Helpers
unpack
Support for the xz file extension
The unpack helper now supports the xz file extension.
Support for installation prefix
Helpers
Beginning with EAPI 3, all helpers use ${ED} instead of ${D}
when appropriate. For example, see econf and einstall below.
econf
${ECONF_SOURCE:-.}/configure \
${CBUILD:+--build=${CBUILD}} \
--datadir="${EPREFIX}"/usr/share \
--host=${CHOST} \
--infodir="${EPREFIX}"/usr/share/info \
--localstatedir="${EPREFIX}"/var/lib \
--prefix="${EPREFIX}"/usr \
--mandir="${EPREFIX}"/usr/share/man \
--sysconfdir="${EPREFIX}"/etc \
${CTARGET:+--target=${CTARGET}} \
${EXTRA_ECONF} \
configure options || die "econf failed"
einstall
Note that, for make-based packages, 'emake install DESTDIR=${D}' (with
DESTDIR=${D} rather than ${ED}) is still preferred over einstall.
make \
prefix=${ED}/usr \
datadir=${ED}/usr/share \
infodir=${ED}/usr/share/info \
localstatedir=${ED}/var/lib \
mandir=${ED}/usr/share/man \
sysconfdir=${ED}/etc \
${EXTRA_EINSTALL} \
make options \
install
Variables
Installation Prefix Variables
Variable Name
Description
ED
Contains the path
"${D%/}${EPREFIX}/" for convenience purposes.
For EAPI values prior to EAPI 3 which do not
support ${ED}, helpers use ${D} where they would
otherwise use ${ED}. Do not modify this variable.
EPREFIX
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 ${EPREFIX}. EPREFIX does not contain a
trailing slash, therefore an absent offset is
represented by the empty string. Do not modify
this variable.
EROOT
Contains
"${ROOT%/}${EPREFIX}/" for convenience purposes.
Do not modify this variable.
