Shadowed dependencies during builds with Cabal 2.0 WAS: cabal 2.0 and alex on macos

[v0d1ch]

I am trying to build a project with cabal new-build and I have ghc-8.2.1 and

cabal-install version 2.0.0.0
compiled using version 2.0.0.2 of the Cabal library

It is failing to build alex (among some other packages but this one fails first)

─λ cabal new-build gtk                                                                                                [slay]-4 | 0 < 21:00:22

    You may wish to bookmark that file once it gets built (after the
    first cabal install).

That's an interesting failure mode, why would the dependencies be shadowed?

/cc @dcoutts

[v0d1ch]

For the info my macOS version is 10.12.6 with xcode 8.3.3. This project builds on travis with osx 10.11 and xcode 7.3

[23Skidoo]

Can you please post a -v3 log?

[v0d1ch]

Sure if you can explain what a -v3 log is ?

[23Skidoo]

Just run cabal new-build with -v3 (highest verbosity option).

[v0d1ch]

Thanks, that produced following output piped to file

Hi,

I have also similar issue regarding shadow dependencies.

I am using Haskell Platform's generic on my Ubuntu guest (using virtualbox) of my Windows 10 machine.

the plan.json is here:

is this problem relevant to what OP is made here?

I just saw this reference from the Stack issue (thank you!). I initially heard about this problem from a user report trying to build Yesod. The failure log is:

@23Skidoo I was able to knock this down to a minimal reproducing case using only Cabal-the-library (neither Stack nor cabal-install), which hopefully will make it easier to debug this:

https://github.com/snoyberg/stack-issue-2781

Let me know if you have any questions about that, happy to assist.

[23Skidoo]

@snoyberg Thank you! I'll try to look into that once I'm back from ICFP.

[snoyberg]

Sounds great! Enjoy ICFP 🍻

[snoyberg]

Any objection to updating the title of this issue to mention "shadowed dependencies?" I think it will make it easier for others to find it (and thereby avoid duplicate reports).
