Many thanks to Darrin Chandler and dcoppa@ for testing, reporting about
broken stuff, missing dependencies here and in ports depending on ghc.
Notes and rants:
- Bootstrapping is done using precompiled binaries, since .hc
bootstrapping still doesn't work. I really hate this.
THIS MEANS THAT GHC IS NOW AND WILL STAY LEGACY-ONLY (i386 and amd64)
At least until someone fixes it. I tried for more than two year
(well, only in my spare time and during my vacations) and failed.
- libgmp is currently disabled, because I didn't yet hack the GHC build
system to use the system libgmp instead of the patched one included
in GHC.
- The haddock ncluded in the ghc distfile is replaced by the version
of haddock found in devel/haddock. Haddock itself is @commented
in the ghc PLIST. Unfortunately, this needs an ugly hack that
introduces an otherwise useless pseudo flavor `no_deps' in
devel/haddock.
- CLDouble has been removed from GHC some time ago, because it was
an alias for double (AFAIK there's now support for long double
in GHC). As this isn't a really big problem, it currently breaks
c2hs, which I'll mark broken temporarily before committing the
ghc update.
- The external codeset defaults to latin1 (suggested by Simon Marlow)
and can be overridden by setting the HS_ENCODING to any codeset
supported by libiconv.
- ghc.port.mk still needs some love, especially for letting a port add
additional parameters to certain invocations of ${MODGHC_SETUP_PROG}.

The Glasgow Haskell Compiler is a state-of-the-art, open source, compiler and
|
|
interactive environment for the functional language Haskell. Highlights:
|
|
|
|
* GHC supports the entire Haskell 98 language plus a wide variety of
|
|
extensions.
|
|
* GHC works on several platforms including Windows and a few varieties of
|
|
Unix, and a few different processor architectures. There are detailed
|
|
instructions for porting GHC to a new platform. Which doesn't work.
|
|
* GHC has extensive optimisation capabilities, including inter-module
|
|
optimisation.
|
|
* GHC compiles Haskell code either by using an intermediate C compiler
|
|
(GCC), or by generating native code on most currently supported
|
|
platforms. The interactive environment compiles Haskell to
|
|
bytecode, and supports execution of mixed bytecode/compiled
|
|
programs.
|
|
* Profiling is supported, both by time/allocation and various kinds of
|
|
heap profiling.
|
|
* GHC comes with a minimal range of libraries, but a wide range of
|
|
additional libraries are available as separate packages, including
|
|
the full set of the Haskell Platform.
