#
#  This is a more sophisticated makefile for qdp applications.
#  This version generates dependencies automatically, rather
#  than having to list them explicitly in the makefile.
#

#
#  First we need to tell the makefile where to find the libraries.
#  For this example, we are specifying that qdp is in a subdirectory of
#  the user's home directory; in an installed version, it would be under
#  /usr/local/lib
#
LDFLAGS=-L${HOME}/qcd/src/qdp++/lib -lqdp

#
#  Here we specify the additional path for include files.  Again we
#  have it under the user's home directory, but an installed version
#  would place things under /usr/local/include
#  
CXXFLAGS=-I${HOME}/qcd/src/qdp++/include/

#
#	Here we list the source routines; note that I keep the sources
#       for the main programs separately, denoted by main_src
sources= mesplq.cc

main_src= t_mesplq.cc

#
#  Now the derived files:
#
#  First the object files
objects = $(sources:.cc=.o)

#
#  The various rules for producing derived files
#
# The dependency files, containing a list of dependencies that will be
# included in the makefile below. This is the modern equivalent of
# makedepend. 
%.d: %.cc
	@ $(CXX) -MM $(CXXFLAGS) $< -o $@

#
#  The object files
%.o: %.cc
	$(CXX) ${CXXFLAGS} -c $< -o $@

#
#  The main programs
all: t_mesplq
.PHONY: all clean


t_mesplq: t_mesplq.o ${objects}
	$(CXX) $(CXXFLAGS) -o $@ $< ${objects} ${LDFLAGS}

#  Yes, cleanup
clean:
	rm -f t_mesplq *.o *.d

#
#  Now list the dependencies.  This is the "modern" equivalent
#  of the old "makedepend" command that avoids us having to specify
#  the header files explicitly.  We have one dependency file for
#  each source file
-include $(sources:.cc=.d) $(main_src:.cc=.d)
