我在尝试使用我的 makefile 运行 我的代码时遇到此错误：

我的 makefile 代码：

find_bits.o: find_bits.c
gcc -g -ansi -pedantic -Wall find_bits.c -o find_bits.o

我搜索了这个问题的解决方案，但似乎没有找到与我遇到的问题完全相同的解决方案。
我对使用 C 进行编码也很陌生，所以如果我的错误是我不应该用该语言的一些常识了解的错误，我很抱歉打扰你我的问题。
您应该添加 -c 选项来创建目标文件而不是可执行二进制文件。
find_bits.o: find_bits.c
gcc -c -g -ansi -pedantic -Wall find_bits.c -o find_bits.o
这个make规则...
find_bits.o: find_bits.c
gcc -g -ansi -pedantic -Wall find_bits.c -o find_bits.o
... 构建并 link 一个名为 find_bits.o 的 程序。那么这条规则...
open_bits: find_bits.o
gcc -g -ansi -pedantic -Wall find_bits.o -o open_bits
... 要求程序 find_bits.o 像目标文件一样被 link 编辑，以形成程序 open_bits.
使用 -c 选项编译为目标文件，而无需继续 link 结果：
CFLAGS = -g -ansi -pedantic -Wall
open_bits: find_bits.o
gcc $(CFLAGS) $^ -o $@
