.TH "EBUILD" "5" "Jan 2013" "Portage VERSION" "Portage" .SH "NAME" ebuild \- the internal format, variables, and functions in an ebuild script .SH "DESCRIPTION" The \fBebuild\fR(1) program accepts a single ebuild script as an argument. This script contains variables and commands that specify how to download, unpack, patch, compile, install and merge a particular software package from its original sources. In addition to all of this, the ebuild script can also contain pre/post install/remove commands, as required. All ebuild scripts are written in bash. .SS "Dependencies" A \fIdepend atom\fR is simply a dependency that is used by portage when calculating relationships between packages. Please note that if the atom has not already been emerged, then the latest version available is matched. .TP .B Atom Bases The base atom is just a full category/packagename. Examples: .nf .I sys\-apps/sed .I sys\-libs/zlib .I net\-misc/dhcp .fi .TP .B Atom Versions It is nice to be more specific and say that only certain versions of atoms are acceptable. Note that versions must be combined with a prefix (see below). Hence you may add a version number as a postfix to the base. Examples: .nf sys\-apps/sed\fI\-4.0.5\fR sys\-libs/zlib\fI\-1.1.4\-r1\fR net\-misc/dhcp\fI\-3.0_p2\fR .fi Versions are normally made up of two or three numbers separated by periods, such as 1.2 or 4.5.2. This string may be followed by a character such as 1.2a or 4.5.2z. Note that this letter is \fInot\fR meant to indicate alpha, beta, etc... status. For that, use the optional suffix; either _alpha, _beta, _pre (pre\-release), _rc (release candidate), or _p (patch). This means for the 3rd pre\-release of a package, you would use something like 1.2_pre3. The suffixes here can be arbitrarily chained without limitation. .TP .B Atom Prefix Operators [> >= = <= <] Sometimes you want to be able to depend on general versions rather than specifying exact versions all the time. Hence we provide standard boolean operators: Examples: .nf \fI>\fRmedia\-libs/libgd\-1.6 \fI>=\fRmedia\-libs/libgd\-1.6 \fI=\fRmedia\-libs/libgd\-1.6 \fI<=\fRmedia\-libs/libgd\-1.6 \fI<\fRmedia\-libs/libgd\-1.6 .fi .TP .B Extended Atom Prefixes [!~] and Postfixes [*] Now to get even fancier, we provide the ability to define blocking packages and version range matching. Also note that these extended prefixes/postfixes may be combined in any way with the atom classes defined above. .RS .TP .I ~ means match any revision of the base version specified. So in the example below, we would match versions '1.0.2a', '1.0.2a\-r1', '1.0.2a\-r2', etc... Example: .nf \fI~\fRnet\-libs/libnet\-1.0.2a .fi .TP .I ! means block packages from being installed at the same time. Example: .nf \fI!\fRapp\-text/dos2unix .fi .TP .I !! means block packages from being installed at the same time and explicitly disallow them from being temporarily installed simultaneously during a series of upgrades. This syntax is supported beginning with \fBEAPI 2\fR. Example: .nf \fI!!\fR=\fRx11\-libs/qt-3.3.8:3 \fI=\fRx11\-libs/qt-3.3*:3 .fi .TP .B Sub Slots Beginning with \fBEAPI 5\fR, a slot dependency may contain an optional sub\-slot part that follows the regular slot and is delimited by a \fI/\fR character. Examples: .nf dev\-libs/icu:0/0 dev\-libs/icu:0/49 dev\-lang/perl:0/5.12 dev\-libs/glib:2/2.30 .fi .TP .B Atom Slot Operators Beginning with \fBEAPI 5\fR, slot operator dependency consists of a colon followed by one of the following operators: .RS .TP .I * Indicates that any slot value is acceptable. In addition, for runtime dependencies, indicates that the package will not break if the matched package is uninstalled and replaced by a different matching package in a different slot. Examples: .nf dev\-libs/icu:* dev\-lang/perl:* dev-libs/glib:* .fi .TP .I = Indicates that any slot value is acceptable. In addition, for runtime dependencies, indicates that the package will break unless a matching package with slot and sub\-slot equal to the slot and sub\-slot of the best installed version at the time the package was installed is available. Examples: .nf dev\-libs/icu:= dev\-lang/perl:= dev-libs/glib:= .fi .TP .I slot= Indicates that only a specific slot value is acceptable, and otherwise behaves identically to the plain equals slot operator. Examples: .nf dev\-libs/icu:0= dev\-lang/perl:0= dev-libs/glib:2= .fi .PP To implement the equals slot operator, the package manager will need to store the slot/sub\-slot