Cabal install fails in sandbox

[Ongy]

Trying to build happy I encountered a problem during the cabal install step.

This is on archlinux with ghc 8.0.2 and cabal from recent git HEAD.

Full log, so you can see what I'm doing. The interesting line is probably:

happy: /tmp/happy-1.19.5/.cabal-sandbox/share/x86_64-linux-ghc-8.0.2/happy-1.19.5/HappyTemplate-arrays-coerce: openFile: does not exist (No such file or directory)

I suspect its the git HEAD version of cabal. Works fine for me with cabal version 1.24.0.2.

Probably worth raising this as a bug against cabal though.

[kindaro]

I experience the same issue, though with new-build. I use cabal-install 2.3.0.0 and the current happy, cloned right from here just now.

[simonmar]

@kindaro Happy is non-standard because it is bootstrapped. See the README.md file for instructions on how to build: https://github.com/simonmar/happy/blob/master/README.md

[kindaro]

@simonmar   What you are saying is that this package is not going to be handled by new-build?

If there is only one supported way to build, I would humbly suggest to expand the Readme correspondingly, because practically all other packages can be built by several methods (cabal, cabal/new, stack, nix...), and us humans tend to have a preferred build method, so it is best to get explicitly discouraged at an early stage.

Also, the support for the old style commands will get dropped from cabal-install eventually, so at some point some other build method will have to be supported.

P.S. I am sorry if I am being obvious.

[simonmar]

@simonmar What you are saying is that this package is not going to be handled by new-build?

No, not at all! It works fine with new-build. But you have to build it from the package uploaded to Hackage, not directly from a git checkout. For more details, see the readme.

[simonmar]

Oh, I got confused between Alex and Happy. Alex is the one with the build instructions in the readme, it looks like we haven't done this for Happy yet. But it should still work to build it from the Hackage package instead of a git clone.
