40# By default, we define the source directory for libraries to be
41# one level up from the ISA-specific directory, where the code is
42# actually built.  Many libraries define a 'common' directory to
43# contain the source.  These libraries must redefine SRCDIR as:
44#	SRCDIR = ../common
45# Other variations are possible (../port, ../src, etc).
46#
47SRCDIR =	..
48
49#
50# We define MAPFILES here for the benefit of most libraries, those that
51# follow the convention of having source files and other common files
52# in the $(SRCDIR) directory.  Libraries that do not follow this
53# convention must define MAPFILES, or MAPFILEDIR for themselves.
54# Libraries that do follow this convention but that need supplemental
55# ISA-specific mapfiles can augment MAPFILES like this:
56#	MAPFILES += mapfile-vers
57#

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

75#	LIBS = $(LIBRARY)
76# or:
77#	LIBS = $(LIBRARYCCC)