pair of the best installed version of the matching package. This syntax is only for package manager use and must not be used by ebuilds. The package manager may do this by inserting the appropriate slot/sub\-slot pair between the colon and equals sign when saving the package's dependencies. The sub\-slot part must not be omitted here (when the SLOT variable omits the sub\-slot part, the package is considered to have an implicit sub\-slot which is equal to the regular slot). Examples: .nf dev\-libs/icu:0/0= dev\-libs/icu:0/49= dev\-lang/perl:0/5.12= dev-libs/glib:2/2.30= .fi .RE .TP .B Atom USE Beginning with \fBEAPI 2\fR, any atom can be constrained to match specific \fBUSE\fR flag settings. When used together with \fBSLOT\fR dependencies, \fBUSE\fR dependencies appear on the right hand side of \fBSLOT\fR dependencies. .RS .TP .B Unconditional USE Dependencies .TS l l __ l l. Example Meaning foo[bar] foo must have bar enabled foo[bar,baz] foo must have both bar and baz enabled foo[\-bar,baz] foo must have bar disabled and baz enabled .TE .TP .B Conditional USE Dependencies .TS l l __ l l. Compact Form Equivalent Expanded Form foo[bar?] bar? ( foo[bar] ) !bar? ( foo ) foo[!bar?] bar? ( foo ) !bar? ( foo[\-bar] ) foo[bar=] bar? ( foo[bar] ) !bar? ( foo[\-bar] ) foo[!bar=] bar? ( foo[\-bar] ) !bar? ( foo[bar] ) .TE .RE .TP .B Atom USE defaults Beginning with \fBEAPI 4\fR, \fBUSE\fR dependencies may specify default assumptions about values for flags that may or may not be missing from the \fBIUSE\fR of the matched package. Such defaults are specified by immediately following a flag with either \fI(+)\fR or \fI(\-)\fR. Use \fI(+)\fR to behave as if a missing flag is present and enabled, or \fI(\-)\fR to behave as if it is present and disabled: Examples: .nf media\-video/ffmpeg[threads(+)] media\-video/ffmpeg[-threads(\-)] .fi .TP .B Dynamic Dependencies Sometimes programs may depend on different things depending on the USE variable. Portage offers a few options to handle this. Note that when using the following syntaxes, each case is considered as 1 Atom in the scope it appears. That means that each Atom both conditionally include multiple Atoms and be nested to an infinite depth. .RS .TP .B usevar? ( Atom ) To include the jpeg library when the user has jpeg in \fBUSE\fR, simply use the following syntax: jpeg? ( media\-libs/jpeg ) .TP .B !usevar? ( Atom ) If you want to include a package only if the user does not have a certain option in their \fBUSE\fR variable, then use the following syntax: !nophysfs? ( dev\-games/physfs ) This is often useful for those times when you want to want to add optional support for a feature and have it enabled by default. .TP .B usevar? ( Atom if true ) !usevar? ( Atom if false ) For functionality like the tertiary operator found in C you must use two statements, one normal and one inverted. If a package uses GTK2 or GTK1, but not both, then you can handle that like this: gtk2? ( =x11\-libs/gtk+\-2* ) !gtk2? ( =x11\-libs/gtk+\-1* ) That way the default is the superior GTK2 library. .TP .B || ( Atom Atom ... ) When a package can work with a few different packages but a virtual is not appropriate, this syntax can easily be used. Example: .nf || ( app\-games/unreal\-tournament app\-games/unreal\-tournament\-goty ) .fi Here we see that unreal\-tournament has a normal version and it has a goty version. Since they provide the same base set of files, another package can use either. Adding a virtual is inappropriate due to the small scope of it. Another good example is when a package can be built with multiple video interfaces, but it can only ever have just one. Example: .nf || ( sdl? ( media\-libs/libsdl ) svga? ( media\-libs/svgalib ) opengl? ( virtual/opengl ) ggi? ( media\-libs/libggi ) virtual/x11 ) .fi Here only one of the packages will be chosen, and the order of preference is determined by the order in which they appear. So sdl has the best chance of being chosen, followed by svga, then opengl, then ggi, with a default of X if the user does not specify any of the previous choices. Note that if any of the packages listed are already merged, the package manager will use that to consider the dependency satisfied. .SS "Cross-compilation" Portage supports cross-compilation into a subdirectory specified by \fBROOT\fR. .TP .B Host \fIHost\fR in this context means the platform hosting the build process, i.e. what autotools calls CBUILD. Its packages are contained in