I'm installing Gentoo on an Acer Aspire 110. It's one of the
"netbook" laptops. /etc/make.conf says:

CHOST="i486-pc-linux-gnu"

Is that correct?

If it's an Intel-compatible (x86) and Gentoo is 32-bit, then yes, that's
correct.

OK, does i686 indicate 64-bit?

No. 64-bit is "x86_64-pc-linux-gnu". I don't know why you have i486
instead of i686, but I do know that i486 is correct too. If it has any
drawbacks compared to i686, no idea.

This thread has gotten confusing. If you mean the Acer Aspire One
netbook (of which the A110 is a sub-model) then it uses an Intel Atom
N270 processor.


http://en.wikipedia.org/wiki/Aspire_One


It appears to be i686 & Gentoo wiki alleges the safe CFLAGS thusly:
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel#Atom_N270

(This took me 2 minutes on Google).

Stroller.

Hi,

It looks like you've probably used the "x86" stage3 tarball instead of
the "i686" one. While you can change it [0], the best option is probably
to start again using the correct tarball.


Note that if you do want to change CHOST, you _MUST_ follow the guide[0]
or you will end up with problems.

Thanks a lot, I read somewhere that I should not change my CHOST so I
was trying to figure out what was going on as opposed to figuring out
how to change it.

Is there any drawback from an i486 CHOST when -march settings indicate
an i686? Does it produce slower code?
