chroot: failed to run command ‘/bin/bash’: Exec format error about build

[github-actions]

Jira ticket: AR-1896

[igorpecovnik]

Riscv64 support is overall not yet in the best shape but using unsupported build host is just asking for troubles. I am not familiar with how Solus is different from Debian / Ubuntu so its difficult to say, but I was not able to reproduce on officially supported Jammy build host:

./compile.sh build BOARD=licheepi-4a BRANCH=legacy BUILD_DESKTOP=no BUILD_MINIMAL=yes KERNEL_CONFIGURE=yes RELEASE=jammy SHARE_LOG=yes
https://paste.next.armbian.com/rilutepeta

As I don't have hardware nor time to check, I don't know if resulted image boots.

More things are missing too:

--> (3) COMMAND: update-binfmts --enable qemu-arm bash: line 1: update-binfmts: command not found

this is again binfmt / qemu stuff which is host-dependent.

Thanks for your patient reply. I missed install package binfmt-support. After I installed binfmt-support package, now there have update-binfmts now.

yeah, and after I install binfmt-support from source , now I can do command with update-binfmts. But when I try do command with update-binfmts --enable qemu-arm I get these errors:

▸ sudo update-binfmts --enable qemu-riscv64
[sudo] password for yangyongsheng:
update-binfmts: warning: qemu-riscv64not in database of installed binary formats.
update-binfmts: exiting due to previous errors

After I google this, then I do command with sudo update-binfmts --install qemu-riscv64 /bin/qemu-riscv64 --magic '\x7f\x45\x4c\x46\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00' to register qemu-riscv64 support. Then After I do command sudo update-binfmts --enable qemu-riscv64, something terrible happened as:

the host OS is broken, I must repower the laptop. is there anything wrong? thanks in advance.

[igorpecovnik]

is there anything wrong?

Nothing is wrong with our builds tools apparently. As it works for us and in CI. We can't reproduce, we don't have resources to work on task that is officially rejected - supporting "all" Linux distributions as a build host. There are many many real support problems elsewhere ...

This can not be recognized as an issue.

I hope you accept this with understanding.

Yeah, After I solve the problems with binfmt-support package, now I can build the image under Solus, but not checked 😅 .
What I do just rebuild qemu with -static flag refer to https://gitlab.archlinux.org/archlinux/packaging/packages/qemu. Then I move qemu-riscv64/arm/aarch64-static to /usr/bin directory and use commands with:

sudo update-binfmts --install qemu-riscv64 /usr/bin/qemu-riscv64-static --magic '\x7f\x45\x4c\x46\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\xf3\x00' --mask '\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff'


sudo update-binfmts --install qemu-aarch64 /usr/bin/qemu-aarch64-static --magic '\x7f\x45\x4c\x46\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\xb7\x00' --mask '\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff'


sudo update-binfmts --install qemu-arm /usr/bin/qemu-arm-static --magic '\x7f\x45\x4c\x46\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00' --mask '\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff'

to registe these arch releate interpreter。Besides I get these magic and mask form package https://packages.debian.org/sid/qemu-user-static，a file named binfmt-install list these magic and mask. Then I use command below test success.
