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

57#
58# If HDRDIR is left unset, then it's possible for the $(ROOTHDRDIR)/%
59# install rule in lib/Makefile.targ to generate false matches if there
60# are any common directory names between / and /usr/include (`xfn' is
61# one common example).  To prevent this, we set HDRDIR to a directory
62# name that will almost surely not exist on the build machine.

67# We don't build archive (*.a) libraries by default anymore.
68# If a component of the build needs to build an archive library
69# for its own internal purposes, it can define LIBS for itself
70# after including Makefile.lib, like this:
71# 	LIBS = $(LIBRARY)
72# or:
73# 	LIBS = $(LIBRARYCCC)
74# Archive libraries must not be installed in the proto area.
