[gentoo-user] make.conf ambiguity - i486 or i686
I am in the middle of re-attempting an installation after my first two attempts froze. I have just completed an emerge sync, and I'm giving the /etc/make.conf file a once-over before I go. Question. Apologies if this is a FAQ. Google doesn't provide a clear answer... In the CHOST section at the top, my default value (before entering stage 1) is i486-pc-linux-gnu. In reading the comments, it says to leave this alone for a Pentium Pro or higher processor. My P4 is indeed = PPro. However, then it says that any modern machine should use i686. Later on, in CFLAGS, the file has an -mCPU=i686 declaration. So which is it? Should I leave it at i486 and proceed with stage1, or change it to i686? Should I leave it alone for stage1, then go back and change it for stage2? Jason Newquist San Francisco Bay Area -- [EMAIL PROTECTED] mailing list

A 486 is NOT a modern machine in this context.

I have a PPro... (586-200mHX) as my gentoo firewall. I use:
CHOST=i586-pc-linux-gnu
CFLAGS=-mcpu=i586 -O2 -pipe
CXXFLAGS=${CFLAGS}
If you have a 486, I believe you are a pentium (NOT a pentium pro). I
would change all the i586's above to i486s.
You definitely do NOT want to compile with -mcpu=i686
It will generate code that will not work. I think that is true for
-mcpu=i586 as well... but I may be wrong. Play it safe, though.

So which is it? Should I leave it at i486 and proceed with stage1,
or change it to i686? Should I leave it alone for stage1, then go
back and change it for stage2?
Set them properly first.
My P4 uses:
CHOST=i686-pc-linux-gnu
CFLAGS=-Os -march=pentium3 -pipe # does pentium4 work right yet?
CXXFLAGS=${CFLAGS}

-march=pentium4 should work fine now with both arch and ~arch versions
of gcc.
