.TH "MAKE.CONF" "5" "Dec 2005" "Portage 2.1" "portage" .SH "NAME" make.conf \- custom settings for Portage .SH "SYNOPSIS" .B /etc/make.conf .SH "DESCRIPTION" This file contains various variables that are used by Portage. Portage will check the currently\-defined environment variables first for any settings. If no environment settings are found, Portage then checks /etc/make.conf. If no setting is found in /etc/make.conf, Portage checks /etc/make.globals. If no setting is found there, the profile's default setting is grabbed from /etc/make.profile/make.defaults. Please note that all user settings should be made in the environment or in /etc/make.conf, which is intended to be customized by the user. .br Exceptions are incremental variables such as USE, CONFIG_PROTECT*, and ACCEPT_KEYWORDS. Incremental variables are propagated down from make.defaults to make.globals to make.conf to the environment settings. Clearing these variables requires a clear\-all as in: export USE="\-*" .SH "VARIABLES" .TP \fBACCEPT_KEYWORDS\fR = \fI[space delimited list of KEYWORDS]\fR Enable testing of ebuilds that have not yet been deemed 'stable'. Users of the 'x86' architecture would set this to '~x86' while ppc users would set this to '~ppc'. This is an incremental variable. Only define a ~arch. .br Defaults to the value of $ARCH. .TP \fBBUILD_PREFIX\fR = \fI[path]\fR Defines the location of the package working directory. .br Defaults to ${PORTAGE_TMPDIR}/portage .TP .B CBUILD This variable is passed by the \fIebuild scripts\fR to the \fIconfigure\fR as \fI\-\-build=${CBUILD}\fR only if it is defined. Do not set this yourself unless you know what you are doing. .TP \fBCCACHE_DIR\fR = \fI[path]\fR Defines the location of the ccache working directory. See the \fBccache\fR(1) man page for more information. .br Defaults to /var/tmp/ccache .TP \fBCCACHE_SIZE\fR = \fI"size"\fR This controls the space use limitations for ccache. The default is 2 gigabytes ('2G'). Sizes are specified with 'G', 'M', or 'K'. .TP .B CFLAGS CXXFLAGS Use these variables to set the desired optimization/CPU instruction settings for applications that you compile. Nearly all ebuild files will take advantage of your custom settings, resulting in a Gentoo Linux that is fully customized to your specifications. Please use sane settings as some packages will fail to compile/run if the optimizations are too extreme. For more information, see the \fIInvoking GCC\fR section of the gcc manual: .br http://gcc.gnu.org/onlinedocs/ .TP .B CHOST This variable is passed by the \fIebuild scripts\fR to the \fIconfigure\fR step as \fI\-\-host=${CHOST}\fR. This way you can force the build\-host. For more information: .br http://gcc.gnu.org/onlinedocs/gcc\-3.2/gcc/Submodel\-Options.html .br http://gcc.gnu.org/onlinedocs/gcc\-3.3/gcc/Submodel\-Options.html .br http://gcc.gnu.org/onlinedocs/gcc\-2.95.3/gcc_2.html .TP \fBCLEAN_DELAY\fR = \fIinteger\fR Determines how long the countdown delay will be after running `emerge clean`. .br Defaults to 5 seconds. .TP \fBCOLLISION_IGNORE\fR = \fI[space delimited list of files and/or directories]\fR This variable allows the user to disable \fIcollision\-protect\fR for specific files and/or directories. .TP \fBCONFIG_PROTECT\fR = \fI[space delimited list of files and/or directories]\fR All files and/or directories that are defined here will have "config file protection" enabled for them. For more information, please see `emerge \-\-help config`. .TP \fBCONFIG_PROTECT_MASK\fR = \fI[space delimited list of files and/or directories]\fR All files and/or directories that are defined here will have "config file protection" disabled for them. For more information, please see `emerge \-\-help config`. .TP .B CTARGET This variable is passed by the \fIebuild scripts\fR to the \fIconfigure\fR as \fI\-\-target=${CTARGET}\fR only if it is defined. .TP \fBDISTDIR\fR = \fI[path]\fR Defines the location of your local source file repository. .br Defaults to ${PORTDIR}/distfiles. .TP .B EBEEP_IGNORE Defines whether or not to ignore audible beeps when displaying important informational messages. This variable is unset by default. .TP .B EMERGE_DEFAULT_OPTS Options to append to the end of the \fBemerge\fR(1) command line on every invocation. These options will not be appended to the command line if --ignore-default-opts is specified. .TP .B EPAUSE_IGNORE Defines whether or not to ignore short pauses that occur when displaying important informational messages. This variable is unset by default. .TP \fBFEATURES\fR = \fI"sandbox ccache"\fR Defines actions portage takes by default. These options should not be changed by anyone but developers and/or maintainers. 