v2-sdist does not create Setup.hs

[eborden]

A project should not require a default Setup.hs. cabal v2-build works fine without one, but cabal v2-sdist fails to generate a default Setup.hs for the tarball.

Version

$ cabal --version
cabal-install version 2.4.1.0
compiled using version 2.4.1.0 of the Cabal library 

When uploaded to hackage

Source issue

see: haskell/network#357

Should be easy to fix. /cc @typedrat.

I can confirm that this is a regression relative to cabal v1-sdist (which does synthesize a Setup.hs on the fly)

[phadej]

I was able to upload Setup.hs-less packages to Hackage...

[hvr]

To clarify, it appears that it's been possible at least since 2015 to upload Setup.hs-less packages (but only for build-type:Simple). And I can confirm that cabal-install 1.16 happily installs such packages without breaking a sweat. OP's package however doesn't fall into this category (due to build-type:Configure) which is why they got a validation error.

[23Skidoo]

Hackage/cabal check should check that build-type: Configure packages have a Setup.hs or Setup.lhs.

@23Skidoo and it does :-)
