      3 # Makefile fragment for building with libnbcompat and associated
      4 # include files.  It can also be used for building just with
      5 # the include files, without the library.
      6 #
      7 # This can be used when the library and include files have been installed
      8 # into TOOLDIR (by "make install" in the src/tools/compat directory),
      9 # or when they have not been installed into TOOLDIR but reside
     10 # in the .OBJDIR associated with src/tools/compat.
     11 #
     12 # Variables:
     13 #
     14 # COMPATLIB_UNINSTALLED:
     15 #		If "yes", then use the files from the .OBJDIR of
     16 #		NETBSDSRCDIR/tools/compat.  Otherwise, use the files
     17 #		from TOOLDIR.
     18 #
     19 # COMPATLIB_NO_LIB:
     20 #		If "yes" then do not use the library (but still use
     21 #		the include files).
     22 #
     23 # Examples:
     24 #
     25 # * Use uninstalled copy of libnbcompat and associated *.h files:
     26 #
     27 #	COMPATLIB_UNINSTALLED= yes
     28 #	COMPATOBJ!=	cd ${NETBSDSRCDIR}/tools/compat && ${PRINTOBJDIR}
     29 #	.-include	"${COMPATOBJ}/defs.mk"
     30 #
     31 # * Use TOOLDIR copy of libnbcompat and associated *.h files:
     32 #
     33 #	.-include	"${TOOLDIR}/share/compat/defs.mk"
     34 #
     35 # * Use TOOLDIR copy of compat *.h files, but do not use libnbcompat.a:
     36 #
     37 #	COMPATLIB_NO_LIB= yes
     38 #	.-include	"${TOOLDIR}/share/compat/defs.mk"
     39 #
     40 # The use of ".-include" instead of ".include" above is because it's
     41 # expected that the file might not exist during "make obj" or "make clean".
     42 #
     43 
     44 .include <bsd.own.mk>

     46 # Use the installed (TOOLDIR) version of the library and headers by default
     47 COMPATLIB_UNINSTALLED ?= no

     49 COMPATLIB_NO_LIB ?= no
