### ALL CONFIGURATION SHOULD BE IN CONFIG.MK, NOT HERE
include config.mk

### Module directories
MODULES := $(OSDIR) common

### Look for include files in each of the modules
CPPFLAGS += $(patsubst %,-I%,$(MODULES))
CPPFLAGS += -g -Wextra -Wall -Wno-unused-parameter

### Extra libraries if required
LIBS :=

### Each module will add to this
SRC :=

BIN := bin/leocad
OBJDIR := obj

ifeq ($(findstring $(MAKECMDGOALS), help config-help config clean veryclean source-tgz source-zip), )
-include $(OSDIR)/config.mk
endif

### Include the description for each module
include $(patsubst %,%/module.mk,$(MODULES))

### Determine the object files
OBJ := $(patsubst %.cpp,$(OBJDIR)/%.o,$(filter %.cpp,$(SRC)))

### Link the program
.PHONY: all static

all: $(BIN)

static: bin/leocad.static

bin/leocad: $(OBJ) bin Makefile
	@echo Linking $@
	@$(CXX) -o $@ $(OBJ) $(LIBS) $(LDFLAGS)

bin/leocad.static: $(OBJ) bin Makefile
	$(CXX) -static -o $@ $(OBJ) $(LIBS) $(LDFLAGS)

bin:
	@mkdir bin

obj:
	@mkdir $(OBJDIR) $(addprefix $(OBJDIR)/,$(MODULES))

### Include the C/C++ include dependencies
ifeq ($(findstring $(MAKECMDGOALS), help config-help config clean veryclean source-tgz source-zip), )
-include $(OBJ:.o=.d)
endif

### Calculate C/C++ include dependencies
$(OBJDIR)/%.d: %.cpp obj $(OSDIR)/config.mk
	@$(CXX) -MM -MT '$(patsubst %.d,%.o, $@)' $(CXXFLAGS) $(CPPFLAGS) -w $< > $@
	@[ -s $@ ] || rm -f $@

### Main compiler rule
$(OBJDIR)/%.o: %.cpp obj $(OSDIR)/config.mk
	@echo $<
	@$(CXX) $(CXXFLAGS) $(CPPFLAGS) -c -o '$(patsubst %.cpp,%.o, $@)' $<
	@[ -s $@ ] || rm -f $@

### Various cleaning functions
.PHONY: clean distclean veryclean spotless all

clean:
	@[ ! -d $(OBJDIR) ] || find $(OBJDIR) -name \*.o | xargs rm -f

veryclean: clean
	@rm -rf $(OBJDIR)
	@rm -rf bin
	@rm -rf arch $(OSDIR)/config.mk

distclean: veryclean

### Dependency stuff is done automatically, so these do nothing.
.PHONY: dep depend


### Help function
.PHONY: help

help:
	@echo   'Possible Targets are:'
	@echo   '       help (this is it)'
	@echo   '       all'
	@echo   '       install'
	@echo   '       uninstall'
	@echo   '       binary'
	@echo   '       source'
	@echo   '       (binary and source can be called as'
	@echo   '        a -zip or -tgz variants)'
	@echo   '       clean'
	@echo   '       veryclean'
	@echo