'sandbox' is an important part of \fBFEATURES\fR and should not be disabled by default. This is an incremental variable. .RS .TP .B assume-digests When commiting work to cvs with \fBrepoman\fR(1), assume that all existing SRC_URI digests are correct. This feature also affects digest generation via \fBebuild\fR(1) and \fBemerge\fR(1) (emerge generates digests only when the \fIdigest\fR feature is enabled). .TP .B buildpkg Binary packages will be created for all packages that are merged. .TP .B buildsyspkg Build binary packages for just packages in the system set. .TP .B ccache Enable portage support for the ccache package. If the ccache dir is not present in the user's environment, then portage will default to ${PORTAGE_TMPDIR}/ccache (with \fIuserpriv\fR) and to /root/.ccache otherwise. .TP .B confcache Enable confcache support; global configure caching, speeds up autotool based configure calls via the econf helper function. See \fBebuild\fR(5) for more information. .TP .B collision\-protect A QA\-feature to ensure that a package doesn't overwrite files it doesn't own. The \fICOLLISION_IGNORE\fR variable can be used to selectively disable this feature. .TP .B cvs A feature for developers that causes portage to enable all USE flags in SRC_URI when creating digests. .TP .B digest Autogenerate digests for packages when running the \fBemerge\fR(1) command. If the \fIassume-digests\fR feature is also enabled then existing SRC_URI digests will be reused whenever they are available. .TP .B distcc Enable portage support for the distcc package. .TP .B distlocks Portage uses lockfiles to ensure competing instances don't clobber each other's files. This feature is enabled by default but may cause heartache on less intelligent remote filesystems like NFSv2 and some strangely configured Samba server (oplocks off, NFS re\-export). A tool /usr/lib/portage/bin/clean_locks exists to help handle lock issues when a problem arises (normally due to a crash or disconnect). .TP .B fixpackages Runs the script that will fix the dependencies in all binary packages. This is run whenever packages are moved around in the portage tree. Please note that this can take a lot of time. .TP .B getbinpkg Force emerges to always try to fetch files from the \fIPORTAGE_BINHOST\fR. See \fBmake.conf\fR(5) for more information. .TP .B gpg Check the signatures of Manifests and make sure they are correct. .TP .B installsources Install source code into /usr/src/debug/${CATEGORY}/${PF} (also see \fBsplitdebug\fR). This feature works only if debugedit is installed. .TP .B keeptemp Do not delete the ${T} directory after the merge process. .TP .B keepwork Do not delete the ${WORKDIR} directory after the merge process. .TP .B metadata-transfer Automatically perform a metadata transfer when `emerge --sync` is run. .TP .B mirror This will cause \fBFETCHCOMMAND\fR to always be run even if the file already exists in \fBDISTDIR\fR. .TP .B noauto When utilizing \fBebuild\fR(1), only run the function requested. .TP .B noclean Do not delete the the source and temporary files after the merge process. .TP .B nodoc Do not install doc files (/usr/share/doc). .TP .B noinfo Do not install info pages. .TP .B noman Do not install manpages. .TP .B nostrip Prevents the stripping of binaries that are merged to the live filesystem. .TP .B notitles Disables xterm titlebar updates (which contains status info). .TP .B parallel-fetch Fetch in the background while compiling. .TP .B sandbox Enable sandbox\-ing when running \fBemerge\fR(1) and \fBebuild\fR(1). .TP .B severe When checking Manifests, only accept ones that have been signed by a key which you trust. .TP .B sfperms Stands for Smart Filesystem Permissions. Before merging packages to the live filesystem, automatically search for and set