Old stage3 tarballs

[akrmn24]

I'm looking for a historical archive of stage3 tarballs, in particular, the oldest available for ARM64/MUSL.

Thanks

[akrmn24]

Basically want to bootstrap my system from a smaller binary seed. I think the main options are TCC (I have trouble compling gmake with this on ARM64) or an older version of GCC. So far I have GCC 4.9 building in this tarball: https://gentoo.osuosl.org/experimental/arm/uclibc/stage3-armv7a_hardfp-uclibc-vanilla-20181008.tar.bz2

But if there's better ideas, you can let me know

What is your vision of your smallest tarball(image) capability?

further use it to build a desktop? create a router? for IoT?

alpinelinux rootfs is very small does it not do what you want? Or just want to see how small you can build a rootfs?

Even smallest image need a definition of what its capability. Are you trying to build a smaller rootfs than alpnielinux?

akrmn24,

Make your own seed. For a one off,

[akrmn24]

By binary seed I mean the toolchain (compiler, binutils, libc) and busybox. Starting from this (and a bunch of source code) I want to build a modern system capable of running a modern browser and other things.

I think this does more or less what I want but for AMD64, not ARM64: https://github.com/ZilchOS/bootstrap-from-tcc

For amd64 I tried one of the recipes (gmake) and it worked, but for arm64 it gave many errors, which I can post in the ARM subforum later.

I think Alpine is a nice project but I never tried it so not sure if they have some scripts that can bootstrap as I want. I will look.

See https://github.com/fosslinux/live-bootstrap/
Officially, only x86 is supported, but you can pick ARM64 architecture.
Note that it bootstraps musl-libc instead of glibc, but it does bootstrap the world from just a machine code pre-processor.
There's also https://mid-kid.root.sx/git/mid-kid/bootstrap/src/branch/master/gentoo-2025 , which starts with live-boostrap x86 and then constructs amd64 gentoo out of it.

If you want to bootstrap openjdk or go, see https://gitlab.com/stikonas/gentoo-bootstrap , which you can enabled with eselect repository enable gentoo-bootstrap.

EDIT: Fixed the links.

Ya I've heard about live-bootrap before and now I'm looking into it again, but I just want to take some pieces from it, like the make-3.82 recipe they have in steps/. It doesn't seem to work for me on my ARM system. But also I don't understand what

akrmn24,

There is a comma at the end of the link that is not a part of the link. Hence 404.
It's quite common here

Indeed catm just concatenates files.

It is written because:
1. We don't have cat from coreutils early in the bootstrap.
2. cat also needs more advanced features like output redirection, e.g. "cat file1 file2 > combined". Our early shells (and kernels) in live-bootstrap don't support that, so "catm combined file1 file2" works.

Coincidentally, "catm config.h" craetes an empty file. On normal system you could achieve that using "touch config.h" or "> config.h".

Live-bootstrap doesn't work on arm64 mainly because GNU mes does not yet support it.

amd64 is not supported because mescc from GNU mes is a bit buggy and probably miscompiles tcc a bit. The first version of tcc can be built in live-bootstrap and it can compile some files but not enough to rebuild itself (segfaults on some files). So until this is fixed we are stuck there.

riscv64 version actually can run quite far but not everything is pushed into live-bootstrap master. The main problem is that a patch that fixes riscv64 support in bootstrappable fork of tcc breaks x86, this needs fixing properly (or we could apply patch conditionally). After that I've manually tried riscv64 bootstrap and was able to reach GCC9.
