-fhint flag does not work with cabal-dev

[ozataman]

Currently, snap requires you compile with -fhint to enable devel mode. I know of no way to get this to work with cabal-dev. In my opinion, this is unacceptable. My reasons are:

• cabal-dev or something similar is absolutely a given for serious projects
• Devel mode is absolutely critical to GUI-heavy projects. Without it, we are not a competitive framework (both with haskell and many non-haskell leading frameworks).

The current workaround is to clone snap to a local repo, tweak the default -fhint setting and do cabal-dev add-source.

With recent changes to cabal-dev, the following flag passing method now mitigates this issue:

--flags="-fhint"

the final example command being:

cabal-dev install snap --flags="-fhint".

I will close the ticket once I am confident this method works.

cabal-dev has now fixed this issue and as of version 0.9, this is the best way to enable snap devel mode:

cabal-dev install snap -fhint
