according to musl's say, it is lightweighted lib, why there no musl + 486/586 combination?

youxiaojie,

It may work but it's unlikely anyone has tested it.
A lot of things are like that.
Someone has to be first ... is it your turn?

If you try it, be sure to share your results.

I hope to try, but I don't know the step:( I did it according to the guide, especially stage3, there is no place to download. do you like to give some advice?

I'm not sure if there will be a stage3 ... [bug]803854[/bug]

Your best bet is to start with a musl stage3 on a regular i686/amd64 and rebuild @world with i486 cflags/chost. I think the i686 compiler will build i486 binaries just fine, just a matter of building everything without i686 instructions. Then move the disk over to the real i486.

Beware the resulting system will be very slow, slower than one would expect... A lot of the features used in i686 has very poor i486 workarounds. I have a K6-233 that I use i486 glibc and some of the X stuff is painfully slow...

eccerr0r,

That's a good place to start but it will leave the 486 with a 686 toolchain.
To make it 486 'pure', the CHOST needs to be changed, which means running the bootstrap.sh script, if it's still there.

It may not matter, since the 486 will not have enough real RAM to build anything.

Looks like there's no audience left?

Someone who cares should comment indicating they care, we have no way of knowing otherwise.

youxiaojie and anyone else should comment on that bug if you're interested in Gentoo providing a musl 486 stage3. Seems like a good idea IMHO but I'm about out of 486's... I'm sort of kicking myself selling my 486dx4/100 board...
