When built via `nix-shell`, Eta seems to miss pkg-db (missing `base` and other core libraries)

[fmthoma]

Steps I took to build Eta on NixOS 17.03:

• Clone repo recursively, check out 0.0.6b6
• nix-shell -A eta-build-shell
• etlas update

So far, everything worked fine.

• Now I created a helloworld project (mkdir helloworld && cd helloworld && etlas init)
• etlas build fails with the following error:

  src/Main.hs:1:1:
  Could not find module ‘Prelude’
  Use -v to see a list of the files searched for.
  

• The same error occurs when directly invoking eta src/Main.hs
• etlas install --dependencies-only says:

  Resolving dependencies...
  All the requested packages are already installed:
  Use --reinstall if you want to reinstall anyway.
  

After trying to re-build Eta several times, I found out the following:

• Eta seems to search for a packages.conf.d with a packages.cache in ~/.eta.
• Immediately when entering the nix shell, ~/.eta/packages.conf.d (in fact ~/.eta) seems to be missing.
• After running eta (or etlas build), the directory and a packages.cache is created, but the core libraries are missing, hence the »missing Prelude«.

Creating a sandbox (etlas sandbox init) does not help either.

Did I miss some step? Or is the Nix shell currently broken?

[rahulmutt]

It looks like you don't have the boot libraries for Eta like base installed properly. It may be that a recent change might have broken an assumption in the Nix scripts.

@puffnfresh Can you take a look at this?

Unfortunately, we don't test the nix script with CI (yet) so we won't detect any breakages until people try it out.

[fmthoma]

@rahulmutt @puffnfresh The Nix script builds a package called eta-boot-0.0.6 with lib/ghc-7.10.3/package.conf.d and the following content:

> ls -l /nix/store/ynbzg5jbgcyvdgcy5jwjlmjc6b5b8202-eta-boot-0.0.6/lib/ghc-7.10.3/package.conf.d
total 4

Maybe this is just missing from some environment variable? OTOH, this does not look like the usual GHC package.conf.d:

> ls -l /nix/store/0wyczcrnihn3b9xh2fxq3xqm37q9dcmb-ghc-8.0.2/lib/ghc-8.0.2/package.conf.d

It may be that a recent change might have broken an assumption in the Nix scripts.

If you have a particular change in mind, can you point me to a version before that change that I could try?

[puffnfresh]

Within the shell you need to run:

$ eta-build uninstall
$ eta-build install

Have you done that?

[fmthoma]

@puffnfresh Thank you for the hint! No I haven't, but doing it now. cd src && eta Main.hs now works correctly, but etlas build still complains about not finding the Prelude module.

This step is not mentioned in the documentation for Nix, could you adapt the documentation?

One more thing: From the docs, it is not immediately clear that nix-shell -A eta-build-shell should be run in a clone of the Eta repository. It's quite easy to figure this out, but it might be worth mentioning explicitly.

[rahulmutt]

Can you share the output of etlas build -v3 via a Gist?

[fmthoma]

@rahulmutt Here you go: https://gist.github.com/fmthoma/894db92f66ff0d2deb2931d73bda1a46

[puffnfresh]

@fmthoma could you also post eta-pkg list please?

[puffnfresh]

Actually eta-pkg dump is probably more useful for debugging, if you could.

[fmthoma]

@puffnfresh @rahulmutt Appended both to the gist

[puffnfresh]

@fmthoma I just noticed it's using package.conf from dist - it might be trying stuff from before you did the eta-build install. Can you try a etlas clean then etlas configure?

Thanks for posting the outputs.

[mandubian]

I've hit same issue with missing Prelude after Nix install.
