Gentoo/Portage support for mips

[manphiz]

It looks like some time ago the mips support for portage was removed as there is no mips column in ebuild status. However the Gentoo mips install guide is still available. I wonder what's the status of the current Gentoo/Portage support on mips? Is it still possible to use the current portage on such systems?

Why do you say mips was removed? It doesn't look like there's "stable" mips, but plenty of packages have ~mips keywords and there's recent mips-related activity in the portage tree:

Code: Select all

/var/db/repos/gentoo $ git log --grep mips

Thanks Etal! It's just that if I visit the package page of dev-libs/apr[1] mips is not listed in the available versions which gives me the impression that mips is not supported. Good to know it's not the case!

BTW if the ebuild info page is missing mips info, is it a bug?

manphiz,

Maybe its a bug but not in portage. However,

Code: Select all

KEYWORDS="~alpha amd64 arm arm64 ~hppa ~ia64 ~mips ppc ppc64 ~riscv ~s390 sparc x86 ~x64-cygwin ~amd64-linux ~x86-linux ~ppc-macos ~x64-macos ~sparc-solaris ~sparc64-solaris ~x64-solaris ~x86-solaris"

~mips is listed.

Try

Code: Select all

qgrep -l mips

to list packages with mips or ~mips KEYWORDS.

Unkeyworded packages are untested on mips, not always broken. Someone has to be first testing, why not you.

I am just upgrading from the 2014 stage3 image to current snapshot. hehe

@manphiz on what MIPS hardware are you running Gentoo?
I have one surveillance camera that has MIPS CPU and it is running Linux. I have full root access to it and would really like to have portage at least in it. I hope I could have full Gentoo system there, but first I need to grab (backup) all the modules (if closed source) and possibly kernel too.

XiaoaiX,

You probably don't want to do that on MIPS hardware.
That leaves you with two paths.

Install a suitable MIPS toolchain on a more capable system then cross compile whatever your need.
That's easier said than done. Lots of things just work. Some need to be coaxed and others are cross compile hostile.

If QEMU supports your CPU, build QEMU with static-user, untar the 2014 stage into a directory on a more capable non MIPS system, install the QEMU-static and chroot into the MIPS stage 3. Now update there.
