0.7.2.0 not compiling on Windows

[hvr]

Which GHC version?

[thoughtpolice]

The problem is that Haskeline 0.7.2.0 expects Applicative to be unconditionally exported from Prelude, but this only is true in GHC 7.10. I think this patch may have been my fault and I slightly botched it.

The solution is shipping 0.7.2.1 with a patch like:

#if __GLASGOW_HASKELL__ <= 709
import Control.Applicative (Applicative)
#endif

in the import decls.

Thanks for the report; I've released 0.7.2.1 which should hopefully fix that issue. Sorry, I'm currently missing a good way to test on Windows. Can someone please confirm whether the library builds now on pre-ghc-7.10?

I ended up just using an unqualified, un-CPP'd import of Control.Applicative since that's what's still done in other parts of the library; we can work on making it warning-free in a later CL.

@judah I can confirm that 0.7.2.1 now compiles on GHC 7.8.3/MSYS2/Windows (whereas 0.7.2.0 didn't)

[eccstartup]

I find it doesn't compile on OS X. ghc 7.8.4

I have gmp installed with homebrew.

@eccstartup I suspect this is a case of http://stackoverflow.com/questions/26899948/ghc-anything-results-in-ld-library-not-found-for-lgmp

[cartazio]

@eccstartup @hvr could one of you do otool -L on your ghc binary? (otool -L is for tracking down ) It sounds like you're using a brew built GHC, instead of an official build. Official builds for OS X use intree-gmp. Or just brew installing gmp might get you done

[eccstartup]

OK, I removed the ghc from homebrew. The ghc recommended works fine.

[FranklinChen]

As mentioned, xcode-select --install solves the problem with the Homebrew GHC 7.8.4.

[eccstartup]

@FranklinChen I am happy to see your comment. But if I have installed Xcode, isn't command-line-tools bundled with Xcode? Or I have to install it again? Not sure.

[FranklinChen]

@eccstartup Yes, for whatever reason, even if you already have Xcode, the xcode-select --install command seems necessary in order to trigger the correct setting for Homebrew, namely,

$ brew --config
...
CLT: 6.2.0.0.1.1424975374

@FranklinChen Thanks. Here is N/A.
