本文深入探讨了一种使用纯手写Makefile进行项目构建的方法，通过定义可复用的模板来提高效率并减少重复工作。具体介绍了Makefile中变量、规则和依赖性的设置技巧，以及如何实现不同构建配置的快速切换。

项目领导要求比较高，全部是手写makefile，没有借助autotools或者cmake之类，不过却形成了一个可以复用的定义模板：

ifdef release
DIR = .
LIB_DIR    = ${DIR}/../../../lib/fep
DEPS       = -lplatform -lappconf -lconfig -ltinyxml -lkhreadline
CFLAGS     = -O2 -fPIC -rdynamic -Wall
LDFLAGS    = -fPIC -m64 -lreadline -lncurses -Wall
else
DIR        = $(shell pwd)
LIB_DIR    = 
DEPS       = ${LIB_DIR}/libplatform.so
CFLAGS     = -O2 -fPIC -rdynamic -pg -Wall
LDFLAGS    = -fPIC -m64 -lreadline -lncurses -pg -Wall
endif

OBJ_DIR    = 
BIN_DIR    = 

CC         = g++
LDLIBS     = -shared

TARGETS    = ${BIN_DIR}/fepconfig
LDTARGETS  = ${LIB_DIR}/libconfig.so
BINOBJS    = 
OBJECTS    = $(patsubst cpp/%.cpp,${OBJ_DIR}/%.o,$(wildcard cpp/*.cpp))
SOURCES    = $(wildcard cpp/*.cpp)
TARG_OBJS  = $(patsubst %.cpp,${OBJ_DIR}/%.o,$(wildcard *.cpp))

VPATH      = .:${DIR}/../platform:${OBJ_DIR}:${LIB_DIR}

             -I${DIR}/../platform/readline \
             -Iappconf/include \
             -I./include \
             -I../protocol/include \
             -Itinyxml

APPCONF    = ${LIB_DIR}/libappconf.so
TINYXML    = ${LIB_DIR}/libtinyxml.so

.PHONY:all clean
