Stack install - Symbolic link dest not found...

[Cmdv]

Trying to use tensorflow as part of a project but getting stumped when using stack.

stack 2.3.1 x86_64 hpack-0.34.2 ghc 8.8.3 MacOS 10.15.x (Catalina)

running stack install I get the following error:

Cloning 8cde4d6a277f188ca495d29096a62b36e8534a3f from https://github.com/tensorflow/haskell.git

This may indicate that the source is a git archive which uses git-annex.

@Cmdv here is a workaround I used in order to get things working.

https://github.com/JamesCarl/deep-learning

Adding the repo as a submodule and removing the symbolic links and replacing it with the files prevented this error. If you find a simpler fix I'd definitely be interested in knowing what the appropriate method is to deal with issue.

Hope this helps!

[Cmdv]

@JamesCarl ah yes that's a good idea will try that out. It's a shame it has to be bought in like that but I'm by no means a stack pro so couldn't say why this is happening.

I am on macos, wonder if that has something to do with it?!

[Cmdv]

@JamesCarl I added a git submodule by:

> git submodule add https://github.com/tensorflow/haskell.git tensorflow

then pull down all of it's submodules

> git submodule update --init --recursive
> stack install

and it seems I still get the same error 😞

I'll try pulling down your repo see if I have something wrong else where.

edit: looks like now it's failing on snappy-0.2.0.2 with:

While building package snappy-0.2.0.2 using:
      /Users/cmdv/.stack/setup-exe-cache/x86_64-osx/Cabal-simple_mPHDZzAJ_3.0.1.0_ghc-8.8.3 --builddir=.stack-work/dist/x86_64-osx/Cabal-3.0.1.0 build --ghc-options " -fdiagnostics-color=always"
    Process exited with code: ExitFailure 1

so having to look into that

Had to point to a fork of snappy which fixed the macos build failure.

[JamesCarl]

@Cmdv the tensorflow submodule still has symbolic links in each of the folders the fork (https://github.com/JamesCarl/haskell.git) in the repo above has them removed. You could potentially just add the fork as a submodule to your project.

[Cmdv]

I managed to get your repo to build 🎉 turns out my nix home manager had made all the simlinks etc but it hadn't run this line:

https://github.com/tensorflow/haskell/blob/568c9b6f03e5d66a25685a776386e2ff50b61aa9/tools/install_macos_dependencies.sh#L39

so ran it manually and it now seems to install/build fine.

It works, will leave this open as it would be nice to not have to do all this. Unless it's there isn't a way to get around it then feel free to close. 👍
