GCC：未定义的引用（Makefile问题）

尝试使用gcc在Makefile规则下编译这些文件。在cygwin上运行gcc/make。GCC：未定义的引用（Makefile问题）

这里的生成文件：

CC = gcc 
CFLAGS = -g -O2 -Wall -std=c99 
OBJECTS = simulation.o element.o 

simulation.exe : $(OBJECTS) 
    $(CC) $(CFLAGS) -o simulation.exe $(OBJECTS) 

simulation.o : file_priorite.o element.o 
    $(CC) $(CFLAGS) -c simulation.c 

file_priorite.o: file_priorite.h element.o 
    $(CC) $(CFLAGS) -c file_priorite.c 

element.o : element.h 
    $(CC) $(CFLAGS) -c element.c 

clean: 
    rm -f *.o simulation.exe

遇到这些错误：

有问题的功能在file_priorite.c全部实现。

有什么想法？

你没有链接到file_priorite.o（并且它没有被创建，因为你没有把它放在OBJECTS中） – 2014-11-24 17:35:56

扩展@ remyabel的评论。查看你在文件中列出'element.o'的地方以及列出'file_priorite.o'的地方。 – 2014-11-24 17:37:00

请注意，您构建的日志不包括以任何形式file_priorite - 这意味着你没有建立/链接反对。将file_priorite.o添加到您的OBJECTS系列。

我知道这真的很愚蠢。人为错误，woops。谢谢，我会尽快接受你的回答。 – slaughterize 2014-11-24 17:37:49

你需要有

OBJECTS = simulation.o element.o file_priorite.o
