Re: [discuss] Problem building cross compiler for x86_64

Mike, Kai's intent might be a bit unclear owing to the language barrier, and

he's talking about, and he does have a pretty important point to make: that,
if you already have a prebuilt binary glibc for your target, building a new
one from source is not just a waste of time, but potentially a source of bugs
or very subtle and hard-to-track incompatibilities, since it might not come
out /quite/ the same as the old one. This issue is very important for people
working with standard engineering practices that emphasis stability,
reliability and careful management of change control.



If it is a subtle source of bugs, then there's something really, really broken somewhere.


The rebuilt cross-glibc would be built with the same cross compiler used to build the toolchain's glibc. Ergo, if gcc can't codegen it the same way twice in a row something is _really_ wrong.

I'm guessing that kind of breakage wouldn't be subtle at all. :)
