39# By default, we define the source directory for libraries to be
40# one level up from the ISA-specific directory, where the code is
41# actually built.  Many libraries define a 'common' directory to
42# contain the source.  These libraries must redefine SRCDIR as:
43#	SRCDIR = ../common
44# Other variations are possible (../port, ../src, etc).
45#
46SRCDIR =	..
47
48#
49# We define MAPFILES here for the benefit of most libraries, those that
50# follow the convention of having source files and other common files
51# in the $(SRCDIR) directory.  Libraries that do not follow this
52# convention must define MAPFILES, or MAPFILEDIR for themselves.
53# Libraries that do follow this convention but that need supplemental
54# ISA-specific mapfiles can augment MAPFILES like this:
55#	MAPFILES += mapfile-vers
56#

60#
61# If HDRDIR is left unset, then it's possible for the $(ROOTHDRDIR)/%
62# install rule in lib/Makefile.targ to generate false matches if there
63# are any common directory names between / and /usr/include (`xfn' is
64# one common example).  To prevent this, we set HDRDIR to a directory
65# name that will almost surely not exist on the build machine.

70# We don't build archive (*.a) libraries by default anymore.

74#	LIBS = $(LIBRARY)
75# or:
76#	LIBS = $(LIBRARYCCC)
77# Archive libraries must not be installed in the proto area.
