6# 6# @MAINTAINER:
7# This eclass is for general purpose functions that most ebuilds 7# base-system@gentoo.org
8# have to implement themselves. 8# @BLURB: many extra (but common) functions that are used in ebuilds
9# 9# @DESCRIPTION:
10# NB: If you add anything, please comment it! 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!

46# This function generate linker scripts in /usr/lib for dynamic

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
