #EMERGE_DEFAULT_OPTS=""
213 # INSTALL_MASK allows certain files to not be installed into your file system.
214 # This is useful when you wish to filter out a certain set of files from
215 # ever being installed, such as INSTALL.gz or TODO.gz
218 # MAKEOPTS provides extra options that may be passed to 'make' when a
219 # program is compiled. Presently the only use is for specifying
220 # the number of parallel makes (-j) to perform. The suggested number
221 # for parallel makes is CPUs+1.
224 # PORTAGE_NICENESS provides a default increment to emerge's niceness level.
225 # Note: This is an increment. Running emerge in a niced environment will
226 # reduce it further. Default is unset.
229 # AUTOCLEAN enables portage to automatically clean out older or overlapping
230 # packages from the system after every successful merge. This is the
231 # same as running 'emerge -c' after every merge. Set with: "yes" or "no".
232 # This does not affect the unpacked source. See 'noclean' below.
234 # Warning: AUTOCLEAN="no" can cause serious problems due to overlapping
235 # packages. Do not use it unless absolutely necessary!
238 # PORTAGE_TMPFS is a location where portage may create temporary files.
239 # If specified, portage will use this directory whenever possible
240 # for all rapid operations such as lockfiles and transient data.
241 # It is _highly_ recommended that this be a tmpfs or ramdisk. Do not
242 # set this to anything that does not give a significant performance
243 # enhancement and proper FS compliance for locks and read/write.
244 # /dev/shm is a glibc mandated tmpfs, and should be a reasonable
245 # setting for all linux kernel+glibc based systems.
246 #PORTAGE_TMPFS="/dev/shm"
248 # FEATURES are settings that affect the functionality of portage. Most of
249 # these settings are for developer use, but some are available to non-
250 # developers as well.
252 # 'buildpkg' causes binary packages to be created of all packages that
254 # 'buildsyspkg' only build binary packages for system packages.
255 # 'ccache' enable support for the dev-util/ccache package, which can
256 # noticably decrease the time needed to remerge previously built
258 # 'collision-protect'
259 # prevents packages from overwriting files that are owned by
260 # another package or by no package at all.
261 # 'distcc' enables distcc support via CC.
262 # 'distlocks' enables distfiles locking using fcntl or hardlinks. This
263 # is enabled by default. Tools exist to help clean the locks
264 # after crashes: /usr/lib/portage/bin/clean_locks.
266 # Install source code into /usr/src/debug/${CATEGORY}/${PF}
267 # (also see 'splitdebug'). This feature works only if debugedit
268 # is installed and CFLAGS is set to include debug information
269 # (such as with the -ggdb flag).
270 # 'test' causes ebuilds to perform testing phases if they are capable
271 # of it. Some packages support this automatically via makefiles.
272 # 'metadata-transfer'
273 # automatically perform a metadata transfer when `emerge --sync`
275 # 'noauto' causes ebuild to perform only the action requested and
276 # not any other required actions like clean or unpack -- for
277 # debugging purposes only.
278 # 'nostrip' prevents the stripping of binaries.
279 # 'notitles' disables xterm titlebar updates (which contain status info).
281 # do fetching in parallel to compilation
282 # 'sandbox' enables sandboxing when running emerge and ebuild.
283 # 'splitdebug' Prior to stripping ELF etdyn and etexec files, the debugging
284 # info is stored for later use by various debuggers. This
285 # feature is disabled by 'nostrip'. For installation of source
286 # code, see 'installsources'.
287 # 'strict' causes portage to react strongly to conditions that are
288 # potentially dangerous, like missing/incorrect Manifest files.
289 # 'stricter' causes portage to react strongly to conditions that may
290 # conflict with system security provisions (for example
291 # textrels, executable stacks).
292 # 'userfetch' when portage is run as root, drop privileges to
293 # portage:portage during the fetching of package sources.
294 # 'userpriv' allows portage to drop root privileges while it is compiling,
295 # as a security measure. As a side effect this can remove
296 # sandbox access violations for users.
297 # 'usersandbox' enables sandboxing while portage is running under userpriv.
298 #FEATURES="sandbox buildpkg ccache distcc userpriv usersandbox notitles noauto"

301 # CCACHE_SIZE and CCACHE_DIR are used to control the behavior of ccache, and
302 # and are only used if "ccache" is in FEATURES.
304 # CCACHE_SIZE sets the space limitations for ccache. The default size is
305 # "2G", or 2 gigabytes. Units are specified with 'G', 'M', or 'K'.
309 # CCACHE_DIR sets the ccache path. If not specified, portage will default
310 # to "${PORTAGE_TMPDIR}/ccache".

325 # Warning: commenting this will disable elog
326 PORTAGE_ELOG_CLASSES="warn error log"
328 # PORTAGE_ELOG_SYSTEM: selects the module(s) to process the log messages. Modules
329 # included in portage are (empty means logging is disabled):
330 # echo (display messages again when emerge exits)
331 # save (saves one log per package in $PORT_LOGDIR/elog,
332 # /var/log/portage/elog if $PORT_LOGDIR is unset)
333 # custom (passes all messages to $PORTAGE_ELOG_COMMAND)
334 # syslog (sends all messages to syslog)
335 # mail (send all messages to the mailserver defined
336 # in $PORTAGE_ELOG_MAILURI)
337 # save_summary (like "save" but merges all messages
338 # in $PORT_LOGDIR/elog/summary.log,
339 # /var/log/portage/elog/summary.log if
340 # $PORT_LOGDIR is unset)
341 # mail_summary (like "mail" but sends all messages in
342 # a single mail when emerge exits)
343 # To use elog you should enable at least one module

347 # PORTAGE_ELOG_SYSTEM="mail:warn,error syslog:* save")
348 #PORTAGE_ELOG_SYSTEM="save mail"
350 # PORTAGE_ELOG_COMMAND: only used with the "custom" logging module. Specifies a command
351 # to process log messages. Two variables are expanded:
352 # ${PACKAGE} - expands to the cpv entry of the processed
353 # package (see $PVR in ebuild(5))
354 # ${LOGFILE} - absolute path to the logfile

356 #PORTAGE_ELOG_COMMAND="/path/to/logprocessor -p '\${PACKAGE}' -f '\${LOGFILE}'"
358 # PORTAGE_ELOG_MAILURI: this variable holds all important settings for the mail
359 # module. In most cases listing the recipient address and
360 # the receiving mailserver should be sufficient, but you can
361 # also use advanced settings like authentication or TLS. The
363 # address [[user:passwd@]mailserver[:port]]
