# 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 := -Wall -g
# 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 :=
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 :=
CXXFLAGS +=
# The library and the link options ( C and C++ common).
LDFLAGS :=
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++
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
RM = rm -f
## Stable Section: usually no need to be changed. But you can add more.
##=============================================================================
