Hi everybody,

If I have correctly understand, it is not possible to install Gentoo on
a 386 ...
If am right, do you think it possible to extract my hard disk, put it in
a newer machine,
recompile everything for a 386 and put it back in my old PC ?
In fact, I have a Debian on this machine, but now, packages contains 486
instructions (thanks to gcc 3.2) ...

Thanks

Olivier

Yeah, you should be able to compile everything on another system and
then transplant those binaries to your 386. It's still going to run
really slow though.

Why is that?

Thx,

Stages (for generic x86) are compiled with CHOST=i486-pc-linux-gnu.

I don't think that it is that you can't, it is probably more along the
lines of why would you want to? It may not be that bad starting from
Stage 3 or even Stage 2, but to start from Stage 1, you would be facing
horrendous compile times.

Just for weight of comparision, the bootstrap alone took 17 hours on my
old AMD K6 450 w/ 512 Meg o' RAM. All in all, it took me an entire
weekend to get to a Stage 3 machine, and then the rest of the week to
get the rest of my apps up (X, Fluxbox, xmms, etc). Unless you're a
complete glutton for punishment, have a lot of spare time, or just
really feel like doing it for the experience, I'd try to steer towards a
binary distribution.

Good luck and let us know how it turns out!

Ok. Show me the i386 stage3!

-grin- No can do. As Mr. Portnoy pointed out, the stages for x86 are
compiled for 486 - a piece of info that I didn't have at the time of
posting. Have fun compiling for the next 3 weeks!

Yep... some 1.4_rc1 or rc2 was the place where that was shifted to i486
stage1...

I cursed a lot!

....wanted to get the stages ready and c++ thought compiling for 386 would
be cross-compiling...

:-/

Still having nightmares thinking back approximately 1 year...


....but that means: if you find some 1.4_beta (or a late 1.3) directory on
some server, you might have a stage3 that works for i386...

How will a current g++ behave if compiled on 386 directly?

I'd love to try it but my smallest system is an amd5x86wb@133 (a late
486 clone)... I am that crazy! ;-)

Thanks for the info.
Don't worry about the compile time, my 386 is overclocked !
And with 2.6-test8, it runs at light speed !

If Olivier has another, faster machine in the LAN, he could use distcc
to compile on it, instead of using the i386. The setup is quite easy,
it is described here: http://www.gentoo.org/doc/en/distcc.xml
I just set up Gentoo on a laptop, using distcc after bootstrapping to
speed things up a lot.

http://www.bisso.com/ujg_archives/000227.html has some info on this.
