LEVEL - The level of the current subdirectory from the top of the +# MagicStats view. This level should be expressed as a path, for +# example, ../.. for two levels deep. +# +# 2. DIRS - A list of subdirectories to be built. Fake targets are set up +# so that each of the targets "all", "install", and "clean" each build. +# the subdirectories before the local target. +# +# 3. Source - If specified, this sets the source code filenames. If this +# is not set, it defaults to be all of the .cpp, .c, .y, and .l files +# in the current directory. +# + +# Default Rule: +all :: + +# Default for install is to at least build everything... +install :: + +#-------------------------------------------------------------------- +# Installation configuration options... +#-------------------------------------------------------------------- + +#BinInstDir=/usr/local/bin +#LibInstDir=/usrl/local/lib/xxx +#DocInstDir=/usr/doc/xxx + +#--------------------------------------------------------- +# Compilation options... +#--------------------------------------------------------- + +# Add -L options to the link command lines... +LibPathsO = -L $(LEVEL)/lib/VMCore/Release \ + -L $(LEVEL)/lib/Assembly/Parser/Release \ + -L $(LEVEL)/lib/Assembly/Writer/Release \ + -L $(LEVEL)/lib/Analysis/Release \ + -L $(LEVEL)/lib/Bytecode/Writer/Release \ + -L $(LEVEL)/lib/Bytecode/Reader/Release \ + -L $(LEVEL)/lib/Optimizations/Release + +LibPathsG = $(LibPathsO:Release=Debug) + +# Enable this for profiling support with 'gprof' +#Prof = -pg + +# TODO: Get rid of exceptions! : -fno-exceptions -fno-rtti +CompileCommonOpts = $(Prof) -Wall -Winline -W -Wwrite-strings -Wno-unused -I$(LEVEL)/include + +# Compile a file, don't link... +Compile = $(CXX) -c $(CPPFLAGS) $(CXXFLAGS) $(CompileCommonOpts) +CompileG = $(Compile) -g -D_DEBUG +# Add This for DebugMalloc: -fno-defer-pop +CompileO = $(Compile) -O3 -DNDEBUG -finline-functions -felide-constructors -fnonnull-objects -freg-struct-return -fshort-enums + +# Link final executable +Link = $(CXX) $(Prof) +LinkG = $(Link) -g $(LibPathsG) +LinkO = $(Link) -O3 $(LibPathsO) + +# Create a .so file from a .cpp file... +#MakeSO = $(CXX) -shared $(Prof) +MakeSO = $(CXX) -G $(Prof) +MakeSOG = $(MakeSO) -g +MakeSOO = $(MakeSO) -O3 + +# Create dependancy file from CPP file, send to stdout. +Depend = $(CXX) -MM -I$(LEVEL)/include $(CPPFLAGS) + +# Archive a bunch of .o files into a .a file... +AR = ar cq + +#---------------------------------------------------------- + +# Source includes all of the cpp files, and objects are derived from the +# source files... +ifndef Source +Source = $(wildcard *.cpp *.c *.y *.l) +endif +Objs = $(sort $(addsuffix .o,$(basename $(Source)))) +ObjectsO = $(addprefix Release/,$(Objs)) +ObjectsG = $(addprefix Debug/,$(Objs)) + +#--------------------------------------------------------- +# Handle the DIRS option +#--------------------------------------------------------- + +ifdef DIRS # Only do this if we're using DIRS! + +all :: $(addsuffix /.makeall , $(DIRS)) +install :: $(addsuffix /.makeinstall, $(DIRS)) +clean :: $(addsuffix /.makeclean , $(DIRS)) + +%/.makeall %/.makeclean %/.makeinstall: + cd $(@D); $(MAKE) $(subst $(@D)/.make,,$@) +endif + +#--------------------------------------------------------- +# Handle the LIBRARYNAME option - used when building libs... +#--------------------------------------------------------- + +ifdef LIBRARYNAME +LIBNAME_O := Release/lib$(LIBRARYNAME).so +LIBNAME_G := Debug/lib$(LIBRARYNAME).so + +all:: $(LIBNAME_G) +#$(LIBNAME_O) +# TODO: Enable optimized builds + +$(LIBNAME_O): $(ObjectsO) $(LibSubDirs) Release/.dir + @echo ======= Linking $(LIBRARYNAME) release library ======= + $(MakeSOO) -o $@ $(ObjectsO) $(LibSubDirs) $(LibLinkOpts) + +$(LIBNAME_G): $(ObjectsG) $(LibSubDirs) Debug/.dir + @echo ======= Linking $(LIBRARYNAME) debug library ======= + $(MakeSOG) -o $@ $(ObjectsG) $(LibSubDirs) $(LibLinkOpts) + +endif + + +#--------------------------------------------------------- + +# Create dependacies for the cpp files... +Depend/%.d: %.cpp Depend/.dir + $(Depend) $< | sed 's|$*\.o *|Release/& Debug/& Depend/$(@F)|g' > $@ + +# Create .o files in the ObjectFiles directory from the .cpp files... +Release/%.o: %.cpp Release/.dir Depend/.dir + $(CompileO) $< -o $@ + +Debug/%.o: %.cpp Debug/.dir Depend/.dir + $(CompileG) $< -o $@ + +# Create a .cpp source file from a flex input file... this uses sed to cut down +# on the warnings emited by GCC... +%.cpp: %.l + flex -t $< | sed '/^find_rule/d' | sed 's/void yyunput/inline void yyunput/' | sed 's/void \*yy_flex_realloc/inline void *yy_flex_realloc/' > $@ + +# Rule for building the bison parsers... + +%.cpp %.h : %.y + bison -d -p $(<:%Parser.y=%) $(basename $@).y + mv -f $(basename $@).tab.c $(basename $@).cpp + mv -f $(basename $@).tab.h $(basename $@).h + +# To create the directories... +%/.dir: + mkdir -p $(@D) + @date > $@ + +# Clean does not remove the output files... just the temporaries +clean:: + rm -rf Debug Release Depend + rm -f core *.o *.d *.so *~ *.flc + +# If dependancies were generated for the file that included this file, +# include the dependancies now... +# +SourceDepend = $(addsuffix .d,$(addprefix Depend/,$(basename $(Source)))) +ifneq ($(SourceDepend),) +include $(SourceDepend) +endif |
