Building on OS X

[Tom Davies]

While I think developing in a Linux VM makes most sense, I am trying to build Codeworld on OS X just for fun.

The first obvious error I get is:

src/CodeWorld/Message.hs:16:8: error:

    Failed to load interface for ‘Prelude’

    Perhaps you haven't installed the "js_p" libraries for package ‘base-4.9.0.0’?

    Use -v to see a list of the files searched for.

Does that have an obvious cause?

Log context:

RUNNING: cabal_install --ghcjs ./codeworld-prediction ./codeworld-error-sanitizer ./codeworld-api ./codeworld-base ./codeworld-game-api QuickCheck

Warning: --root-cmd is no longer supported, see

https://github.com/haskell/cabal/issues/3353 (if you didn't type --root-cmd,

comment out root-cmd in your ~/.cabal/config file)

Warning: the --global flag is deprecated -- it is generally considered a bad

idea to install packages into the global store

Thanks for the report, Tom.  I'm not sure what's changed.  The problem is that the build script is trying to install profiling versions of the libraries, but we bootstrap GHCJS without profiling versions.

Can you try modifying base.sh to add "--disable-library-profiling" to the definition of the cabal_install macro?

That fixed the problem -- I'll open a PR (when I can remember not to commit with my work email!)

When I run the logo example on OS X I get some errors -- but it runs correctly:

Line 30, Column 48: error: Missing parentheses in function application

Line 42, Column 31: error: Missing parentheses in function application

Line 43, Column 31: error: Missing parentheses in function application
