我放置了几个依赖项，以便强制 make 仅在文件更改时进行编译。然而每次我运行时 make 都会编译所有内容。有没有办法可以修改它以仅编译已修改的文件？运行 make 将始终触发完全重新编译，即使没有任何更改。所有文件都没有改变，那么为什么要这样做呢？

Answer 1

是的。方法是按照 second rule of makefiles 进行操作。 .

您的规则规定您将构建一个文件，例如 gtk-connection.o。但规则中的配方实际上做是构建一个文件，例如main/classification/gtk-connection.o。你没有告诉 make 真相，因此下次运行 make 时，它​​会查看文件 gtk-connection.o 是否存在，但它永远不会存在，因此 make 总是决定重建它。

您需要更改规则的目标以反射(reflect)您想要构建的实际文件，或者您必须更改配方以构建您告诉 make 您要构建的文件。

一般来说，您确实应该尝试利用 make 的功能来简化 makefile，例如模式规则、自动变量等。
