TH splice changeWorkingDirectory: does not exist when cross compiling elm to musl64

[ParetoOptimalDev]

I followed the haskell.nix cross compliation tutorial, but had to adapt some things to flakes. That could very well be where my error is if this isn't a bug.

Here is my repo for reproducing this:

https://github.com/ParetoOptimalDev/compiler/tree/multi-arch-static-bins-with-nix

From x86_64-linux cross compiling tomusl64 I get:

changeWorkingDirectory: does not exist (No such file or directory)

-- PROBLEM LOADING PACKAGE LIST ------------------------------------------------

I need the list of published packages to verify your dependencies, so I tried to
fetch:

    https://package.elm-lang.org/all-packages

But my HTTP library is giving me the following error message:

    ConnectionFailure Network.Socket.getAddrInfo (called with preferred socket type/protocol: AddrInfo {addrFlags = [AI_ADDRCONFIG], addrFamily = AF_UNSPEC, addrSocketType = Stream, addrProtocol = 0, addrAddress = <assumed to be undefined>, addrCanonName = <assumed to be undefined>}, host name: Just "package.elm-lang.org", service name: Just "443"): does not exist (Temporary failure in name resolution)

Are you somewhere with a slow internet connection? Or no internet? Does the link
I am trying to fetch work in your browser? Maybe the site is down? Does your
internet connection have a firewall that blocks certain domains? It is usually
something like that!

I'm not sure if this is a problem, but it looks like in the full logs before that failure elm is trying to fetch something and failing:

I need the list of published packages to verify your dependencies, so I tried to
fetch:

    https://package.elm-lang.org/all-packages

But my HTTP library is giving me the following error message:

    ConnectionFailure Network.Socket.getAddrInfo (called with preferred socket type/protocol: AddrInfo {addrFlags = [AI_ADDRCONFIG], addrFamily = AF_UNSPEC, addrSocketType = Stream, addrProtocol = 0, addrAddress = <assumed to be undefined>, addrCanonName = <assumed to be undefined>}, host name: Just "package.elm-lang.org", service name: Just "443"): does not exist (Temporary failure in name resolution)

Are you somewhere with a slow internet connection? Or no internet? Does the link
I am trying to fetch work in your browser? Maybe the site is down? Does your
internet connection have a firewall that blocks certain domains? It is usually
something like that!

I also added the builder directory like you added the reactor one:

                              '';

An error still happened, so now I'm suspicious of bsToExp in the problematic splice $(bsToExp =<< runIO Build.buildReactorFrontEnd) . There was similar discussion about file-embedin #1077 (comment)

However it looks like you and @purefn fixed things here? I'll start inspecting the components/sources of the elm project to make sure I guess.

I'm println debugging the template Haskell splice now to see how far it gets. This should narrow things down.

Everything builds fine If I remove that call:

It seems to need network access for something... still tracking down what.

Actually maybe nixpkgs handles this for elm since they successfully build it....

And of course... @domenkozar has detailed exactly that in nixpkgs documentation for compiling/updating elm:

The elm binary embeds a piece of pre-compiled elm code, used by 'elm reactor'. This means that the build process for 'elm' effectively executes 'elm make'. that in turn expects to retrieve the elm dependencies of that code (elm/core, etc.) from package.elm-lang.org, as well as a cached bit of metadata (versions.dat).

The makeDotElm function lets us retrieve these dependencies in the standard nix way. we have to copy them in (rather than symlink) and make them writable because the elm compiler writes other .dat files alongside the source code. versions.dat was produced during an impure build of this same code; the build complains that it can't update this cache, but continues past that warning.

Finally, we set ELM_HOME to point to these pre-fetched artifacts so that the default of ~/.elm isn't used.

It'll take a second to digest how to replicate this with Haskell.nix.

It looks like I'll have to bring in makeDotElm and override cabal.preConfigure with to run fetchElmDeps.
