[Haskell-iPhone] Fat binaries on iOS Target

[Joe]

Hi Carter,

When I have added “split-objs: True” in .cabal/config file, but when running cabal I got this message:

Preprocessing library pandoc-1.12.2.1...
unused terminals: 1

on the commandline: Warning: ignoring -fsplit-objs

And if I ignore that, at the end of build, I get another error message that stop the build.

cabal: dist-i386/build/Text/Pandoc_o_split: does not exist

It seems that split-objs cannot work with cross-compilation ghc.

What do you think?

Best regards,
Joe

I have finally successfully use Pandoc library in iOS app, but there’s an issue that the final app binary is more than 50MB when using Pandoc library. It’s around 5MB for simple haskell library. And without using Haskell, it’s around 100kb.
