37 38 # By default, we define the source directory for libraries to be
38 39 # one level up from the ISA-specific directory, where the code is
39 40 # actually built. Many libraries define a 'common' directory to
40 41 # contain the source. These libraries must redefine SRCDIR as:
41 42 # SRCDIR = ../common
42 43 # Other variations are possible (../port, ../src, etc).
43 44 #
44 45 SRCDIR = ..
45 46
46 47 #
47 48 # We define MAPFILES here for the benefit of most libraries, those that
48 49 # follow the convention of having source files and other common files
49 50 # in the $(SRCDIR) directory. Libraries that do not follow this
50 51 # convention must define MAPFILES, or MAPFILEDIR for themselves.
51 52 # Libraries that do follow this convention but that need supplemental
52 53 # ISA-specific mapfiles can augment MAPFILES like this:
53 54 # MAPFILES += mapfile-vers
54 55 #
55 56 MAPFILEDIR = $(SRCDIR)
56 57 MAPFILES = $(MAPFILEDIR)/mapfile-vers

59 60 # If HDRDIR is left unset, then it's possible for the $(ROOTHDRDIR)/%
60 61 # install rule in lib/Makefile.targ to generate false matches if there
61 62 # are any common directory names between / and /usr/include (`xfn' is
62 63 # one common example). To prevent this, we set HDRDIR to a directory
63 64 # name that will almost surely not exist on the build machine.
