What am I doing wrong here? 🙃

required (system, features): (riscv64-linux, )
4 available machines:
(systems, maxjobs, supportedFeatures, mandatoryFeatures)
# ...
#                          vvvvvvvvvvvvv
(x86_64-linux, i686-linux, riscv64-linux, 2, benchmark, big-parallel, kvm, nixos-test, )
#                          ^^^^^^^^^^^^^
error: unable to start any build; remote machines may not have all required system features.

yep. I've been trying to test it's set up properly on that remote machine, looks like it is

# downloaded rustc
$ ./rust-1.60.0-riscv64gc-unknown-linux-gnu/rustc/bin/rustc --help
qemu-riscv64: Could not open '/lib/ld-linux-riscv64-lp64d.so.1': No such file or directory

and

nix --extra-experimental-features "nix-command flakes" build .#packages.riscv64-linux.hello

looks good in htop

$ cat flake.nix
{
  outputs = { self, nixpkgs }: {
    packages.riscv64-linux.hello = nixpkgs.legacyPackages.riscv64-linux.hello;
  };
}

3 failed tests on bison

We have to use custom boot firmware since we do not support

StarFive's Fedora MMC partition layout. Thus, we include this in

the image's firmware partition so the user can flash the custom firmware.

anything I need to do here or will it be done automatically?

I'm just assuming this is an issue introduced by binfmt so I'm back to x86_64-linux cross compiling. currently on the kernel

Sounds like some good tests :)

I had a look into gnu autotest but I couldn't see an easy way to get some more useful debug logs :(

here's the shortlist of the failing tests:

2: Invalid number of arguments                       FAILED (input.at:29)
64: Deprecated directives                            FAILED (input.at:3031)
314: Invalid uses of %empty                          FAILED (actions.at:192)

it mentions some stuff about log outputs but I didn't go too deep on it

nix on fedora will do for now :D

to get the tarball I just added riscv as a cross target and I needed a newer copy of boost
