41# By default, we define the source directory for libraries to be
42# one level up from the ISA-specific directory, where the code is
43# actually built.  Many libraries define a 'common' directory to
44# contain the source.  These libraries must redefine SRCDIR as:
45#	SRCDIR = ../common
46# Other variations are possible (../port, ../src, etc).
47#
48SRCDIR =	..

50#
51# We define MAPFILES here for the benefit of most libraries,
52# those that follow the convention of having source files and other
53# common files in the $(SRCDIR) directory.  Libraries that do not
54# follow this convention must define MAPFILES for themselves.
55# Libraries that do follow this convention but that need supplemental
56# ISA-specific mapfiles can augment MAPFILES like this:
57#	MAPFILES += mapfile-vers

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