Brian Hicks (Jan 03 2024 at 21:05): Brian Hicks (Jan 03 2024 at 21:05):hey, I'm trying to run the basic-cli examples with the latest roc binary and not getting a lot of success. Looks like there are some missing symbols during linking:
$ roc build hello-world.roc

Any ideas what could be going on here?

Brendan Hansknecht (Jan 03 2024 at 21:18):Any other system details?
Brian Hicks (Jan 03 2024 at 21:19):whoops, yes. Latest macOS.

Brendan Hansknecht (Jan 03 2024 at 21:37):hmm, can't repro on main, maybe an issue specfic to nightlies?
Brendan Hansknecht (Jan 03 2024 at 21:37):seems weird though cause it is failing in ld
Brian Hicks (Jan 03 2024 at 21:46):that is interesting. Is there anything special that needs to be done to build from source now? I'm getting a bunch of missing symbols there too :thinking:
Brian Hicks (Jan 03 2024 at 21:46):specifically it's telling me "Undefined symbols for architecture x86_64" when I try to cargo build. Not sure why it's not ARM
Brian Hicks (Jan 03 2024 at 21:47):(I can past the whole error if you like but it's large)
Brendan Hansknecht (Jan 03 2024 at 21:50):Interesting. I wonder if your system is for some reason emulating x86 with Rosetta for part of the build.
Brendan Hansknecht (Jan 03 2024 at 21:51):Then the symbols are missing for aarch64 despite existing for x86 or the reverse
Brian Hicks (Jan 03 2024 at 21:55):I've had some weird stuff on this system from the get-go. Something about how I had to set up the main repo at this job means I have to pass arch -arm64 before all Homebrew commands, for instance.
Brian Hicks (Jan 03 2024 at 21:56):but building Roc like that doesn't work:
$ arch -arm64 cargo build
arch: posix_spawnp: cargo: Bad CPU type in executable
and the arch -arm64 doesn't change the issue in the platform :thinking:
Brendan Hansknecht (Jan 03 2024 at 22:33):I would guess that arch -arm64 isn't recursive, so subcommands are still running via x86
Brian Hicks (Jan 03 2024 at 22:34):I've had a lot of weird arch issues on this computer, and it looks like this might merely be the latest. I'm going to wipe it and try again.
Brian Hicks (Jan 04 2024 at 23:36):I think this might be resolved. It turns out I had told Nix that this M2 mac was actually an Intel Mac, so it was set up all sideways to begin with. Unfortunately, I found that out by spending all day reimaging it. Sigh. (It wasn't just for this, though. I was having all sorts of weird problems that I think can be linked to this!)
Brian Hicks (Jan 04 2024 at 23:37):YESSSSSS
