make.conf and make.globals

I've set CFLAGS="-march=pentium3 -O3 -pipe" and CXXFLAGS="${CFLAGS}" in make.conf.

Now when I compile something it mostly does not use those CFLAGS. It uses the ones from make.globals! (They're set "-O2 -mcpu686 -pipe" per default). In make.globals its explicitely said "WARNING DO NOT EDIT THIS FILE, changes to make.conf override this file."

eg: I'm currently recompiling my kernel (gentoo-gaming). It says "gcc -D__KERNEL [...] (and so on) -Wall -O2 -march=i686 [...]"
Why does it not compile with my CFLAGS set in make.conf ??
And eg

apps can override your settings and specify what it thinks are safer CFLAGS.

the kernel is one such "app".

there is a way to override it, but I can't remember how.

search specifically for kernel and flags... I remember seeing it here a number of months ago

so don't worry it's entirely normal

Wouldn't it be better (faster) If we could compile the kernel with march=pentium4 instead of just default mcpu=i686 ? Why isn't this possible without some "trick"?

Why shouldn't we edit the make.globals file?

Then I don't see the purpose of this make.conf anymore, most of my apps DO override this settings and use their own (slower) standard flags.

make.globals is overwritten every time you emerge sync

and the kernel compiles with the most stable FLAGS while providing the best performance.

u can compile your kernel with -march=pentium4 but you will prob find your system crashing for no particular reason.

but try it.

the only apps that I know of that overwride your make.conf are kernel, and openoffice.

most others I think adhear to your make.conf.

also if u stop the bootstrap process and start again it overwrites your make.con (it makes a backup and then copies it back .. at least it used to)

why don't u post your make.conf? I can have a look.. not that that is the problem here.. but u know..[/u]
