Bug 296701 – installation prefix support (EAPI 3)

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Zac Medico 2009-12-13 06:54:29 UTC]

This includes support for installation prefix via new ED, EPREFIX, and EROOT variables which are set automatically by the package manager:

EPREFIX: the prefix that Portage was configured for during installation
ED:      "${D%/}${EPREFIX}/"
EROOT:   "${ROOT%/}${EPREFIX}/"

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:

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

Note that, for make-based packages, 'emake install DESTDIR=${D}' (with DESTDIR=${D} rather than ${ED}) is still preferred over einstall.

This is supported by portage 2.1.7.14 and 2.2_rc59 with EAPI 3_pre2. See `man 5 ebuild` and/or the "EAPI 3_pre2" section of the html docs that are installed with USE=doc.
