36 36 # By default, we define the source directory for libraries to be
37 37 # one level up from the ISA-specific directory, where the code is
38 38 # actually built. Many libraries define a 'common' directory to
39 39 # contain the source. These libraries must redefine SRCDIR as:
40 40 # SRCDIR = ../common
41 41 # Other variations are possible (../port, ../src, etc).
42 42 #
43 43 SRCDIR = ..
44 44
45 45 #
46 46 # We define MAPFILES here for the benefit of most libraries, those that
47 47 # follow the convention of having source files and other common files
48 48 # in the $(SRCDIR) directory. Libraries that do not follow this
49 49 # convention must define MAPFILES, or MAPFILEDIR for themselves.
50 50 # Libraries that do follow this convention but that need supplemental
51 51 # ISA-specific mapfiles can augment MAPFILES like this:
52 52 # MAPFILES += mapfile-vers
53 53 #
54 54 MAPFILEDIR = $(SRCDIR)
55 55 MAPFILES = $(MAPFILEDIR)/mapfile-vers

59 59 # install rule in lib/Makefile.targ to generate false matches if there
60 60 # are any common directory names between / and /usr/include (`xfn' is
61 61 # one common example). To prevent this, we set HDRDIR to a directory
