Support OS X fully

[mietek]

Most of the work is already done. Everything is expected to work on OS X, except installing native OS packages declared with HALCYON_SANDBOX_EXTRA_OS_PACKAGES or HALCYON_EXTRA_OS_PACKAGES.

• Improve the setup process for GNU bash 3, as it doesn’t recognise the source <( … ) syntax.

  $ curl -sL https://github.com/mietek/halcyon/raw/master/setup.sh >/tmp/halcyon-setup.sh && . /tmp/halcyon-setup.sh
  $ /app/halcyon/halcyon paths >/tmp/halcyon-paths.sh && . /tmp/halcyon-paths.sh
  

• Provide public storage archives for OS X 10.9 and 10.10.

• Speed up stripping GHC on OS X (Speed up stripping GHC on OS X #43)

• Prevent the OS X linker from complaining about non-existent directories passed to cabal install.

  ld: warning: directory not found for option '-L/app/sandbox/usr/lib'
  

• Prevent the OS X linker from complaining about non-existent directories in LD_LIBRARY_PATH.

  ld: warning: directory not found for option '-L/app/lib'
  ld: warning: directory not found for option '-L/app/usr/lib'
  ld: warning: directory not found for option '-L/app/ghc/usr/lib'
  ld: warning: directory not found for option '-L/app/sandbox/usr/lib'
  

• Ensure the dependency on GNU bash 4, GNU date, and GNU sort is documented, or removed.

  $ brew install bash coreutils
  

• Wrap around brew to support installing native OS packages.

Depends on mietek/bashmenot#2.

With b9ddddd, one of the OS X linker complaints is now gone. Getting rid of the other ones will probably require rethinking paths.sh.

With 3419002 and e139265, there is now a workaround for the problem with stripping GHC on OS X (#43).

Not to throw a wrench in the works here, but this document might be something to peruse

It might be worth looking into using something other than /app for halcyon on OS X going forward.

Main change is thus:

"... prevent the modification or removal of certain system files even by administrative overrides. This means that no user, application, or process will be able to write files or modify files in the root System folder or the /bin, /sbin, and /usr directories, which are hidden by default in OS X’s Finder. The /usr/local folder will still be accessible though."

I’m sorry. This project is no longer maintained.
