545# This function is for AIX only.
546#
547# Showing a sample IMO is the best description:
548#
549# First, AIX has its own /usr/lib/libiconv.a containing 'shr.o' and 'shr4.o'.
550# Both of them are shared-objects packed into an archive, thus /usr/lib/libiconv.a
551# is a shared library (!), even it is called lib*.a.
552# This is the default layout on aix for shared libraries.
553# Read the ld(1) manpage for more information.
554#
555# But now, we want to install GNU libiconv (sys-libs/libiconv) both as
556# shared and static library.
557# AIX (since 4.3) can create shared libraries if '-brtl' or '-G' linker flags
558# are used.
559#
560# Now assume we have GNU tar installed while GNU libiconv was not.
561# This tar now has a runtime dependency on "libiconv.a(shr4.o)".
562# With our ld-wrapper (from sys-devel/binutils-config) we add EPREFIX/usr/lib
563# as linker path, thus it is recorded as loader path into the binary.
564#
565# When having libiconv.a (the static GNU libiconv) in prefix, the loader finds
566# that one and claims that it does not contain an 'shr4.o' object file:
567#
568# Could not load program tar:
569# Dependent module EPREFIX/usr/lib/libiconv.a(shr4.o) could not be loaded.
570# Member shr4.o is not found in archive
571#
572# According to gcc's "host/target specific installation notes" for *-ibm-aix* [1],
573# we can extract that 'shr4.o' from /usr/lib/libiconv.a, mark it as
574# non-linkable, and include it in our new static library.
575#
576# [1] http://gcc.gnu.org/install/specific.html#x-ibm-aix
