# Generic Makefile for C/C++ Program


#


# Author: whyglinux (whyglinux AT hotmail DOT com)


# Date:   2006/03/04






# Description:


# The makefile searches in <SRCDIRS> directories for the source files


# with extensions specified in <SOURCE_EXT>, then compiles the sources


# and finally produces the <PROGRAM>, the executable file, by linking


# the objectives.






# Usage:


#   $ make           compile and link the program.


#   $ make objs      compile only (no linking. Rarely used).


#   $ make clean     clean the objectives and dependencies.


#   $ make cleanall  clean the objectives, dependencies and executable.


#   $ make rebuild   rebuild the program. The same as make clean && make all.


#==============================================================================






## Customizing Section: adjust the following if necessary.


##=============================================================================






# The executable file name.


# It must be specified.


# PROGRAM   := a.out    # the executable name


PROGRAM   := main






# The directories in which source files reside.


# At least one path should be specified.


# SRCDIRS   := .        # current directory


SRCDIRS   := .






# The source file types (headers excluded).


# At least one type should be specified.


# The valid suffixes are among of .c, .C, .cc, .cpp, .CPP, .c++, .cp, or .cxx.


# SRCEXTS   := .c      # C program


# SRCEXTS   := .cpp    # C++ program


# SRCEXTS   := .c .cpp # C/C++ program


SRCEXTS   := .cpp






# The flags used by the cpp (man cpp for more).


# CPPFLAGS  := -Wall -Werror # show all warnings and take them as errors


CPPFLAGS  := -g


CPPFLAGS  += -Wno-deprecated






# The compiling flags used only for C.


# If it is a C++ program, no need to set these flags.


# If it is a C and C++ merging program, set these flags for the C parts.


CFLAGS    := -g


CFLAGS    +=






# The compiling flags used only for C++.


# If it is a C program, no need to set these flags.


# If it is a C and C++ merging program, set these flags for the C++ parts.


CXXFLAGS  := -g


CXXFLAGS  +=






# The library and the link options ( C and C++ common).


LDFLAGS   := -lpthread


LDFLAGS   +=






## Implict Section: change the following only when necessary.


##=============================================================================


# The C program compiler. Uncomment it to specify yours explicitly.


#CC      = gcc






# The C++ program compiler. Uncomment it to specify yours explicitly.


CXX     = g++






# Uncomment the 2 lines to compile C programs as C++ ones.


#CC      = $(CXX)


#CFLAGS  = $(CXXFLAGS)






# The command used to delete file.


#RM        = rm -f






## Stable Section: usually no need to be changed. But you can add more.


##=============================================================================


SHELL   = /bin/sh


SOURCES = $(foreach d,$(SRCDIRS),$(wildcard $(addprefix $(d)/*,$(SRCEXTS))))


OBJS    = $(foreach x,$(SRCEXTS), \


      $(patsubst %$(x),%.o,$(filter %$(x),$(SOURCES))))
