----------------------------------------------------------------------------- -- | -- Module : Distribution.Simple.GHC -- Copyright : Isaac Jones 2003-2007 -- -- Maintainer : cabal-devel@haskell.org -- Portability : portable -- -- This is a fairly large module. It contains most of the GHC-specific code for -- configuring, building and installing packages. It also exports a function -- for finding out what packages are already installed. Configuring involves -- finding the @ghc@ and @ghc-pkg@ programs, finding what language extensions -- this version of ghc supports and returning a 'Compiler' value. -- -- 'getInstalledPackages' involves calling the @ghc-pkg@ program to find out -- what packages are installed. -- -- Building is somewhat complex as there is quite a bit of information to take -- into account. We have to build libs and programs, possibly for profiling and -- shared libs. We have to support building libraries that will be usable by -- GHCi and also ghc's @-split-objs@ feature. We have to compile any C files -- using ghc. Linking, especially for @split-objs@ is remarkably complex, -- partly because there tend to be 1,000's of @.o@ files and this can often be -- more than we can pass to the @ld@ or @ar@ programs in one go. -- -- Installing for libs and exes involves finding the right files and copying -- them to the right places. One of the more tricky things about this module is -- remembering the layout of files in the build directory (which is not -- explicitly documented) and thus what search dirs are used for various kinds -- of files. {- Copyright (c) 2003-2005, Isaac Jones All rights reserved.
