5# This eclass is for general purpose functions that most ebuilds 5# @ECLASS: eutils.eclass
6# have to implement themselves. 6# @MAINTAINER:
7# 7# base-system@gentoo.org
8# NB: If you add anything, please comment it! 8# @BLURB: many extra (but common) functions that are used in ebuilds
9# 9# @DESCRIPTION:
10# Maintainer: see each individual function, base-system@gentoo.org as default 10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

44# in some cases when linking dynamic, the .a in /usr/lib is used
45# instead of the .so in /lib due to gcc/libtool tweaking ld's
46# library search path. This cause many builds to fail.

1596# ex: built_with_use xchat gtk2 1623# flags being enabled in packages. This will check to see if the specified
1597# 1624# DEPEND atom was built with the specified list of USE flags. The
1598# Flags: -a all USE flags should be utilized 1625# --missing option controls the behavior if called on a package that does
1599# -o at least one USE flag should be utilized 1626# not actually support the defined USE flags (aka listed in IUSE).
1600# Note: the default flag is '-a' 1627# The default is to abort (call die). The -a and -o flags control
1628# the requirements of the USE flags. They correspond to "and" and "or"
1629# logic. So the -a flag means all listed USE flags must be enabled
1630# while the -o flag means at least one of the listed fIUSE flags must be
1631# enabled. The --hidden option is really for internal use only as it
1632# means the USE flag we're checking is hidden expanded, so it won't be found
1633# in IUSE like normal USE flags.
