##Top Makefile to build the Minix libraries for ack and gnu
|
||||
#
|
||||
##needed in makefile that includes this file:
|
||||
#
|
||||
##libraries to build without .a:
|
||||
#LIBRARIES=liba libb libc
|
||||
#
|
||||
##object files per library:
|
||||
#liba_OBJECTS=filea2.o filea2.o
|
||||
#libb_OBJECTS=fileb.o
|
||||
#libc_OBJECTS=filec.o
|
||||
#
|
||||
##if it has subdirectories
|
||||
#SUBDIRS=subdir1 subdir2
|
||||
#
|
||||
#
|
||||
##The main Makefile has to specify the ack and gnu base object directories:
|
||||
#ACKBASE=/path/to/ack-obj
|
||||
#GNUBASE=/path/to/gnu-obj
|
||||
##or relative in this way:
|
||||
#ACKBASE=$(CURDIR)/ack-obj
|
||||
#GNUBASE=$(CURDIR)/gnu-obj
|
||||
#
|
||||
##All these variables have to be set before including this Makefile
|
||||
#
|
||||
#
|
||||
##To customize dependencies for targets you can do the following
|
||||
#$(call ADDDEPENDENCIES,filea2.o fileb.o,header1.h header2.h)
|
||||
#
|
||||
##And to customize MAKE variables for targets use the same construct this way
|
||||
#$(call ADDDEPENDENCIES,filea2.o fileb.o,CFLAGS+=-D_EXTRA_DEFINES -g)
|
||||
#
|
||||
##Only one variable can be set per call to ADDDEPENDENCIES
|
||||
#
|
||||
|
||||
##Object files that must end up in the top level object directory must be in
|
||||
##then variable named TOPLEVEL_OBJECTS
