Re: [gentoo-user] 1.4_final CFLAGS Generation?

[Riyad Kalla]

They might be referring to the genflags package, it comes with strangely 
names info2flags, info2host and host2flags. It parses your machine 
information and spits back safe/fast flags for you. Kind of a middle 
ground. Not freakishly optimized, but also not going to cause you to 
segfault at strange times.

An example from a run-of-the-mill P4 Dell machine:
<hostname> root # info2host
MAINARCH="x86"
SUBARCH="pentium4"
<hostname> root # info2flags
CHOST="i686-unknown-gnu-linux"
CFLAGS="-march=pentium4 -O3 -pipe"
CXXFLAGS="-march=pentium4 -O3 -pipe"
An example from a dual P4 XEON server (Dell again):
<hostname> root # info2host
MAINARCH="x86"
SUBARCH="xeon"
<hostname> root # info2flags
CHOST="i686-unknown-gnu-linux"
CFLAGS="-march=pentium4 -O3 -pipe"
CXXFLAGS="-march=pentium4 -O3 -pipe"
Best,

I'm bootstrapping 1.4 as we speak, and I didn't see any signs of "CFLAG generation".

I'm just wondering.  This is the announcement from www.gentoo.org: "1.4
includes automated kernel  builds, CFLAGS generation, the Gentoo Reference
Platform, and support  for netless installation."
Where/how is/do you do the CFLAGS generation!?
