Assuming you did so, how did you manage to build for armv7?

The steps are the same as what you did when you built for armv7 and you're just selecting a different architecture.

Moving this thread to the Gentoo forum to give your issue better visibility for the Gentoo distribution.

Meanwhile you should review what you did to build for armv7 and then follow the same process, but select a different CPU architecture.

The fact is that armv7-32bit. armv8-64bit The compiler that is available in armv7 refuses to compile the armv8 system.

the main thing is that there is no stage armv8. need to recompile armv7 under 64bit. but armv7 is 32bit

You need to configure the cross compiler for the correct target. If you are using a native compiler on an armv7 and not configuring it to cross compile, then exactly what you say is true.

Better instead to see if you have an x86 target with the Linaro toolkit and see if you can make a proper cross compilation configuration for armv8.

What did you do to compile your distro for armv7 before?

it's a long story collected u-boot. prepared sd card, created a partition, formatted it, recorded u-boot, downloaded portage, downloaded stage armv7 all unpacked took the kernel from armbian put it in the boot took modules. well, that was collected. thanks for the help, what happened to gather Gentoo is the merit of all forums and forum users. helped all countries) Russia, USA , China... everyone helped. Okay, I'm gonna go try to build on that.