permissions on setuid and setgid files. Files that are setuid have the group and other read bits removed while files that are setgid have the other read bit removed. See also \fIsuidctl\fR below. .TP .B sign When commiting work to cvs with \fBrepoman\fR(1), sign the Manifest with a GPG key. Read about the \fIPORTAGE_GPG_KEY\fR variable in \fBmake.conf\fR(5). .TP .B splitdebug Prior to stripping ELF etdyn and etexec files, the debugging info is stored for later use by various debuggers. This feature is disabled by \fBnostrip\fR. For installation of source code, see \fBinstallsources\fR. .TP .B strict Have portage react strongly to conditions that have the potential to be dangerous (like missing or incorrect Manifests). .TP .B stricter Have portage react strongly to conditions that may conflict with system security provisions (for example textrels, executable stack). Read about the \fIQA_STRICT_*\fR variables in \fBmake.conf\fR(5). .TP .B suidctl Before merging packages to the live filesystem, automatically strip setuid bits from any file that is not listed in \fI/etc/portage/suidctl.conf\fR. .TP .B test Run package\-specific tests during each merge to help make sure the package compiled properly. See \fItest\fR in \fBebuild\fR(1) and \fIsrc_test()\fR in \fBebuild\fR(5). .TP .B userfetch When portage is run as root, drop privileges to portage:portage during the fetching of package sources. .TP .B userpriv Allow portage to drop root privileges and compile packages as portage:portage without a sandbox (unless \fIusersandbox\fR is also used). .TP .B usersandbox Enable the sandbox in the compile phase, when running without root privs (\fIuserpriv\fR). .RE .TP .B FETCHCOMMAND This variable contains the command used for fetching package sources from the internet. It must contain the full path to the executable as well as the place-holders \\${DISTDIR} and \\${URI}. .TP \fBGENTOO_MIRRORS\fR = \fI[URLs]\fR Insert your space\-seperated list of local mirrors here. These locations are used to download files before the ones listed in the \fIebuild scripts\fR. Merging 'mirrorselect' can help. .TP \fBhttp_proxy ftp_proxy\fR = \fI[host:port]\fR These vars are used if the sources must be downloaded from the internet by \fBwget\fR(1). They are only required if you use a proxy server for internet access. .TP \fBINSTALL_MASK\fR = \fI[space delimited list of file names]\fR Use this variable if you want to selectively prevent certain files from being copied into your file system tree. This does not work on symlinks, but only on actual files. Useful if you wish to filter out files like HACKING.gz and TODO.gz. .TP .B MAKEOPTS Use this variable if you want to use parallel make. For example, if you have a dual\-processor system, set this variable to "\-j2" or "\-j3" for enhanced build performance with many packages. Suggested settings are between \fICPUs+1\fR and \fI2*CPUs+1\fR. For more information, see \fBmake\fR(1). .TP \fBNOCOLOR\fR = \fI["true" | "false"]\fR Defines if color should be disabled by default. .br Defaults to false. .TP \fBPKGDIR\fR = \fI[path]\fR Defines the location where created .tbz2 binary packages will be stored. .br Defaults to ${PORTDIR}/packages. .TP .B PORT_LOGDIR This variable defines the directory in which per\-ebuild logs are kept. Logs are created only when this is set and writable. .TP \fBPORTAGE_BINHOST\fR = \fI"ftp://login:pass@grp.mirror.site/pub/grp/i686/athlon\-xp"\fR This is the host from which portage will grab prebuilt\-binary packages. The list is a single entry specifying the full address of the directory serving the tbz2's for your system. This is only used when running with the get binary pkg options are given to \fBemerge\fR. Review \fBemerge\fR(1) for more information. Note that it should point to the 'All' directory on the host that creates the binary packages and not to the root of the \fBPKGDIR\fR. .TP \fBPORTAGE_NICENESS\fR = \fI[number]\fR The value of this variable will be added to the current nice level that emerge is running at. In other words, this will not set the nice level, it will increment it. For more information about nice levels and what are acceptable ranges, see \fBnice\fR(1). .TP \fBPORTAGE_RSYNC_EXTRA_OPTS\fR = \fI[rsync options string]\fR Additional rsync options to be used by \fBemerge --sync\fR. .br Defaults to no value. .TP \fBPORTAGE_RSYNC_OPTS\fR = \fI[rsync options string]\fR Default rsync options to be used by \fBemerge --sync\fR. .br \fBDon't change this unless you know exactly what you're doing!