the root of the filesystem ("\fI/\fR"). If \fBROOT\fR is "\fI/\fR", all dependency types will be installed there. Otherwise, for EAPIs that support \fBHDEPEND\fR (experimental \fBEAPI 5-hdepend\fR), only \fBHDEPEND\fR is installed into "\fI/\fR". For EAPIs that do not support \fBHDEPEND\fR, the behaviour is controlled by the \fI\-\-root-deps\fR flag to \fBemerge\fR(1), defaulting to install only \fBDEPEND\fR into the \fIhost\fR. .TP .B Target \fITarget\fR refers to the platform that the package will later run on, i.e. what autotools calls CHOST. The directory housing this system is specified by \fBROOT\fR. If it is different from "\fI/\fR", i.e. \fIhost\fR and \fItarget\fR are not the same, this variable contains the path to the directory housing the \fItarget\fR system. For EAPIs that support \fBHDEPEND\fR (experimental \fBEAPI 5-hdepend\fR), \fBDEPEND\fR, \fBRDEPEND\fR, and \fBPDEPEND\fR list the \fItarget\fR dependencies, i.e. those to be installed into \fBROOT\fR. For EAPIs that do not support \fBHDEPEND\fR, the \fBemerge\fR(1) flag \fI\-\-root-deps\fR controls what the package manager installs there. Without it, \fBemerge\fR defaults to install only runtime dependencies (i.e. \fBRDEPEND\fR and \fBPDEPEND\fR) into \fBROOT\fR. .PP See section \fBVARIABLES\fR for more information about the \fBDEPEND\fR, \fBRDEPEND\fR and \fBHDEPEND\fR variables. .TP .B The targetroot USE flag For EAPIs that support the "\fItargetroot\fR" USE flag, that flag is automatically enabled by the package manager if \fIhost\fR and \fItarget\fR system are not the same, i.e. if the \fBROOT\fR is not "\fI/\fR". This is necessary where the package to be built needs an executable copy of itself during the build process. A known example is dev-lang/python, which needs to run a Python interpreter during compilation. .SH "VARIABLES" .TP .B Usage Notes \- All variables defined in \fBmake.conf\fR(5) are available for use in ebuilds (such as the PORTAGE* and PORTDIR* variables) .br \- When assigning values to variables in ebuilds, you \fIcannot have a space\fR between the variable name and the equal sign. .br \- Variable values should only contain characters that are members of the \fBascii\fR(7) character set. This requirement is mandated by \fBGLEP 31\fR. .TP .B P This variable contains the package name without the ebuild revision. This variable must NEVER be modified. xfree\-4.2.1\-r2.ebuild \-\-> $P=='xfree\-4.2.1' .TP .B PN Contains the name of the script without the version number. xfree\-4.2.1\-r2.ebuild \-\-> $PN=='xfree' .TP .B PV Contains the version number without the revision. xfree\-4.2.1\-r2.ebuild \-\-> $PV=='4.2.1' .TP .B PR Contains the revision number or 'r0' if no revision number exists. xfree\-4.2.1\-r2.ebuild \-\-> $PR=='r2' .TP .B PVR Contains the version number with the revision. xfree\-4.2.1\-r2.ebuild \-\-> $PVR=='4.2.1\-r2' .TP .B PF Contains the full package name \fBPN\fR\-\fBPVR\fR xfree\-4.2.1\-r2.ebuild \-\-> $PF=='xfree\-4.2.1\-r2' .TP .B CATEGORY Contains the package category name. .TP .B A Contains all source files required for the package. This variable must not be defined. It is autogenerated from the \fBSRC_URI\fR variable. .TP .B WORKDIR\fR = \fI"${PORTAGE_TMPDIR}/portage/${CATEGORY}/${PF}/work" Contains the path to the package build root. Do not modify this variable. .TP .B FILESDIR\fR = \fI"${PORTDIR}/${CATEGORY}/${PN}/files" Contains the path to the 'files' sub folder in the package specific location in the portage tree. Do not modify this variable. .TP .B EBUILD_PHASE Contains the abreviated name of the phase function that is currently executing, such as "setup", "unpack", "compile", or "preinst". .TP .B EBUILD_PHASE_FUNC Beginning with \fBEAPI 5\fR, contains the full name of the phase function that is currently executing, such as "pkg_setup", "src_unpack", "src_compile", or "pkg_preinst". .TP .B EPREFIX Beginning with \fBEAPI 3\fR, contains the offset that this Portage was configured for during installation. The offset is sometimes necessary in an ebuild or eclass, and is available in such cases as ${EPREFIX}. EPREFIX does not contain a trailing slash, therefore an absent offset is represented by the empty string. Do not modify this variable. .TP .B S\fR = \fI"${WORKDIR}/${P}" Contains the path to the temporary \fIbuild directory\fR. This variable is used by the functions \fIsrc_compile\fR and \fIsrc_install\fR. Both are executed with \fIS\fR as the current directory. This