RE: [Xen-devel] latest make world

[James Harper <JamesH@xxxxxxxxxxxxxxxx>]

Now that you mention it, i have noticed this in standard kernel compiles in 2.4, but I haven't built a 2.4 kernel in a long time so i'd forgotten :)

 

2.6 is indeed much better. How long do we have to wait :)

> hmmm... i didn't check install/lib/modules/... but make install took quite a while, and was definitely compiling modules. is it possible that make install could be recompiling them?

The linux build system is pretty broken and during the build
process it touches something which causes it to think certain
files need to be rebuilt next time round. It takes a couple of
builds before it reaches a fixed point. "make install" checks
that everything is up to date, which does cause some parts of the
linux tree to needlessly rebuild. The 2.6 build system is
supposed to be rather more sane in this respect...

Not our bug, honest ;-)
