[gentoo-dev] How to handle x86/amd64 only packages on other arches

[gentoo-dev] How to handle x86/amd64 only packages on other arches

[Doug Goldstein]

I need to be able to have ppc/arm/etc users install a package that can
only be built on x86/amd64. The packages in question are
sys-apps/seabios and sys-apps/vgabios. The point is that a PPC machine
that's using qemu-system-x86_64 still needs to use seabios and
vgabios. I was planning on building the package on my own hardware and
posting up sys-apps/seabios-bin and sys-apps/vgabios-bin unless of
course someone has a better suggestion.

I know the list tends to devolve into the theory of foo/bar and
foo/baz but I'd like to keep this concrete to those two packages.

Possibly a USE flag could be added to seabios/vgabios, similar to the
"fontforge" flag in font packages, enabled by default and masked in
profiles that don't support building from source.

It's the simplest thing to maintain. It eases binary package creation
and does not need any blockers, virtuals or conditional depends.

You just patch an ebuild, run `emerge --buildkpgonly seabios`
and package is ready. All in one place.

Sample patch with USE=binary attached.

Re: [gentoo-dev] How to handle x86/amd64 only packages on other arches

[Xavier Miller]

Hello,

Thank you very much for your replies :)

Doubling the timeout seems to work (no error so far, the SHDHC card is
fully useable).

I disabled the MMC debugging, and I also see that, grepping mmc in dmesg:
[    2.795410] _regulator_get: omap_hsmmc.0 supply vmmc_aux not found,
using dummy regulator
[    2.806335] _regulator_get: omap_hsmmc.4 supply vmmc_aux not found,
using dummy regulator

Is it normal?

Kind regards,
Xavier.

You know, if you replied in context instead of "upside down" (reply above 
quote, quote appended verbatim), you'd have probably noticed that you 
were replying to the wrong post on the wrong list!

Just sayin...

Yes, -bin seem to be the best solution. Otherwise, we'd have to require
some kind of portage-capable cross-toolchain for that package.

I'd suggest you *DEPEND on it through:
	|| ( sys-apps/seabios sys-apps/seabios-bin )

so that x86 users could still choose the binary package for some reason.