variable may be modified to match the extraction directory of a tarball for the package. .TP .B T\fR = \fI"${PORTAGE_TMPDIR}/portage/${CATEGORY}/${PF}/temp" Contains the path to a \fItemporary directory\fR. You may use this for whatever you like. .TP .B D\fR = \fI"${PORTAGE_TMPDIR}/portage/${CATEGORY}/${PF}/image/" Contains the path to the temporary \fIinstall directory\fR. Every write operation that does not involve the helper tools and functions (found below) should be prefixed with ${D}. Beginning with \fBEAPI 3\fR, the offset prefix often needs to be taken into account here, for which the variable ${ED} is provided (see below). Do not modify this variable. .TP .B ED\fR = \fI"${PORTAGE_TMPDIR}/portage/${CATEGORY}/${PF}/image/${EPREFIX}/" Beginning with \fBEAPI 3\fR, contains the path "${D%/}${EPREFIX}/" for convenience purposes. For EAPI values prior to \fBEAPI 3\fR which do not support ED, helpers use \fBD\fR where they would otherwise use ED. Do not modify this variable. .TP .B MERGE_TYPE Beginning with \fBEAPI 4\fR, the MERGE_TYPE variable can be used to query the current merge type. This variable will contain one of the following possible values: .RS .TS l l __ l l. Value Meaning binary previously\-built which is scheduled for merge buildonly source\-build which is not scheduled for merge source source\-build which is scheduled for merge .TE .RE .TP .B PORTAGE_LOG_FILE Contains the path of the build log. If \fBPORT_LOGDIR\fR variable is unset then PORTAGE_LOG_FILE=\fI"${T}/build.log"\fR. .TP .B REPLACED_BY_VERSION Beginning with \fBEAPI 4\fR, the REPLACED_BY_VERSION variable can be used in pkg_prerm and pkg_postrm to query the package version that is replacing the current package. If there is no replacement package, the variable will be empty, otherwise it will contain a single version number. .TP .B REPLACING_VERSIONS Beginning with \fBEAPI 4\fR, the REPLACING_VERSIONS variable can be used in pkg_pretend, pkg_setup, pkg_preinst and pkg_postinst to query the package version(s) that the current package is replacing. If there are no packages to replace, the variable will be empty, otherwise it will contain a space\-separated list of version numbers corresponding to the package version(s) being replaced. Typically, this variable will not contain more than one version, but according to PMS it can contain more. .TP .B ROOT\fR = \fI"/" Contains the path that portage should use as the root of the live filesystem. When packages wish to make changes to the live filesystem, they should do so in the tree prefixed by ${ROOT}. Often the offset prefix needs to be taken into account here, for which the variable ${EROOT} is provided (see below). Do not modify this variable. .TP .B EROOT\fR = \fI"${ROOT%/}${EPREFIX}/" Beginning with \fBEAPI 3\fR, contains "${ROOT%/}${EPREFIX}/" for convenience purposes. Do not modify this variable. .TP .B DESCRIPTION\fR = \fI"A happy little package" Should contain a short description of the package. .TP .B EAPI\fR = \fI"0" Defines the ebuild API version to which this package conforms. If not defined then it defaults to "0". If portage does not recognize the EAPI value then it will mask the package and refuse to perform any operations with it since this means that a newer version of portage needs to be installed first. For maximum backward compatiblity, a package should conform to the lowest possible EAPI. Note that anyone who uses the \fBebuild\fR(1) and \fBrepoman\fR(1) commands with this package will be required to have a version of portage that recognizes the EAPI to which this package conforms. .TP .B SRC_URI\fR = \fI"http://example.com/path/${P}.tar.gz" Contains a list of URIs for the required source files. It can contain multiple URIs for a single source file. The list is processed in order if the file was not found on any of the \fIGENTOO_MIRRORS\fR. Beginning with \fBEAPI 2\fR, the output file name of a given URI may be customized with a "->" operator on the right hand side, followed by the desired output file name. All tokens, including the operator and output file name, should be separated by whitespace. .TP .B HOMEPAGE\fR = \fI"http://example.com/" Should contain a list of URIs for the sources main sites and other further package dependent information. .TP .B KEYWORDS\fR = \fI[\-~][x86,ppc,sparc,mips,alpha,arm,hppa] Should contain appropriate list of arches that the ebuild is know to work/not work. By default if you do not know if an ebuild runs under a