我用 --debug
对此进行了更多调查

由于头文件依赖性，make 认为它已经正确地重新制作目标文件目标，即使它没有看到源文件。
如果您提供源文件（即使是空文件），输出看起来会有点不同

在这里您可以看到，make 如何检查所有先决条件，然后使用 makefile 中给出的隐式规则重建目标文件。
您可以通过将源文件明确列为依赖项来避免 make 的混淆，例如
coder.o: coder.c
Make 将在不调用 link 命令的情况下抱怨缺少源文件

make: *** [coder] Error 1
编译器找不到目标文件，因为它们不是构建的。并且目标文件没有构建，因为源在不同的目录中（例如 src）或者由于其他原因 make 看不到它们。
我用 --debug
make --debug=v -f makefile.gcc
并获得

由于头文件依赖性，make 认为它已经正确地重新制作目标文件目标，即使它没有看到源文件。
如果您提供源文件（即使是空文件），输出看起来会有点不同

在这里您可以看到，make 如何检查所有先决条件，然后使用 makefile 中给出的隐式规则重建目标文件。
您可以通过将源文件明确列为依赖项来避免 make 的混淆，例如
coder.o: coder.c
Make 将在不调用 link 命令的情况下抱怨缺少源文件
make: *** No rule to make target `coder.c', needed by `coder.o'. Stop.
