linux Makefile（中文版1）
#############################################################################
# Generic Makefile for C/C++ Program
# 用法：
# ------
# 1. 拷贝Makefile到你的代码目录下
# 2. 只有在必要时"Customizable Section"自定义
# * 为了使用非标准库，设置预编译器和编译器<MY_CFLAGS>，链接器<MY_LIBS>
# * 为了搜索更多目录下的源代码，设置<SRCDIRS>
# * 指定你喜欢的程序名，设置<PROGRAM>
# 3. 打make开始编译你的程序
#
# Make Target:
# ------------
# The Makefile provides the following targets to make:
# $ make compile and link
# $ make NODEP=yes compile and link without generating dependencies
# $ make objs compile only (no linking)
# $ make tags create tags for Emacs editor
# $ make ctags create ctags for VI editor
# $ make clean clean objects and the executable file
# $ make distclean clean objects, the executable and dependencies
# $ make help get the usage of the makefile
#
#===========================================================================
## Customizable Section: adapt those variables to suit your program.
##==========================================================================
# 预编译器和编译器选项
# MY_CFLAGS = -ggdb3 -pipe -O2 -Wall -Wextra -fopenmp -march=native -mfpmath=sse -DLINUX -m64 -std=c++0x
MY_CFLAGS = -g -DLINUX -Itest1/include -Itest2/include -Itest1/include/test1 -Itest2/include/test2
# 链接器选项，貌似又写成LIBS，如LIBS = -lmysqlclient -liconv，指定要链接的库
# MY_LIBS = -lGLEW -lglut -lGLU -lGL -lX11 -lXmu -lXi -lm -L/usr/X11R6/lib -lgomp -lOpenThreads -lpthread
MY_LIBS = -lm
# cpp使用的预编译器,如CPPFLAGS='-I/usr/local/libjpeg/include -I/usr/local/libpng/include' (man cpp for more).
CPPFLAGS =
# 链接器选项和链接器ld怎么用，如LDFLAGS = -L/var/xxx/lib -L/opt/mysql/lib -Wl,R/var/xxx/lib -Wl,R/opt/mysql/lib
LDFLAGS =
# 源文件目录
# If not specified, only the current directory will be serached.
SRCDIRS =
# 可执行文件名
# If not specified, current directory name or `a.out' will be used.
PROGRAM =
## Implicit Section: 必要时修改
##==========================================================================
# 源文件类型(headers excluded).
# .c是C语言文件,其它的是C++文件.
SRCEXTS = .c .C .cc .cpp .CPP .c++ .cxx .cp
# 头文件类型

# 用户可以在命令行中重写这些变量U
