6# @MAINTAINER:
7# base-system@gentoo.org
8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
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.
4# 14#
5# Author: Martin Schlemmer <azarah@gentoo.org> 15# Due to the nature of this eclass, some functions may have maintainers
6# 16# different from the overall eclass!
7# This eclass is for general purpose functions that most ebuilds
8# have to implement themselves.

46# This function generate linker scripts in /usr/lib for dynamic
47# libs in /lib. This is to fix linking problems when you have
48# the .so in /lib, and the .a in /usr/lib. What happens is that
49# in some cases when linking dynamic, the .a in /usr/lib is used
50# instead of the .so in /lib due to gcc/libtool tweaking ld's
51# library search path. This cause many builds to fail.
52# See bug #4411 for more info.

54# To use, simply call:
55#
56# gen_usr_ldscript libfoo.so

1626# @DESCRIPTION:
1627# A temporary hack until portage properly supports DEPENDing on USE
1628# flags being enabled in packages. This will check to see if the specified
1629# DEPEND atom was built with the specified list of USE flags. The
1630# --missing option controls the behavior if called on a package that does
1631# not actually support the defined USE flags (aka listed in IUSE).
1632# The default is to abort (call die). The -a and -o flags control
1633# the requirements of the USE flags. They correspond to "and" and "or"
1634# logic. So the -a flag means all listed USE flags must be enabled
1635# while the -o flag means at least one of the listed fIUSE flags must be
1636# enabled. The --hidden option is really for internal use only as it
1637# means the USE flag we're checking is hidden expanded, so it won't be found
1638# in IUSE like normal USE flags.
