I think the solana compiler comes with a rustc. And I use solana-cli 1.8 to compile and don't have any issues.

same error, I also tried with rustc 1.57.0-nightly (2021-09-07) same error. What wrong with me?

[microwavedcola1]

@thanhngvpt @buffalu are you guys using rosetta compatibility mode? m1 is my main driver, and havent had any issues so far

[RohanKapurDEV]

havent had any issues building on m1 either

[sthornington]

The root cause of this is that mango (and switchboard) have #[repr(C)] for some account data structs (SwitchboardDecimal, *Node in matching.rs and *Event in queue.rs), but on ARM, the alignment of i128 is 16 bytes, vs 8 bytes for x86_64. These structs should all be #[repr(packed)] in my opinion, as they are in the serum dex examples.

[sthornington]

In fact, it looks like SwitchboardDecimal is already packed in the latest...

[sthornington]

@ckamm did you have any luck upgrading switchboard? I see you pinned the versions to older ones fairly recently...

[ckamm]

Upgrading switchboard wasn't a priority so I haven't looked at it further. This PR has an upgrade though: #150

[sthornington]

Gotcha. Yeah I haven’t gotten further enough to see whether switching all the account state structs to repr(packed) fixes everything else. I suspect one day everyone will be forced to switch to proper serdes using borsh rather than bytemuck casting.

I ran into the same issue, and I was able to rectify the issue with rustup by switching the active tool-chain.

You can confirm by running: rustup show. If you see stable-x86_64-apple-darwin (default) under active toolchain, you're good to go.

Otherwise, do as follows:

rustup default stable-x86_64-apple-darwin

Try it out:

cargo build

You should be able to build without any platform specific issues now.

[sthornington]

Yes of course you can fix an issue with bad alignment on ARM by not compiling on ARM. 😀

I've got the same issue with Ubuntu 20.04
