Running num.Pow is giving a compiler error, is this a known issue? Current running on roc commit d782542 (PI)
Luke Boswell (Dec 08 2024 at 22:08):There could be a few things going on here.
Does this happen for you in the REPL? if you use $ roc repl?
Luke Boswell (Dec 08 2024 at 22:09):Can you share the error message too please?
Agustin Romero (Dec 08 2024 at 22:10):repl works fine!
here is the error
An internal compiler expectation was broken.
This is definitely a compiler bug.
Please file an issue here: <https://github.com/roc-lang/roc/issues/new/choose>
Undefined Symbol in relocation, (+124a, Relocation { kind: PltRelative, encoding: Generic, size: +20, target: Symbol(SymbolIndex(+71)), addend: +fffffffffffffffc, implicit_addend: false }): Ok(Symbol { name: "log", address: +0, size: +0, kind: Unknown, section: Undefined, scope: Unknown, weak: false, flags: Elf { st_info: +10, st_other: +0 } })

It only fails when you assign the value
Anthony Bullard (Dec 08 2024 at 22:10):To a discard binding
Anthony Bullard (Dec 08 2024 at 22:11):Does that track with what you see @Agustin Romero ?
Anthony Bullard (Dec 08 2024 at 22:12):Num.pow 1 1
and
a = Num.pow 1 1
works in Repl
But
_ = Num.pow 1 1
crashes in Repl. But I think binding to a _ in the repl always crashes. Is that known?
Anthony Bullard (Dec 08 2024 at 22:12):Oh yeah
Agustin Romero (Dec 08 2024 at 22:13):not really.
this crashes

ambient functions don't unify
Location: crates/compiler/unify/src/unify.rs:202:18
Only handles ident binding
Agustin Romero (Dec 08 2024 at 22:14):and assigning to a variable crashes aswell

Are you using the legacy linker?
Luke Boswell (Dec 08 2024 at 22:16):
Undefined Symbol in relocation
this makes me think it may be linker related
Agustin Romero (Dec 08 2024 at 22:16):no i wasn't let me give that a try
Luke Boswell (Dec 08 2024 at 22:16):Oh... the log has me thinking maybe the way I'm handling the Err from main is the issue.
Can you add a type annotation to main! and try again?
Agustin Romero (Dec 08 2024 at 22:17):legacy linker makes it run
Luke Boswell (Dec 08 2024 at 22:18):I'm confused where this log symbol is coming from
Agustin Romero (Dec 08 2024 at 22:20):adding the type annotation didn't help

And you're running x64 linux right?
Luke Boswell (Dec 08 2024 at 22:23):It's working ok for me on my arm64 mac
Agustin Romero (Dec 08 2024 at 22:23):x64 linux, correct
Luke Boswell (Dec 08 2024 at 22:23):We have a related issue https://github.com/roc-lang/roc/issues/7068
Agustin Romero (Dec 08 2024 at 22:25):Totally missed it. Would that be a good first issue for me to solve?
Luke Boswell (Dec 08 2024 at 22:26):I suspect this is a known issue, I'm having trouble tracking down the related Issue.
@Brendan Hansknecht would probably know from looking at this error message if we are already tracking.
Agustin Romero (Dec 08 2024 at 22:29):I'm asking if adding the recommendation could be a good first issue, not expecting to fix the actual issue myself :laughing:

Anton has labelled it as an intermediate issue.
Maybe for providing more information as recommended in this issue it's as simple as including a note in internal_error macro message. That would be easy to do.
Agustin Romero (Dec 08 2024 at 22:33):if you think it's possible i'll take a look, have some spare time right now
Brendan Hansknecht (Dec 08 2024 at 23:47):why does pow need log....strange
Agustin Romero (Dec 09 2024 at 00:06):Should i create a fork to create a PR, i'd be changing a single line
Luke Boswell (Dec 09 2024 at 00:23):If you don't have contributor / write access to the repo you will need a fork.
Agustin Romero (Dec 09 2024 at 00:28):got it.