\fR .br Defaults to "--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" .TP \fBPORTAGE_RSYNC_RETRIES\fR = \fI[NUMBER]\fR The number of times rsync should retry on failed connections before giving up. .br Defaults to 3. .TP \fBPORTAGE_TMPDIR\fR = \fI[path]\fR Defines the location of the temporary build directories. .br Defaults to /var/tmp. .TP \fBPORTDIR\fR = \fI[path]\fR Defines the location of your Portage tree. .br Defaults to /usr/portage. .TP \fBPORTDIR_OVERLAY\fR = \fI"[path] [different\-path] [etc...]"\fR Defines the directories in which user made ebuilds may be stored and not overwriten when `emerge \-\-sync` is run. This is a space delimited list of directories. .br Defaults to no value. .TP .B RESUMECOMMAND This variable contains the command used for resuming package sources that have been partially downloaded. It should be defined using the same format as \fBFETCHCOMMAND\fR. .TP \fBQA_STRICT_EXECSTACK = \fI"set"\fR Set this to cause portage to ignore any \fIQA_EXECSTACK\fR override settings from ebuilds. See also \fBebuild\fR(5). .TP \fBQA_STRICT_WX_LOAD = \fI"set"\fR Set this to cause portage to ignore any \fIQA_WX_LOAD\fR override settings from ebuilds. See also \fBebuild\fR(5). .TP \fBQA_STRICT_TEXTRELS = \fI"set"\fR Set this to cause portage to ignore any \fIQA_TEXTREL\fR override settings from ebuilds. See also \fBebuild\fR(5). .TP \fBROOT\fR = \fI[path]\fR Use \fBROOT\fR to specify the target root filesystem to be used for merging packages or ebuilds. All \fBRDEPEND\fR and \fBPDEPEND\fR will be installed into \fBROOT\fR while all \fBDEPEND\fR will be still be installed into /. Typically, you should set this setting in the environment rather than in \fI/etc/make.conf\fR itself. It's commonly used for creating new build images. Make sure you use an absolute path. .br Defaults to /. .TP \fBRPMDIR\fR = \fI[path]\fR Defines the location where created RPM packages will be stored. .br Defaults to ${PORTDIR}/rpm. .TP \fBSYNC\fR = \fI[RSYNC]\fR Insert your preferred rsync mirror here. This rsync server is used to sync the local portage tree when `emerge \-\-sync` is run. .br Defaults to rsync://rsync.gentoo.org/gentoo\-portage .TP \fBUSE\fR = \fI[space delimited list of USE items]\fR This variable contains options that control the build behavior of several packages. More information in \fBebuild\fR(5). Possible USE values can be found in \fI/usr/portage/profiles/use.desc\fR. .TP \fBUSE_EXPAND_HIDDEN\fR = \fI[space delimited list of variable names]\fR Names of \fBUSE_EXPAND\fR variables that should not be shown in the verbose merge list output of the \fBemerge\fR(1) command. .TP \fBUSE_ORDER\fR = \fI"env:pkg:conf:auto:defaults"\fR Determines precedence for incrementing the setting of the USE variable. The above setting will cause the environment (env) to override per package (pkg) settings to override make.conf (conf) to override auto generated values from merged packages (auto) to override make.defaults (defaults). .br \fB***warning***\fR .br Do not modify this value unless you're a developer and you know what you're doing. If you change this and something breaks, we will not help you fix it. .br Defaults to "env:pkg:conf:defaults". .SH "REPORTING BUGS" Please report bugs via http://bugs.gentoo.org/ .SH "AUTHORS" .nf Daniel Robbins Nicholas Jones Mike Frysinger Saleem Abdulrasool .fi .SH "FILES" .TP \fB/etc/make.conf\fR Contains variables for the build\-process and overwrites those in make.defaults. .TP \fB/etc/make.globals\fR Contains the default variables for the build\-process, you should edit \fI/etc/make.conf\fR instead. .TP \fB/usr/portage/profiles/use.desc\fR Contains a list of all global USE flags. .TP \fB/usr/portage/profiles/use.local.desc\fR Contains a list of all local USE variables. .SH "SEE ALSO" .BR emerge (1), .BR portage (5), .BR ebuild (1), .BR ebuild (5) .TP The \fI/usr/sbin/ebuild.sh\fR script. .TP The helper apps in \fI/usr/lib/portage/bin\fR.
