All the documents available on the web are included in all the packages. (* Please note that options/instructions for out-of-date packages may differ slightly from the ones on the web. Always follow the instructions from the package itself.) The unified source tree contains the complete Haskell sources for the compiler, runtime system, standard prelude, and libraries (including Binary, FFI, IOExtras, etc) for nhc98, and current versions of GreenCard, hp2graph, hmake, and cpphs. In addition, it contains bootstrapping C sources in case you don't already have a Haskell compiler to build nhc98 with. The binary packages contain just the executables, interface files, and object files for the compiler, runtime system, standard prelude, libraries (including Binary, FFI, IOExtras, etc), GreenCard, hp2graph, hmake, and cpphs. In short, everything (except the sources) needed for normal compilation, heap profiling, time profiling. The installation instructions should be comprehensive, but if you have any problems, please mail `nhc-bugs@haskell.org`. (You do not need to be a member of the list to post to it.) ### Patches
patch name | patch to | date | fixes what problem?
--- | --- | --- | ---
none | nhc98 v1.22 | 2010-07-09 | no patches yet for nhc98-1.22
none | nhc98 v1.20 | 2007-11-23 | no patches yet for nhc98-1.20
confhc | nhc98 v1.18 | 2006-08-21 | Fix a bug in detecting the version of ghc-6.4.x on MacOS platforms. This manifested as the error "Makefile: *** missing separator".
himem | nhc98 v1.18 | 2006-07-28 | Fix the long-standing high-memory bug that afflicts nhc98 on many of the more recent Linux distributions.
newtype | nhc98 v1.18 | 2005-04-11 | Fix a bug in checking the consistency of newtypes, triggered by
    import Control.Monad(liftM2); newtype A a = A a;
library interface files | nhc98 v1.18 | 2005-03-28 | If you bootstrap nhc98 with a C compiler, then although the hierarchical library packages are built, their interface files are not. This tarfile should be unpacked on top of your source tree, to give you the missing .hi files.
hi | nhc98 v1.18 | 2005-03-11 | Export HMAKECONFDIR into hi (hmake interactive). This small patch is only needed for early downloads of nhc98src-1.18, on or before 15 Mar 2005.
