Feature Request: aarch64-unknown-linux-gnu generic prebuilt binaries

[pullipulli]

I tried compiling directly from my linux server and the resulting binary gives me the following error when executed:
[1] 2734380 illegal hardware instruction (core dumped) ./lore

That means that in some way lore rust code does not translate in legal instructions for aarch64-unknown-linux-gnu.

Maybe a prebuilt binary from you can solve this issue? I also tried to use the neoverse-512tvb archive but the same error appears.

I think it is important to have the possibility to use lore from aarch64 linux.

This is a known issue, we've got plans to add a generic aarch64 build to the releases, the current one is Graviton only as thats what we run for our servers. If you want to build it yourself you can locally modify .cargo/config.toml to remove the neoverse flag then build.

Thank you for the answer.
Unfortunately, even if I remove from the config file the neoverse flag, the executable gives me the same exact error as before.

@pullipulli You will also need to remove

if platform == "linux" && arch == "aarch64" {
        cc_builder.flag("-mcpu=neoverse-512tvb");
    }

from https://github.com/EpicGames/lore/blob/main/lore-base/build.rs

I just got a generic Linux build working on my NAS after editing both build.rs and config.toml

@james-e-kelly THANK YOU! It gives me some warnings when I compile, but at least it works!
