Makefile 编译jsoncpp源码 生成静态库和共享库的例子

生成静态库：
#author: wanguofeng
#date: 2014-02-27
vpath %.cpp
SRC1 = $(wildcard *.cpp ) \
SRC=$(notdir $(SRC1))
OBJ=$(patsubst %.cpp,%.o,$(SRC))
CXXFLAGS += -I inc
LDFLAGS +=
ALL: libjson.a
libjson.a:$(OBJ)
ar -crv $@ $(OBJ) $(LDFLAGS)
.PHONY:clean
clean:
rm -f $(OBJ) libjson.a
#g++ -c json_value.cpp -I include
#g++ -c json_writer.cpp -I include/
#g++ -c json_reader.cpp -I include/
#ar -crv libjsoncpp.a json_reader.o json_value.o json_writer.o

生成共享库：
#author: wanguofeng
#date: 2014-02-27
vpath %.cpp
#vpath %.h inc sites
SRC1 = $(wildcard *.cpp ) \
SRC=$(notdir $(SRC1))
OBJ=$(patsubst %.cpp,%.o,$(SRC))
CXXFLAGS += -I inc -shared -fPIC
LDFLAGS +=
ALL: libjson.so
libjson.so:$(OBJ)
$(CXX) -shared -o $@ $(OBJ) $(LDFLAGS)
.PHONY:clean
clean:
rm -f $(OBJ) libjson.so
