1、目录结构如下：

[root@localhost libname]# tree.+-- include¦   +-- headerA.h¦   +-- headerB.h+-- lib+-- Makefile+-- src¦   +-- cppsrcA.cpp¦   +-- cppsrcB.cpp¦   +-- csrcA.c¦   +-- csrcB.c+-- test4 directories, 7 files

 

2、Makefile内容为：

CC           = gccCXX          = g++AR           = ar -rRM           = rm -f#INSTALL     = /usr/bin/install -m 644#INSTALL_BIN = /usr/bin/install -m 755# you can specify LIBTYPE=static when executing make, if you want to create a static libraryifeq ($(LIBTYPE),static)  CFLAGS     = -I./include  CXXFLAGS   = -I./includeelse  CFLAGS     = -I./include -fPIC  CXXFLAGS   = -I./include -fPIC  LDFLAGS    = -fPIC -sharedendifC_SRC        = src/csrcA.c \               src/csrcB.c              CXX_SRC      = src/cppsrcA.cpp \               src/cppsrcB.cppSRC_DIR      = srcSTATIC_OBJ_DIR =lib_obj/static_objDYNAMIC_OBJ_DIR=lib_obj/dynamic_objLIB_DIR      = libSTATIC_LIB   = libname.aDYNAMIC_LIB  = libname.soifeq ($(LIBTYPE),static)  LIB_NAME   = $(STATIC_LIB)  OBJS_DIR   = $(STATIC_OBJ_DIR)else  LIB_NAME   = $(DYNAMIC_LIB)  OBJS_DIR   = $(DYNAMIC_OBJ_DIR)endifC_OBJS       = $(patsubst $(SRC_DIR)/%.c, $(OBJS_DIR)/%.o, $(C_SRC))CXX_OBJS     = $(patsubst $(SRC_DIR)/%.cpp, $(OBJS_DIR)/%.o, $(CXX_SRC))ALL_OBJS     = $(C_OBJS) $(CXX_OBJS)INSTALL_PREFIX=/usr/local/libnameall: $(LIB_NAME)$(STATIC_LIB): $(OBJS_DIR) $(ALL_OBJS)    $(AR) $(LIB_DIR)/$@ $(ALL_OBJS)$(DYNAMIC_LIB): $(OBJS_DIR) $(ALL_OBJS)    $(CC) $(LDFLAGS) $(ALL_OBJS) -o $(LIB_DIR)/$@$(OBJS_DIR):    @if [ ! -d $(OBJS_DIR) ]; then \        echo mkdir -p $(OBJS_DIR) ; \        mkdir -p $(OBJS_DIR); \    fi$(C_OBJS):$(OBJS_DIR)/%.o:$(SRC_DIR)/%.c    $(CC) $(CFLAGS) -c $< -o $@$(CXX_OBJS):$(OBJS_DIR)/%.o:$(SRC_DIR)/%.cpp    $(CXX) $(CXXFLAGS) -c $< -o $@    #install:#uninstall:#test:.PHONY: cleanall cleancleanall: clean    $(RM) $(LIB_DIR)/$(STATIC_LIB) $(LIB_DIR)/$(DYNAMIC_LIB)clean:    $(RM) $(STATIC_OBJ_DIR)/*.o $(DYNAMIC_OBJ_DIR)/*.o

 

3、执行 make 和 make LIBTYPE=static 后的目录结构

[root@localhost libname]# tree.+-- include¦   +-- headerA.h¦   +-- headerB.h+-- lib¦   +-- libname.a¦   +-- libname.so+-- lib_obj¦   +-- dynamic_obj¦   ¦   +-- cppsrcA.o¦   ¦   +-- cppsrcB.o¦   ¦   +-- csrcA.o¦   ¦   +-- csrcB.o¦   +-- static_obj¦       +-- cppsrcA.o¦       +-- cppsrcB.o¦       +-- csrcA.o¦       +-- csrcB.o+-- Makefile+-- src¦   +-- cppsrcA.cpp¦   +-- cppsrcB.cpp¦   +-- csrcA.c¦   +-- csrcB.c+-- test7 directories, 17 files
