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

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

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