iniparser示例程序

下载iniparser，下载地址：http://blog.csdn.net/zahuopuboss/article/details/8817538

将iniparser源代码中src目录下的4个文件dictionary.c、dictionary.h、iniparser.c、iniparser.h和示例程序放到同一个目录下

使用下面的Makefile编译

 

##EXEC = initestCC= gccCFLAGS += -Wall -WerrorCFLAGS += -g -MD -O2CFLAGS += -fPIC -ansi -pedanticSRCS = $(wildcard *.c)OBJS = $(SRCS:%.c=obj/%.o)DEPS = $(SRCS:%.c=obj/%.d)all : $(EXEC)@:$(EXEC) : $(OBJS)$(CC) $(LDFLAGS) $^ -o $@obj/%.o : %.c@mkdir -p obj$(CC) $(CFLAGS) -c $< -o $@clean :rm -rf objsinclude $(DEPS).PHONY : all clean