particular arch simply omit that KEYWORD. If the ebuild will not work on that arch include it as \-ppc for example. If the ebuild is being submitted for inclusion, it must have ~arch set for architectures where it has been PROVEN TO WORK. (Packages KEYWORDed this way may be unmasked for testing by setting ACCEPT_KEYWORDS="~arch" on the command line, or in \fBmake.conf\fR(5)) For an authoritative list please review /usr/portage/profiles/arch.list. Please keep this list in alphabetical order. .TP .B SLOT This sets the SLOT for packages that may need to have multiple versions co\-exist. By default you should set \fBSLOT\fR="0". If you are unsure, then do not fiddle with this until you seek some guidance from some guru. This value should \fINEVER\fR be left undefined. Beginning with \fBEAPI 5\fR, the SLOT variable may contain an optional sub\-slot part that follows the regular slot and is delimited by a / character. The sub\-slot must be a valid slot name. The sub\-slot is used to represent cases in which an upgrade to a new version of a package with a different sub\-slot may require dependent packages to be rebuilt. When the sub\-slot part is omitted from the SLOT definition, the package is considered to have an implicit sub\-slot which is equal to the regular slot. Refer to the \fBAtom Slot Operators\fR section for more information about sub\-slot usage. .TP .B LICENSE This should be a space delimited list of licenses that the package falls under. This \fB_must_\fR be set to a matching license in /usr/portage/licenses/. If the license does not exist in portage yet, you must add it first. .TP .B IUSE This should be a list of any and all USE flags that are leveraged within your build script. The only USE flags that should not be listed here are arch related flags (see \fBKEYWORDS\fR). Beginning with \fBEAPI 1\fR, it is possible to prefix flags with + or - in order to create default settings that respectively enable or disable the corresponding \fBUSE\fR flags. For details about \fBUSE\fR flag stacking order, refer to the \fBUSE_ORDER\fR variable in \fBmake.conf\fR(5). Given the default \fBUSE_ORDER\fR setting, negative IUSE default settings are effective only for negation of repo\-level USE settings, since profile and user configuration settings override them. .TP .B DEPEND This should contain a list of all packages that are required for the program to compile (aka \fIbuildtime\fR dependencies). These are usually libraries and headers. Starting from experimental \fBEAPI 5-hdepend\fR, tools should go into the \fBHDEPEND\fR variable instead, as \fBDEPEND\fR will only be installed into the \fItarget\fR system and hence cannot be executed in a cross\-compile setting. (See section \fBCross\-compilation\fR for more information.) You may use the syntax described above in the \fBDependencies\fR section. .TP .B RDEPEND This should contain a list of all packages that are required for this program to run (aka \fIruntime\fR dependencies). These are usually libraries. In \fBEAPI 3\fR or earlier, if this is not set, then it defaults to the value of \fBDEPEND\fR. In \fBEAPI 4\fR or later, \fBRDEPEND\fR will never be implicitly set. You may use the syntax described above in the \fBDependencies\fR section. .TP .B HDEPEND This should contain a list of all packages that are required to be executable during compilation of this program (aka \fIhost\fR buildtime dependencies). These are usually tools, like interpreters or (cross\-)compilers. This variable is new in experimental \fBEAPI 5-hdepend\fR and will be installed into the \fIhost\fR system. (See section \fBCross-compilation\fR for more information.) You may use the syntax described above in the \fBDependencies\fR section. .TP .B PDEPEND This should contain a list of all packages that should be merged after this one (aka \fIpost\fR merge dependencies), but which may be installed by the package manager at any time, if that is not possible. .B ***WARNING*** .br Use this only as last resort to break cyclic dependencies! You may use the syntax described above in the \fBDependencies\fR section. .TP .B REQUIRED_USE Beginning with \fBEAPI 4\fR, the \fBREQUIRED_USE\fR variable can be used to specify combinations of \fBUSE\fR flags that are allowed or not allowed. Elements can be nested when necessary. .TS l l __ l l. Behavior Expression If flag1 enabled then flag2 disabled flag1? ( !flag2 ) If flag1 enabled then flag2 enabled flag1? ( flag2 ) If flag1 disabled