Subject: | "generating prerequisites automatically" causes all *.d makefiles to be regenerated? |

Hello, There seems to be a problem however with this
approach. I write “seems” because it must be that I don’t
understand something, as I am sure the GNU Make manual recommends the “right
thing”. Please help me understand what I am missing. The problem I have is: when I do >make foobar.o make then tries to generate all these *.d files, all of them
– not just the one that is needed foobar.d ! That is not good –takes
a lot of time if I just want one foobar.o. Also, what is worse, if I do >make clean Then again, all the *.d files are generated first, takes a
very long time, before everything is deleted. How to do it so that only the *.d files that are really
needed are generated, and none are generated on make clean? Thank you for any insight, Mark |
