Makefile文件和＆QUOT;搬迁具有无效的符号索引＆QUOT;错误 [英] Makefile and "relocation has invalid symbol index" error
问题描述
我试图写我的第一个Makefile文件。在项目中，我有这些文件：
I was trying to write my first makefile. In my project I have these files:
- 的main.c
- list.c
- list.h
- 的Makefile
有甚至没有函数定义或声明的任何人，只是简单的包括list.h和清洁的主要测试编译过程。当我编译这些文件在控制台命令：
There is even no function definition or declaration in any of them, just simple include "list.h" and clean main to test the compilation process. When I compile these files in console with command:
的gcc -std = C99 -Wall -Wextra的main.c list.c
一切都很好，但是当我用我的Makefile（Qt Creator中和国美终端）我得到了很多类似的错误：
everything is fine, but when I use my Makefile (in Qt Creator and Gome terminal) I'm getting a lot of errors like:
： - 1：错误：/usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info）：搬迁0具有无效符号索引11 。
这是我的Makefile：
This is my Makefile:
CC=gcc
CFLAGS=-std=c99 -Wall -Wextra
LDFLAGS=
all: listtest
listtest: main.o list.o
$(CC) main.o list.o -o listtest
main.o: main.c
$(CC) $(CFLAGS) main.c
list.o: list.c
$(CC) $(CFLAGS) list.c
clean:
rm -rf *o listtest
这是我使用去创造一个makefile教程。有什么不对这个makefile，我该如何解决？
This is a makefile tutorial I was using to create it. What's wrong with this makefile and how can I fix it?

推荐答案
您错过了 -c 在的.o 规则：
main.o: main.c
$(CC) -c -o main.o $(CFLAGS) main.c
list.o: list.c
$(CC) -c -o list.o $(CFLAGS) list.c
一个更好的规则是：
%.o : %.c
$(CC) -c $(CPPFLAGS) $(CFLAGS) -o $@ $<
此模式规则本质上是建立在内置规则的.o 从 .C ，见<一HREF =http://www.gnu.org/software/make/manual/make.html#Catalogue-of-Rules相对=nofollow>隐规则make的目录的。换句话说，你不需要编写任何上述规则。
This pattern rule is essentially the built-in rule for building .o from .c, see make's Catalogue of Implicit Rules. In other words, you don't need to write any of the above rules.
有一个更好的规则是：
%.o : %.c
$(CC) -c $(CPPFLAGS) $(CFLAGS) -o $@ -MD -MP -MF ${@:.o=.d} $<
这将自动为您生成依赖关系。这些依赖关系必须被纳入生成文件（在随后的运行中）：
This automatically generates dependencies for you. These dependencies need to be included into makefile (on subsequent runs):
-include $(wildcard *.d)