then flag2 enabled !flag1? ( flag2 ) If flag1 disabled then flag2 disabled !flag1? ( !flag2 ) Must enable any one or more (inclusive or) || ( flag1 flag2 flag3 ) Must enable exactly one but not more (exclusive or) ^^ ( flag1 flag2 flag3 ) May enable at most one (EAPI 5 or later) ?? ( flag1 flag2 flag3 ) .TE .TP .B RESTRICT\fR = \fI[strip,mirror,fetch,userpriv] This should be a space delimited list of portage features to restrict. You may use conditional syntax to vary restrictions as seen above in DEPEND. .PD 0 .RS .TP .I binchecks Disable all QA checks for binaries. This should ONLY be used in packages for which binary checks make no sense (linux\-headers and kernel\-sources, for example, can safely be skipped since they have no binaries). If the binary checks need to be skipped for other reasons (such as proprietary binaries), see the \fBQA CONTROL VARIABLES\fR section for more specific exemptions. .TP .I bindist Distribution of built packages is restricted. .TP .I fetch like \fImirror\fR but the files will not be fetched via \fBSRC_URI\fR either. .TP .I installsources Disables installsources for specific packages. This is for packages with binaries that are not compatible with debugedit. .TP .I mirror files in \fBSRC_URI\fR will not be downloaded from the \fBGENTOO_MIRRORS\fR. .TP .I primaryuri fetch from URIs in \fBSRC_URI\fR before \fBGENTOO_MIRRORS\fR. .TP .I strip final binaries/libraries will not be stripped of debug symbols. .TP .I test do not run src_test even if user has \fBFEATURES\fR=test. .TP .I userpriv Disables userpriv for specific packages. .RE .PD 1 .TP .B PROPERTIES\fR = \fI[interactive] A space delimited list of properties, with conditional syntax support. .PD 0 .RS .TP .I interactive One or more ebuild phases will produce a prompt that requires user interaction. .RE .PD 1 .TP .B PROVIDE\fR = \fI"virtual/TARGET" This variable should only be used when a package provides a virtual target. For example, blackdown\-jdk and sun\-jdk provide \fIvirtual/jdk\fR. This allows for packages to depend on \fIvirtual/jdk\fR rather than on blackdown or sun specifically. .TP .B DOCS Beginning with \fBEAPI 4\fR, an array or space\-delimited list of documentation files for the default src_install function to install using dodoc. If undefined, a reasonable default list is used. See the documentation for src_install below. .SS "QA Control Variables:" .TP .B Usage Notes Several QA variables are provided which allow an ebuild to manipulate some of the QA checks performed by portage. Use of these variables in ebuilds should be kept to an absolute minimum otherwise they defeat the purpose of the QA checks, and their use is subject to agreement of the QA team. They are primarily intended for use by ebuilds that install closed\-source binary objects that cannot be altered. Note that objects that violate these rules may fail on some architectures. .TP .B QA_PREBUILT This should contain a list of file paths, relative to the image directory, of files that are pre\-built binaries. Paths listed here will be appended to each of the QA_* variables listed below. The paths may contain fnmatch\-like patterns which will be internally translated to regular expressions for the QA_* variables that support regular expressions instead of fnmatch patterns. The translation mechanism simply replaces "*" with ".*". .TP .B QA_TEXTRELS This variable can be set to a list of file paths, relative to the image directory, of files that contain text relocations that cannot be eliminated. The paths may contain fnmatch patterns. This variable is intended to be used on closed\-source binary objects that cannot be altered. .TP .B QA_EXECSTACK This should contain a list of file paths, relative to the image directory, of objects that require executable stack in order to run. The paths may contain fnmatch patterns. This variable is intended to be used on objects that truly need executable stack (i.e. not those marked to need it which in fact do not). .TP .B QA_WX_LOAD This should contain a list of file paths, relative to the image directory, of files that contain writable and executable segments. These are rare. The paths may contain fnmatch patterns. .TP .B QA_FLAGS_IGNORED This should contain a list of file paths, relative to the image directory, of files that do not contain .GCC.command.line sections or contain .hash sections. The paths may contain regular expressions with escape\-quoted special characters. This variable is