It would be nice to add AArch64 (arm64) support in mutltilib-build eclass (and profiles) to also support multilib on arm64 systems.
Last I asked, nobody has seen a use case for multilib there.
Not all arm64 hardware can support multilib as the arm32 instruction set is optional on arm64.
https://patchwork.openembedded.org/patch/106801/ no however ARM32 can be added in kernel https://github.com/sakaki-/gentoo-on-rpi-64bit has it , and trying to merge most of which on to pinebook pro /rock64pro and rpi4 for now rpi3/rpo64 ... {pinebookpro/rpi4 in my cart....come payday} chroot can be on gentoo-on-rpi-64bit arm7hf , and will work.. simple golang bins work.. or in mudler's docker-companion building for aaarch64 meh.. getting arm bin from his github works. not needing chroot for arm7hf bins also a nice to have , multilib can be rigged from crossdev ?sometimes if host AMD-64 is by quirk, however its a fluke and on a few older bin-tarballs i have stashed. and seems occasionally one-off-ish. porthole after doing crossdev pass could sometimes get the rebuild... too.. however it could just have been for native-to-arch on my laptop. just qemu and gentoo and dockerhub make not for fun times with aarch64 , so having more native builds or less need of crossdev arm-host to arm-target/s also useful. as one could make easier cross wappers to do thus. one GCC-mutilib to rule them all --perhaps.. trying to build a few Secops tools the mutilib die ... was quite a thing.. making for not much fun sometime back.. metasploit it can be a killjoy.. but many SIEM packages , gentoo/pentoo net-anylyzer many want mutilib config last i tired. a few SIEM producs also not so much, sys-kernel/gentoo-kernel make allmodconfig + make allyesconfig + make menuconfig or grep out depreicated sys-fs and a few shite opts.. but beats banging on make menu..for hours (sed/repalce gentoo-kernel.bad/opts to do) gets all modules and yesss, depricated sys-fs-2 die.. twerk a few options above didnt get or if gentoo emerge net-something grips about opt. aufs5 zfs builtin etc etc.. https://gitgud.io/cloveros/cloveros/blob/master/kernel_build.sh (aufs5) patch... https://github.com/alexdux/async-emerge/tree/master/src/async-emerge-1.7 makes a docker-ish chroot in zswap/swap ram tmpfs, /packages , useful as it gets around circle-of-deeps hell.. binpkgs >> /packages if only better overlay-fs ... /grumble /grumble.. USE="mutilib" ae_makeworld pray mutilib goes. anyway a config of some sort for aarch64 sys-kernel/gentoo-kernel I chose one config , to rule them all. and ie if live aarch64 dvd like debian's or netboot having less
I still don't have a use case for this.
