# $NetBSD: libtool-fix-la,v 1.2 2003/09/02 06:59:57 jlam Exp $
#
# For *.la files, in the "relink_command" line, we make the following
# replacements:
#
# "libfoo.la" -> "-L./.libs libfoo.la"
# "dirpath/libfoo.la" -> "-Ldirpath/.libs libfoo.la"
#
# This allows the libraries to be found within ${WRKSRC} during relinking.
# We rely on the proper rpath settings to be set by libtool.
#
# For the *.lai files, in the "dependency_libs" line, we remove redundant
# -Ldir and -llib options. We also make sure that we don't ever reference
# other .la files, only referring to other libraries via the usual
# "-L/path -llib" and making sure that /path is always somewhere under the
# default view. This makes wildcard dependencies work for "overwrite"
# packages by letting libtool find libraries in the default view.
