Running nix-shell fails at error: could not compile const-random-macro on OSX Catalina

[stephenpurkiss]

I am wondering if anyone else is running OSX Catalina and managed to get nix-shell working OK. Due to the age of my laptop (Mid-2012) I am unable to upgrade to Big Sur, I don't have much space left on the machine to do dual-boot, plus I believe I won't be the only one who will be using Catalina for Holochain dev so sticking with it for the moment, will have to rethink if can't sort this issue out though as I'm still stuck at the first exercise lol.

Previously I posted on the Big Sur issue however as I discover and learn more I see the issues don't seem to be as related as I thought, I had a little google again today and saw an issue on the rust language to do with hashing and wondering if it's providing clues so thought I'd post here in case it makes any more sense to those in the know as the holonix command works fine it's only when I run nix-shell in the developer exercises it breaks. But then again I'm not running nix-shell on anything else so haven't isolated this, not sure what else I could try so feel free to suggest something so I can see whether it's developer-exercises specific or not.

@stephenbpurkiss

I'm running Catalina 10.15.7...

Since this ticket is called "holonix fails on big sur (darwin 11.2.1)" and your report shows a different error message, you're likely dealing with a different issue than the reporter on this one. It would be helpful if you could file a new issue so we can deal with that separately.

From the Rust hashbrown issue:

Disclaimer: This is actually not an issue with hashbrown but with cargo.

Topic: no_std support

While hashbrown itself is able to compile successfully for no_std targets, and even uses the CI pipeline to verify its compatibility to the thumbv6m-none-eabi target, it might still trigger issues if used with other dependencies when the default ahash feature is enabled.

Issue

The dependency tree of ahash injects the getrandom crate if the default feature set is enabled. This crate is heavily platform dependent and does not support targets like the thumbv6 or thumbv7 families.

How does this happen?

The underlying issue is an a long standing and well known cargo bug (rust-lang/cargo#5760) which automatically calculates a required feature set for each (sub-)dependency inside the dependency tree regardless of the dependency origin.

If ahash - with default feature set - is used, it will include the const-random crate and therefore the proc macro crate const-random-macro into the dependency tree. This will request the getrandom feature for the crates rand v^0.7 and indirectly also rand_core v^0.5.1.

As dependencies of proc macros are compiled for the host and not the target architecture this works fine as long as the host architecture is contained in the following list and the no_std build should be successful (as you can see inside the CI).

But it is going to fail as soon as one of the following two conditions are true:

• The host architecture is not supported.
• The target architecture is not supported and the dependency tree contains at least one non proc macro dependency, which requires either rand v^0.7 or rand_core v^0.5.1, because than the underlying cargo issue kicks in. Cargo is going to inject the getrandom feature requirement for these crates, originating from the dependency list of const-random-macro, into the other dependency so that cargo is trying to compile getrandom not only for the host architecture but also for the target architecture.

Request

As long as rust-lang/cargo#5760 is still a thing it would be great if at least the hashbrown documentation could get a warning paragraph explaining this topic including how to work around this issue.

Potential workarounds I can see:

• hashbrown could introduce a way to disable the compile-time-rng feature of ahash if default features are disabled.
• The relying crate could disable the ahash feature of hashbrown and reintroduce another hasher or ahash without compile-time-rng feature.

Both might result in ahash losing the compile time random seed for the hash values.

Here's the output - am using @tixel's new fork but it's the same error as before:

So I've been doing a little more digging and learning a little more about how all this works and I'm wondering if the problem is to do with the version of holonix you're using doesn't have libiconv dependency as this was added by @steveej after I posted my issue - see holo-nixpkgs: bump to include libiconv dependency on darwin #212

I do not currently have the fu to figure out how I could test this theory locally.

Just to make sure:
do you have the macos developer tools installed?

Another interesting link might be this one:
https://cmichel.io/fixing-cpp-compilation-bugs-for-the-mac-os-catalina-upgrade/

I don't run MacOS so I have no way of validating.

Yes ;) Although I did have a crisis of confidence the other week and wondered if I'd perhaps done a reinstall of OSX since I last played with code but it's there, xcode-select version 2373.

Interesting - it makes sense so I tried, ensured the environment variables were correctly added by echoing them but still the same error which is why I'm thinking it's where @steveej says:

In the meantime we merged something that will likely help with the libiconv linking, see #212.

...and in #212 @steveej says:
"I want to unblock the macOS devs with this PR"

So when I did some more digging today and saw the developer exercises are referencing a specific commit of holonix I realised this "unblocking" of macOS devs wouldn't be included in the one used here.

This is me presuming that liconv has something to do with libiconv. If not then I am incorrect in my assumptions.

Really appreciate your time and attention, could very well have been that environment variable issue, good find!

[guillemcordoba]

@stephenbpurkiss can you try again doing nix-shell from the master branch? I just bumped the holonix version, which should point to the latest develop and include the liconv fix. I think that should fix the issue, it should be very close to everything you get with nix-shell https://nightly.holochain.love.

[stephenpurkiss]

Woo yay, got further than last time!
