我确信我在这个makefile中做事情的方式有很多问题(主要集中在我主要在所有命令中使用"文件列表"这一事实，而不是内置的自动变量($^等)。它按原样构建目标，但我遇到的主要问题是，它重新编译了所有先决条件，而不仅仅是那些自上次构建以来发生了更改的先决条件。我想把它转换为使用自动变量的先决条件，而不是我目前使用的"变量文件列表"方法(即$(SOURCES))。我也很乐意听到您在上述makefile中看到的任何其他问题!
我正在使用MINGW make，但我希望makefile可以在GNU, NMAKE等之间移植。
edit:输出如下所示(更改了一个文件- adc.c，您可以看到所有内容都被重新构建了…)

基本问题是这样的规则:
$(SOURCESS) : $(SOURCES)
$(CC) $(CFLAGS) $(SOURCES)
因此 SOURCES的所有成员是 SOURCESS的所有成员的先决条件;更改一个文件，例如vector.c, Make认为所有的目标(MAIN.s vector.s can.s allegro3930.s regulatorctrl.s timer.s adc.s)都过期了，需要重新构建。
我建议一个更严格的规则，就像这样:
%.s : %.c
$(CC) $(CFLAGS) $<
请注意这可能不像写的那样工作，因为您使用的是MINGW Make，并且您在一个源文件中使用"。c"，而在其他源文件中使用"。c"(我相信您有您的原因)。你还在玩汇编程序。所以我不能测试这个解决方案，我只能指出问题
