Hi

I am unable to build box86 from the guru repository. box64 works just fine.

emerge --info app-emulation/box86

vimja,

Code: Select all

aarch64-unknown-linux-gnu-gcc: error: unrecognized command-line option ‘-m32’

On a multilib system, -m32 tells gcc to emit 32 bit code.

There is no multilib in the aarch64 world, so building for 32 bit is not supported.

Its possible to run a 32 bit userland on top of a 64 bit arm kernel, but there is no mixing 32 and 64 bit code.

The arm 32 bit instruction set is optional in aarch64 silicon. Not all aarch64 CPUs can run 32 bit code.

Moved from Portage & Programming to Gentoo on ARM.

Ampere is an arm system

That makes total sense. Somehow I just expected box86 to make x86 work on 64bit ARM. But now that I've read the the box86 documentation, they make it very clear this is not the case.

My bad, sorry about that.

Hello vimja!! I'm the box* ebuild maintainer in guru.

Yes, box86 requires a compiler capable of emitting 32 bit code, and also relies on having a valid libc in `/lib`. Negril recently brought to my attention that multilib profiles aren't much of a thing for non x86 architectures, but for the devoted there's a few solutions.

The most 'correct' way I am aware of (and someone here can correct me if I'm wrong) is to make a custom profile and use it. It probably isn't *that* hard and I've been meaning to give it a shot, but haven't yet.

The way I do it personally (easy way) is to install the 32 bit version of your architecture in crossdev ( see crossdev's page on our wiki ) and then follow sam's instructions (here)[https://gist.github.com/thesamesam/f434 ... b0befbe21f]. Then, `cp -r /usr/$(CHOST)/lib /lib && ln -s /usr/$(CHOST)/lib /lib`, then set the CC and CXX to the crossdev installed toolchains in package.env. This is a pretty suboptimal way, and ___DO NOT REMOVE/UNINSTALL THE CROSSDEV INSTANCE WITHOUT UNSETTING THE SYMLINK___. For box86, you don't actually need to set any symlinks as its only dependency is libc, but if you plan to be running 32bit code on your system it'd be nice to have an easy way to install 32bit libs on your system.

I'm going to be submitting some commits to improve the 64bit support in box86's ebuild, with a more helpful error message.

Also: bugzilla reports are nice because I'm automatically emailed, I will not be aware of any forum posts unless you reach out to me. Please ping me on IRC (rrogalski on libera and oftc) or send me an email (current one found in metadata.xml) for any forum posts regarding box or any other packages I maintain

P.S: yes I know the box* versions are slightly old, last time I tried revbumping I ran into a test regression on ppcle, when the fix is in a tagged release I'll update it[/url]