intended to be used on files of binary packages which ignore CFLAGS, CXXFLAGS, FFLAGS, FCFLAGS, and LDFLAGS variables. .TP .B QA_MULTILIB_PATHS This should contain a list of file paths, relative to the image directory, of files that should be ignored for the multilib\-strict checks. The paths may contain regular expressions with escape\-quoted special characters. .TP .B QA_PRESTRIPPED This should contain a list of file paths, relative to the image directory, of files that contain pre-stripped binaries. The paths may contain regular expressions with escape\-quoted special characters. .TP .B QA_SONAME This should contain a list of file paths, relative to the image directory, of shared libraries that lack SONAMEs. The paths may contain regular expressions with escape\-quoted special characters. .TP .B QA_SONAME_NO_SYMLINK This should contain a list of file paths, relative to the image directory, of shared libraries that have SONAMEs but should not have a corresponding SONAME symlink in the same directory. The paths may contain regular expressions with escape\-quoted special characters. .TP .B QA_AM_MAINTAINER_MODE This should contain a list of lines containing automake missing \-\-run commands. The lines may contain regular expressions with escape\-quoted special characters. .TP .B QA_CONFIGURE_OPTIONS This should contain a list of configure options which trigger warnings about unrecognized options. The options may contain regular expressions with escape\-quoted special characters. .TP .B QA_DT_NEEDED This should contain a list of file paths, relative to the image directory, of shared libraries that lack NEEDED entries. The paths may contain regular expressions with escape\-quoted special characters. .TP .B QA_DESKTOP_FILE This should contain a list of file paths, relative to the image directory, of desktop files which should not be validated. The paths may contain regular expressions with escape\-quoted special characters. .SH "PORTAGE DECLARATIONS" .TP .B inherit Inherit is portage's maintenance of extra classes of functions that are external to ebuilds and provided as inheritable capabilities and data. They define functions and set data types as drop\-in replacements, expanded, and simplified routines for extremely common tasks to streamline the build process. Call to inherit cannot depend on conditions which can vary in given ebuild. Specification of the eclasses contains only their name and not the \fI.eclass\fR extension. Also note that the inherit statement must come before other variable declarations unless these variables are used in global scope of eclasses. .SH "PHASE FUNCTIONS" .TP .B pkg_pretend Beginning with \fBEAPI 4\fR, this function can be defined in order to check that miscellaneous requirements are met. It is called as early as possible, before any attempt is made to satisfy dependencies. If the function detects a problem then it should call eerror and die. The environment (variables, functions, temporary directories, etc..) that is used to execute pkg_pretend is not saved and therefore is not available in phases that execute afterwards. .TP .B pkg_nofetch This function will be executed when the files in \fBSRC_URI\fR cannot be fetched for any reason. If you turn on \fIfetch\fR in \fBRESTRICT\fR, this is useful for displaying information to the user on *how* to obtain said files. All you have to do is output a message and let the function return.

The usex helper is available beginning with \fBEAPI 5\fR. .TP .B use_with\fR \fI\fR \fI[configure name]\fR \fI[configure opt] Useful for creating custom options to pass to a configure script. If \fIUSE item\fR is in the \fBUSE\fR variable and a \fIconfigure opt\fR is specified, then the string \fI\-\-with\-[configure name]=[configure opt]\fR will be echoed.

It is a \fBbash\fR(1) setting. .TP .B has_version\fR \fI[\-\-host\-root]\fR \fI Check to see if \fIcategory/package\-version\fR is installed on the system. The parameter accepts all values that are acceptable in the \fBDEPEND\fR variable. The function returns 0 if \fIcategory/package\-version\fR is installed, 1 otherwise. Beginning with \fBEAPI 5\fR, the \-\-host\-root option may be used in order to cause the query to apply to the host root instead of ${ROOT}. .TP .B best_version\fR \fI[\-\-host\-root]\fR \fI This function will look up \fIpackage name\fR in the database of currently installed programs and echo the "best version" of the package that is currently installed.
