 |
|
I've started using the 2.5.70-r3 sources and ahve a coulpe questions about terminology and compiling.
terminology:
are 2.5.70-r3 and 2.5.70-mm3 the same thing? I see the mm3 thing outside this forum a lot and was woundering if there was a difference?
compiling:
I saw the post about not needing 'make dep' now, but I have noticed that if I do not do a 'make clean' theses sources recompile a lot quicker. When is it advisable/important to do a 'make clean' before 'make bzImage modules modules_install'
Thx in advance,
wallace |

| Make clean is going to delete all the object files from previous compiles. This means that when you recompile it will be a full recompile. The appeal of using make is that you don't have to do this. Make knows which files are different so it can recompile those needed and not the whole thing. |

I'm not familiar enough with the kernel make process to know if it doesn't link files not in the config. If it doesn't link them then it doesn't matter because your kernel size won't change because of make clean. If it links all the object code then make clean would affect kernel size. |
